Phenoxyethanol (and) Ethylhexylglycerin

This is a synergistic preservative blend where phenoxyethanol (typically 0.9-1.0%) serves as the primary broad-spectrum antimicrobial agent while ethylhexylglycerin (typically 0.1-0.3%) acts as a preservative booster and skin conditioning agent. The combination allows for lower usage levels of phenoxyethanol than would be needed alone, while ethylhexylglycerin enhances the preservative's efficacy by disrupting microbial cell membranes and simultaneously provides a soft, silky skin feel. Formulators favor this blend for its excellent broad-spectrum protection, global regulatory acceptance, and the dual benefit of preservation plus sensory enhancement in leave-on and rinse-off products.
