Cosmetic Grade Tetrasodium Pyrophosphate-CAS 7722-88-5
Cosmetic-grade Tetrasodium Pyrophosphate (TSPP) is a high-purity inorganic pyrophosphate multifunctional stabilizer specially refined for daily chemical and cosmetic systems. With moderate alkalinity and stable chemical properties, it fills the performance gap between weak acid buffer agents and strong alkaline regulators, serving as a core auxiliary for neutral and weakly alkaline cleansing and skincare formulas.
TSPP features precise and mild alkaline pH adjustment, which can scientifically stabilize the pH value of surfactant systems, activate surfactant activity, optimize foaming fineness and persistence, and significantly improve the cleaning and emulsifying capacity of cleansing products.
It has excellent metal chelating and water softening effects, which can efficiently capture calcium, magnesium, iron and other metal impurities in water and raw materials, eliminate hard water interference, solve common formula problems such as turbidity, flocculation, precipitation and delamination, and purify aqueous cosmetic systems.
In addition, TSPP can shield metal ion catalytic oxidation, inhibit active ingredient failure and finished product yellowing and discoloration, effectively extending shelf stability. Different from strong alkaline regulators, it has mild regulation performance, will not cause excessive pH fluctuation, can stabilize formula viscosity and system uniformity for a long time, has excellent compatibility with various surfactants and functional additives, does not affect product fragrance and skin feel, and is a cost-effective universal stabilizing synergist for high-stability daily chemical formulas.
Key Benefits
• Mild & Precise Alkaline Regulation: Moderate alkalinity avoids excessive pH fluctuation, stably locks the weak alkaline pH of cleansing formulas, activates surfactant activity and optimizes foaming performance.
• High-Efficiency Chelation & Water Softening: Quickly captures calcium, magnesium and iron metal ions, eliminates hard water interference, fundamentally solves formula turbidity and precipitation, and purifies the water system.
• Anti-Oxidation & Color Stabilization: Shields metal catalytic oxidation reactions, protects active ingredients from failure, prevents finished products from yellowing and discoloration, and maintains pure and transparent texture.
• Decontamination & Emulsification Synergy: Significantly enhances the decontamination, dispersion and emulsification capacity of cleansing systems, makes foam delicate and dense, and improves rinsing cleanliness.
• Long-Term System Stabilization: Stabilizes formula viscosity and uniformity, avoids delamination and system instability caused by long-term storage, and improves product shelf stability.
• Wide Compatibility & High Cost Performance: Compatible with all kinds of surfactants and daily chemical formulas, low dosage and significant effect, reduces auxiliary types and comprehensive formula cost.
Applications
• Facial Cleansing Products: Suitable for weakly alkaline amino acid cleansers, cleansing milk and cleansing foam, stabilize system pH, optimize foaming and cleaning power, and improve product mildness.
• Hair & Body Cleansing Series: Widely used in shampoo, body wash, hand sanitizer and soap-based cleansing products, soften water quality, prevent turbidity and delamination, and enhance decontamination synergy.
• Neutral & Weak Alkaline Skincare: Applied in neutral and weak alkaline lotion, cream and functional water-based skincare formulas for water quality conditioning and long-term system stabilization.
• Transparent Water-Based Daily Chemicals: Ideal for transparent cleansing water and light transparent daily chemical formulas to ensure long-term clear appearance without flocculation and impurities.
• Long-Shelf-Life Formulas: Used in daily chemical products requiring long-term storage stability, delay formula aging and oxidation deterioration, and reduce defective product rate.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of cosmetic grade Tetrasodium Pyrophosphate?
A1: The standard MOQ is 1KG, and sample orders are supported for formula testing and stability trial production.
• Q2: What certification documents can be provided?
A2: Complete COA, MSDS and full set of global customs clearance documents are available to support export declaration.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Conventional addition ratio is 0.02%-0.1% for skincare products, 0.05%-0.2% for cleansing and hair care products, adjustable according to pH regulation and system stabilization requirements.
• Q4: What is the difference between TSPP and TSP?
A4: TSPP has moderate alkalinity with mild regulation performance, no excessive pH fluctuation, more suitable for weakly alkaline fine formulas; TSP has strong alkalinity, suitable for high-alkali cleaning systems. TSPP has better viscosity stabilization and color protection performance.
• Q5: Will TSPP affect product skin feel and fragrance?
A5: No, high-purity cosmetic grade with ultra-low impurities and stable properties. Standard dosage will not change the skin feel, viscosity and fragrance of finished products, ensuring pure product texture.
• Q6: Do you support stable large-batch supply all year round?
A6: Sufficient factory production capacity ensures continuous, stable and large-volume supply throughout the year to support long-term cooperative orders and customized formula demands.
