DEFINITION

Aluminum Monostearate is a compound of aluminum with a mixture of solid organic acids obtained from sources of vegetable or animal origin, and consists mainly of variable proportions of aluminum monostearate (C₁₈H₃₇AlO₄) and aluminum monopalmitate (C₁₆H₃₃AlO₄). The content of stearic acid in the fatty acid fraction is NLT 40.0% of the total content. The sum of stearic acid and palmitic acid in the fatty acid fraction is NLT 90.0% of the total content. Aluminum Monostearate contains the equivalent of NLT 14.7% and NMT 16.7% of aluminum oxide (Al₂O₃) on the dried basis. Additionally, it contains small amounts of the aluminum salts of other fatty acids.
