Wax composition and its use

Abstract

A wax composition comprises at least three amide waxes A, B, and C, where amide wax A is the reaction product of alkylenediamine with linear fatty acids or with mixtures composed of fatty acids,amide wax B is the reaction product of alkylenediamine with 12-hydroxystearic acid, andamide wax C is the reaction product of alkylenediamine with 12-hydroxystearic acid and with linear fatty acids.
