Many natural extracts used as cosmetic ingredients are available solutions prepared in high-boiling-point solvents, called carrier such propylene glycol (1,2-propanediol), propanediol (1,3-propanediol) and glycerin. The upstream chemical profiling of these represents a major asset for the industry, because it accelerates product development. A new workflow rapid characterization main metabolite...

Expansion of the biodiesel industry has increased the crude glycerin (CG) supply. Crude glycerin has the potential of replacing corn in ruminant diets because the glycerol can be converted to glucose in the liver of ruminants, providing energy for cellular metabolism. The objective was to evaluate the effects of CG with urea, soybean meal, cottonseed meal, and corn gluten feed, respectively, on...

PREPARATION OF IRON/CARBON MATERIAL FROM BIODIESEL WASTE FOR APPLICATION IN THE REMOVAL ORGANIC CONTAMINANTS. In this work, iron/carbon-based catalysts obtained from biodiesel residues, glycerin, were prepared.The composites prepared by thermal carbonization of the glycerin polymer, in presence iron salt. The materials characterized adsorption/desorption N2, scanning electron microscopy (SEM), ...

In this paper, a new method using the experimental results is proposed to determine rheological characteristics of glycerin purification by vibrocentric machine. The testings are reported based on values unilateral deformation under different process modes. Kelvin-Voight model used for modeling glycerin. A compression device presented studies, which useful simulate technological processing mods...
