Phenoxyethanol is a synthetic preservative that's used to help prevent microorganisms from growing in cosmetic formulas. At Origins, we use an amount of Phenoxyethanol that is recognized as safe—less than 1%—as needed to maintain product integrity as you use it; we do not over-preserve. We also continuously work to identify additional preservatives that are safe and effective for you and the planet. It's part of our ongoing commitment to your well-being.
