Abstract
A detergent composition comprises an equimolecular mixture of a free C3-22 fatty acid and an N-acyl tauride, prepared by reacting with agitation, optionally in the presence of water or an organic solvent, but in the absence of alkaline agents, at least one mole of an anhydride of a C8-22 fatty acid with one mole of a taurine salt having the formula: <FORM:0888323/III/1> where M is an alkali metal, an alkaline earth metal, magnesium, ammonium or substituted ammonium (e.g. triethanolammonium), and X represents hydrogen or a C1-4 alkyl radical, said reaction being conducted at a temperature above the melting point of said fatty acid anhydride. The above composition may be milled into bars, transformed into a mixture of soap and synthetic detergent by saponification with caustic soda or triethanolamine, or converted into a heavy duty granular detergent by admixture with three times its weight of sodium tripolyphosphate.ALSO:Acyl taurides are prepared by reacting with agitation and optionally in the presence of water or an organic solvent at least one mole of an anhydride of a C8-22 fatty acid with one mole of a taurine salt having the formula <FORM:0888323/IV (b)/1> where M is an alkali metal, an alkaline earth metal, magnesium, ammonium or substituted ammonium (e.g. triethanolammonium), and X represents hydrogen or a C1-4 alkyl radical, the reaction taking place in the absence of alkaline agents at a temperature above the melting point of the fatty acid anhydride, the reaction product comprising a mixture of said acyl tauride and free C8-22 fatty acid substantially free from inorganic salts, soaps and unreacted taurine salt, and from which said acyl tauride may be separated by solvent extraction, steam distillation or by precipitation of the free fatty acid as the calcium salt.
