Definitions

  • the invention relates to color-stabilized nonionic surfactants which contain polyalkylene oxide groups bonded with terminal hydroxyl groups, and to the use of such color-stabilized nonionic surfactants in alkaline washing and cleaning agents.
  • alkaline reacting framework substances such as phosphates, silicates, carbonates and on the other hand also contain caustic alkalis.
  • An essential and necessary component of such cleaning formulations in addition to any other additives such as, in particular, oxidizing and disinfecting agents, are also nonionic surfactants of the known classes of surfactants, the most important of which are: alkylene oxide copolymers and block polymers; alkoxylated ethylene or propylene polyamines or fatty alcohols, the alkylene oxide component consisting either of pure ethylene oxide or pure propylene oxide or both, and in the latter case the polyaddition can be carried out with the alkylene oxide gas mixture or in succession (in block form).
  • the surfactants used are often those which, despite their good cleaning action, produce little foam or even have a foam-suppressing effect, but special problems can also make highly foaming surfactants necessary.
  • discolouration may occur. These mostly brown discolourations are due to chemical reactions between non-ionic surfactant, alkali and oxidizing substances such as atmospheric oxygen or chlorine carriers in the ready-made cleaner itself.
  • the color changes can only be of an external nature without causing a change in the application properties. In the case of commercial products, which preferably end up in the household, an unappealing appearance hinders sales.
  • the interaction between surfactant, alkali and oxidizing agent can go so far that changes in the application properties can be determined. It has been shown that the free hydroxyl groups of the nonionic surfactants are the target for alkali and oxidizing agents.
  • the invention was therefore based on the object of searching for nonionic low-foam surfactants which, with otherwise unchanged application behavior, are stable against the action of strong alkalis and oxidizing agents.
  • these compounds are aliphatic dicarboxylic acids having 4 to 8 carbon atoms, mixtures thereof, their C 1 -C 4 -alkyl esters or their mixtures.
  • the color stabilizers are dissolved in the liquid, nonionic surfactant by stirring, advantageously in the heat.
  • 0.1 to 5% by weight of stabilizer is preferably added. Less than 0.1% by weight and more than 5% by weight mean no additional advantages. Additions of 0.5 to 3% by weight are of particular technical interest.
  • nonionic surfactant is not liquid at room temperature, it is melted and proceeded as described. After the color stabilizer has dissolved in it, let it solidify again.
  • the color-stabilized surfactants according to the invention can therefore be in liquid or solid form.
  • the color-stabilized surfactants are mixed with the other components, in particular the alkaline builder substances mentioned at the outset and optionally other additives such as oxidizing agents, fragrances and colorants and disinfectants, to prepare the cleaning formulations.
  • the non-color-stabilized mixtures there is practically no risk of any discolouration during storage, not even in the heat. It has been shown that the color stabilizers in almost all Ethylene oxide and ethylene oxide / propylene oxide surfactants are effective, ie no time-consuming attempts are necessary to select special surfactants, for example.
  • Cleaner formulations which contain the color-stabilized surfactants according to the invention generally comprise from 70 to 99, preferably 90 to 99% by weight of inorganic alkaline builder and 30 to 1, preferably 10 to 1% by weight, based in each case on the entire formulation Surfactant together.
  • the alkylene oxide adducts were tested in such a way that they were stored at different temperatures for 24 days with and without addition of stabilizer.
