Description
A synthetic preservative that prevents harmful bacteria, mold, and yeast from growing in cosmetic products, helping to extend shelf life and maintain product safety. It's commonly used in skincare formulations because it works effectively at low concentrations and has broad-spectrum antimicrobial activity. Some individuals may experience sensitivity or irritation, so patch testing is recommended for those with reactive skin.
