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 mold, extending shelf life. Commonly found in creams, lotions, shampoos, and liquid medications where long-term stability is required. Its effectiveness at low concentrations makes it a preferred choice in formulations requiring minimal additive levels. Also used in combination with other parabens to enhance broad-spectrum preservation.
