摘要： A particulate fabric softening composition and a particulate fabric softening detergent composition are described, both of which include bentonite powder agglomerated into larger particulate bead or granule form with a normally solid co-melt of a pentaerythritol compound (PEC), such as pentaerythritol ditallowate (PEDT), and a nonionic surfactant, such as a condensation product of a mole of a C.sub.12-15 fatty alcohol with seven moles of ethylene oxide. The fabric softening composition described may be added to wash (or rinse water) but preferably is incorporated in a particulate built synthetic organic anionic and/or nonionic detergent composition to produce a fabric softening detergent composition. The invented detergent compositions are especially suitable for washing laundry in "cold" water, such as water at 40.degree. C. or thereabout, in which the nonionic surfactant increases the dispersibility of the PEC, improves fabric softening activity thereof, in conjunction with the bentonite, and also prevents excessive whitening or chalking of dark colored laundry by the particulate fabric softening composition. These improved results have been attributed to the nonionic surfactant lowering the co-melt's melting point to about 40.degree. C. or lower, at which temperature the softening composition disperses satisfactorily in the wash water. Additional advantages of the invention are a bonus effect of the nonionic surfactant in increasing detergency of the detergent composition and wash water, and in allowing a decrease in PEC content of the softening and detergent compositions without loss of softening effect.

摘要： 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 softer and static-free, whether such washing is with American or European washing machines and in accordance with such practices. Unexpected improvements in soil removal, as measured visually and by reflectometer, are noted after the washing of laundry that had been stained with oily soils, and the washed laundry is softer.Also described in a process for manufacturing detergent compositions comprising synthetic anionic organic detergent, zeolite, tripolyphosphate and the mentioned imidazoline, in which an aqueous crutcher mix is made, to which the zeolite is added before the tripolyphosphate, and the imidazoline is added immediately after the tripolyphosphate, thereby avoiding undesirable reaction of the imidazoline with the zeolite, which reaction has a negative effect on antistatic and fabric softening properties of the resulting product. The product is obtained in particulate solid form by spray drying of the crutcher mix in conventional manner. Various other active and adjuvant components of the detergent composition may be post-added with the spray dried beads or may be incorporated in the crutcher mix.
