Kaolin

Product Description

Green Stone Swiss supplies high-purity cosmetic-grade Kaolin processed under GMP-aligned quality systems for consistent whiteness, controlled particle profile, and reliable bulk availability. Our direct factory supply model supports global skincare and color cosmetics brands with full technical documentation, COA/TDS packages, and free sample support for formulation screening.

Kaolin is a naturally occurring hydrated aluminum silicate clay (also referenced as CI 77004) listed in CosIng as an absorbent, abrasive, anticaking, bulking, opacifying, and colorant ingredient. Its fine lamellar mineral structure provides oil and moisture uptake, mild mechanical cleansing, and opacity/whiteness support in rinse-off masks, powder systems, and mattifying bases—without positioning as a leave-on biological hero active.

As demand grows for clean mineral textures in clay masks, oil-control cleansers, and powder makeup, Kaolin remains a high-utility formulation mineral for premium personal care lines seeking stable factory-direct supply and documented cosmetic-grade quality.

Key Benefits & Applications

Kaolin is a versatile mineral clay used for absorbency, mild cleansing, and opacity control in masks, powders, and oil-control systems.

• Absorbs excess sebum and surface impurities in rinse-off clay masks and cleansers
• Provides mild abrasive action for gentle physical cleansing and skin-texture refinement
• Supports opacity, whiteness, and soft-focus coverage in powder and tinted mineral systems
• Improves powder flow and anticaking performance in dry cosmetic bases
• Ideal for clay masks, face powders, foundations, dry shampoo, and mattifying emulsions
• Typical use level: 4–20% in leave-on/powder systems; higher Typical levels in rinse-off masks (confirm with TDS)

Formulation Guidelines

Disperse Kaolin as an insoluble mineral solid and optimize suspension, sensory, and absorbency targets by product type.

• Suggested Use Level: Typical 4–20% in powders/creams; rinse-off clay masks commonly use higher Typical levels up to mask-paste loadings
• Dispersion: Predisperse in the water or glycerin phase with high-shear mixing; avoid agglomerates before thickeners set
• Suspension: Pair with suitable thickeners/rheology modifiers to maintain uniform mineral suspension
• Compatibility: Chemically inert in most systems; validate shade, viscosity, and drying feel with pigments and humectants
• Handling: Control dusting during weighing; keep containers sealed to prevent moisture uptake
• Combine with Silica for complementary powder absorbency, slip, and soft-focus texture in mineral systems.
