Abstract

An antistatic particulate laundry detergent composition comprises synthetic organic detergent, preferably sodium linear dodecylbenzene or sodium linear tridecylbenzene sulfonate, inorganic and/or organic builder for the detergent, preferably sodium tripolyphosphate and/or zeolite builder, and higher alkyl or alkylbenzene hydroxyethyl imidazoline of the formula ##STR1## wherein R is an alkyl or alkylbenzene of 8 to 24 carbon atoms preferably stearyl, which detergent composition is of improved detergency due to the presence therein of the higher alkyl or alkylbenzene hydroxyethyl imidazoline antistat. In preferred detergent compositions of this type bentonite is desirably present for its fabric softening activity, and such activity is improved by the presence of the higher alkyl or alkylbenzene hydroxyethyl imidazoline, which also possesses fabric softening properties. When low phosphorus contents of detergent compositions are not required by law or regulation, contents of zeolites and other non-phosphate builders may be omitted and increased proportions of tripolyphosphate may be employed, instead. The mentioned detergent compositions are useful to wash soiled laundry and to make it…
