Used as a preservative in cosmetics, pharmaceuticals, food products, and personal care items due to its antimicrobial properties. It effectively inhibits the growth of bacteria, yeast, and mold, extending shelf life. Commonly found in creams, lotions, shampoos, soaps, and liquid medications where long-term stability is required. Its ester structure enhances lipid solubility, allowing better integration into formulations without affecting product clarity or odor. It works well across a wide pH range and is often combined with other preservatives, such as different parabens, for broad-spectrum protection.
