Cosmetic, Pharmaceutical & Industrial Grade Phthalimidoperoxycaproic Acid (PAP) CAS 128275-31-0 Peroxy Acid Bleaching Agent for Teeth Whitening & Disi

Phthalimidoperoxycaproic Acid (PAP, CAS:128275-31-0,EINECS:410-850-8, HS Code:2925199090) is a white odorless crystalline organic peracid compound with molecular formula C₁₄H₁₅NO₅ and molecular weight 277.27. We supply industrial and cosmetic grades meeting international quality standards. Unlike traditional peroxides, PAP acts via non-radical oxygen transfer, enabling effective bleaching and disinfection under mild pH (6-8) and low temperature (15-40°C) conditions without activators. It offers superior stability in formulations, making it ideal for pre-mixed shelf-stable products.

Applications
Laundry & Textile Industry
Excellent bleaching agent for detergents, removing stubborn stains (tea, coffee, grass, tomato) at low temperatures without damaging fabrics. Preserves fiber integrity and color fastness while eliminating odors and bacteria. Ideal for eco-friendly and high-efficiency detergent formulations.
Oral Care & Cosmetics
Premium teeth whitening ingredient in toothpastes, gels and strips. Non-irritating to oral mucosa, preserves enamel microhardness without erosion, and prevents tooth sensitivity. Also used as disinfectant and brightening agent in personal care products.
Hard Surface Disinfection
Effective sanitizer for household, institutional and industrial surfaces. Kills bacteria, fungi and viruses without harsh residues, safe for food contact surfaces. Works in neutral pH range, compatible with most cleaning formulations.
Other Industrial Applications
Used as oxidizing agent in organic synthesis, particularly for selective epoxidation reactions. Also applied in water treatment, paper bleaching and specialty chemical manufacturing.
