Aqueous acidic cleaner formulations

Fatty alcohol oxyalkylates possessing blocked terminal groups are used as low-foam, antifoaming and biodegradable surfactants for industrial cleaning processes, in particular for bottle-washing and metal-cleaning.

Fatty alcohol oxyalkylates, possessing blocked terminal groups, for

Color-stabilized nonionic surfactants which contain chemically bonded polyalkylene oxide groups having terminal hydroxyl groups, and in which are dissolved C.sub.4 -C.sub.8 -aliphatic dicarboxylic acids, their C.sub.1 -C.sub.4 -alkyl esters or mixtures thereof, as color stabilizers.

Color stabilized nonionic surfactants

Compounds of the formula I ##STR1## where R is C.sub.8 -C.sub.20 -alkyl and A is a polyalkylene oxide radical composed of from 4 to 30 alkylene oxide units, of which from 100 to 60 mole % are ethylene oxide units and from 0 to 40 mole % are 1,2-propylene oxide units or 1,2-butylene oxide units or a mixture of these.

Oxyalkylated fatty alcohols having end groups blocked by reaction with

Biodegradable and low-foaming cleaning agents and dishwashing agents containing non-ionic surfactants which have been obtained by reacting one or more adducts of a C.sub.8 -C.sub.20 -alkanol and from 4 to 14 moles of ethylene oxide with 1,2-butylene oxide in a molar ratio of from 1:1.6 to 1:2.4.

Dishwashing agents and cleaning agents containing oxybutylated higher

A detergent and cleanser which contains an oxyalkylated alcohol of the formula ##STR1## where R is C.sub.8 -C.sub.18 -alkyl, x is from 2 to 4.5 and y is from 2 to 5, as a low-foam, biodegradable surfactant additive.

Detergents and cleansers containing oxyalkylated alcohols as

A process for machine dishwashing, employing a rinsing liquor which contains carboxylic acids or hydroxycarboxylic acids or mixtures of these and dihydric, trihydric or tetrahydric alcohols, the alcohols and carboxylic acids being of 5 to 9 carbon atoms, of which one carbon atom is quaternary, the alcoholic hydroxyl groups being exclusively primary and the carboxyl group being bonded to the quaternary carbon atom.

Machine dishwashing, using polyhydric alcohols, carboxylic acids and or

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.

Use of polyhydric alcohols, carboxylic acids, hydroxy-carboxylic acids

To prevent the salting-out of nonionic surfactants from strongly alkaline (pH&gt;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.
