Heptyl Unedecylenate ●
TL;DR. This ingredient is a lightweight emollient and slip agent that gives creams, oils, sunscreens, and color cosmetics a dry, fast-spreading feel. It is also used as a non-silicone sensory modifier and pigment-dispersion aid.
What does Heptyl Unedecylenate do in a cosmetic formula?
This ingredient is a lightweight emollient and slip agent that gives creams, oils, sunscreens, and color cosmetics a dry, fast-spreading feel. It is also used as a non-silicone sensory modifier and pigment-dispersion aid.
Is Heptyl Unedecylenate clean?
From a clean-beauty perspective, it is generally well tolerated, not a common allergen, and has no broad restricted-list profile. Clean frameworks typically view it favorably when supplier documentation supports natural-origin sourcing and low residual impurities.
Is Heptyl Unedecylenate sustainable?
This material is commonly offered from renewable oleochemical feedstocks, often linked to castor-derived fatty acid chemistry. It is readily biodegradable and does not raise the persistence concerns associated with many silicone fluids.
Is Heptyl Unedecylenate COSMOS-approved?
It is permitted under COSMOS-natural and can fit COSMOS-organic formulas when the supplier confirms compliant feedstocks and processing. It aligns well with Green Chemistry principles through renewable sourcing, esterification-based manufacture, and good biodegradability.
How does Heptyl Unedecylenate work chemically?
The molecule is a C18 mono-unsaturated fatty ester, combining a C7 alkyl chain with an 11-carbon chain containing a terminal double bond, which gives low polarity and a light, dry sensory profile. It is typically used around 1 to 20% as an emollient, is most stable in mildly acidic to neutral systems, and may benefit from standard antioxidant support because it contains one unsaturated bond.
