Widely used as a preservative in cosmetics, pharmaceuticals, and food products due to its effective antimicrobial properties. It prevents the growth of bacteria, yeast, and molds, extending shelf life. Commonly found in creams, lotions, shampoos, and liquid soaps where long-term preservation is essential. Also used in some oral and topical medications to maintain product integrity. Its stability across a range of pH levels and temperatures makes it suitable for various formulations. Often combined with other preservatives to enhance broad-spectrum protection.
