Abstract

Natural rubber latex is preserved, particularly from bacterial and enzyme degradation, by the addition of one or more zinc dialkyl dithiocarbamate(s) and one or more anionic and/or non-ionic surface active agent(s), and if desired an amount of ammonia less than that required to preserve the latex. Zinc dimethyl dithiocarbamate is preferably used. The surface active agent may be a soap such as ammonium oleate or other reaction product of a fatty acid and an alkali, or sodium salts of sulphate monoesters of a mixture of higher fatty acids consisting chiefly of lauryl and myristyl derivatives, or an aqueous solution of C-cetyl betaine.
