Definitions

  • the invention relates to the use of an alkali-soluble copolymer as thickener in liquid laundry detergents and a liquid washing or cleaning composition.
  • Transparent viscous liquid detergent compositions are becoming increasingly popular. There is therefore a need for thickeners which have high transparency in the dissolved, d. H. have neutralized state and show no turbidity when incorporated into surfactant-containing formulations.
  • thickeners are desirable which impart a very high viscosity to the thickened medium at rest, and a low viscosity when subjected to high shear forces.
  • alkali-soluble thickeners are associative thickeners.
  • Associative thickeners are water-soluble polymers and have surfactant-like hydrophobic constituents capable of associating with both themselves and with other hydrophobic materials in a hydrophilic, especially aqueous medium, i. to interact.
  • the resulting associative network thickens or gels the medium.
  • the WO 99/65958 describes alkali-soluble thickeners comprising the reaction product of an unsaturated carboxylic acid, a monoethylenically unsaturated monomer and a hydrophobic alkoxylated macromonomer.
  • the monoethylenically unsaturated monomer includes a methyl group; it is preferably methyl acrylate.
  • the WO 2006/016035 relates to the use of a water-soluble acrylic polymer as a thickener in pigmented aqueous formulations.
  • the acrylic polymer consists of an ethylenically unsaturated monomer having a carboxyl function, an ethylenically unsaturated nonionic monomer and an ethylenically unsaturated oxyalkylated monomer terminated with a hydrophobic non-aromatic branched chain of 10 to 24 carbon atoms.
  • One embodiment relates to a polymer in which the ethylenically unsaturated nonionic monomer is composed of ethyl acrylate and butyl acrylate (Example 7).
  • the WO 2009/019225 discloses an associative thickener having copolymerized units of at least one ethylenically unsaturated carboxylic acid, at least one nonionic ethylenically unsaturated surfactant monomer, at least one C 1 -C 2 alkyl methacrylate and at least one C 2 -C 4 alkyl acrylate, wherein the alkyl chain length averaged over the number of alkyl groups of the alkyl acrylate 2.1 to 4.0. Solutions of the associative thickener or its formulations with a high surfactant content are highly transparent and have a high thickening effect with simultaneous high shear thinning.
  • the term "graying” is understood to mean the gray coloration of textiles during washing, which is brought about, inter alia, by a resumption of already detached dirt on the fabric in a finer distribution. Rebuilding is likely triggered by electrostatic forces. The extent of re-drawing depends, among other things, on the type of fabric and soil, the degree of soiling of the fabric, the amount of water in the washing process and the degree of mechanical movement in the washing drum. Components of the detergent itself can cause graying by z. B. deposit on the fabric or promote the recovery of dirt. It is therefore desirable that the thickeners used in liquid detergents cause as little as possible graying of the laundry after the washing process.
  • the invention also relates to a liquid detergent composition containing the above-defined copolymer.
  • thickeners which contain a high proportion of C 1 -C 2 -alkyl methacrylate units, in particular methyl methacrylate units, may deteriorate the light remission of the laundered laundry. A reduced light remission is perceived as graying.
