undecenol ●
TL;DR. This ingredient is primarily used as a fragrance component and odor modifier, adding fatty, waxy, green, or citrus-like nuances at very low levels. It may also support masking of base odors in a finished formula.
What does undecenol do in a cosmetic formula?
This ingredient is primarily used as a fragrance component and odor modifier, adding fatty, waxy, green, or citrus-like nuances at very low levels. It may also support masking of base odors in a finished formula.
Is undecenol clean?
From a clean-beauty perspective, this ingredient sits in the fragrance category, where acceptability depends on disclosure, concentration, and sensitization screening. It is not a broad restricted-list red flag, but its aroma-chemical role gives it more review friction than bland functional ingredients.
Is undecenol sustainable?
This material can be made from petrochemical routes or from renewable fatty feedstocks, including castor-derived chemistry, so sourcing matters. As a small fatty alcohol, it is expected to be biodegradable, but its sustainability profile is strongest when renewable origin and responsible processing are documented.
Is undecenol COSMOS-approved?
It may align with COSMOS only when it is natural or derived from allowed natural-origin feedstocks and used in a compliant fragrance system. From a Green Chemistry view, renewable sourcing and biodegradability are positives, while synthetic fragrance use and oxidation-management needs keep it from being a simple green signal.
How does undecenol work chemically?
The molecule is an 11-carbon monounsaturated primary fatty alcohol, combining a polar alcohol head with a hydrophobic unsaturated chain. It is oil-soluble, poorly water-soluble, and the double bond can slowly oxidize with air, light, or heat, so antioxidant support and tight packaging can help preserve odor stability.
