International Classification:

C10M 132

US Classification:

252 347

Abstract:

An oil composition for use on bowling lanes is disclosed in which an organic cationic compound such as a quaternary ammonium compound or a pseudo cationic compound is distributed substantially homogenously throughout an oil component. The resulting composition exhibits a high resistance to carry-down when bowling balls are repeatedly rolled over the oiled portion of the lane.

Abstract:

An amphoteric surfactant system which, in use, is nontoxic to marine or aquatic life, and which contains as amphoteric surfactant at least one amido betaine of a specified class. Multipurpose detergent systems based upon such betaine and incorporating detergent builders and other adjuncts, all selected to be similarly nontoxic. Advantageously, the detergency builder is sodium hydroxide or a suitable sodium salt such as the carbonate, sesquicarbonate, tripolyphosphate, or other. Also advantageously there is incorporated a chelating agent which is advantageously a sodium salt or compound such as the sodium salt of EDTA; and other adjuncts, such as a soil-suspending agent or optical brightener, are also useful additives. A particular advantage of the composition according to this invention is that it provides washing effluents which are substantially nontoxic to marine or aquatic life, other than microorganisms. Also, there is provided a method for producing such nontoxic washing or detersive aqueous effluent or waste liquid that comprises washing a soiled material with water and a detergent composition comprising an amido betaine as described above and a detergent builder, advantageously comprising also a chelating agent and, if desired, an optical brightener or the like, and separating off the aqueous effluent.
