Preliminary investigations on the effects of naphthalene – based syntan on Accacia niloticatanning material

Abstract

Modification characteristics of Accacia nilotica (Bagaruwa in Hausa) vegetable tanning material with naphthalene–based synthan have been investigated. The initial results showed that blending at a total concentration of 60% W/W Bagaruwa/Syntan ratios produced some synergisms such as improved colour, antimould activity, higher hydrothermal stability and increased rate of penetration of Bagaruwa tannins, hitherto lacking in the individual tanning materials. However, greater synergisms were displayed by the blends at 30:30% W/W and 20:40% W/W Bagaruwa/syntan ratios.


Key words: Syntan, Synergism, Shrinkage Temperature, Blooms, Mould growth.
