A series of amphoteric surfactants was prepared by the reaction of 1,3-propanesultone with fat derived primary amines, N-methylalkylamines, N,N-dimethylalkylamines, and N-acyl-N′,N′-dimethyl-1,3-propanediamines. Both mono- and disulfopropylated derivatives of the primary amines were synthesized. All compounds were found to be excellent lime soap dispersing agents. The quaternary sulfobetaines were found to possess the best detergency properties both by themselves and when formulated with tallow soap with or without sodium silicate builder. The detergency performance of such formulations is ca. the same as that of a commercial phosphate-built detergent. |
