Isoraldeine 70 (Givaudan®)

Iris and violet define the floral character, supported by a dry, powdery woodiness. A leathery shading gives this grade a more robust profile than Isoraldeine 95, while a gentle fruity sweetness softens the overall impression. Its reported odour strength is moderate, but it remains perceptible within dense compositions. Several hours into blotter evaluation, the persistent woody aspect becomes particularly apparent; the supplier does not describe a separate opening phase.

Provides a persistent powdery framework that connects floral components with woody notes. Its dry iris-violet character retains definition against substantial leather, wood and resin backgrounds. Suitable applications include fougères, chypres and leather compositions, as well as powder-focused florals.

The supplier recommends 1–20% of the fragrance formula for developing an iris-violet framework with powdery and woody emphasis, particularly in fougère, chypre and leather work. A separate laboratory section gives 1–15% in the finished fragrance; that figure should not be treated as an additional concentrate range. These are formulation recommendations, not IFRA limits.

No confirmed manufacturer use level for this exact product.

Tenacity

The page reports 184 hours of blotter substantivity, citing TGSC as its data source. The test concentration and environmental conditions are not specified. Its practical evaluation notes also describe a woody character persisting after several hours on a strip.

Diffusion, tenacity and note impact are not combined into a single performance score.

Solvents

Ethanol, DPG and IPM are reported to dissolve the material readily, producing clear solutions.

Working dilution

Evaluate at 10% in ethanol. For compounding, the supplier lists either undiluted material or a 10% working solution; DPG and IPM are also listed as suitable solvents.

Appearance

Liquid ranging from colourless to pale yellow.
