Cosmetic Grade Trisodium Phosphate-CAS 7601-54-9
Cosmetic-grade Trisodium Phosphate (TSP) is a high-purity inorganic phosphate functional auxiliary specially refined for cosmetic and daily chemical formulas. It integrates multiple core functions such as alkaline pH regulation, metal chelation and water softening, and is an essential stabilizing and synergistic raw material for neutral and weakly alkaline daily chemical systems.
TSP has efficient pH adjustment and buffering capacity, which can accurately adjust and stabilize the alkaline pH value of cleaning products, optimize the foaming performance and cleaning power of surfactants, and improve the overall use experience of cleansing products.
Meanwhile, it can efficiently chelate calcium, magnesium, iron and other metal ions in production water and raw materials, eliminate hard water interference, solve common formula problems such as turbidity, flocculation and precipitation caused by hard water, and purify the cosmetic water system.
It can shield the catalytic oxidation of metal ions on active ingredients, effectively inhibit product yellowing and discoloration, and extend the shelf stability of finished products. In addition, Trisodium Phosphate has excellent decontamination synergistic effect, which can significantly enhance the decontamination and emulsifying capacity of cleansing formulas, making foam rich and delicate and rinsing more clean.
With high purity, low impurity and stable chemical properties, it has good compatibility with surfactants and various functional additives, does not affect the fragrance and basic texture of finished products, and is a cost-effective multi-functional auxiliary for daily chemical formula optimization and stability improvement.
