Cosmetic Grade Sodium Hexametaphosphate-CAS 68915-31-1
Cosmetic-grade Sodium Hexametaphosphate (SHMP) is a high-efficiency inorganic chelating and stabilizing agent specially developed for cosmetic and daily chemical formulas. It has strong selective chelating ability for calcium, magnesium, iron and other metal ions in water and raw materials.
It can effectively eliminate the adverse effects of hard water metal ions on cosmetic systems, achieve water softening effect, and avoid formula turbidity, flocculation and precipitation problems caused by hard water. Meanwhile, SHMP can shield metal ion activity, inhibit catalytic oxidation failure of functional ingredients, prevent cosmetic discoloration, yellowing and odor deterioration during long-term storage, and significantly improve product stability and appearance quality.
It can effectively balance and stabilize the pH value of aqueous cosmetic formulas, avoid pH drift and system instability caused by raw material differences and environmental changes.
With high purity, low impurity and mild properties, it will not irritate the skin or affect the original skin feel and fragrance of finished products. It is an essential functional auxiliary raw material for solving turbidity, discoloration and short shelf-life pain points in water-based daily chemical and skin care formulas.
Key Benefits
• Anti-Oxidation & Anti-Discoloration Stabilization: Shield metal catalytic activity, inhibit ingredient oxidation failure, prevent product yellowing, darkening and odor deterioration, maintain long-term clear appearance.
• Stable pH & Improve Formula Stability: Effectively buffer pH fluctuation of water-based formulas, avoid system stratification and viscosity change caused by environmental and raw material differences.
• Improve Shelf Life & Reduce Defect Rate: Effectively delay formula aging and ingredient failure, extend product shelf life, reduce defective products caused by turbidity and discoloration.
• Mild & High Compatibility: Cosmetic high-purity grade, low impurity and low irritation, no impact on skin feel, fragrance and viscosity of finished products, compatible with all water-based cosmetic systems.
• Low Dosage & High Cost Performance: Excellent stabilizing effect with ultra-low addition, simple formula operation, significant cost reduction for cosmetic mass production.
Applications
• Facial Skin Care Products: Added in toner, moisturizing essence, facial lotion, cream and gel skincare products to stabilize water quality, prevent discoloration and turbidity, and maintain clear and translucent product texture.
• Daily Cleansing & Hair Care: Widely used in shampoo, conditioner, body wash, hand sanitizer and facial cleanser to soften water quality, stabilize surfactant system and avoid product delamination and turbidity.
• Body Care Series: Applied in body lotion, body cream and moisturizing spray to inhibit ingredient oxidation, maintain stable efficacy and extend product shelf life.
• Transparent Water-Based Formula: Special stabilizer for transparent toner, transparent gel and light water-based cosmetics to ensure long-term clear appearance without flocculation.
• Functional Additive Formula: Used in formulas containing plant extracts, vitamin components and easily oxidized functional ingredients to protect active ingredients and prevent oxidation failure.
