Use of detergent mixtures for the production of toilet blocks

Fatty alcohol (ether) sulfates which are obtained by co-sulfating mixtures of (a) C.sub.8-22 fatty alcohols and (b) C.sub.8-22 fatty alcohol ethoxylates containing an average of 1.9 to 3.9 ethylene oxide units in a ratio by weight of 20:80 to 80:20, and then neutralizing the mixtures thus co-sulfated with aqueous bases. The substances have distinctly improved low-temperature behavior in relation to ether sulfates with comparable degrees of ethoxylation, and are useful as components of surface-active compositions.

Process for the production of light-colored .alpha.-sulfofatty acid

A process for the production of solid or paste-form products by fast reactions is carried out stoichiometrically wherein a gaseous medium is introduced into each of the reactants to be reacted with one another, the reactant streams formed are combined and are subsequently forced through a spray unit in a weight ratio of gaseous medium to product stream of from 0.04 to 0.3 (kg/kg) and at a rate of 0.1 to 15 m/second, as calculated from the gas-free reactant streams and based on the free cross-section of the spray unit. The products obtained are free from readily volatile constituents.

Process for the production of solid or paste-form products

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.
