Two-step analytical procedure for the characterization and quantification of metal soaps and resinates in paint samples

open access: yesHeritage Science, 2018
Metal soaps and resinates are known to be spontaneously formed in artistic paintings, as a product of the reaction between aliphatic and terpenoid acids released by hydrolysis and oxidation of the organic media and certain cations contained in some ...

Thermal stability of some metal-palmitate soaps which find various industrial applications

open access: yesGrasas y Aceites, 2001
The soaps of alkaline earth's and transition elements and closed ‘d’ orbitals were prepared by the double decomposition method by the reaction between metallic salts and sodium palmitate. The thermal stability of these soaps was studied in order to throw

ON METALLIC SOAPS

open access: yesJournal of Japan Cosmetic Chemists Association, 1966
Metallic soaps have many varieties and many applications.Aluminum soap shows special properties, and its synthetic procedure and application differs from other metallic soaps.When we want to use the dispersions of metallic soap in nonaqueous liquids, we must observe the effects of cation or anion variation on structure and solvent composition.

Studies in Heavy Metal Soaps. Synthesis or Chloride Soaps or Aluminium

open access: yes, 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.
