Short profile
The principal description presents a pronounced floral-green character illuminated by an aldehydic accent. Cool greenery contrasts with sweet anthranilate nuances, including a subtle grape suggestion, while broom, orange blossom and muguet define the floral range. Development is described as gradual, requiring several hours of evaluation rather than an immediate judgement. The page does not establish a distinct opening-to-dry-down sequence or projection profile; its separate amber-woody laboratory description conflicts with the principal floral-green account.
Effect in a formula
Adds a bright aldehydic-green dimension to floral structures, with a sweet broom inflection and gradual development. Suitable themes include mimosa, gardenia, honeysuckle and broom, while citrus compositions can use its peel emphasis. The supplier also recommends it for functional fragrance applications on stability grounds.
Use and dosage
The main product description gives a customary concentrate dosage of 0.5–5%, alongside recommendations for floral compositions, citrus-peel themes and functional fragrances. This is formulation guidance, not an IFRA limit. A separate, inconsistent amber-woody section gives 0.1–3% for finished fragrance; that figure should not be treated as an alternative concentrate range.
No confirmed manufacturer use level for this exact product.
Behaviour and performance
- Tenacity
- The supplier's TGSC-attributed data report 400 hours of blotter substantivity, without specifying dilution or test conditions. Elsewhere the page characterises persistence as medium and measured in hours, so its longevity reporting is internally inconsistent.
Diffusion, tenacity and note impact are not combined into a single performance score.
Dissolving and diluting
- Solvents
- Ethanol, DPG and IPM are listed as solvents, with prompt formation of clear solutions reported. No concentration-dependent solubility data are supplied. This information occurs in the laboratory section whose odour and chemical-family description conflicts with the main entry.
- Working dilution
- The dilution panel lists a 10% working solution, with ethanol selected in the linked calculator, and suggests 1% for olfactory assessment. These instructions accompany an amber-woody description that is inconsistent with the main product account.
- Appearance
- Listed as a liquid ranging from colourless to a light yellow tint. The appearance statement is repeated in the dilution panel, although the associated laboratory description is inconsistent with the main product account.
