A fungicidal composition in the form of an aqueous emulsion is formed from 3- iodo-2-propynyl-N-butylcarbamate (IPBC), 2-(thiocyanomethylthio)benzothiazole (TCMTB), polyoxyethylene triglyceride, polyalkylene glycol ether, xanthan gum and dipropylene glycol. The composition is formed by adding a molten blend of polyoxyethylene triglyceride to a blend of IPBC and TCMTB, and then adding thereto a solution of xanthan gum in dipropylene glycol and water. The composition is particularly suited for the preservation of wet blue hides as obtained in the leather industry, and may also be used in the preservation of organic coatings delivered from aqueous media.

L'invention concerne une composition fongicide qui se présente sous la forme d'émulsion aqueuse à base de 3-iodo-2-propynyle-N-butylecarbamate (IPBC), 2-(thiocyanométhylthio)benzothiazole (TCMTB), triglycéride de polyoxyéthylène, éther de polyalkylène glycol, gomme xanthane et dipropylène glycol. On obtient la composition en ajoutant un mélange fondu de triglycéride de polyoxyéthylène à un mélange d'IPBC et de TCMTB, puis en ajoutant encore à l'ensemble une solution de gomme xanthane dans du dipropylène glycol et de l'eau. La composition se prête particulièrement bien à la conservation des peaux en bleu humide dans l'industrie du cuir, et on peut aussi l'utiliser afin de conserver les revêtements organiques issus des milieux aqueux.
