  • Patent number: 4931203
    Abstract: A free flowing, stable, water-soluble, powdered automatic dishwashing detergent with superior solubility, handling and storage characteristics is provided. The compositions comprises an inorganic polyphosphate carrier onto which is absorbed a nonionic detergent. The "loaded" carrier is mixed with powdered silicate and the other usual adjuvants such as bleach, pigment, etc. High levels of detergent are possible without adversely affecting the aforementioned advantages and superior characteristics.

  • Patent number: 4764291
    Abstract: Polyamides of trialkylacetic acids and polyamines are new compounds which are of an oily nature at washing temperatures in the 10.degree. to 90.degree. C. range, are capable of being adsorbed from wash and rinse waters by fibrous material, such as laundry, of synthetic fabrics, e.g., polyesters, which laundry is susceptible to being electrostatically charged, and decrease any electrostatic charge or inhibit accumulation thereof on such materials. Such polyamides, e.g., those of neodecanoic acid and an alkylene polyoxyalkylene triamine, such as that which is sold by Exxon Chemical Americas under the name Jeffamine.RTM. T-403, can be incorporated in detergent compositions, in compositions for addition to rinse waters and in compositions for application to laundry in a laundry dryer.

  • Patent number: 4715970
    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.

  • Patent number: 4715862
    Abstract: A wash cycle fabric conditioning composition, which makes laundry washed in an 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 N-higher alkyl neoalkanamide or an antistatic N-higher alkenyl neoalkanamide, or a mixture thereof, and a detergent builder, such as a water soluble builder salt or a zeolite, or a mixture thereof, as a carrier, or an aqueous medium containing a nonionic surface active agent. Specifically preferred neoalkanamides of the type described are N-higher alkyl neodecanamides, such as tallowalkyl neodecanamide. In some instances, bentonite may be included in the particulate compositions to soften the fabrics that are washed, and tertiary amines may be formulated into the liquid compositions to increase fabric softening action.

  • Patent number: 4714559
    Abstract: Polyamides of trialkylacetic acids and polyamines are new compounds which are of an oily nature at washing temperatures in the 10.degree. to 90.degree. C. range, are capable of being adsorbed from wash and rinse waters by fibrous material, such as laundry, of synthetic fabrics, e.g., polyesters, which laundry is susceptible to being electrostatically charged, and decrease any electrostatic charge or inhibit accumulation thereof on such materials. Such polyamides, e.g., those of neodecanoic acid and ethylene diamine or hexamethylene diamine, N,N'-ethylene-bis-neodecanoamide and N,N'-hexamethylene-bis-neodecanoamide, respectively, can be incorporated in detergent compositions, in compositions for addition to rinse waters and in compositions for application to laundry in a laundry dryer.

  • Patent number: 4682982
    Abstract: N-higher alk(en)yl neoalkanamides are new compounds which unlike many other amides, are oily at washing temperatures, in the 10.degree. to 90.degree. C. range, and are capable of being adsorbed from wash and rinse waters by fibrous materials, such as laundry of synthetic, e.g., polyester, fabrics, which laundry is susceptible to being electrostatically charged, and decrease any electrostatic charge or inhibit accumulation thereof on such materials. Such neoalkanamides, e.g., N-coco-alkyl neodecanamide, can be incorporated in detergent compositions and in compositions for addition to laundry rinse waters, and in some instances it may be desirable for bentonite powder or agglomerate to also be included in such compositions to contribute fabric softening and other useful physical properties. Washing and rinsing operations are described in which N-higher alk(en)yl neoalkanamide is present in the waters, with and without supplementing small proportions of quaternary ammonium salt.

  • Patent number: 4676915
    Abstract: An antistatic composition, useful for addition to laundry detergents, shampoos and other preparations for treating fibrous and other materials to diminish tendencies thereof to accumulate electrostatic charges, comprises an amide of trialkylacetic acid and/or an amide of isostearic acid, and a quaternary ammonium salt in a certain range of proportions, with the proportion of amide(s) being greater than that of quaternary ammonium salt.
