Zinc carboxylate clays and zinc carboxylate organoclays, methods for their preparation, and compositions containing the same are disclosed. The methods comprise either mixing a zinc clay composition with a carboxylic acid, or mixing a carboxylic acid with a zinc ammonia complex solution, then combining the resulting zinc carboxylate salt with a slurry or suspension of a cation-exchangeable clay, to prepare the zinc carboxylate clay. These clays can be further intercalated with quaternary ammonium salts to make zinc carboxylate organoclays. The present clays may be used in compositions and/or as additives in rubber and plastic formulations and products and in catalyst formulations.
