Definitions

  • a low-foaming detergent composition containing an anionic detergent, a builder salt and either a C fatty acid soap, a foam-depressant nonionic detergent or a mixture of the soap and the nonionic detergent is improved by the addition of 0.5 to 10% by weight of the composi tion of certain diethers of polyalkylene oxide diols that have a high-temperature foam depressant action.
  • the composition can also contain a perborate bleach.
  • the invention relates to detergent compositions. More particularly the invention relates to built detergent compositions which are suitable for use in drum-type washing machines as well as in other types of washing machines.
  • An ideal detergent composition for this purpose would be one which is low-foaming to very low foaming at high temperatures, i.e. above about 80 C., and has acceptable foaming characteristics at temperatures of up to about 60 C.
  • Such a detergent composition would be very suitable for use in drum-type washing machines and in any other type of washing machine, because in spite of its reasonable foaming capacity overfoaming at higher temperatures would be avoided.
  • the present invention provides a process of preparing such detergent compositions.
  • Foam suppression has also been obtained by the use of so-called mixed-active detergent compositions.
  • Such compositions usually contain about 5 to 30% by weight of anionic detergent, such as alkylbenzene snlphonate, alkyl sulphate, fatty alcohol sulphate and the like, as well as builder salt.
  • the compositions are called mixed-active since they contain a minor proportion, about 1 to preferably 1 to 5% by weight of the composition, of soap, foam depressant nonionic detergent or a mixture of soap and the nonionic detergent.
  • soap is meant an alkali metal or ammonium salt of a C fatty acid.
  • Suitable nonionic detergents include the alkylene oxide condensation products or alkyl alcohols, of alkyl phenols and of polyoxypropylene and of other organic hydrophobic compounds.
  • Detergent compositions of this type can contain an oxygen-liberating bleaching agent, such as perborate, further silicate and small amounts of optical brighteners and soilsuspending agents, such as carboxymethylcellulose.
  • the builder salt can be, for example, a salt of an organic acid such as nitrilotriacetic acid, ethane-l-hydroxy-1,1-diphosphonic acid or a polymeric carboxylic acid, or a salt of a polyphosphate such as sodium tripolyphosphate.
  • the weight ratio of anionic detergent to builder salt is between 1:1 and 1:5. By weight of the composition the amount of perborate will be between 0 and 30% and of silicate between 0 and 15%.
  • the foam depressant action provided by the soap component in such detergent compositions is stronger according as the soap has a higher content of saturated molecules with at least 20 carbon atoms, such as soap from hardened marine oils or certain vegetable oils, it was established that these soaps still provide a distinct foam-- suppressing effect at low and medium temperatures, which in many respects is undesirable.
  • R and R are alkyl groups having a total number of 2 to 30 carbon atoms, R and R are each H or CH and n is variable over a wide range.
  • These compounds are thus diethers of polyalkylene oxide diols, the polyalkylene oxide groups of which are naturally not restricted to those consisting of equal alkylene oxides but may also be a mixed polymer of different alkylene oxides.
  • the invention provides a detergent composition containing an organic anionic detergent, as well as soap and/ or a nonionic detergent, characterised in that a compound is incorporated which is a diether of a polyalkylene oxide diol of the following general formula:
  • the lather controlling effect of the diethers meant by the present invention increases with their molecular weight and reaches an optimum value.
  • those compounds are very effective in which n is within the range from 2 to about 40, particularly, if the functional groups in the molecule are properly selected.
  • a selection of the suitable functional groups within the specified ranges can be easily made by determining the Hydrophylic-Lipophylic Balance Value of the compound, which value should lie within the range of approximately 1.0 to approximately 4.0.
  • Preferred compounds are those of which the polyalkylene oxide group is mainly or completely built up from propylene oxide groups. As such may be men tioned:
  • These compounds include those which are already conimercially available as a number of products under the UCON Lubricant trademark. They are usually prepared by reacting an aliphatic alcohol with alkylene oxide(s) in the presence of an alkaline catalyst, followed by etherification of the hydroxyl groups according to any of the various known methods, as described in US. patent specification No. 2,520,612.
  • diether compounds according to the invention is not restricted to the washing of laundry, but they may also be advantageously applied in any other 4 cleaning process in which it is desired that at elevated temperature far less foam is produced in the low and medium temperature ranges.
  • EXAMPLE 1 The effectiveness of the compounds as high-temperature foam suppressants is shown by the graph in FIG. 1, which was obtained by means of comparative tests made with the following detergent compositions in the dynamic foam meter at concentrations of 5 g./litre and using water having a hardness of 15 DH.
  • the foam height of the relevant detergent compositions on the vertical axis is set against the temperature on the horizontal axis.
  • a built detergent composition with controlled foaming characteristics consisting, by weight, essentially of from 5 to 30% of an anionic non-soap synthetic detergent; from 1 to 10% of an alkali metal soap of fatty acids having from 8 to 25 carbon atoms; 0 to 10% of a nonionic synthetic detergent; 0 to 30% of sodium perborate; 0* to 15% of sodium silicate; and as a foam controlling agent about 0.5 to 10% of a compound of the general formula (l 1'.
  • R and --R are alkyl groups having a total number of 2 to 30 carbon atoms
  • --R' is CH
  • R" is a radical selected from the group consisting of H and CH and n is a number from 2 to 40, the Hydrophylic- Lipophylic Balance Value of the compound being from 1.0 to 4.0.
  • the detergent composition according to claim 2 containing from 1 to 3% of the foam controlling agent.
