Sodium Benzoate

Sodium Benzoate is a widely trusted, gentle preservative that helps keep cosmetic products fresh, effective, and safe for longer periods. It primarily protects formulas from the growth of fungi, yeast, and certain bacteria—ensuring lotions, gels, toners, cleansers, and baby-care products maintain their quality throughout their shelf life. Because it works best in mildly acidic environments (pH 3–5), it is ideal for modern formulations like vitamin C serums, exfoliating products, fruit-based gels, and natural skincare where maintaining low pH is essential.
Although mild, Sodium Benzoate becomes highly effective when paired with co-preservatives like Potassium Sorbate, creating a balanced preservation system suitable for clean-label, sensitive-skin, and eco-conscious formulations. Its safety profile, global regulatory acceptance, and compatibility with natural and organic cosmetic standards make it a preferred choice in premium skincare, personal hygiene products, and kids’ products—offering reliable protection while supporting gentle, skin-friendly formulations.
