Aluminium Stearate

Aluminum stearate is a white, wax-like powder (metallic soap) that dissolves in mineral spirits or hot oil.

It is insoluble in water, alcohol and ether. However, it is soluble in glycol, alkali, BTX, chlorinated hyrdocarbons. It dissolves well in vegetable oils on heating and if high concentration is used, on cooling gelling is seen.

Aluminum stearate is made via the precipitation process using high quality stearic acid and exhibits the following properties: Good gelling and thickening action, excellent water repellency, transparency and a synergistic effect with zinc stearate or calcium stearate.

Aluminium Stearate is used as an emulsifier in cosmetics. It is also used as lubricant in polyamides and in thermosetting of plastics. Its use as a water repellent agent and hydrophobic agent makes it useful to be used as a waterproofing agent in paint industry. Aluminium stearate is used as thickening agent in production of varnishes and lacquers. It also finds use as an anti-caking agent in petroleum products.
