  • Patent number: 5929014
    Abstract: A storable, substantially water-free flowable surfactant mixture containing 40% by weight to 70% by weight of a nonionic surfactant of the formula R.sup.1 --(OC.sub.2 H.sub.4).sub.n --OH wherein R.sup.1 is an alkyl or alkenyl group containing 10 to 20 carbon atoms and an average degree of ethoxylation n of from 1 to 8; 20% by weight to 50% by weight of a nonionic surfactant, liquid at room temperature, of the formula: R.sup.2 --(OC.sub.2 H.sub.4).sub.r --(OC.sub.3 H.sub.6).sub.p --OH wherein R.sup.2 is an alkyl or alkenyl group containing 10 to 20 carbon atoms, an average degree of ethoxylation r of from 2 to 8 and an average degree of propoxylation p of from 1 to 6; and 1% by weight to 10% by weight of a C.sub.10 to C.sub.22 carboxylic acid and/or alkali metal salts thereof. The flowable surfactant mixture provides a base for forming a pseudo-plastic detergent formulation.

  • 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.
