What it does: Phenoxyethanol interferes with the cell walls of bacteria, yeast, and mold, effectively helping to inhibit their growth and reduce the risk of spoilage or contamination in products.
How it is used: This compound is most commonly utilized in supplements, topical creams, lotions, serums, and other formulations that have high moisture content or are prone to microbial growth, supporting longer shelf stability.
Natural sources and supplement forms: While very small amounts may occur naturally in green tea, almost all phenoxyethanol used in supplements and cosmetics is produced synthetically to ensure purity and consistent quality.
Why it appears in supplement formulas: It is valued for its broad-spectrum antimicrobial protection and is selected to reliably guard against microbial contamination where other preservation methods may be inadequate.
What to know before use: Phenoxyethanol is generally well tolerated at low concentrations, though minor skin irritation or sensitivity is possible for some individuals, especially with direct skin contact.
Phenoxyethanol: A Common Preservative from Green Tea
Phenoxyethanol is widely used as a preservative in both supplements and cosmetics to help maintain product freshness by preventing the growth of bacteria and mold. Interestingly, while it is often produced synthetically, phenoxyethanol also occurs naturally in green tea, making it a unique ingredient that bridges natural and lab-made sources.
