Heptyl Undecylenate ●
TL;DR. This ingredient is a lightweight emollient ester used to improve slip, spreadability, and a dry-touch skin feel in creams, sunscreens, color cosmetics, and hair products. It can also help disperse pigments and UV filters in anhydrous or emulsion systems.
What does Heptyl Undecylenate do in a cosmetic formula?
This ingredient is a lightweight emollient ester used to improve slip, spreadability, and a dry-touch skin feel in creams, sunscreens, color cosmetics, and hair products. It can also help disperse pigments and UV filters in anhydrous or emulsion systems.
Is Heptyl Undecylenate clean?
This ingredient is generally well tolerated and has a low irritation profile in typical cosmetic use. It is commonly accepted in clean-beauty frameworks because it is biodegradable, non-silicone, and not a common restricted-list concern.
Is Heptyl Undecylenate sustainable?
This material is typically made from renewable plant-derived fatty chemistry rather than petrochemical silicone chemistry. It is expected to biodegrade readily, and its main sustainability questions are feedstock traceability and agricultural sourcing practices.
Is Heptyl Undecylenate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when sourced and processed according to the standard’s rules for chemically processed agro-ingredients. From a Green Chemistry view, it aligns well through renewable feedstocks, efficient ester chemistry, and good biodegradability.
How does Heptyl Undecylenate work chemically?
The molecule is a C18 mono-unsaturated ester with low polarity, which gives fast spreading, cushion, and a dry emollient finish. Typical use levels are often around 1 to 20 percent, and it is broadly stable in cosmetic emulsions but can slowly hydrolyze under very acidic or very alkaline conditions.
