The gel comprises a carboxylate-containing polymer and a chromic carboxylate crosslinking agent.

Carboxylate ligands can be used.

A mixture of: dodecylphenyl dodecylhydroxybenzenecarboxylate

The ligand(s) of the complex typically independently comprise a carboxylate, or a derivative of a carboxylate, having anti-inflammatory activity.

In said formula (I), wherein R1, R2, R3, R4 and R5 independently represent each hydrogen, an aliphatic carboxylate or an aromatic carboxylate.

These rubber compositions comprise a metal carboxylate.

The catalyst is selected from the group consisting of a chelated zinc carboxylate, a chelated bismuth carboxylate or a combination thereof.

The molar ratio of the carbonate groups in the carbonate and the carboxylate groups in the carboxylate is 0.85-3.40.

The compositions comprise aqueous solutions of a mixture of a C1-C2 carboxylate salt with a C3-C5 carboxylate salt.

In one embodiment of the invention the carboxylate based brine solution consists of a carboxylate salt dissolved in water.

The methods comprise administering a therapeutic amount of a complex of metal and a carboxylate, or a derivative of a carboxylate, having anti-inflammatory activity.

Suitable complexes include a complex of a metal and a carboxylate, or a derivative of a carboxylate, having anti-inflammatory activity.

The counter ion is preferably a carboxylate anion.

This improves the quality of the metal carboxylate.

Borated versions of the overbased carboxylate are preferred and are obtained by reacting a boron reactant such as boric acid with an overbased carboxylate.
