Aluminium Stearate
Aluminium stearate is an aluminum salt of stearic acid, produced through the reaction of stearic acid with aluminum compounds. It appears as a fine white to off-white powder and is highly hydrophobic in nature. With its unique long-chain fatty structure and aluminum core, aluminium stearate exhibits excellent water-repellent, thickening, stabilizing, and lubricating properties.
These characteristics make aluminium stearate widely used across multiple industries, including pharmaceuticals, cosmetics, paints & coatings, plastics, rubber, inks, adhesives, and industrial lubricants.
At Evergreen Chemical Company Thailand, we supply premium-grade aluminium stearate powder engineered to meet the demanding requirements of high-performance applications. Manufactured under strict quality control systems and compliant with international standards such as ISO and REACH, our aluminium stearate delivers consistent quality, stability, and performance batch after batch.

Aluminium Stearate Properties and Features
1. Thickening & Gelling Agent
Aluminium stearate is an effective thickening and gelling agent, particularly in non-aqueous and oil-based systems. It enhances viscosity and structure in formulations such as ointments, greases, paints, and coatings, ensuring stable and uniform consistency.
2. Water Repellent & Moisture Barrier
Due to its hydrophobic nature, aluminium stearate provides excellent water-repellent properties. It is commonly used to improve moisture resistance in pharmaceuticals, cosmetics, coatings, and construction-related products.
3. Stabilizer & Anti-Settling Agent
Aluminium stearate acts as a stabilizer and anti-settling agent, preventing pigment or filler separation in paints, inks, and coatings. This improves shelf life, dispersion stability, and overall product performance.
4. Lubricant & Processing Aid
In plastics and rubber applications, aluminium stearate functions as a lubricant and processing aid, reducing friction during molding, extrusion, and compounding processes. This enhances process efficiency and surface finish of final products.
5. Controlled Release & Flow Modifier
Aluminium stearate is widely used in pharmaceutical formulations as a release-controlling agent and flow modifier. It improves powder flowability and supports consistent dosing in tablet and capsule manufacturing.
Aluminium Stearate Applications
Aluminium Stearate is widely applied in various industries, particularly in Plastic Additives and Lubricant Additives, where it functions as a lubricant, release agent, thickener, and processing aid. It enhances texture and stability in pharmaceutical and cosmetic formulations, improves pigment dispersion and rheology control in paints and coatings, supports efficient plastic and rubber processing, and provides thickening, water resistance, and lubrication in a wide range of industrial products.
1. Pharmaceutical Industry
Aluminium stearate is commonly used in ointments, creams, and topical formulations as a thickener, stabilizer, and moisture barrier. It also serves as a flow enhancer and release-controlling agent in solid dosage forms.
2. Cosmetics & Personal Care
In cosmetics, aluminium stearate improves texture, spreadability, and stability in products such as creams, lotions, foundations, and sunscreens. Its water-repellent properties help enhance product durability and skin feel.
3. Paints, Coatings & Inks
Aluminium stearate functions as an anti-settling agent and rheology modifier in paints, coatings, and inks. It helps maintain uniform pigment dispersion, prevents sagging, and improves application performance.
4. Plastics & Rubber Industry
In plastic and rubber processing, aluminium stearate is used as a lubricant, release agent, and processing aid. It improves mold release, reduces surface defects, and enhances production efficiency.
5. Industrial Products
Aluminium stearate is utilized in greases, adhesives, sealants, and other industrial formulations where thickening, water resistance, and lubrication are required.
