    Abstract: The claimed polyhydroxy amide sulphosuccinates have formula (1), where R is an alkyl group, R CO is an acyl group, y is a number between 3 and 9 and Z(OX)y is a polyhydroxy hydrocarbon group partially esterified with maleic acid or maleic acid anhydride and subsequently sulphited, and X is hydrogen or a sulphosuccinate group. The claimed sulphosuccinates and in particular mixtures thereof with fatty alcohol alkoxylate-sulphosuccinates have among other things very good foaming qualities, very good skin compatability and an unexpectedly high capacity for thickening in combination with standard ether sulphates and alkali metal salts such as sodium chloride.

    Abstract: Stable and homogeneous aqueous formulations of surfactants with an HLB of less than or equal to 13, which additionally contain a compound of the formula I in which R is C1-C8-alkyl, C1-C8-alkenyl, phenyl, alkylphenyl or phenalkyl with, in each case, 1 to 4 C atoms in the alkyl chain or cyclohexyl, R is hydrogen, or one of the radicals mentioned for R or R and R together with the N atom denote a heterocyclic radical, M is an alkali metal or ammonium cation or an equivalent of an alkaline earth or aluminium cation, and m and n are each, independently of one another, numbers from 6 to 8. The presence of the compounds of the formula I makes it possible to prepare stable and homogeneous aqueous formulations even of those surfactants which are otherwise only sparingly soluble or even insoluble in water.

    Abstract: In the novel process for the purification of an alkylene oxide adduct which has been prepared using halogen-containing metal catalysts and contains halogen-containing compounds and metals as impurities, the alkylene oxide adduct to be purified is treated with an excess of the alkali metal compound, and the alkaline mixture obtained is brought to a pH of not more than 7 using an acid, with the proviso that the amount of water present in the resulting product mixture is at least 0.1% by weight, relative to the weight of the product. This product mixture is freed from water and other solvents, as a result of which the salts insoluble in the alkylene oxide adduct precipitate in the form of coarse crystals and can be easily separated off to give the desired pure alkylene oxide adduct.
