Overview

Ethylhexylglycerin is a common component of preservative ingredients. Derived from glycerin, ethylhexylglycerin functions by creating a bacteriostatic environment, or one in which bacteria cannot grow effectively. It is frequently used as a preservative booster and pairs well with ingredients like phenoxyethanol and caprylyl glycol.

In addition to working as a preservative, ethylhexylglycerin is also a humectant. Due to its chemical base of glycerin, it attracts water to the surface of the skin, creating a moisturizing effect. Its molecular structure also contains a short carbon chain, which can cause this ingredient to act as an emollient oil, as well.
