Claims6
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.
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.
