Abstract: Strongly alkaline, aq. solns. of nonionic surfactants are prepd. by adding, as solubilisers, ene-adducts, (I), of maleic anhydride to unsaturated 12-24C fatty acids or their triglycerides. Wt. ratio solubiliser:surfactant is 1:1 to 10:1. (I) prevent formation of a separate phase, e.g. at pH 9-12 and have a wide activity range. Solubilising activity is based on the simultaneous presence of hydrophilic carboxylate gps. and lipophilic mol. residue.

Abstract: Monoalkyl orthophosphate(s) (I) contg. =50 wt.% di-/trialkyl orthophosphates (wherein the alkyl moieties contain 8-30C) are used as foam inhibiters in cationic detergent formulations. The detergent formulations are used in dishwashing machines. Besides being unexpectedly compatible with cationic surfactants (I) have a disinfecting action.

Abstract: A method for regulating the viscosity of aqueous detergent and cleanser slurries, in which there are added to the slurries, as viscosity regulators, dihydric, trihydric or tetrahydric aliphatic alcohols, monobasic aliphatic carboxylic acids, hydroxycarboxylic acids, esters of the said alcohols and the said acids or mixtures of these, in which compounds the alcohols, carboxylic acids and hydroxycarboxylic acids, and the individual components of the esters, are of 5 to 9 carbon atoms, of which one is a quaternary atom, the alcohols and hydroxycarboxylic acids carry exclusively primary alcohol groups, and the carboxylic acids and hydroxycarboxylic acids have the carboxyl group bonded to the quaternary carbon atom.

Abstract: To prevent the salting-out of nonionic surfactants from strongly alkaline (pH>9) aqueous solutions, solubilizers have been proposed but existing solubilizers do not have a sufficiently broad action spectrum. The invention seeks to provide solubilizers having a broader action spectrum and provides for this purpose monocarboxylic acids of 6 to 11 carbon atoms optionally in admixture with ene-adducts of maleic anhydride and unsaturated fatty acids of 12 to 24 carbon atoms or their triglycerides. The solutions are useful as cleansers and in the textile industry.

Abstract: Disch washing detergents suitable for dish washing machines contain a cpd. of formula (I) R1(C2H4O)n(C3H6O)mH (I) (where R1 is of formula (II) or (III) R2-CONHCH2CH2-NH-CH2CH2-A- (II) (where A is -O- or -NH- and R2 is a 10-22C (un)satd. alkyl residue; n is 0-6; m is 0-6; (m+n) 1). (I) produces antifoaming action at both high and low temps. and has excellent cleaning properties.

Abstract: A phosphate-free dishwashing composition contains at least one partially neutralised amino polycarboxylic acid, alkali metal salts of (co)polymers which are free of nitrogen and contain carboxyl groups, alkoxylated H-active compounds whose cloud point is below the temperature of the washing liquor, and, where appropriate (di)alkylbenzenesulphonates and glycols or glycol ethers, where the aqueous solutions of the composition have a pH of from 6 to 8.5. The dishwashing compositions can be employed as aqueous 10 to 70% by weight concentrates.
