(Distilled water is preferred, but not essential) (If desired, you can prepare solutions of your lab soap and a household soap.) Prepare a detergent solution by dissolving about 1 g your laboratory made detergent in 60 mL (4 The surface plasticity of sodium myristate solutions. 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. 1. Acid-refined tall-oil was separated into resin acid and fatty acids of approximately 94% purity, made into soaps, and compared with those made from oleic acid and rosin. The tall-oil fatty-acid soap shows some points of inferiority to sodium oleate, as might reasonably be expected because of its greater unsaturation. A qualitative explanation for the observed results is based upon an analogy to high polymer/solvent systems. Ind., early issue. B-1. Acid-refined tall-oil was separated into resin acid and fatty acids of approximately 94% purity, made into soaps, and compared with those made from oleic acid and rosin. CAS I. Chem.25, 162–165 (1933). 266 PHYSICAL PROPERTIES OF SOAP/SOLVENT SYSTEMS 267 Critical solution temperatures were determined according to the arbitrary technique of Tughan and Pink (7). the chemical & physical properties (including solubility in various media) of sodium stearate are reviewed.

Snell, F. D., and Reich, I., Journ. Tall-oil resin-acid soap and rosin soap are roughly comparable in dispersing power and lowering of surface tension and interfacial tension. Table 2. Snell, F.

The Rôle of Surface-Active Constituents Involved in the Foaming of Milk and Certain Milk products. In addition, the gel/jelly-sol transition temperatures for aluminum dilaurate/solvent systems have been shown to be an approximately linear function of solvent solubility parameter. The lowest critical solution temperatures for zinc and lead stearates occur in solvents having a solubility parameter of 8.9. Snell, Foster Dee, Ind. El-Rafey, G.A.
