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. 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. Ind.68, 98–100 (1949). Tall-oil resin-acid soap and rosin soap are roughly comparable in dispersing power and lowering of surface tension and interfacial tension.

Certain solubility-linked physical properties of soap/solvent systems have been shown to be functions of the solubility parameter of the solvent. The tall-oil fatty-acid soap shows some points of inferiority to sodium oleate, as might reasonably be expected because of its greater unsaturation.

When grease or oil (non-polar hydrocarbons) are mixed with a soap- water solution, the soap molecules work as a "bridge" between polar water molecules and non-polar oil molecules. Snell, F.

Prepare a 1% soap solution by dissolving about 0.5 g of the soap you just made in 50 mL of deionized water. The purpose of this paper is to present data for several physical-chemical properties of aqueous solutions of numerous commercial soaps and soap­ less detergent materials, and to correlate these with the structure and phase nature of the solid soaps as revealed by investigations with X-ray diffraction and electron microscopy, and to interpret the significance of the results in terms of … The critical solution temperatures were reproducible to within one degree. https://doi.org/10.1007/BF02634390, Over 10 million scientific documents at your fingertips, Not logged in I. Eng. Maximum swelling of lithium and sodium stearate/solvent systems occurs at a solvent solubility parameter of 9.3. Soap vs. oil vs. water: Water alone is not able to penetrate grease or oil because they are of opposite polarity. The Solubility of a Water-insoluble Phenol in Aqueous Solutions of Soap. Part B. A qualitative explanation for the observed results is based upon an analogy to high polymer/solvent systems. The lowest critical solution temperatures for zinc and lead stearates occur in solvents having a solubility parameter of 8.9. Journal of the American Oil Chemists Society - 51.210.42.185.
