What it does: Phenoxyethanol works by disrupting the cell membranes of microbes, which helps prevent growth of bacteria, yeast, and molds that can spoil products or pose safety risks.
How it is used: It is most commonly found as a preservative in moisture-rich supplements, topical creams, cosmetics, and personal care products to extend shelf life and maintain product integrity.
Natural sources and supplement forms: Trace amounts occur naturally in green tea, but almost all forms used in supplements and cosmetics are synthetically made to ensure quality and consistency.
Why it appears in supplement formulas: It is selected to provide reliable, broad-spectrum antimicrobial protection that reduces the risk of spoilage or contamination in products that are susceptible to microbial growth.
What to know before use: Phenoxyethanol is generally safe at low levels, but some individuals may experience skin irritation or sensitivity, particularly with direct topical exposure.
