Aluminum Stearoyl Glutamate

Product Description

Manufactured through advanced amino acid synthesis and strictly maintained under direct factory supply standards, our High Purity Aluminum Stearoyl Glutamate ensures premium quality and consistency for professional cosmetic formulators. Functioning as an advanced hydrophobic surface treatment, it chemically bonds to pigment particles, imparting excellent water resistance and a remarkably soft, skin-mimicking sensory profile. Perfectly aligning with the surging market demand for long-wear, sweat-resistant, and high-fidelity makeup, this performance-driven ingredient offers immense commercial value for premium foundation and sun care lines.

Product Specification

• INCI Name: Aluminum Stearoyl Glutamate
• CAS Number: 31692-74-7
• Chemical Class: Amino Acid Derivative / Surface Treatment
• Appearance: Fine white to off-white powder
• Purity: ≥98.0% (High Purity)
• Solubility: Highly lipophilic; insoluble in water

Key Benefits & Applications

• Superior Hydrophobicity: Forms a tightly bound lipophilic layer around pigment particles, dramatically improving water and sweat resistance in long-wear cosmetic formulations.
• Enhanced Pigment Dispersion: Prevents the agglomeration of inorganic UV filters and colorants in the lipid phase, ensuring a homogeneous distribution and maximum color payoff.
• Sensory Profile Optimization: Imparts a uniquely smooth, non-drying, and creamy skin feel, minimizing the chalky texture traditionally associated with heavy pigment loads.
• Applications: Essential for high-coverage liquid foundations, pressed powders, water-resistant sunscreens, and premium lip color lines.

Formulation Guidelines

• Maximum Safe Concentration: Typical usage levels range from 2.0% to 5.0% based on total pigment weight for surface coating, or 0.5% to 2.0% as a texture modifier in the bulk formula (Suggested).
• Solubility: Highly lipophilic and insoluble in water. Pre-dispersion with pigments or within the lipid matrix is required.
• Processing Phase: Best incorporated during the dry blending phase for powders or dispersed into the heated oil phase (up to 85°C) to ensure optimal coating efficacy and thermal stability.
• Synergy: Combine with Squalane to facilitate a seamless, "second-skin" spreadability while maintaining the structural integrity of the hydrophobic barrier.
