Saliethanol is a glycol ether produced through the reaction of ethanol with phenolic groups and is widely used as a preservative in cosmetic formulations. It exhibits broad-spectrum antimicrobial activity against both Gram-positive and Gram-negative microorganisms, helping to prevent or reduce bacterial contamination. Saliethanol is approved for global cosmetic use at concentrations of up to 1%, primarily to control microbial growth and maintain product stability.
