Definitions

• the present invention relates to the use of (oxidized) thioethers of alcohol alkoxylates in detergents and cleaners, especially in dishwashing detergents, and detergents and cleaners, especially dishwashing detergents containing (oxidized) thioethers of alcohol alkoxylates.
• These (oxidized) thioethers are suitable in particular as surfactants with rinse aid function (rinse aid surfactants).
• "Oxidized” refers to the sulfur atom in the thioether which may be in oxidized form as the sulfoxide (SO) or sulfonyl (SO2).
• Surfactants are substances that can lower the interfacial tension.
• surfactants have a characteristic structure and have at least one hydrophilic and at least one hydrophobic functional group. If both parts of the molecule are in equilibrium, the substance will accumulate and align at an interface, i. hydrophilic groups, for example, in an aqueous phase and the hydrophobic groups in the direction of other solid, liquid or gaseous phases.
• Another special feature of surfactants is the formation of higher aggregates, the so-called micelles.
• the surfactant molecules arrange in such a way that the polar groups form, for example, a spherical shell. This causes substances such as dirt particles in an aqueous solution to become soluble to form micelles. Therefore, surfactants are particularly suitable for cleaning surfaces and as an additive in detergents.
• Surfactants having a hydrophobic and a hydrophilic block are widely used. However, their tendency to foaming makes them for many applications not or only partially usable. For applications where strong foaming is not desired, nonionic surfactants have therefore been developed which have a second hydrophobic block, which limits the foam volume.
• the second hydrophobic block can be derived, for example, from a fatty alcohol.
• dishwashing detergents which contain such a surfactant, in particular dishwashing detergents for dishwashers, frequently results in residues remaining on the dishes cleaned therewith (so-called "spotting” in the case of the formation of punctiform linings or "filming") "in the case of film-like coverings).
• the second hydrophobic block may alternatively be derived from a fatty acid.
• dishwashing detergents which contain such surfactants the problem of deposit formation is no longer so great;
• ester group these surfactants are sensitive to hydrolysis, which severely restricts their usability in alkaline formulations and at relatively high temperatures, in particular during prolonged washing operations.
• Thioethers of alcohol alkoxylates and their oxidized form are basically known; e.g. from US 3,627,845.
• This document describes the use of such compounds as biologically active agents, e.g. as fungicides, acaricides and anthelmintics, and as surface active agents in agrochemical formulations and coating agents.
• a use as a detergent or cleaning agent is not mentioned.
• the object of the present invention was to provide compounds which do not have the disadvantages of the surfactants of the prior art.
• the compounds should have no or no strong foaming tendency; they should leave less residue, especially spotting residue, on dishes washed therewith, and they should not or at least be less susceptible to hydrolysis than the fatty acid ester-based surfactants.
• the compounds should have the highest possible melting point, so that they can also be formulated in solid detergents and cleaners.
