Obtaining and Characterization of an Ecologic Wax Emulsions
for Finishing Natural Leathers and Furs

Abstract:

The prepared wax emulsions contain natural ingredients - beeswax and lanolin, as well as stearin, obtained by cleavage of natural fats. They have homogeneous appearance and a particle size ranging between 4 and 8 µm. The mixture of waxes in the aqueous medium was emulsified in the presence of a fully biodegradable non-ionic emulsifier - lauryl alcohol ethoxylated with 7 moles of ethylene oxide. FT-IR spectrum of the film obtained from the prepared emulsions contain bands of all components and the broadband at about 3385 cm-1 due to hydrogen bonds formed by the water left in the film. Used in the final dressings of natural nappalan leather, it gives finishing films a waxy feel and better resistance to scratches and water. Keywords: ecologic wax emulsions, finishing natural leather and fur, FT-IR spectrometry, optical microscopy
