Glyceryl Undecylenate

Other names: Glyceryl Monoundecylate, Undecylenic acid

Glyceryl Undecylenate, also known as Glyceryl Monoundecylate or Undecylenic acid, is an ester of undecylenic acid and glycerol. It is a non-ionic emulsifier and stabilizer that is naturally derived from oleic acid, found, for example, in saturated fats. This substance is widely used in the cosmetic industry for its emulsifying properties, which means the ability to combine water and oil molecules into a stable mixture.

Glyceryl Undecylenate is thus commonly found in a wide range of cosmetic and personal care products such as creams, soaps, shampoos, lip balms, make-up and other skin care products. It is often included in products for sensitive skin because it helps soothe irritation and inflammation while moisturizing the skin. Because it is relatively mild and non-aggressive, it is also suitable for children's skin care. In addition, due to its antimicrobial activity, it is also used in products designed to treat fungal infections, such as antifungal creams and sprays. It is also used in bio-plastics as a plasticizer.
