Processes for the simultaneous production of sterols and polar lipids, in which preparations of vegetable oil lecithin fractions are subjected to ultrafiltration and, on the one hand, the sterols in the permeate and, on the other hand, the polar lipids in the retentate are enriched. The permeate and retentate can subsequently be worked up by methods known per se.

Provided for are rinse aids that exhibit improved drying properties during automatic dish washing and thus allow cleaning methods at lower temperatures than customer reference agents. The rinse aids comprise a) at least one surfactant according to the general formula (I), where R1 is a saturated or unsaturated, branched or linear alkyl or alkenyl radical having 6 to 22 carbon atoms, R2 is hydrogen or an alkyl group having 1 to 6 carbon atoms or a group R3, and R3 is a group A-(O—CH2CHR4—)m—OR5 and R4 and R5 independently from each other are a hydrogen atom or an alkyl group having 1 to 4 carbon atoms and A is a (CH2)n— group or a hydroxyl alkyl group having 2 to 6 carbon atoms and n is an integer from 1 to 6 and m is an integer or a fractional number from 1 to 10 and furthermore b) at least one hydrotrope, c) at least one organic hydroxycarboxylic acid and d) water.

The invention relates to selected surface-active substances of groups a) and b), the surface-active compound a) being selected from compounds of general formula (Ia), wherein M represents a group CH2—CH2 or CHR—CH2, R, R′ or R″ independently represent saturated, unsaturated, linear or branched alkyl groups or alkenyl groups with 6 to 22 C atoms, and the indices n and m independently can have values between 1 and 40, and/or compounds of general formula (Ib), wherein R′″ and R″″ independently represent saturated, unsaturated, linear or branched alkyl groups or alkenyl groups with 4 to 22 C atoms, and the indices n and m independently can have values between 1 and 40 and X′ and X″ independently represent H or saturated, unsaturated, linear or branched alkyl groups or alkenyl groups with 1 to 18 C atoms. The surface active substances of the invention, either on their own or combined with other nonionic surfactants, lead to dishwashing agents with an improved drying performance, especially in multifunctional agents for automatic dishwashers.
