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 lotions, creams, shampoos, and liquid medications where long-term stability is required. Its effectiveness over a wide pH range and low toxicity make it a preferred choice in many formulations. Often used in combination with other parabens to enhance preservation spectrum.
