Sodium Dehydroacetate Cosmetic Preservative（CAS 4418-26-2）
Cosmetic-grade Sodium Dehydroacetate is a high-purity, food-safe broad-spectrum preservative, which is one of the most mainstream mild antibacterial raw materials in the cosmetic and daily chemical industry. Different from traditional preservatives that are easy to decompose at high temperature, it has excellent high-temperature resistance, stable bacteriostatic activity even in high-temperature production processes above 100℃, and will not fail or decompose.
It has an ultra-wide antibacterial spectrum, which can effectively inhibit and kill gram-positive bacteria, gram-negative bacteria, molds and yeasts, thoroughly solving common deterioration problems such as product mildew, turbidity, odor and bacterial over-standard. With food-grade safety attributes, it is mild and non-irritating, no sensitization risk, and suitable for high-standard mild formula systems.
The product has stable chemical properties, no peculiar smell, pure color, wide pH adaptability, and excellent compatibility with various water-based and emulsified formulas. It does not affect the color, fragrance and skin feel of finished products, fully complies with domestic and international cosmetic safety regulations, and is the preferred high-stability preservative for high-temperature process formulas and sensitive mild skin care products.
