Patent ID: 8378131

Claim:
A co-salt comprised of at least one polyunsaturated fatty acid anion and at least one co-anion; said co-anion being an anion which is not a fatty acid anion and that is less waxy, less hydrophobic and more structurally rigid than said at least one polyunsaturated fatty acid anion; said co-salt further comprising at least one cation which is ionically bonded with said at least one polyunsaturated fatty acid anion and said at least one co-anion to define a fatty acid salt component of the co-salt and a co-anion salt component of the co-salt; wherein the at least one polyunsaturated fatty acid anion comprises at least one omega-3 fatty acid and/or at least one omega-6 fatty acid; said at least one co-anion is chosen from the group consisting of citric acid, lactic acid, phosphoric acid, fumaric acid, malic acid, gluconic acid, acetic acid, ascorbic acid, aspartic acid, sulfuric acid, formic acid, propionic acid, succinic acid, adipic acid, salicyclic acid, benzoic acid, phthalic acid, maleic acid, malonic acid, pyruvic acid, sorbic acid, caprylic acid, glutaric acid, pimelic acid, glucoheptanoic acid, glycerophosphoric acid, glutamic acid, glutathione, lecithin, phenylalanine, valine, leucine, isoleucine, threonine, methionine, lysine, arginine, histidine and combinations thereof; said at least one cation being chosen from the group consisting of calcium, magnesium, zinc, iron, manganese, copper, potassium, sodium, ammonium, and combinations thereof; and the weight ratio of the fatty acid anion to the non-fatty acid co-anion in the co-salt ranges from about 90:10 to about 10:90.
