The teaching formulas are learning trials for blotter evaluation. They are not safety assessed; physical testing and specialist review are required before any commercial use.

Introduction

Creating a perfume begins with an idea. Turning that idea into a repeatable product requires a sequence of practical decisions: which materials to use, how to evaluate them, how to record a formula, who will manufacture it, and how to prepare the finished product for sale.

This guide is for beginners who want to learn that process, including hobby perfumers who have already made their first blends. It focuses on fine fragrance, with alcohol-based perfume as the main working format. The examples follow a project from individual materials through simple accords to a complete fragrance, then into packaging, manufacturing and documentation.

You do not need to understand every stage before beginning. You do need a clear next step and a reliable record of what you have done.

What you will learn

You will learn to select equipment, organise a small material collection, prepare working dilutions and evaluate smells over time. You will compare materials, build small accords and revise a fragrance through documented trials. Later chapters explain how the development work connects to manufacturing, packaging and the requirements for an EU launch.

The starter palette contains 30 materials, with an initial group of 20 for readers who prefer to begin with a smaller purchase. Each material has a teaching purpose. Together, they provide opportunities to explore citrus, floral, green, woody, musky, sweet and balsamic effects.

The example development is a way to practise making decisions. It is a proposed fragrance direction that must be evaluated through physical trials; a written formula alone cannot establish how balanced, stable or suitable a perfume will be. Learning the process also gives you a basis for developing a different fragrance later.

Progress through small, useful trials

An early blend may smell promising at first and disappointing several hours later. A change intended to improve freshness may weaken the heart. Two materials you expected to recognise may become difficult to distinguish in a mixture.

Treat each trial as a question. What happens when one material is reduced? Does an added note remain noticeable after the opening fades? Does the revised version better match the brief?

A useful result is one you can describe and reproduce. Keep a reference sample, record the exact weights and state what you intended to change. When a trial disappoints, those records make the next decision easier.

Use Scent Inventory from the beginning

Create a record for each material when it arrives. Record its supplier, the supplied concentration and the available batch identification, and attach the documentation you receive. Add your own observations as you learn its smell.

During development, use Scent Inventory to keep formulas, versions, trial records and material consumption connected. A note such as “greener opening, rose less clear after two hours” becomes much more useful when it belongs to an identifiable version prepared from known materials.

The same recordkeeping habit supports the later manufacturing stages. Software helps organise the evidence; the records remain dependent on accurate inputs and complete supporting information.

How to use this guide

Begin with the production decision in Chapter 1. If you want to develop your own fragrance, continue through equipment, materials, smelling exercises and accords. If you prefer external development, go from Chapter 1 to Chapter 8, then Chapters 9–11. Use Chapter 4 to improve your sample evaluation without assuming that you need a formulation workspace or the starter palette. Section 1.8 gives the reading routes.

Both routes eventually reach packaging, product assessment and launch preparation. The guide treats the EU as the market framework and flags matters that require country-specific checking. Detailed production-space requirements appear alongside manufacturing practice later in the guide; basic safe handling belongs at the start of practical work.

Keep three milestones separate: a learning trial, a selected development formula and a product ready for sale. Completing one milestone gives you a basis for working towards the next.

The practical recipes begin as learning trials for blotter evaluation. Before making plans to supply a perfume, including free promotional samples, read Chapter 10.1 and identify the commercial requirements. The detailed compliance work comes later in the book, but its evidence needs should inform development before you commission tests or production.

1. Choose Your Production Path

Before buying equipment or requesting quotations, answer two questions:

  1. Who will develop the fragrance formula?
  2. Who will manufacture and fill the finished perfume?

You can take responsibility for both, outsource both, or divide the work. Separating these decisions makes it easier to choose a route that fits your interest, time and resources.

1.1 Understand the stages

Fragrance development means translating an idea into a formula through material selection, trial preparation, evaluation and revision.

Concentrate production, often called compounding, means weighing and blending the fragrance materials according to that formula.

Finished-product manufacturing includes preparing the perfume at its intended concentration and carrying out the relevant processing and controls. Filling, fitting pumps, labelling and packing may be provided by the same business or by separate suppliers.

Supplier terminology varies. Ask what a service includes in practical terms and which deliverables you will receive.

1.2 The main routes

RouteYour main contributionWhat to clarify
Private labelSelect an existing fragrance and define the presentationAvailable customisation, exclusivity, packaging choices and included documentation
Modified catalogue fragranceChoose an existing starting point and request changesPermitted modifications, sample rounds and consequences for timing and documentation
Custom external developmentWrite the brief and evaluate proposalsDevelopment scope, revision process, formula access and usage rights
Own formula with external productionDevelop and document the formula, then transfer itWhether the manufacturer accepts outside formulas and can source the specified materials
Own development and productionCarry out the creative and practical production workEquipment, workspace, repeatability, records and the external expertise required for launch preparation

These are working descriptions for comparing offers. A supplier may combine several routes or use the same label for a different service package.

1.3 Developing the fragrance yourself

Choose this route if learning perfumery is part of the goal. You will spend time smelling materials, preparing small trials and assessing changes that may initially seem subtle.

Your first investment is in a manageable learning setup: a suitable balance, basic handling equipment, sample containers, scent strips and a focused palette. Begin with small quantities and clear records. Let your experiments identify what additional materials or equipment you need.

Developing the formula yourself allows you to investigate each ingredient's contribution. It also makes you responsible for specifying what was actually used. A supplier name, commercial product name and supplied concentration may matter when reproducing a trial or transferring it to another manufacturer.

Do not assume that a formula can automatically be transferred to any production partner. If external manufacturing is likely, ask potential partners early about their acceptance criteria for customer formulas. This can reveal material-sourcing or documentation gaps before you invest heavily in development.

1.4 Working with an external developer

External development suits readers whose main interest is selecting and directing a fragrance for their brand. Your role centres on a clear brief and consistent feedback.

Describe the experience you want: the character of the opening, the desired floral or woody emphasis, and the impression the fragrance should leave as it develops. Explain what worked in each sample and what should change. Keep sample identifiers and evaluation notes together so that feedback refers to a specific proposal.

Before commissioning the work, agree on the number of sampling rounds, the deliverables and the procedure for further changes. Clarify whether you receive the formula, a right to buy the concentrate, or another defined arrangement. Paying a development fee does not by itself tell you which rights are included; those terms need to be explicit in the agreement.

Named providers, quotation examples and the practical enquiry process are covered in the manufacturer chapter.

1.5 Compare the full scope

For each route, consider where your time and money will go. Own development involves materials, equipment and learning trials. External development involves briefing, sample evaluation and the services specified in the offer. Either route can also involve packaging, testing, assessment, filling and documentation work.

Compare quotations against the same product description: intended bottle size, quantity, concentration, packaging and required services. Ask what each minimum order applies to. A minimum for concentrate and a minimum for decorated bottles describe different commitments.

Also ask when the quoted lead time starts. Development, packaging procurement and production may have separate schedules. Use the answers to build a realistic sequence rather than relying on one overall delivery estimate.

1.6 Assign responsibilities explicitly

Create a simple project responsibility sheet before moving towards production. Identify who develops the formula, supplies the concentrate, fills the bottles, checks the packaging and maintains each part of the documentation. Where specialist support is required, record who will arrange it.

EU product notification is handled through the Cosmetic Products Notification Portal (CPNP). The European Commission identifies responsible persons and, in certain circumstances, distributors as the parties required to submit information through this system. The later compliance chapter explains how notification fits into the broader preparation process. European Commission: CPNP

Do not treat the phrase “full service” as a substitute for a written allocation of tasks. Ask which documents and services are included, who holds them and how future changes will be handled.

1.7 A hybrid route

You may enjoy developing a fragrance while preferring to outsource compounding or filling. This gives you a practical reason to keep the formula, material specifications and version history organised from the first trial.

Before approving a transferred formula for production, compare a representative sample from the manufacturing partner with the agreed reference. Record and evaluate any proposed material substitutions or other changes.

1.8 Follow the route that fits your project

Your routeFirst reading and actionWhere the routes meet
Develop the scent yourselfChapters 2–6: equipment, materials, evaluation, accords and candidate selectionChapter 7 for bench preparation; Chapters 9–11 for packaging, assessment and launch preparation
Commission an external scentChapter 8: brief, scope, samples and responsibilities; use Chapter 4 for structured sample evaluationChapters 9–11, with the manufacturer's agreed technical responsibilities
Develop yourself and outsource productionChapters 2–6, with an early feasibility discussion using Chapter 8Transfer an identified candidate, then coordinate Chapters 7, 9 and 10 with the partner

Chapter 7 extends the bench-development exercise. Planning a commercial batch also requires the packaging decisions in Chapter 9 and the evidence plan in Chapter 10. Read those chapters before committing production quantities. Testing uses the specified product and representative packaging; unresolved results can send you back to formula or pack development.

Your next step

Complete this short decision record:

QuestionYour answer
What parts of perfumery do I want to learn personally?
Who will develop the first formula?
Which production tasks do I expect to outsource?
How much can I commit to the first learning or sampling stage?
What information do I need before making the next purchase or enquiry?

Choose a route for your first development stage. You can revisit it as your skills and project become clearer. The immediate aim is to know whether your next action is preparing a small learning workspace or writing a brief for an external partner.


2. Build Your First Perfumery Workspace

A useful first workspace allows you to weigh accurately, handle materials carefully and find the records for every sample. Buy equipment around these tasks. A collection of impressive tools does little to improve a trial if its ingredients were misidentified or its weights were not recorded.

This chapter covers a small learning setup. Detailed arrangements for commercial manufacturing, cleaning procedures and production areas follow in the manufacturing and compliance chapters.

2.1 Choose the balance first

Use a balance displaying grams to three decimal places: 0.001 g. Check its repeatability, linearity, capacity and adjustment procedure as well as its display. Readability is the smallest displayed increment; it does not establish how accurately you can weigh that amount.

A 0.001 g display therefore does not make a 0.001 g addition dependable. When a formula requires an amount too small for your equipment, prepare a suitable dilution or increase the trial size. Choose the approach before beginning the trial.

Two manufacturer's examples illustrate the difference:

SpecificationKERN TGD 50-3CKERN 440-21A
Capacity50 g60 g
Readability0.001 g0.001 g
Stated reproducibility0.003 g0.001 g
Stated linearity±0.003 g±0.003 g
Listed price, excluding VAT and shipping€69€380

Prices and specifications checked on 14 September 2026. These illustrate entry-level and laboratory options, not guaranteed performance in your workspace. The manufacturer's direct shop is B2B; individual buyers should check a suitable retailer. Sources: KERN TGD, KERN 440.

Capacity includes the vessel. Taring a heavy bottle resets the displayed net weight but does not recover the capacity occupied by that bottle. Check vessel dimensions against the pan and draft shield before purchasing. In particular, the 50 g preparation in Chapter 7 cannot be weighed in one vessel on a 50 g-capacity balance. Even a 60 g model requires a vessel light enough to keep the combined load within its limit.

Follow the manufacturer's warm-up and adjustment instructions. Use the specified check or adjustment weight and record checks. Place the balance on a level, rigid surface away from vibration and direct draughts. A simple repeated-weighing check can reveal unstable readings; it does not establish a validated minimum sample weight.

2.2 Two equipment shopping lists

The quantities below are editorial suggestions for a small learning collection. Adapt them to the supplier's pack sizes and your storage space. Prepare dilutions in stages: a bottle for a purchased material, a screening dilution, a formulation stock and a finished trial are separate containers. Thirty bottles do not hold all 30 materials at every stage simultaneously.

ItemEssential learning setupCommitted learning setup
BalanceEntry-level 0.001 g model with documented specificationsLaboratory 0.001 g model with better repeatability and service support
Check weightAppropriate weight specified for the balanceAppropriate weight, with a documented checking routine
Sample bottlesAbout 30 small glass bottles with compatible screw closuresAbout 60 bottles in consistent sizes, plus spare closures
Larger mixing vesselsTwo small borosilicate beakers and a few mixing bottlesSeveral vessel sizes selected to fit the balance
Transfer toolsDisposable pipettes, small spatulas and weighing boatsLarger supply of the same, organised to prevent mix-ups

ProtectionEye protection, suitable gloves and protective clothingSame protection, with replacements readily available
OrganisationWashable tray and secure storage appropriate to the materialsSeparate storage sections for stock, dilutions and trials
RecordsAccess to Scent Inventory during preparationSame, with a consistent recording and review routine

Ask for local prices for accessories, shipping and tax before setting a total budget. The verified balance prices above are the priced anchors for these two lists; this draft does not claim a verified total basket price. Materials and alcohol are additional purchases.

Prioritise the balance, secure closures and clear identification. Add equipment when a specific task calls for it. Filling machines and crimping equipment belong to a later production decision.

2.3 Handle and store materials deliberately

Work on a clean, washable surface in a suitably ventilated area, separate from food preparation. Keep children and animals away from the materials. Use dedicated utensils and follow each product's safety data sheet for handling, protection and storage.

Ethanol is highly flammable. Keep it away from ignition sources, close containers promptly and use only small working quantities. Do not heat alcoholic solutions on household equipment or keep flammable materials in an ordinary domestic refrigerator. Select storage and ventilation for the actual products and quantities being handled. An ethanol SDS illustrates the hazards; the SDS supplied with your alcohol governs that product's handling.

Read the spill, first-aid and disposal information before opening a material. Keep contaminated waste contained and dispose of it according to the product instructions and local arrangements. Avoid pouring fragrance residues into drains.

Separate unopened stock, working dilutions and trial samples. Keep heavily scented used strips away from fresh ones. Close and put away one stock bottle before opening the next; this simple habit reduces swapped caps, contamination and weighing errors.

2.4 Register materials as they arrive

In Scent Inventory, record the exact product name, supplier, supplied concentration, solvent where stated, batch identification and quantity received. Attach the documents available for that product. Record an opening date and retain the supplier's storage guidance.

A generic molecule name and a purchased product are related but not always interchangeable records. A diluted product, an isomer mixture or a particular natural extract needs its own identity. Record missing information as unknown rather than completing it from a similarly named product.

Use the actual mass consumed when updating stock. If a trial uses 0.500 g of a 10% solution, it consumes 0.500 g from the solution bottle. Its equivalent undiluted-material content is 0.050 g. Those figures describe different things.

When preparing a working stock, record the source material consumed and the solution produced. Later use consumes stock from that solution bottle. Expanding its ingredients for a formula calculation does not mean deducting the original material again. Apply the same principle to an accord made from several stocks.

Before your first session

Check that your balance is ready, your vessels fit its capacity, your materials are labelled and your handling information is accessible. Prepare the record and sample label before starting. You should be able to identify a bottle without relying on its position on the bench.

3. The 30-Material Starter Palette

Equipment for Your Starter Palette

Before exploring the 30 materials, prepare a small workspace for weighing, storing, smelling and identifying your samples. Start with the essentials and add equipment as your work develops.

Clear identification matters from your first session; handwritten labels can provide a practical starting point. Check label dimensions, durability and any printer compatibility before ordering. Compatibility between the linked label maker and labels has not been established.

In Scent Inventory, connect each bottle identifier to the exact material, supplied concentration, solvent, preparation date and evaluation notes.

Add Sample and Perfume Packaging Later

Begin the dilution and accord exercises with suitable screw-capped stock bottles and blotters. Introduce atomizers when you reach finished-perfume and packaging development.

Evaluate the actual perfume with the selected bottle, closure and pump. Check leakage, spray performance, fitting requirements and material compatibility. Follow Chapter 10 before supplying commercial samples, including free promotional samples.

Complete your workspace with the suitable perfumery alcohol, mixing vessels, check weight, protective equipment and storage arrangements described in Chapter 2. You can then begin learning the palette through small, clearly recorded trials.

A focused palette makes comparison manageable. The purpose of these 30 materials is to provide recognisable contrasts and reusable building blocks for several exercises. You will not need all 30 in every formula.

Fourteen materials from the core group form the two teaching accords and the complete worked candidate: Nos. 1–4, 6, 10–17 and 20. The other six core materials provide comparisons in citrus, fresh florals, jasmine and green effects. Nos. 21–30 broaden the studies to sweetness, powder, additional florals and contrasting base notes. A broad learning palette and the ingredient list of one perfume have different purposes.

The following groupings are navigation aids. Learn what you actually perceive on the strip and in mixtures. Odour descriptions are starting references, not answers you must reproduce word for word.

3.1 The first 20 materials

These are the original core materials, with stable numbers retained for purchasing and exercises.

No.MaterialStarting reference and learning purpose
1Iso E Supersmooth, woody, amber; compare abstract wood with cedarwood oil
2Hedione, standard gradelight, jasmine-like; investigate its contribution in a mixture

4Bergamot FCF oilcitrus, floral, green; a bridge between freshness and florals
5Sweet orange oilsweet, citrus, juicy; compare with bergamot
6Petitgrain bigarade oilgreen, bitter, woody; explore citrus leaves rather than fruit peel
7Linaloolfloral, fresh, lightly woody; a versatile comparison reference
8Ethyl linaloolfresh, floral; compare a related material with linalool
9Linalyl acetatebergamot-like, lavender-like, fresh; compare an ester with the alcohols
10Phenyl ethyl alcoholrosy, soft; build the body of a simple rose
11Citronellolrosy, fresh, citrus-like; compare rose alcohols
12Geraniolrosy, bright, lemon-like; explore a more assertive rose facet
13Nerolrosy, fresh, green; compare directly with geraniol
14Rose oxidegreen, metallic, rosy; learn the effect of a small accent
15Sandalorewarm, sweet, sandalwood-like; contrast with dry woods

19cis-3-Hexenolgreen, grassy, leafy; learn controlled green additions
20Ethylene brassylatemusky, soft; evaluate one musk and its effect in a mixture

The character of Iso E Super and Sandalore is documented by their manufacturers: IFF, Givaudan. The remaining traditional odour references draw on Calkin and Jellinek and Arctander, listed at the end of this chapter. Exact commercial qualities can differ.

Choose one standard Hedione quality for the exercises. Hedione HC has a different isomer balance and greater strength according to its manufacturer; treat it as a later comparison rather than silently substituting it. dsm-firmenich

3.2 Ten additional learning materials

No.MaterialStarting reference and learning purpose
21Vanillinsweet, vanilla-like, powdery; a clear reference for vanilla character
22Coumarinhay-like, tonka-like, sweet; compare sweetness with a dry facet
23Heliotropin / piperonalalmond-like, powdery, floral; explore soft floral sweetness
24Ethyl maltolsweet, caramel-like; explore sugar-associated odour
25Benzoin Siam resinoidbalsamic, sweet, vanilla-like; compare a resin extract with vanillin
26Hydroxycitronellalfloral, muguet-like, fresh; expand the floral vocabulary
27Alpha iononeviolet-like, woody, fruity; connect florals and woods
28Dihydromyrcenolfresh, citrus-like, lavender-like; compare freshness with citrus oils
29Patchouli oilearthy, woody; add a contrasting natural base material
30Aldehyde C-12 MNAaldehydic, dry, conifer-like; practise handling a strong accent

Alpha ionone is a distinct material, not methyl ionone. Specify alpha ionone, CAS 127-41-3, and record the supplied grade. Supplier descriptions support its violet, woody and fruity facets. Ethyl maltol is described as sweet and caramel-like. Alpha ionone, Ethyl maltol

Aldehyde C-12 MNA is also distinct from C-12 Lauric. Heliotropin is not automatically interchangeable with products sold as heliotrope bases or replacements. If a listed material is unavailable, mark the relevant exercise as deferred until a named alternative has been evaluated.

These ten additions broaden the palette without adding more musk varieties. Vanillin introduces a useful sweet reference; you can compare ethyl vanillin later. Sweet materials can also alter the balance of a floral or woody mixture without becoming its central theme.

3.3 Buy the right product, in a useful quantity

Choose small packs while learning. As an editorial starting point, look at approximately 5–10 g packs for many materials and smaller quantities or ready-made dilutions for powerful accents. These are purchasing suggestions, not required batch sizes. Check the actual pack sizes, stock concentrations and planned exercises before ordering. Ready-made low-strength solutions may suit smelling exercises but leave too much carrier for the stronger preparation in Chapter 7; check that recipe before selecting the supplied form.

For natural materials, retain the botanical identification, origin and extraction information where supplied. FCF identifies a treated bergamot quality; it is not a general declaration of unrestricted use. For resinoids, note any solvent and the supplied concentration. DirectPCW's Benzoin Siam listing is an example of why the specific commercial extract should be recorded.

Perfumery suppliers to investigate include DirectPCW, De Hekserij and The Perfumer's Apprentice. Compare the actual products and shipping terms. Inclusion here does not verify that one supplier stocks all 30 materials, delivers alcohol to your country or provides every document needed for commercial use.

A small-quantity buyer may not have access to every technical document. Save what is provided, identify the gaps and recognise that a material used for learning may later need additional supporting information or replacement before commercial development can proceed. Chapter 10 explains that transition.

The 10 g dilution examples are calculation exercises, not a fixed quantity to prepare for every material. Before the accord work, list the stocks each planned trial will consume and allow for evaluation strips, retained references, repeat preparation and handling losses. The two complete reference accords will each be needed in more than a single 10 g batch if you carry out all variations and complete-fragrance comparisons.

3.4 Choose perfumery alcohol deliberately

Purchase ethanol or a prepared alcohol product explicitly suitable for the intended perfumery use. The term “perfumer's alcohol” does not describe one universal composition: products can contain different denaturants or other ingredients. Ask what you are buying and retain the product documentation. De Hekserij's explanation describes this variability.

Record the stated ethanol strength and whether it is expressed by mass or volume. Do not interpret 96% v/v as 96% w/w. For the mass-based exercises in this guide, the alcohol product is weighed as the solvent as supplied; its own water or additive content remains part of that product.

Avoid household methylated spirits, cleaning alcohol and beverages as unverified substitutes. Alcohol availability, denaturing arrangements and transport conditions depend on location and supplier. Confirm delivery before buying the rest of the equipment around an unavailable solvent.

Evaluate a solvent-only blotter alongside a new dilution. A persistent solvent odour can interfere with what you learn. A suitable solvent must also dissolve the material at the intended concentration; the clearest-smelling choice is of little use if crystals remain in the bottle.

3.5 Your material record

For each purchase, keep the exact identity and supplied concentration separate from your sensory notes. In Scent Inventory, attach the available data sheets and use your notes for dated observations, including the test dilution and solvent.

The goal at this stage is a collection you can identify and learn from. Before blending accords, select a few contrasting materials and complete the evaluation routine in Chapter 4.
