Description of CAS NO:637-12-7 Aluminium stearate

Aluminium stearate, also known as aluminum tristearate, is a white, wax-like powder (metallic soap) that dissolves well in vegetable oils upon heating . It is soluble in glycol, alkali, BTX, chlorinated hydrocarbons . It exhibits good gelling and thickening action, excellent water repellence, transparency and a synergistic effect with zinc stearate or calcium stearate .

Applications of CAS NO:637-12-7 Aluminium stearate

1.Paints and Coatings
Aluminium Stearate is widely used in the paint industry due to its properties as a gelling agent. It imparts a thixotropic character to paints, which helps in preventing the settling of pigments during storage. In varnishes, it contributes to the flatting effect and improves the suspension of pigments .

2.Plastic Manufacturing
In the field of plastics, Aluminium Stearate serves as a lubricant, facilitating the molding process. It helps in the production of thermosetting plastics and polyamides by acting as a release agent, which prevents the finished products from sticking to the molds .

3.Cement and Construction
The compound is utilized in cement production for its waterproofing qualities. It helps in air entrainment and enhances the durability of concrete by reducing the permeability to water. This application is particularly important in structures exposed to moisture or submerged in water

4.Leather and Textile Industry
Aluminium Stearate is employed as a water repellent for leather and textiles. It forms a protective layer that repels water, thereby increasing the material’s longevity and preserving its quality against moisture-induced damage

5.Photographic Materials
In the photography industry, Aluminium Stearate is used in light-sensitive photographic compositions. It plays a role in the emulsion preparation, affecting the dispersion of photographic grains and improving the stability of the final product

6.Lubricants and Greases
As a thickener in lubricating oils and greases, Aluminium Stearate contributes to the consistency and performance of these products. It ensures that the lubricants maintain their properties under various temperature conditions, providing reliable performance

7.Pharmaceutical and Cosmetic Applications
Aluminium Stearate has potential applications in pharmaceuticals and cosmetics. It can act as a viscosity modifier, emulsifier, and anti-caking agent in various formulations, enhancing the texture and stability of the products

8.Environmental Applications
Recent research has explored the use of Aluminium Stearate in environmental applications, such as a substrate for anaerobic bacteria in denitrification processes. This application is crucial for the treatment of effluents and wastewater management
