BUTYLGLYCERIN.

Valuable

Butylglycerin is a versatile alkyl glyceryl ether that functions as a multi-tasking ingredient, providing hydration while enhancing the penetration of other actives. Its unique amphiphilic structure allows it to boost preservative efficacy against acne-causing bacteria, making it particularly valuable in targeted treatment formulations.

solvent humectant emollient antimicrobial booster

Science

Works through hydrogen bonding to attract and retain moisture in the skin while temporarily modifying stratum corneum lipid structure to enhance ingredient penetration. Additionally disrupts bacterial cell membranes, creating synergistic antimicrobial effects with traditional preservatives.
