Cosmetic Grade Magnesium Aluminum Silicate Powder-CAS 12511-31-6
Cosmetic Grade Magnesium Aluminum Silicate is a high-purity natural mineral functional raw material specially used for cosmetic rheology adjustment and system stabilization.
With unique layered crystal structure, it has excellent water absorption and swelling thixotropy, which can form a stable three-dimensional gel network in the water phase system. It effectively increases formula viscosity, uniformly suspend solid particles and pigments, and maintain long-term system homogeneity.
Different from chemical thickeners with poor tolerance and easy irritation, natural magnesium aluminum silicate has mild properties, strong formula compatibility, and will not affect the original efficacy and fragrance of cosmetic products.
It can significantly improve the smoothness, matte texture and application experience of skincare and makeup products, solve the problems of easy flow, powder sinking and short shelf life of low-viscosity formulas, and is an indispensable core auxiliary material in high-quality cosmetic formulas.
Key Benefits
• Powerful Suspending & Anti-Settling: Build stable three-dimensional gel network, effectively suspend inorganic pigments, functional particles and bead materials, completely solve formula precipitation and powder sinking problems.
• Excellent Thixotropic Rheology Control: Thickens statically and flows dynamically, moderate viscosity, easy to stir and process, smooth and non-dragging during application, balance product stability and user experience perfectly.
• Natural Mild & Skin-Friendly: Pure natural mineral source, no chemical residues, non-irritating and non-sensitizing, safe for long-term skin contact, suitable for sensitive skin formulas.
• Optimize Skin Feel & Matte Texture: Improve product ductility, reduce greasy feeling and sticky residue, endow skincare and makeup with silky, refreshing and natural matte finish.
• Enhance Formula Stability: Improve high and low temperature resistance and storage stability of cosmetics, prevent emulsion delamination, water-oil separation and deterioration, extend product shelf life.
• Wide Compatibility & Mass Production Friendly: Compatible with water, oil and emulsion full-system formulas, stable batch performance, no adverse reaction with various cosmetic raw materials, suitable for large-scale standardized production.
Applications
• Daily Skincare Products: Widely used in moisturizing lotion, facial cream, gel cream, toner emulsion and essence lotion, adjust formula viscosity, optimize silky skin feel, prevent active ingredient precipitation.
• Sunscreen Products: Used in physical sunscreen lotion and cream, uniformly suspend sunscreen powder, avoid powder sinking and uneven sun protection, improve sunscreen texture and durability.
• Base Makeup Products: Applied in foundation, concealer, BB cream and primer, stabilize pigment dispersion, prevent floating color and color difference, improve makeup spreadability and matte finish.
• Fluid Color Cosmetics: Suitable for liquid blush, liquid eyeshadow, contour liquid and tinted lotion, maintain uniform color system, prevent particle precipitation and formula delamination.
• Suspension Functional Formulas: Ideal for formulas containing functional beads, plant particles and trace active powders, play a stable suspending and homogeneous role.
• High-Stability Emulsion System: Assist in stabilizing oil-water emulsion structure, improve formula high and low temperature stability, solve common problems of emulsion delamination and water bleeding.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Magnesium Aluminum Silicate?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and trial production.
• Q2: Is magnesium aluminum silicate safe for skincare and sensitive skin?
A2: Yes. It is a natural inorganic mineral raw material without chemical irritants, low heavy metal and non-sensitizing. It complies with global cosmetic safety standards, mild and safe for long-term skin contact, suitable for sensitive skin and mild skincare formulas.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Lotion & essence: 0.2%–1.0%; Cream & gel: 1.0%–3.0%; Sunscreen products: 0.5%–2.0%; Liquid makeup: 0.3%–1.5%; Suspension particle formulas: 1.0%–4.0%, adjustable according to target viscosity and suspension stability requirements.
• Q4: What is the difference between magnesium aluminum silicate and chemical thickeners?
A4: Magnesium aluminum silicate is natural mineral origin, mild and non-irritating, with excellent thixotropy and suspension. Chemical thickeners are prone to sticky skin, poor fluidity and formula intolerance. Natural silicate can optimize matte skin feel while stabilizing the system, with higher safety and better comprehensive formula performance.
• Q5: Can it be compounded with other cosmetic raw materials?
A5: Yes. It has excellent compatibility with thickeners, emulsifiers, moisturizers and inorganic pigments. It can be used synergistically with various raw materials to improve formula stability and makeup texture without adverse reactions.
• Q6: What are the formula matching notes?
A6: Pre-disperse and hydrate fully in water phase before use to give full play to thickening and suspending effect; adjust dosage according to formula viscosity demand; avoid excessive high dosage leading to heavy texture; match with emulsifier system to optimize emulsion stability.
• Q7: Do you support stable mass supply and customized processing?
A7: Strict batch index control ensures stable viscosity and thixotropy. Support customized fineness and viscosity grade. Sufficient inventory all year round supports long-term bulk orders and professional formula technical guidance.
