Abstract

Sodium pentachlorophenate, pentachlorophenol, cresylic acid, beta naphthol and the proprietary products Busan 31, Busan 52, Busan 72, MTC 10 and Preventol have been tested at various concentration levels, added at different stages of processing, for the prevention of natural fungal growth on stored wet blue hides. Sodium pentachlorophenate, pentachlorophenol, cresylic acid and beta naphthol were not very effective in preventing fungal growth for the periods required for overseas delivery of wet blue hides, but could possibly be used at suitable concentrations for the internal short-term holding of wet blue stock in tanneries. The best overall results were obtained with Busan 72 which appeared effective in tannery trials even at concentrations below 0.025% of active ingredient.
