Phenoxyethanol (Phenoxyethanol) is a versatile preservative widely used in cosmetics and personal care products to ensure product longevity and safety. Known for its biocidal properties, it is particularly effective against Gram-negative bacteria and is often employed in combination with other preservatives due to its limited efficacy against yeast and mold. With a stability range reaching up to 85°C (185°F) and effective activity across a pH spectrum of 3 to 10, Phenoxyethanol adapts well to various formulation needs. This ingredient is not only soluble in most oils but also in water, in concentrations ranging from 0.5 to 2.67 grams per 100 grams. Additionally, it serves as a valuable solvent in the fragrance industry, lending its floral aroma while enhancing the solubility of parabens and other preservatives. For enhanced protection against yeast and mold, it is advisable to pair Phenoxyethanol with Potassium Sorbate, creating a robust preservation system.
