A functional emollient. Safe.
Glyceryl undecylenate (INCI: Glyceryl Undecylenate) is an ester of glycerin and undecylenic acid. It plays a dual functional role: it acts as an emollient that softens skin and as an agent with mild antimicrobial action that helps stabilize the formula. It is not a care active but a support and preservation component. Its usefulness lies in improving the product's feel and reinforcing stability against microbes, which can sometimes let a formula cut back on harsher preservatives. The effect on skin is the usual emollient one, with no treatment claims. Topically it has no systemic relevance, so it can be used during pregnancy and breastfeeding. Tolerance is good and the allergy potential is low. Its comedogenicity is very low (1 out of 5), so it also fits oily or acne-prone skin.
