Definitions

  • non-ionic detergent substances especially those based on polyglycol ethers, have a low-foaming power.
  • the foam-inhibting properties of these compounds are often not sufficient adequate to reduce the foam formation of such washing and cleaning agents which contain highly foaming tensides of the sulfate or sulfonate type.
  • the effect of these fatty acids is, however, limited to tensides of the sulfonate type and depends, in addition, upon the hardness of the water used for the preparation of the cleaning solution.
  • the silicones widely used as foam inhibitors are less suitable for washing and cleansing agents since they have a hydrophobizing effect on the cleaned objects and can be removed only with difiiculty from the substrate.
  • An object of the present invention is to provide washing, rinsing and cleaning agents which, compared with the known agents, have an improved anti-foaming action independent of the nature and composition of the foaming compounds as well as of the hardness of the water, have no negative effect on the cleaning action of the agents or on the usefulness of the cleaned substrate, are effective in small concentrations, and overcome the disadvantages of the prior art.
  • Another object of the invention is to provide low-foamice ing rinsing, washing and cleaning compositions comprising (A) from to 99.9% by weight of at least one active compound selected from the group consisting of cleaning compounds and complexing compounds, and (B) from 0.1% to 10% by weight of a foam inhibitor selected from the group consisting of (1) at least one foam-inhibiting isocyanurate of the formula wherein R R and R are members having '8 to 30 carbon atoms selected from the group consisting of alkyl, alkenyl, alkylcycloalkyl and alkylphenyl and (2) mixtures of said at least one foam-inhibiting isocyanurate with at least one alkylated urea of the formula wherein R and R are members having 8 to 30 carbon atoms selected from the group consisting of alkyl, alkenyl, alkylcycloalkyl and alkylphenyl, and R and R are members selected from the group consisting of hydrogen and hydrocarbonyls having from 1 to 30 carbon
  • the invention therefore, comprises low-foaming Washing, rinsing and cleaning agents which are characterized in that they contain (a) from 90% to 99.9% of at least one compound having a cleaning or complexing action and (b) from 0.1% to 10% by weight of at least one foam-inhibiting isocyanurate of the formula wherein R R and R are identical or different aliphatic, cycloaliphatic or alkylaromatic hydrocarbon radicals having from 8 to 30 carbon atoms.
  • the hydrocarbon radicals, R R and R can be straightchain or branched, saturated or unsaturated and contain preferably 12 to 24 carbon atoms.
  • suitable radicals are alkyls and alkenyls such as lauryl, myristyl, cetyl, stearyl, arachyl, behenyl, lignoceryl, palmitoleyl, and oleyl, also such which derive from the hydrocarbon radicals occurring in natural fats, such as coconut, tallow, rape oil, palm kernel, soybean oil, cotton-seed oil, peanut oil, or olive oil fatty acids or from their hydrogenation products.
  • hydrocarbon radicals obtainable from paraffin hydrocarbons or synthetically, for example, by ethylene or propylene polymerization or oxosynthesis are suitable.
  • alkylcycloalkyl and alkylphenyl radicals are suitable such as dodecylcyclohexyl and dodecylphenyl.
  • the preparation of the isocyanurates can be carried out in any way, for instance, by reaction of alkali metal cyanates with halogen hydrocarbons or alkylsulfates.
  • the radicals R and R or R and R can be identical or different, straight-chain or branched, saturated or unsaturated, or also cycloaliphatic or alkylaromatic.
  • dialkylurea or dialkenylurea compounds are used in which R; and R represent straight-chain, saturated or singly unsaturated hydrocarbon radicals with 12 to 24 carbon atoms and the radicals R and R hydrogen.
  • the radicals R and R can be derived from fatty acids of natural or synthetic origin. Examples are lauryl, myristyl, cetyl, stearyl, arachyl, behenyl, lignoceryl, palmitoleyl, and oleyl, also their mixtures, such as they are present, e.g., in coconut, tallow, rape oil, palm kernel oil, soybean oil, cottonseed oil, tall oil, peanut oil, or fish oil fatty acids or their hydrogenation products.
  • the radicals can also be derived from paraffin hydrocarbons, olefin polymerizates, such as polyethylene, polypropylene, and polybutylene as well as from compounds obtained by oxo-synthesis.
  • alkylcycloalkyl and alkylphenyl radicals are suitable such as dodecylcyclohexyl and dodecylphenyl.
  • the rinsing, washing and cleaning compositions of the invention are low-foaming rinsing, washing and cleaning compositions comprising (A) from 90% to 99.9% by weight of at least one active compound selected from the group consisting of cleaning compounds and complexing compounds, and (B) from 0.1% to by weight of a foam inhibitor selected from the group consisting of (l) at least one foam-inhibiting isocyanurate of the formula wherein R R and R, are members having 8 to 30 carbon atoms selected from the group consisting of alkyl, alkenyl, alkylcycloalkyl and alkylphenyl and (2) mixtures of said at least one foam-inhibiting isocyanurate with at least one alkylated urea of the formula wherein R and R are members having 8 to 30 carbon atoms selected from the group consisting of alkyl, alkenyl, alkylcycloalkyl and alkylphenyl, and R and R are members selected from the group consisting of hydrogen and hydrocarbon
  • dialkyl or tetraal-kylureas can be carried out in a manner, in itself known, for instance by alkylation of urea with primary or secondary alkylhalides, dialkylsulfates, or monoor dialkylamines.
  • the urea derivatives can be admixed with the trialkyl iso cyanurates, or together with them added to the cleansing agents.
  • mixtures of trialkyl isocyanurates and dialkylureas are used as they are directly obtainable by reaction of urea with monoalkylamines in the mol ratio 1:2 or by reaction of alkylhalides with potassium cyanate in polar aprotic solvents.
  • the reaction of urea with alkylamines can be carried out by heating the mixture for several hours at temperatures between 150 and 250 0., preferably 180 to .200" C.
  • Potassium cyanate and alkylhalides can, for instance, be reacted in dimethyl formamide by heating for several hours at temperatures from 100 to 150 C.
  • the weight ratio of trialkyl isocyanurates to dialkylureas is in a range from 100:1 to 1:100, preferably from 50:1 to 1:20.
  • the mixtures obtainable by the reaction of alkylamines and urea at elevated temperatures may optionally contain also further condensation products, such as alkylated biurets and triurets. These side products, present in low amounts, also have foam inhibiting properties and can support the tiralkyl isocyanurates and dialkylureas in their effect. It has been found that trialkyl isocyanurates, acting as foam inhibitors, or their mixtures with dialkylureas in which the alkyl radicals have 10 to 14 carbon atoms have their optimum anti-foaming effect in the temperature range of from 20 C. to 60 C. If the alkyl groups have 16 and more, particularly 18 to 22 carbon atoms, the maximum foam inhibition is altered to the range of from 60 C. to 100 C. By appropriate selection or combination of foam inhibitors with different alkyl groups, the foaming behavior of the washing, cleansing, and softening agents can, therefore, be directed arbitrarily and be adjusted to the various requirements.
  • foam inhibitors to be used depend upon the amount of foaming or detergent substance present in the final composition and/ or on the substrate to be cleaned as well as upon the magnitude of the desired effect.
  • concentrations applied extend from 0.1% to 10%, preferably from 0.2% to 5% by weight, based on the solid composition. It is, of course, possible to work with still larger amounts, for instance, up to 25% by weight and more. This, however, is not required in the practice.
  • the foam inhibitors can be mixed with the other washing, cleansing, and descaling agents in a conventional manner and can be processed together with them, for example, spray dried or granulated, or they can be converted by other known processes to solid, liquid or pasty mixtures.
