Patent ID: 7820842

Claim:
A method for the preparation of a free-flowing, storage-stable fatty acid metal salt product comprising: forming a reactive admixture comprising (a) an unsaturated fatty acid glyceride feedstock comprising at least one fatty acid with more than three double bonds; (b) an antioxidant-effective amount of a stabilizing oil to provide an improvement in storage stability; and (c) from about 1 mol to about 3 mol of at least one monovalent metal hydroxide or at least one divalent metal hydroxide; and heating the admixture to a temperature at which said fatty acid glycerides saponify to form fatty acid metal salts until a free-flowing, storage-stable product is obtained; wherein said stabilizing oil has a fatty acid profile that is more resistant to oxidation than the fatty acid profile of said glyceride feedstock; wherein said monovalent metal is potassium; and wherein said divalent metal is selected from the group consisting of calcium, copper, magnesium, and zinc.
