Aluminum Distearate

Product Description

Green Stone Swiss supplies high-purity Aluminum Distearate under GMP-aligned manufacturing controls, supporting consistent batch quality for professional cosmetic and personal care brands. Our direct factory supply model provides reliable bulk availability with complete technical documentation and free sample support for formulation screening.

Aluminum Distearate (hydroxyaluminum distearate) is an aluminum salt of stearic acid used as a multifunctional formulation aid. In CosIng, it is recognized for viscosity controlling, emulsion stabilising, opacifying, and anticaking functions—helping thicken anhydrous and oil-rich systems, improve emulsion integrity, reduce translucency where opacity is desired, and support free-flowing powder behavior.

As brands expand cream, stick, mascara, and color-cosmetic platforms that need dependable rheology and optical control, cosmetic-grade Aluminum Distearate remains a practical B2B building block for formulators seeking reproducible texture, suspension support, and process-friendly metallic soap performance.

Key Benefits & Applications

Aluminum Distearate is a CosIng-listed metallic soap widely used as a viscosity controller, emulsion stabilizer, opacifier, and anticaking aid in cosmetic systems.

• Builds and adjusts viscosity in anhydrous sticks, balms, and oil-rich bases
• Supports emulsion integrity and pigment/suspension stability in creams and makeup
• Provides opacifying support to reduce transparency in tinted and cream formats
• Helps limit powder caking and improve free-flow in pressed and loose powder systems
• Suitable for creams, sticks, mascaras, foundations, and color-cosmetic bases
• Suggested use level: Typical 0.5–5.0% depending on system and target rheology

Formulation Guidelines

Use these guidelines to integrate Aluminum Distearate as a formulation aid for rheology, emulsion stability, and optical control.

• Suggested Use Level: Typical 0.5–5.0% in final formulation; optimize by viscosity and opacity targets
• Phase: Prefer oil-phase or anhydrous incorporation; disperse thoroughly before emulsification
• Processing: Heat with the oil phase as needed for uniform melt/dispersion; avoid incomplete wetting that can cause grit
• Compatibility: Generally compatible with common emollients and waxes; evaluate electrolyte load and strong acids/bases case by case
• Stability: Protect from humidity during storage and handling to maintain free-flowing powder quality
• Combine with Magnesium Aluminum Silicate for complementary emulsion rheology and suspension support in cream systems.
