Caprylyl Glycol (1,2-Octanediol)
CAS Number: 1117-86-8
Caprylyl Glycol (1,2-Octanediol) is a multifunctional glycol that acts as both a skin-conditioning emollient and a preservation enhancer. It demonstrates broad-spectrum antimicrobial activity on its own and synergizes strongly with phenoxyethanol and ethylhexylglycerin for robust preservation systems. Its moisturizing and skin-feel properties also add value to formulations beyond its preservation function.
