Abstract
Bimetal chelates are prepared from a solution formed by adding to a solvent one or more polyfunctional acids with basic salts of two or more coordination elements listed in Groups IIIA to VIIIA, Groups IB to IIIB, of periods 4 and 5 and aluminum in Group IIIB, period 3 of The Periodic Table of the Elements and recovering the chelate. Such chelates can be used to formulate useful products.
Claims11
A method of forming a bimetal chelate, the method comprising
- forming a solution by adding to a solvent (i) a polyfunctional carboxylic acid and (ii) basic salts of two or more coordination elements selected from one or more of copper, silver, gold, aluminum, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, and indium;
- and
- recovering a bimetal chelate that includes the two or more coordination elements joined to a central unit derived from the polyfunctional carboxylic acid.
A method comprising:
- formulating a product by combining a pharmaceutically or dermatologically acceptable carrier with a chelate formed by a polyfunctional carboxylic acid with basic salts of two or more coordination elements selected from one or more of copper, silver, gold, aluminum, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, and indium, wherein the chelate includes two or more coordination elements are joined to a central unit derived from the polyfunctional carboxylic acid.
