Aluminium Stearate

Aluminium stearate is a white, odorless powder with interesting properties that make it useful in many industries. Here's a breakdown of its key features:

• Chemical composition: It's an aluminum salt of stearic acid, a fatty acid.
• Water repellency: Aluminium stearate is hydrophobic, meaning it repels water. This makes it useful for waterproofing materials like leather, rope, and even cement.
• Lubrication: It acts as a lubricant, reducing friction in plastics and during the production of some other materials.
• Thickening: Aluminium stearate can thicken paints, inks, and greases.
• Other properties: It has good adhesion to metal surfaces, is transparent, and can work well with other metallic stearates.

Aluminium stearate is generally considered safe for use in various applications. However, as with any material, it's always best to consult with a safety data sheet (SDS) for specific handling recommendations.
