Washing agents contain, as additives for inhibiting redeposition and promoting the primary washing action, homopolymers of acrylic acid and of methacrylic acid, copolymers of acrylic acid and methacrylic acid and copolymers which contain, as essential components,

Washing agents containing, as additives, carboxyl-containing copolymers

.beta.-N-aziridinopropionates of relatively high boiling alcohols or polyalcohols are prepared by transesterifying a .beta.-N-aziridinopropionate of a lower alcohol of 1 to 4 carbon atoms with a relatively high boiling alcohol or polyalcohol by a process in which the transesterification is carried out in the presence of, as a transesterification catalyst, a titanium(IV) or tin(IV) compound which is soluble in an organic medium.

Preparation of .beta.-N-aziridinopropionates

The invention relates to ethoxylates of diacetylene dialcohols as well as the use of these compounds as surfactants.

The object of this invention is a moisture-curing, storage stable, single-component polyurethane system comprising:

Moisture-curing, storage stable, single-component polyurethane systems

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

The subject invention relates to compositions of matter having the following structural formula: ##STR1## In this formula, R.sup.1 represents a C.sub.8 -C.sub.20 alkyl radical, R.sup.2 stands for a C.sub.1 -C.sub.5 alkyl radical, and n is a number, 4 through 15. These compounds are low foaming and have acceptable biodegradability. They are particularly useful in the formulation of automatic dishwashing detergents.

Low-foaming, biodegradable alkoxylation products terminated with

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

A process for purifying C.sub.8 -C.sub.16 -alkylglycosides which have been obtained by reacting lower alkylglycosides or hydroxyalkylglycosides with C.sub.8 -C.sub.16 -alcohols in the presence of an acid catalyst, by distillative removal of unconverted C.sub.8 -C.sub.16 -alcohols, wherein the distillative removal, at least of the last amounts of unconverted alcohols, is carried out in the presence of glycols whose boiling points are at most 10.degree. above, and at most 30.degree. below, those of the alcohols to be removed.

Purification of alkylglycosides by distillative removal of unconverted

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.
