Abstract
Abstract A wash cycle additive antistatic composition, which, when added to a wash water in a washing machine, makes laundry washed in such automatic washing machine and dried in an automatic laundry dryer resistant to the accumulation of static charges thereon, and which may be in particulate, liquid or other suitable form, comprises an antistatic polyamide of trialkylacetic acid and polyamine, wherein the alkyls of the trialkylacetic acid moiety are of 1 to 10 carbon atoms each and the polyamine moiety contains from 2 to 5 amino groups, and a particulate carrier or liquid medium for the polyamide, which is a detergent builder or filler, or is an aqueous medium containing a nonionic surface active agent.
