Biocidal composition for leather tanning comprising 2-(thiocyanomethylthio) benzothiazole

Abstract

The invention relates to a concentrated solution of TCMTB for the preparation of an emulsion of TCMTB. The concentrated solution comprises (i)2 (thiocyanomethylthio)-benzothiazole, (ii) an ester of a C6-C20 fatty acid derived from vegetable oil or a blend of such esters of C6-C20 fatty acids, (iii) a surfactant or blend of surfactants, (iv) Optionally a further biocide, and (v) optionally a hydrocarbon solvent. The concentrated solution can be diluted with water and the diluted preparation can be used for the preservation of leather during the tanning process. The biocidal compositions according to the invention can be also applied to protect wood, paper, paperboard, cellulose pulp and cellulose products, preventing the growth of fungi on their surfaces or preventing the formation of slimes on materials, equipment and structures used in industrial processes.
