Used primarily as a preservative in cosmetics and personal care products due to its antimicrobial properties. Effective against bacteria, yeast, and molds, it helps extend shelf life by preventing microbial growth. Commonly found in lotions, creams, shampoos, and makeup. Its ester structure provides better skin compatibility and reduced irritation compared to shorter-chain parabens. Often used in combination with other preservatives for broad-spectrum protection. Also shows stability across a wide pH range and in heat-processed formulations.
