Boosting properties of ethylhexylglycerin in self-preserving systems

Cosmetic formulators are looking for ways to keep their products microbiologically stable without the use of traditional preservative systems. This includes a combination of possibilities to prevent micro-organisms from growing, e.g. modifying pH value or water activity of a formulation, using chelating agents or multifunctional materials, as well as looking for a suitable packaging.

Ethylhexylglycerin is an excellent booster for antimicrobial actives. A repeated challenge test has been performed to illustrate the use of ethylhexylglycerin to improve the efficacy of antimicrobials, such as glycols.
