Octyldodecyl PCA ●
TL;DR. This ingredient is primarily an emollient and skin-conditioning agent, adding a soft, cushiony feel while helping reduce moisture loss from the skin surface.
What does Octyldodecyl PCA do in a cosmetic formula?
This ingredient is primarily an emollient and skin-conditioning agent, adding a soft, cushiony feel while helping reduce moisture loss from the skin surface.
Is Octyldodecyl PCA clean?
From a clean-beauty perspective, it is generally well tolerated and does not sit on common restricted lists. The main watchpoint is feedstock transparency, since natural-origin and synthetic grades can both exist.
Is Octyldodecyl PCA sustainable?
This material is typically made by esterifying a fatty alcohol with a moisture-factor-derived acid, with sourcing that may be plant-based or synthetic depending on the supplier. It is expected to be biodegradable as an ester, and its sustainability profile improves when the fatty component is renewable and traceable.
Is Octyldodecyl PCA COSMOS-approved?
It can be permitted under COSMOS-natural when made from approved natural-origin feedstocks using allowed esterification chemistry, while fully synthetic grades may not qualify. Its Green Chemistry fit is strong when renewable inputs, efficient esterification, and good biodegradability are documented.
How does Octyldodecyl PCA work chemically?
The molecule is a branched C20 alkyl ester of a five-membered lactam carboxylate, combining a lipophilic tail with a polar head group for emollience plus a light moisturizing effect. It is usually used in the oil phase at low single-digit percentages, is most stable in mildly acidic to neutral systems, and can hydrolyze under strongly acidic or alkaline conditions.
