🔬 Description
Hydrogen Peroxide – Powerful Antimicrobial & Oxidizing Agent for Cosmetic and Cleaning Formulas
Hydrogen Peroxide (H₂O₂) is a potent oxidizing agent widely used in personal care, disinfection, and cosmetic processing. At cosmetic-grade concentrations (typically 3% to 6%), it’s used for hair bleaching, acne control, skin lightening, and as a mild antiseptic. It works by releasing oxygen when it comes in contact with skin or other surfaces, effectively killing bacteria and breaking down pigments or organic matter. In higher concentrations, it is used in technical cleaning and formulation processes. It must always be handled with caution due to its oxidative nature.
