Abstract


The leather industry uses fatty materials to give leather certain characteristics. Neatsfoot oil, a material with variable cost and disponibility, has been used traditionally. Samples of neatsfoot, chicken, fish and rice bran oils are studied in this work. They are evaluated as potential raw materials for leather tanning derivatives, according to their thermal behaviour (Cold Test and DSC) and main fatty acids composition (GC). Some seem adequate for that purpose, while others could be modified through thermal fractionation.
