PURPOSE:To provide a dispersant having excellent oil dispersibility to a non- polar or polar powder, obtained by containing high purity sorbitol fatty acid monoester which is an esterified product of sorbitol and higher fatty acid. CONSTITUTION:An oil dispersant comprises an esterified product of sorbitol and 12C or more higher fatty acid containing 50% or more of sorbitol fatty acid ester of which the sorbitor fatty acid monoester content is 60wt% or more and shows excellent oil dispersibility to a polar powder such as red oxide or titanium similarily to a non-polar powder such as carbon. As the above-mentioned higher fatty acid, straight chain or branched chain saturated or unsaturated fatty acids, such as, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, isopalmitic acid or isostearic acid are used.
