Definitions

  • German Offenlegungsschrift 1,494,847 it has already been proposed to improve pulverulent, storage-stable decalcifying agents based on an adduct of urea and phosphoric acid by adding 3 to 60% by weight of maleic anhydride. This is intended to dissolve the incrustations that usually consist of lime and rust more quickly and completely.
  • 0.1 to 3% by weight of cationic, anionic or nonionic surfactants could also be added to these agents.
  • corrosion inhibitors has also been recommended, although the agents themselves, in contrast to known acid decalcifying agents, have only a very low tendency to corrode and should have a gentle effect on the fibers.
  • 2% coconut fatty alcohol sulfate was dissolved in a mixture of 40% by weight phosphoric acid (100%) and 8% by weight water, and 10% by weight powdered maleic anhydride was added to it. This was followed by the addition of 27% by weight of urea. After the mixture had cooled and solidified, 11% by weight of anhydrous sodium sulfate and 2% by weight of finely divided silica were added to improve the powder properties.
  • the present invention thus relates to a process for producing a homogeneous, liquid laundry treatment agent, which is characterized in that maleic acid is dissolved in warm water, phosphoric acid is added, urea is stirred into this solution and then non-ionic surfactants are added with further stirring.
  • the present invention relates in particular to a process for producing a clear, homogeneous, liquid laundry treatment agent, which is characterized in that 5 to 15, preferably 5 to 10% by weight of maleic acid in 20 to 50, preferably 25 to 45% by weight Dissolves water heated to 40 to 60 ° C, adds 20 to 45, preferably 25 to 38% by weight phosphoric acid (100%), stirs 10 to 25, preferably 15 to 23% by weight urea into this solution and then 1 to 10, preferably 1.5 to 8 wt .-% of a nonionic surfactant, preferably a mixture of several nonionic surfactants.
  • a nonionic surfactant preferably a mixture of several nonionic surfactants.
  • a further, water-free corrosion inhibitor for example alkyl monophosphonic acid having 6 to 10, preferably 8 to 10, carbon atoms in the molecule can also be added to the agents according to the invention.
  • Suitable nonionic surfactants are both alkylphenols with 8 to 18, preferably 9 to 15, carbon atoms in the alkyl radical and alkanols or alkenols with 12 to 22, preferably 12 to 18, carbon atoms which have reacted 2 to 20, preferably 5 to 10, moles of ethylene oxide, and their mixtures into consideration.
  • solvents in the form of low molecular weight aliphatic alcohols such as methanol, ethanol, isopropanol or butanol and / or optionally also solubilizers such as low molecular weight alkylbenzenesulfonates.
  • solvents in the form of low molecular weight aliphatic alcohols such as methanol, ethanol, isopropanol or butanol and / or optionally also solubilizers such as low molecular weight alkylbenzenesulfonates.
  • Their amounts can be 0.5 to 5% by weight.
