Definitions

  • the invention relates in a first embodiment to a detergent which contains conventional ingredients such as surfactants, builder substances and nonionic cellulose ethers, this nonionic cellulose ether being selected from the group of methylhydroxy propyl celluloses which contain a proportion of methoxyl Groups of 15 to 35 wt .-% and of hydroxypropoxyl groups of 1 to 15 wt .-%, based on the nonionic cellulose ether. It is preferred that the agents contain methyl hydroxypropyl celluloses which contain 20 to 30% by weight of methoxyl groups and 2 to 10% by weight of hydroxypropoxyl groups, in particular 5 to 8% by weight. %, each based on the nonionic cellulose ether.
  • the detergents contain a nonionic cellulose ether compound which, in addition to methylhydroxypropyl cellulose, contains 6 to 8% by weight of water and 4 to 10% by weight of sodium chloride.
  • the content of the methoxyl groups in the methylhydroxypropyl cellulose is 25 to 30% by weight and preferably 25 to 29% by weight, the content of hydroxypropoxyl groups is 5 to 10% by weight and preferably 5.5 up to 8% by weight.
  • the aqueous solutions of nonionic cellulose ethers must not be too viscous in order to achieve optimal fat and oil washability. It is therefore preferred that the nonionic cellulose ether compound used according to the invention at 20 ° C. in a 2% by weight aqueous solution has a viscosity between 40 and 125 mPas (Brookfield viscometer, 20 ° C., spindle 3, 4 or 5, 20 revolutions per minute), preferably between 45 and 100 mPas and in particular below 100 mPas, for example 45 to 60 mPas.

  • the amount of these non-ionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, in particular not more than half of them.
  • Other suitable surfactants are polyhydroxy fatty acid amides of the formula (I),
  • Usable organic builders are, for example, the polycarboxylic acids preferably used in the form of their sodium salts, such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), provided that such use is not objectionable for ecological reasons. and mixtures of these.
  • Preferred salts are the salts of polycarboxylic acids such as Ci tronic acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of these.

Abstract

L'élimination des graisses et des huiles dans les textiles peut être améliorée par l'utilisation de certains éthers cellulosiques non ioniques. Ces éthers cellulosiques non ioniques sont des méthylhydroxypropylcelluloses contenant une proportion de 15 à 35 % en poids de groupes méthoxyle et de 1 à 15 % en poids de groupes hydroxypropoxyle, rapportés à l'éther cellulosique non ionique.
