This invention relates to bioerodible deodorant formulations for use on the human body employing the controlled release of water-soluble cationic germicides from hydrophobic carboxylic acid polymer matrices. A broad spectrum of germicide release rates is achieved by varying the choices of matrix and germicide and the loading levels.

A sustained release bioerodible deodorant formulation for use on the human body consisting essentially of a cosmetically acceptable, non aqueous organic solvent solution containing 2 to 20% by weight of a mixture of a quaternary ammonium germicidal material and a carboxylic polymer having the general formula: [Figure] in which R1, R2,-Rn are organic radicals selected from the group consisting of hydrocarbon radicals and hetero-atom containing radicals, in which the R\s are selected to provide an average of from 8 to 22 carbon atoms for each acidic carboxylic hydrogen and in which the value of n is selected to provide a molecular weight of about 10,000 to 800,000; the molar ratio of said carboxylic polymer to said germicidal material being from about 13:1 to 1:1.
