aluminium monostearate

Aluminium monostearate is an organic compound that is the aluminum salt of stearic acid. It has the molecular formula Al(OH)2C18H35O2 and is also known as dihydroxyaluminium or dihydroxy(stearato)aluminium. In the pharmaceutical industry, it is primarily used as an excipient—serving as an anticaking agent, colorant, emulsion stabilizer, and viscosity-increasing agent. It forms gels for packaging pharmaceuticals and in cosmetic preparations. While generally considered safe for use in food and pharmaceuticals by regulatory agencies such as the FDA, excessive exposure may lead to accumulation of aluminum in the body[1][2][3][4].
