PRODUCTION OF A SURFACTANT BASED ON BOVINE BONE COLLAGEN HYDROLYSATE AND EVALUATION OF ITS PHYSICOCHEMICAL PROPERTIES

This article describes a method for producing a surfactant through the alkaline hydrolysis of collagen extracted from bovine bones and presents some of the physicochemical properties of the resulting preparation. The functional groups of the collagen hydrolysate were characterized using infrared (IR) spectroscopy. The surface tension of the preparation at different temperatures was comparatively evaluated against surfactants based on distillery stillage residue and fusel oil, as well as water. The results demonstrate that the collagen hydrolysate-based preparation significantly reduces the surface tension of water.
