Usage
Used in cosmetics, pharmaceuticals and food industries as a broad-spectrum preservative and antimicrobial agent, effective against Gram-positive and Gram-negative bacteria, molds and yeasts. Widely used in creams, lotions, shampoos, cleansers and topical preparations to extend shelf life and maintain storage stability. Propylparaben has higher antimicrobial activity than methyl and ethyl parabens, and is often combined with other parabens for synergistic preservation. Recommended dosage: 0.2%–0.5%, applicable pH range 4–8.
