Phenoxyethanol (Phenoxyethanol)

Phenoxyethanol is a widely used preservative in cosmetic formulations, valued for its broad compatibility and reliable support against microbial growth when incorporated into well-designed preservation systems. Effective primarily against many bacteria (with complementary coverage typically achieved through co-preservatives), it helps protect product integrity, extend shelf life, and maintain overall safety throughout use. Phenoxyethanol is commonly found in emulsions, serums, toners, cleansers, masks, sunscreens, and haircare products, performing well across a range of textures and formats. It is frequently paired with organic acids, glycols, or multifunctional boosters to enhance spectrum performance and improve robustness under real-world conditions. Formulation considerations include the target pH range, solubility and phase placement, potential odor contribution, and compatibility with packaging and other raw materials. Recommended use levels and regulatory suitability depend on product type and region and should be confirmed against applicable cosmetic regulations and supplier specifications.
