Abstract: A mixture is disclosed of at least two alkoxylated alcohols and having the formula (I), in which x is a number between 1 and 12 and y is a number between 1 and 15. One alkoxylated alcohol has as residue R a straight-chain or branched-chain C8-C18-alkyl group and the other alkoxylated alcohol has as residue R a straight-chain or branched-chain C10-C20-alkyl group, but the average number of C atoms in the residues R must differ by at least 0.5, whereas the ratio between both alkoxylated alcohols is comprised between 10 : 90 and 90 : 10. This mixture is suitable as an antifoam tenside additive in cleaning products for machine washing processes.

Abstract: Alkyl glucoside amino carboxylates of the formula in which at least two R substituents are or H, L is an iminodiacetate, aspartate, glutamate, sarcosinate, glycinate, serinate, hydroxyaspartate, ethanolaminoacetate, diethanolamino, alanate or taurinate residue, X is hydrogen, alkali metal, ammonium or substituted ammonium ion, R is R is H or -CH3 and n is 0 to 4, preparation of the compounds of the formula I by esterification of (a) hydroxyalkyl glucosides with (b) maleic anhydride in the molar ratio (a):(b) of 1:at least 2 to 5.5 and addition of amines or amino acids of the formula L-H, in which L has the abovementioned meaning, onto the double bonds of the esters. The compounds of the formula I are used as complexing agents for heavy metal ions.

Abstract: The process entails the extraction of long-chain alkyl glucosides from reaction mixtures which can be obtained by reacting monosaccharides and alcohols containing at least 8 C atoms or by transacetalisation of short-chain alkyl glucosides with alcohols having at least 8 C atoms, and which in each case are adjusted to a pH above 6, with the aid of water.
