Abstract: Highly pure squalane in which the content of pristane is reduced to 10 wt ppm or less, can be obtained by refining the squalane of animal oil or fat origin through thin film distillation, said highly pure squalane is useful as a raw material for producing cosmetics and medical and pharmaceutical preparations and especially, it is quite effective as a lubricating agent for condoms and as a component of adjuvant composition.

Abstract: In a method of treating clay-containing phosphate rock comprising at least mining the phosphate rock, reducing the phosphate rock to a predetermined size range, adding water to the phosphate rock, and storing the admixture containing at least the phosphate rock and water; the improvement characterized by adding to the admixture an amount effective to control problems associated with the swelling of residual clays of a chemical treatment selected from the class consisting of aliphatic hydroxy acids containing 2-6 carbon atoms, inclusive, of which citric acid and tartaric acid are members; the aliphatic hydroxy acid salts, and effective blends of the aliphatic hydroxy acid or the aliphatic hydroxy acid salts with a strong caustic, or base. The chemical treatment prevents a build up of viscosity such that the admixture remains pumpable even with a concentration of solids in excess of 66 percent by weight.

Abstract: Composition of matter and process effecting a nitrogen-containing material that flows freely and resists caking even on prolonged storage. It can be manufactured to yield a desired percent nitrogen upon analysis characterized by the nitrogen-containing material in its normal manufactured form having on the external surface thereof an amount that is sufficient to reduce its normal caking tendencies an alkene sulfonate containing from 6 to 26 carbon atoms, inclusive. Further reduced caking tendency is effected by including on the surface of the nitrogen-containing material an inert material, such as clay. Also disclosed are the effective and optimum amounts of the respective materials that are added, the amounts being given as an average percent by weight basis.
