2,724,718 11/1955 Stiles et a1 260/502.4 R 3 Claims, N0 Drawings To prepare liquid concentrates of washing and cleansing agents having a high content of electrolytes on the basis'of non-ionic, surface-active compounds,"
the simultaneous use of so-called hydrotropic sub-" stances or solubilizers is necessary. By-their solu'bilizing capicity it is possible to divide homogeneouslynonionic tensides in salt-containingsolutions and to impart to the cleansing agent concentrates a sufficient stability.
Whereas the sulfonates frequently used for this purpose as hydrotropic substances, as for example toluene sulfonate, xylene sulfonate and cumol sulfonate, generally complywith the requirements in the case'of detergent concentrates on the basis of anion-active detergents, they are ineffective when using non-ionic, surface-active products. However, due to the smaller foaming capacity and the better wetting, emulsifying and cleansing properties, cleansing agents on the basis of non-ionic surface-active compounds are preferred in practice with regard to those basing on anion-active compounds. Therefore, there is a need for hydrotropic solubilizers, which are suitable for such cleansing agent concentrates on the basis of non-ionic tensides.
It is known that solutions containing electrolytes, of
addition of determined phosphoric acid esters, such as for example phosphoric acid monoor diesters of the alkylaryl-polyglycol ethers or of the alkyl-polyglycol ethers. However, the hydrotropic properties of these phosphoric acid esters are only slightly marked, and their effectis not sufficient to dissolve until clear or to disperse the amounts of non-ionic, surface-active com pounds required for the preparation of cleansing agent concentrates, in the presence of high electrolyte concentrations. Thus, for example, in order to maintain in solution about 3 parts of a reaction product of 1 mol of nonyl phenol and mols of ethylene oxide in 100 parts of an aqueous composition corresponding to a usual liquid cleansing concentrate, and containing about 7 of weight of sodium tripolyphosphate, 2 by weight of trisodium phosphate, 3 by weight of sodium metasilicate and I by weight of potassium hydroxide, there are required about 5 by weight of a phosphoric acid monoor diester of an alkylaryl-polyglycol ether or of a fatty alcohol polyglycol ether. Thus, the amounts of these phosphoric acid esters required for the stabilisation of the non-ionic detergent raw materials in solutions having high concentrations of electrolytes, are considerable and lead to a negative influence onto the properties, as for example the foaming capacity and the defoaming capacity, of the cleansing agents.
It has now been found that phosphinic acids or salts thereof of the general formula I wherein R is a straight-chained or branched alkylor alkenyl radical having 4 to 16 carbon atoms, preferably and Y is hydrogen or the sodium or potassium ion, have excellent hydrotropic properties superior to the phosphoric acid esters mentioned, with regard to non-ionic, surface-active compounds, and are therefore, especially suitable for the preparationof liquid aqueous cleansing agent concentrates on th e'basis-of non ionic, surface-active compounds.
The invention further relates to liquid aqueous cleansing agent concentrates on the basis of non-ionic, surface-active compounds,characterized by a content of phosphinic acid derivatives of the general formula I sceletton substances, as they are described for example in the standard work Schwartz, Perry, Berch ;Surface Active Agents and Detergents/volume ll, (l958),
pages 288 to 317. The proportion of, these sceletton substances in the aqueous cleansing agent concentrates is generally up to 35 by weight, especially 5 to 30 by weight. Such sceletton substances are above all alkaliorthoand -polyphosphates, as for example sodium tripolyphosphate or potassium pyrophosphate, in amounts of up to about 20 by weight, preferably 8 to 15 by weight, or organic complexformingagents, as for example ethylene-diamine-tetra-acetate, trisodium citrate or the sodium of the nitrilo-triacetic acid, also in amounts of up to about 20 by weight, especially up to about 12 by weight, and alkali silicates, as for example sodium meta-silicate or sodium-di orftrisilicate, in amounts of up to about 10 by weight, especially up to about 8% by weight.
The aqueous cleansing agent concentrates of the invention may furthermore contain alkali liquors in amounts of up to about 5 by weight, preferably up to 3 by weight, as well as, if required, further usual auxiliaries.
The content of the aqueous cleansing agent concentrates according to the invention of non-ionic detergent raw materials is generally at about 1 to 10 by weight, preferably 2 to 5 by weight, and the content thereof of the phosphinic acid derivatives of the formula I is at about 1 to 5 by weight, preferably L5 to 3.0 %by weight. The content of water of the concentrates is mostly adjusted to about 65 by weight and the pH-value is adjusted to the range of from 8 to 14.
Non-ionic surface-active products, as they may be contained in the liquid cleansing agent concentrates according to the invention, are described for example in the standard work Schwartz, Perry, Berch Surface Active Agents and Detergents, Volume ll, (1958), pages I20 to I38. Preferred non-ionic detergent raw materials are for example:
a. Alkylphenol oxethylates, especially those having 8 to 12 carbon atoms in the alkyl radical and a content of about 4 to 15 oxethylene units,
b. straight-chained or branched, primary or secundary aklylpolyglycol ethers, especially those the alkyl radicals of which comprise about 8 to 20 carbonatoms and which contain .about4 to 20 oxethylene units and, if desired, furthermore a-b out 2 to 20 oxypropylene units in the molecule,.
4 radical R represents methyl. Also preferred are compounds of the formula I, the alkyl radicals of which contain, on the whole, at least 7 carbon atoms.
