Chemical compositions and methods of making them

1. A composition comprising

a dermatologically acceptable carrier; and

a bimetal complex formed by an aqueous solution containing a compound selected from polycarboxylic acids, polyamines and amino acids having at least two carboxylic acid groups with two or more coordination elements selected from 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, indium and tin.

2. A composition as in claim 1 wherein the coordination elements are Copper and Zinc.

3. A composition as in claim 1 wherein the compound is an amino acid having at least two carboxylic acid groups.

4. A composition as in claim 1 wherein the compound is a glutamic acid or aspartic acid.

5. A composition comprising

a dermatologically acceptable carrier; and

one or more copper molecules;

one or more zinc molecules; and

a central unit, wherein the central unit comprises at least one compound selected from polycarboxylic acids, polyamines and amino acids having at least two carboxylic acid groups and the center unit bridges the one or more copper molecules and one or more zinc molecules by coordinate bonding.

6. A composition as in claim 5 wherein the central unit comprises at least one compound is an amino acid having at least two carboxylic acid groups.
