Phenoxyethanol and Caprylyl Glycol Preservative Blend

Origin

Phenoxyethanol in Caprylyl Glycol is a broad-spectrum preservative blend composed of Phenoxyethanol (synthetic aromatic ether alcohol) and Caprylyl Glycol (naturally derived diol). This synergistic system combines effective antimicrobial protection with skin-conditioning and humectant properties. The blend is designed for formulators seeking paraben-free and formaldehyde-free preservation systems, commonly derived from petrochemical (Phenoxyethanol) and coconut/palm kernel oil (Caprylyl Glycol) sources.

Summary

This preservative blend provides robust, broad-spectrum antimicrobial efficacy against bacteria, yeast, and mold while offering skin-conditioning and emollient benefits. It functions as both a preservative and multifunctional additive, helping to improve the feel, stability, and safety of cosmetic and personal care products. Phenoxyethanol ensures strong preservation, while Caprylyl Glycol enhances efficacy through microbial membrane disruption and moisturization. Together, they form a gentle yet effective system suitable for a wide range of leave-on and rinse-off formulations.
