Preparation and characterization of Zinc metal soap from shea butter (Vitellaria paradoxa)
Journal of Nigerian Society of Physical Sciences, 2021 Zinc metal soaps are of great importance in the manufacture of personal care products and other industrial applications. Variations in the soaps and their properties are usually due to the type of oil used in the synthesis.

Studies in Heavy Metal Soaps. Synthesis or Chloride Soaps or Aluminium [PDF]
, 1962 Mono and dichloride soaps awl tri-soaps of aluminium have been synthesised by the interaction of anhydrous aluminium chloride and fatty acids in different stoiehiometric ratios in different organic solvents. All chloride maps and tri-soaps give mobile solutions of low viscosity in organic solvents.
