The invention relates to amphiphilic compounds of general formula (I), (R , R &mdash;C -C hydrocarbon radical, R &mdash;spacer, X, Y&mdash;functional groups, Z&mdash;1 to 10) with at least two hydrophilic and at least two hydrophobic groups on the basis of amides. The amphiphilic compounds of this invention are highly surface-active and are suitable in particular as emulsifiers, demulsifiers, detergents, dispersants and hydrotropics in industry and household, e.g. in the fields of metalworking, ore extraction, surface treatment, washing and cleaning, cosmetics, medicine and foodstuff processing and preparation.

The invention relates to compounds of formula (I) herein which are reaction products of alkylglycosides with aldehydes and/or diacetals of short-chain alcohols and aldehydes, the acetals obtained being alkoxylated. The invention further relates to a process for producing the above-mentioned compounds and to the use of these compounds for preparing surfactants, especially for industrial detergents and cleaners.

Acid-cleavable surfactants based on alkylglycosides

The preparation of terpolymers by free radical polymerization of an unsaturated dicarboxylic acid with an unsaturated monocarxylic acid and a further saturated monomer which contains no free carboxyl groups, in an aqueous medium, is carried out, according to the invention, in the presence of surfactant compounds.

Process for the preparation of dicarboxylic acid terpolymers for

Use of polyhydroxyalkylamine-N,N-dialkylcarboxylic acids or their salts, as builders for detergents and cleaning agents. Compounds of formula ##STR1## where X represents a polyhydroxyalkyl group with 3 to 7 carbon atoms and which may be glycosidically linked to a mono-, di-, or oligosaccharide; and n is 1 to 3, are used as builders for detergents and cleaning agents.

Use of polyhydroxyalkylamine-N,N-dicarboxylic acids and their salts as

N-polyhydroxyalkyl fatty acid amides are used as thickening agents for liquid aqueous surfactant systems. Compounds of formula ##STR1## where R.sub.1 is an alkyl group; R.sub.2 is hydrogen, an alkyl group, or an alkylene oxide group; and X is a polyhydroxyalkyl group, are used as thickeners. The thickeners are particularly useful in liquid surfactant systems which contain paraffinsulfonate.

Use of n-polyhydroxyalkyl fatty acid amides as thickening agents for

A fabric conditioner comprising 18 to 50% by weight of a mixture of at least two quaternary ammonium salt components (A) and (B) with the remainder of the conditioner being water and auxiliary agents.

Concentrated fabric conditioners

Use of polyhydroxyalkylamine-N,N-dialkylcarboxylic acids or their salts, as builders for detergents and clenaing agents. Compounds of formula ##STR1## where X represents a polyhydroxyalkyl group with 3 to 7 carbon atoms and which may be glycosidically linked to a mono-, di-, or oligosaccharide; and n is 1 to 3, are used as builders for detergents and cleaning agents.

Use of polyhydroxyalkylamine-N-N-dicarboxylic acids and their salts as

A process for the preparation of trialkanolamine di(fatty acid) esters in which a trialkanolamine is reacted with a fatty acid in the presence of small amounts of a fatty acid ester. The trialkanolamine fatty acid diesters obtained can be converted into the quaternary ammonium salt by means of standard quaternizing agents, and the resulting products can be employed as fabric conditioners.
