The tall-oil fatty-acid soap shows some points of inferiority to sodium oleate, as might reasonably be expected because of its greater unsaturation. 2. DOI: 10.1016/0095-8522(54)90023-9.

El-Rafey, G.A. Each type of soap has a specific proprietary composition and different physical properties (density, hardness, abrasiveness, color, etc.) Physical Properties Test From the product prepared (soap) it has been observed that it have the following physical properties as shown in the table below. Soap bubbles are physical examples of the complex mathematical problem of minimal surface.They will assume the shape of least surface area possible containing a given volume. - 51.210.42.185. volume 27, pages73–74(1950)Cite this article. Certain solubility-linked physical properties of soap/solvent systems have been shown to be functions of the solubility parameter of the solvent. Prepare a detergent solution by dissolving about 1 g your laboratory made detergent in 60 mL (4 (Distilled water is preferred, but not essential) (If desired, you can prepare solutions of your lab soap and a household soap.) the chemical & physical properties (including solubility in various media) of sodium stearate are reviewed.
