Definitions

  • the present application relates to foam-controlled detergents.
  • the present invention now allows the use of WAS substances or their combinations which are optimal in their technical behavior and in terms of cost, without being severely restricted in their choice by their foaming behavior.
  • different foaming behavior is also desirable at different temperatures.
  • the intended purpose can be achieved by adding a mixture of metal soaps to a detergent and alkyl phosphates is added.
  • the desired foam profile can be set by a suitable selection of the components, which have different individual characteristics over the entire temperature range of approx. 20-100 ° C., by the interaction of their mutually influencing properties.
  • the metal soaps which can be used according to the invention are those metal soaps which, up to the maximum temperature at which they are said to still be effective, are not in solution in the washing process due to sufficiently long C chains and avoidance of reversion into their Na salt can go.
  • suitable metal cations include. Ca, Mg, Al, Zn;
  • suitable fatty acids from which the metal soaps are produced are the higher molecular weight (C 12 -C 22 or higher) fatty acids or mixtures thereof, such as stearic acid, palmitic acid and higher fatty acids.
  • a preferred metal soap is calcium stearate.
  • the alkyl phosphates which can be used according to the invention are mono- and / or dialkyl orthophosphates, the alkyl group of which can contain from 12-22 carbon atoms or their Alkyl group can be separated from the P atom by a number of alkylene oxide groups (up to 0).
  • the alkyl phosphates are present as alkali metal salts. Suitable examples are C 16 -C 18 monoalkyl phosphate (sodium salt), such as stearyl monophosphate, mixtures of mono- and distearyl phosphate, mono- and dilauryl ether phosphate, etc.
  • the metal soaps are used in an amount of 0.1 to 3, preferably 0.5 to 15 1.5% by weight of the detergent, and the alkyl phosphates in an amount of 0.05 to 2, preferably 0.2 to 1% by weight.
  • the mixture of metal soaps and alkyl phosphates according to the invention is preferably added to the detergent as a secondary.
  • suitable processes are secondary spraying of metal soaps and alkylphosphates dispersed in nonionic surfactant onto the detergent powder, homogeneous mixing being attempted by various measures (such as ultrasound); Granulation of metal soaps and alkyl phosphates and secondary addition of this granulated mixture to the detergent powder; Encapsulation of dispersions of metal soaps and alkyl phosphates and secondary addition of this encapsulated mixture to the detergent powder; Dusting the metal soaps and alkyl phosphates on the still sticky detergent powder etc.
  • the metal soap and the alkyl phosphate are dispersed in a nonionic surfactant, and this dispersion is sprayed onto the detergent powder secondarily.
  • the invention allows the Use of an optimal WAS in the detergent.
  • these are purely anionogenic substances.
  • anionogenic substances are usually water-soluble alkali metal salts of organic sulfonates or sulfuric acid esters, which have alkyl radicals with about 8 to 22 carbon atoms.
  • Oxidized starch and cellulose derivatives in particular those with dicarboxyl residues, sodium alkenyl (C 10 -C 20 ) succinates, sodium sulfofatty acids, alkali metal carbonates, sodium aluminum silicates, carboxymethyloxysuccinates, nitrilotriacetates etc.
  • the percentages relate to% by weight, based on the weight of the basic batch.
  • Figure 1 shows the foam behavior of these approaches; as can be seen, no foaming occurred over the entire temperature range.
  • Example 2 The same additives as in Example 2 were used, but with a different basic approach. This was of the following composition:
  • FIG. 3 shows the foaming behavior of these batches F (with Na stearate), G (with Ca stearate) and H (with Al stearate).
