  • Patent number: 6482792
    Abstract: A liquid laundry detergent composition of desired viscosity produced by a process comprising dissolving in an aqueous medium a water-soluble builder and a surfactant blend comprising two nonionic surfactants and two anionic surfactants, such as surfactant blend being prepared by partially sulfating and subsequently neutralizing a mixture of two ethoxylated long chain alcohol nonionic surfactants containing different average numbers of ethoxy groups per molecule while employing certain values of the weight ratio of the two nonionic surfactants and the percent conversion of the nonionic surfactants to sulfated anionic surfactants.

  • Patent number: 6034045
    Abstract: A liquid aqueous, laundry detergent composition which has a pH in the range of about 7.0 to about 12.2 and comprises at least one active surfactant; an at least partially neutralized polymer of an .alpha.,.beta.-monoethylenically unsaturated carboxylic acid containing no more than nine carbon atoms which is either (1) a homopolymer of such an unsaturated carboxylic acid, (2) a copolymer of monomers consisting of at least two of such unsaturated carboxylic acids, or (3) a copolymer of monomers consisting of at least 50 mol % of at least one of such unsaturated carboxylic acids with at least one non-carboxylic acid .alpha.,.beta.-monoethylenically unsaturated comonomer containing no more than nine carbon atoms, said polymer having a number average molecular weight of up to about 10,000 and being present in an amount equivalent to at least about 0.025 wt. % of the corresponding unneutralized polymer; and about 30 to about 95 wt. % of water, based on the total weight of the composition.

  • Patent number: 5919745
    Abstract: A liquid aqueous laundry detergent composition having improved cleaning properties and comprising a nonionic surfactant; about 0.25 to about 20 wt. % of an N--C.sub.8 --C.sub.20 alkyl and/or N-unsaturated C.sub.16 -C.sub.18 hydrocarbyl amine of a C.sub.1 -C.sub.7 monocarboxylic acid or salt thereof as an amphoteric surfactant; an alkaline substance in an amount sufficient to cause the wash liquor containing said detergent composition to have a pH of about 8 to about 11 determined ten minutes after the initiation of washing under standard conditions; and about 30 to about 95 wt. % of water, based on the total weight of the composition.
