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 medications where long-term stability is required. Its low toxicity and high stability over a range of pH and temperatures make it ideal for use in products that require sterile conditions. Often combined with other parabens to enhance preservation efficacy.
