Cosmetic Calcium Hydrogen Phosphate-CAS 7789-77-7
Cosmetic Grade Calcium Hydrogen Phosphate Dihydrate is a high-purity crystalline inorganic functional powder specially used for color cosmetics. With stable dihydrate crystal structure, moderate hardness and excellent compression resistance, it perfectly solves the molding defects of traditional talc powder and kaolin powder such as soft texture, easy powder dropping and poor scratch resistance.
It can significantly enhance the hardness and compactness of pressed powder products, making the powder cake firm and not easy to break or scratch. With mild oil absorption and natural matting effect, it balances skin oil and creates soft matte skin texture without dry and tight feeling.
It has excellent pigment compatibility and color stabilization, uniform coloring and strong skin adhesion. Safe, mild and chemically inert, it is an essential core filler for high-quality durable and scratch-resistant powder makeup.
Key Benefits
• High Hardness & Anti-Scratch, Firm Molding: Unique crystal structure improves powder compression hardness and compactness, effectively prevents powder cake from breaking, peeling and surface scratching, improves product durability and yield.
• Moderate Oil Control & Natural Matte: Balanced oil absorption value absorbs excess facial grease without dryness, eliminates oily shine, creates natural soft-focus matte makeup, and optimizes skin feeling.
• Smooth Texture & Strong Fitting: Fine and uniform crystal particles, no gritty residue, excellent spreadability, smooth makeup application, improve powder adhesion and prevent floating powder.
• Stable Color Rendering & No Color Migration: Chemically inert without pigment reaction, effectively stabilizes color dispersion, improves color uniformity and saturation, avoids color fading and mottling.
• Mild & Safe Skin-Friendly: High-purity purification process, ultra-low heavy metal impurities, non-toxic and non-irritating, compliant with global cosmetic standards, safe for long-term facial contact.
• High Compatibility & Mass Production Stable: Compatible with all powder makeup systems, stable batch particle size and hardness indicators, consistent product performance, friendly for large-scale standardized production.
Applications
• Pressed Powder & Setting Powder Series: Core hardening and shaping filler for pressed powder, setting powder cake and repair powder cake, improves product hardness and abrasion resistance, solves loose powder and easy breaking problems.
• Long-Lasting Matte Base Makeup: Applied in foundation cake, powder foundation and oil-control fixing powder, assists in oil control and matting, stabilizes base makeup effect, and prolongs makeup lasting time.
• Eye & Cheek Color Cosmetics: Widely used in eyeshadow, blush, contour powder and highlight powder, optimizes powder molding and texture, makes color rendering delicate and uniform, and enhances makeup three-dimensional sense.
• High-Durability Daily Makeup: Suitable for daily wear durable powder cosmetics, improves product drop resistance and scratch resistance, reduces daily wear and tear damage, and extends product service life.
• Soft Matte Functional Formulas: Used in various natural matte skin-friendly makeup formulas, balances oil control effect and skin comfort, and creates high-grade soft-focus makeup texture.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Calcium Hydrogen Phosphate?
A1: The standard MOQ is 25KG, support sample orders for formula testing and trial production, and support customized mesh fineness specifications.
• Q2: Is cosmetic calcium hydrogen phosphate safe for skin?
A2: Yes. Adopts cosmetic-grade deep purification and high-temperature sterilization process, ultra-low heavy metal and impurity content, no harmful residues. Non-toxic, non-irritating and non-sensitizing, fully compliant with international cosmetic safety standards, safe for long-term facial skin contact.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Pressed powder & powder cake: 10.0%–30.0%; Loose setting powder: 5.0%–15.0%; Eye & cheek color cosmetics: 8.0%–20.0%; Matte long-wear makeup: 6.0%–18.0%, adjustable according to required powder hardness and matting effect.
• Q4: What is the difference between calcium hydrogen phosphate and talc powder?
A4: Talc powder is soft with excellent smoothness but poor hardness and easy to scratch and drop powder. Calcium hydrogen phosphate has higher crystal hardness and better compression molding performance, which can significantly improve powder firmness and scratch resistance, solving the defect of soft powder texture, and is a high-grade shaping filler for durable powder makeup.
• Q5: What formula systems is it compatible with?
A5: Chemically inert and stable, perfectly compatible with all powder cosmetic systems, widely used in various pressed powder and loose powder formulas. Uniform dispersion without agglomeration, no adverse reaction with pigments and conventional cosmetic raw materials.
• Q6: What are the formula usage notes?
A6: It is recommended to mix and disperse with other powder materials at high speed to ensure uniform particle distribution; reasonably match with soft powder to balance hardness and skin feel; avoid excessive dosage leading to slightly dry texture; seal and store finished products to prevent moisture absorption.
• Q7: Do you support stable mass supply and customized specifications?
A7: Strictly control powder purity, whiteness and particle size to ensure stable hardness and molding performance of each batch. Support customized mesh fineness. Sufficient inventory all year round supports long-term bulk orders and professional formula technical guidance.
