  • Patent number: 5451336
    Abstract: A process for preparing a storage-stable and free-flowing concentrated water-based liquid detergent containing 15 to 35% by weight of anionic surfactant, 20 to 35% by weight of nonionic surfactant, and from 5 to 20% by weight of alcohol. A dilute sodium hydroxide solution is heated to 70.degree. to 85.degree. C. to which is added a fatty acid and the alcohol. The mixture is stirred at 350 to 500 r.p.m. for 3 to 10 minutes. The anionic surfactant and nonionic surfactant are added to the mixture and stirred at 150 to 350 r.p.m.

  • Patent number: 4963158
    Abstract: Soiled textile articles are washed by the addition of a determined amount of a detergent concentrate containing surfactants to the textile articles to be cleaned while the textiles are dry or only damp. The aqueous washing liquor is formed by the gradual addition of water to the textile articles while they are rotated. At room temperature, the detergent concentrate is to a substantial extent a paste-to dough-like substance, stable in form, and is applied to the textile articles in such an amount that the major portion of the surfactants together with further detergent constituents, if desired, are applied to the textiles or on an article of textile provided with markings for the correct detergent dose, as a dosing aid.

  • Patent number: 4913829
    Abstract: Fabric softeners for the treatment of fabrics after washing contain as active constituents a combination of one or more sulfonic acids or phosphonic acids and amines or quaternary ammonium compounds thereof bearing a long alkyl or alkenyl radical.

  • Patent number: 4851140
    Abstract: A liquid fabric treatment composition comprising aliphatic hydrocarbon, fatty acid, fatty acid salt, fatty acid ester, and a fatty acid condensate of a natural fat and hydroxyalkyl polyamine in aqueous medium. The composition provides washed fabrics treated therewith with softness and smoothness which, particularly, makes large articles of washing easier to iron by hand ironing or by rotary ironing.

  • Patent number: 4820436
    Abstract: Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.
