Used as a preservative in cosmetics, personal care products, and food due to its strong antimicrobial and antifungal properties. It prevents the growth of bacteria, yeast, and mold, extending shelf life. Commonly found in creams, lotions, shampoos, and liquid soaps where long-term preservation is required without altering the product’s appearance or scent. Also used in some industrial applications to protect water-based solutions from microbial contamination.
