  • Patent number: 7576048
    Abstract: Aqueous liquid laundry detergent compositions useful for cleaning fabrics wherein the compositions contain from about 0.05% to about 0.4%, by weight of the composition, of a cationic hydroxyethyl cellulose polymer having a degree of substitution of the cationic charge of from about 0.01 to about 0.20; from about 5% to about 30%, by weight of the composition, of a surfactant comprising at least one anionic surfactant and at least one nonionic surfactant; and from about 2% to about 15%, by weight of the composition, of fatty acid. Use of such aqueous liquid laundry detergent compositions for handwashing delicate fabrics. Use of such aqueous liquid laundry detergent compositions for machine washing of delicate fabrics, wherein the machine washing occurs at a delicate machine setting.

  • Patent number: 7294611
    Abstract: The invention is directed to a structured liquid fabric treatment composition comprising as added components one or more silicone-based cationic fabric care ingredients preferably selected from the group consisting of cationic silicone polymers comprising one or more polysiloxane units and one or more quaternary nitrogen units; a structuring system comprising a structuring agent, a nonionic emulsifier and an anionic emulsifier; a cationic scavenging agent for the anionic emulsifier and a liquid carrier.

  • Publication number: 20040200005
    Abstract: The invention is directed to structuring systems suitable for incorporation into liquid fabric treatment compositions. Such structuring systems comprise, as added components, (A) a non-polymeric, crystalline, hydroxyl-containing structuring agent, which can crystallize to form a thread-like structuring network throughout liquid matrices; (B) a nonionic emulsifier; (C) an anionic emulsifier; and (D) a liquid carrier. The anionic emulsifier is present in such structuring systems, at concentrations from 0.1% to 8.0% by weight of the structuring system.

  • Patent number: 5719116
    Abstract: A process for making a concentrated liquid detergent composition comprising the steps of: i) mixing succinic anhydride, water and an alkaline catalyst, wherein the ratio of succinic anhydride to water is at least 4:1; ii) allowing an exothermic hydrolysis reaction to take place in a buffer tank, and iii) mixing the resulting highly active, partly neutralised succinic acid with other detergent ingredients.
