Stearate Specification
Stearate (CAS NO.646-29-7) is the anion form of stearic acid. Formula is C17H35COO−. Stearate is a salt or ester of stearic acid.
Stearic acid is a colorless, odorless, waxlike fatty acid, occurring in natural animal and vegetable fats and used in making soaps, candles, lubricants, and other products
Stearic Acid is a typical example of a fatty acid, which are essentially long hydrocarbon chains containing a carboxyl group at one end and a methyl group at the other. The chain lengths can vary from 3 (propionic acid) to 24 (lignoceric acid) but the majority of fatty acids found in hydrogenated vegetable or animal oils are around C16-C20 in length. Stearic acid is a saturated acid, since there are no double bonds between neighbouring carbon atoms. This means that the hydrocarbon chain is flexible and can roll up into a ball or stetch out into a long zig-zag.
