Aluminium Stearate

Aluminium Stearate or (aluminum tristearate) is a white coloured powder, wax – like powder (metallic soap) that dissolves well in vegetable oils upon heating. It is soluble in glycol, alkali, BTX, chlorinated hydrocarbons. If aluminium stearate is in high concentration, gelling can be seen upon cooling. It exhibits the following properties: good gelling and thickening action, excellent water repellence, transparency and a synergistic effect with zinc stearate or calcium stearate. Aluminium stearate exhibits a relatively high solubility in hydrocarbon solvents (such as mineral spirits) when compared to other metallic stearates. It is insoluble in water, alcohol and ether; but when hot, it is readily soluble in benzene, acids and common solvents.
