p-Hydroxyacetophenone Cosmetic Grade-CAS 99-93-4
p-Hydroxyacetophenone is a high-purity green cosmetic preservative and functional raw material, which is a new generation of mild and safe antiseptic substitute for traditional preservatives. It has broad-spectrum bacteriostatic ability, effectively inhibiting the reproduction of bacteria and molds in cosmetic formulas, and significantly extending the shelf life of finished products.
Different from traditional preservatives such as parabens and phenoxyethanol, it features ultra-low irritation, high temperature resistance and strong stability, suitable for high-temperature formula production processes. In addition to antiseptic and bacteriostatic effects, it also has excellent antioxidant activity, which can effectively prevent formula oxidation, discoloration and deterioration, and stabilize active ingredients.
With wide pH adaptability (pH 3-8), it can be perfectly compatible with most cosmetic water-phase and emulsion systems. It does not contain alcohol, formaldehyde and harmful residues, fully complies with EU, FDA and domestic cosmetic safety standards, and is the preferred preservative for high-end mild, zero-addition and sensitive skin care formulas.
Key Benefits
• Broad-Spectrum Antiseptic & Bacteriostatic: Effectively inhibit bacteria, molds and yeasts, solve product mildew and deterioration problems, and extend shelf life stably.
• Ultra-Mild & Zero Irritation: Non-toxic and non-irritating, no skin sensitization reaction, safe for sensitive skin and infant care formulas.
• High Temperature Resistance & Stable Performance: Stable at high temperature, no decomposition or inactivation during heating and emulsification process, suitable for various production processes.
• Dual Antioxidant Stabilization: Inhibit formula oxidation and discoloration, protect active ingredients and improve formula stability.
• Wide pH Adaptability: Maintain efficient activity in pH 3-8 environment, compatible with acidic, neutral and weak alkaline formulas.
• Green & Safe Compliance: No formaldehyde, no alcohol, no harmful residues, fully compliant with global high-standard cosmetic regulations.
Applications
• Facial Skin Care Series: Applied in facial cleanser, toner, lotion, cream, essence and facial mask for mild antisepsis and stabilization.
• Sensitive & Infant Care: Used in sensitive skin care products, baby lotion and mild care formulas to replace irritating traditional preservatives.
• Color Cosmetic Products: Added into foundation, lipstick, eye shadow and liquid makeup to prevent mildew and oxidation deterioration.
• Body & Hair Care: Suitable for body wash, shampoo, conditioner and hand care products for long-term antisepsis and preservation.
• High-End Zero-Addition Formulas: Core preservative for high-end pure plant, organic and mild zero-addition cosmetic systems.
