Abstract
A fabric softening and antistatic liquid laundry detergent composition includes synthetic anionic organic detergent, bentonite and higher aliphatic isostearamide antistat in an aqueous medium. The liquid detergent composition preferably contains a builder for the detergent component, such as polyphosphate and/or carbonate. Also within the invention is a process for washing and drying laundry, utilizing the described liquid detergent in the washing operation, whcih produces laundry that is soft and static-free or of low electrostatic charge despite having been subjected to a tumble drying process or similar static charging drying process, which normally causes laundry of similar fabrics to become electrostatically charged, resulting in objectionable 'static cling'. Also described is a 'softstat' product which comprises bentonite fabric softener and N-isostearamide antistat in an aqueous medium, which is intended for addition to liquid detergent compositions or to wash waters to make them fabric softening and antistatic, so that laundry washed with them will be soft to the touch and free of static cling.
