Abstract

The characteristics of emulsions used in a tannery for leather greasing are presented in this study. Emulsions have been prepared from five commercial greasing [fatliquor] products as 10% emulsions which were tested in the pH range from 4 to 8.

Mean particle size, fraction number and dispersion coefficients of tested systems are presented. Based on the results obtained it was found that samples with emulsions containing lanolin and samples with emulsions containing mixtures of synthetic and natural oils showed the best stability.
