Definitions

  • the present application is aimed at highly concentrated isotropic liquid detergents with surfactant contents of 30% by weight and more, which additionally contain organic, non-surfactant components and have optimized product stability, which is made possible by a specially adapted surfactant system. Also covered are methods for washing textiles using the detergents described and their use.
  • Liquid detergents are well known in the art and have become increasingly popular with consumers in recent years because they offer a number of advantages over solid detergents. These include, among other things, easier dosing, addition and dissolution in the washing liquor. In addition, they are perceived as safer and less aggressive towards textiles and the environment. They have become more and more popular since their market launch, especially for washing colored textiles.
  • polymeric components are increasingly being used in modern liquid detergents. These are often essentially nonionic or anionic polymers with different functionality. Important groups are the so-called soil release polymers, the dye transfer inhibitors (DTIs), anti-redeposition agents and polymeric dispersants.
  • DTIs dye transfer inhibitors
  • a particular challenge is to ensure a stable formulation of the polymers, since the compatibility of the polymeric ingredients of a liquid formulation decreases as the surfactant concentration increases. As a result, cloudiness, sedimentation or even phase separation occur. These particularly affect the aesthetic appearance of the recipe.
  • WO 2013/092049 A1 and WO 2013/092052 describe isotropic liquid detergents comprising surfactants in amounts of over 30% by weight as well as soil release polymers and ethoxylated polyethyleneimines.
  • Liquid detergents contain over 30% by weight of surfactants as well as polyvinylpyrrolidone and a betaine ester polymer.
  • DE102005015328 A1 relates to clear liquid detergents with a surfactant content of over 30% by weight and 3% polyacrylate.
  • DE 2527793 also teaches a liquid agent that has a surfactant content of over 30% by weight and a dirt-repellent polymer.

  • At least one refers to 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In connection with components of the compositions described herein, this information does not refer to the absolute amount of molecules but rather to the type of component. “At least one anionic surfactant” therefore means, for example, one or more different anionic surfactants, i.e. one or more different types of anionic surfactants. Together with quantitative information, the quantitative information refers to the total amount of the corresponding type of component.
  • Isotropic refers to optically isotropic agents, i.e., agents that appear homogeneous and single-phase when viewed with the naked eye.
  • the detergents described herein can be detergents for textiles or natural fibers.
  • the detergents within the scope of the invention also include washing aids which are added to the actual detergent during manual or machine washing of textiles in order to achieve a further effect or to intensify an effect.
  • detergents within the scope of the invention also include textile pre- and post-treatment agents, i.e. those agents with which the item of laundry is brought into contact before the actual laundry, for example to dissolve stubborn dirt, and also those agents that are used in a step following the actual textile washing give the laundry other desirable properties such as a pleasant feel, crease resistance or low static charge.
  • the last-mentioned agents include fabric softeners. In preferred embodiments, however, it is a textile detergent.
  • the liquid detergents have a total surfactant content of 30 to 70% by weight, preferably 35-60% by weight.
  • Total surfactant content refers to the sum of all compounds used with surfactant properties, ie in particular the sum of the amounts of surfactants A, N and N1.

Together with the carbon atom to which they are attached, the two organic (alkylic) residues form a linear or branched alkyl with 1 to 50 carbon atoms.
