Decylene Glycol
What is Decylene Glycol?
Decylene glycol, or 1,2-decanediol, is a synthetic aliphatic diol with a 10-carbon chain, produced through hydrogenation of 1,2-epoxydecane. In cosmetics, it functions mainly as a humectant, skin conditioning agent, and preservative booster. By attracting and binding water molecules, it supports skin barrier hydration and imparts a smooth, supple feel. Its amphiphilic nature enables it to integrate into emulsions, enhancing spreadability and stability. Additionally, it exhibits broad-spectrum antimicrobial activity by altering bacterial cell permeability, making it useful in deodorants and cleansers. Typically incorporated at low levels in leave-on products like creams, lotions, and serums, it offers a milder alternative to traditional preservatives while contributing to emollience without greasiness.
