While p-anisic acid has antioxidant and anti-inflammatory properties, its primary use in cosmetics is a fragrance enhancer and gentle preservative. Its antimicrobial properties fight both bacterial and yeast contamination in cosmetics, enabling them to be safer, more effective, and last longer. Although not a known irritant or sensitizer, p-anisic acid should be considered with caution by those allergic to aniseed ingredients. Related ingredients: Preservatives
