Detergent mixture of an alkylglycoside surfactant and an hydroxyalkyl

In light colored surfactants produced by sulfonation of fatty acid alkyl esters with less than 2 moles of SO.sub.3 per mole of fatty acid alkyl ester and subsequent work-up of the crude sulfonate in aqueous medium to form salts, the content of .alpha.-sulfofatty acid disalts is regulated and reduced by transesterifying the sulfonation product before its treatment with an aqueous medium with at least about 0.5 mole equivalent of an alcohol, based on the SO.sub.3 which is not for .alpha.-sulfonation.

Control of disalt in .alpha.-sulfofatty acid ester surfactants

The sulfonation of epoxidized ricinoleic acid glycerides with a dry stream of gaseous sulfur trioxide diluted with a carrier gas, followed by a reaction of the sulfonated reaction product with nucleophiles, leads to salt-free and anhydrous products showing surface-active properties.

Use of hydroxyalkyl polyethylene glycol ethers as surfactants in rinse

Aqueous solutions of surface-active hydroxysulfonates are obtained by reaction of unsaturated fatty alkenyl or fatty alkenyl polyalkoxyl esters, for example of oleyl acetate or oleyl polyethoxyl acetate, with sulfur trioxide, introduction of the reaction product into aqueous alkali metal, alkaline-earth or ammonium hydroxide and heating of the solutions until the ester and sultone groups present have been hydrolyzed.

Surface-active hydroxysulfonates

In the production of washing-active .alpha.-sulfofatty acid esters by sulfonation of fatty acid alkyl esters with SO.sub.3 in molar ratios of up to 1:2 and more especially of from 1:1.2 to 1:1.8 and subsequent working-up of the crude sulfonic acid in aqueous medium with salt formation, aqueous pastes which are mobile, more especially pumpable, at moderately elevated temperatures are obtained by subjecting the crude sulfonate before the treatment with the aqueous medium to a post-reaction with at least about 0.5 mole equivalent, based on the SO.sub.3 which is not used for the .alpha.-sulfonation, of monohydric alcohols and/or alkoxylation products thereof at temperatures above 70.degree. C. and adjusting the solids contents of the .alpha.-sulfofatty acid ester salts to more than 35% by weight in the subsequent aqueous working-up step.
