A method for passivating metallic surfaces, wherein the surface is contacted with an aqueous composition comprising at least one water-soluble polymer (X) comprising acidic groups and with at least one surfactant (T) based on alkoxylated alcohols, the pH of the composition being in the range from 0.5 to 5, enables durable protection of the surface.

Method for passivating metallic surfaces with aqueous compositions comprising surfactants

The present invention relates to the use of (oxidized) thioethers of polyalkylene oxides in washing and cleaning compositions, especially in dishwashing compositions, and to washing and cleaning compositions, especially dishwashing compositions, which comprise (oxidized) thioethers of alcohol alkoxylates. These (oxidized) thioethers are especially suitable as surfactants with rinse aid function (rinse aid surfactants). 'Oxidized' relates to the sulfur atom in the thioether, which may be present in oxidized form as sulfoxide (SO) or sulfonyl (SO). The invention also relates to particular oxidized thioethers of polyalkylene oxides.

Use of optionally oxidized thioethers of polyalkylene oxides in washing and cleaning compositions

The present invention relates to the use of (oxidized) thioethers of alcohol alkoxylates in washing and cleaning compositions, especially in dishwashing compositions, and to washing and cleaning compositions, especially dishwashing compositions, which comprise (oxidized) thioethers of alcohol alkoxylates. These (oxidized) thioethers are especially suitable as surfactants with rinse aid function (rinse aid surfactants). 'Oxidized' relates to the sulfur atom in the thioether, which may be present in oxidized form as sulfoxide (SO) or sulfonyl (SO).

The present invention relates to low-foam surfactant mixtures of the general formula (I) where R, R, Rand R, l, n and m have the meaning given in the description and the claims, and to the production thereof. For example, R=C-alkyl, R=H, l=5, m=22, n=1, R=methyl and R=C-C-alkyl. The surfactants are suitable for detergent and cleaner formulations.

A process for preparing a C-alcohol mixture comprises The alcohol mixture is suitable for preparing surfactants by alkoxylation, glycosidation, sulfation, phosphation, alkoxylation and subsequent sulfation or alkoxylation and subsequent phosphation.

C13 alcohol mixture and functionalised C13 alcohol mixture

The invention describes a process for the preparation of surfactant alcohols and surfactant alcohol ethers which are, inter alia, highly suitable as surfactants or for the preparation of surfactants. The process, starting from olefin mixtures having a defined minimum content of linear hexenes, gives mixtures having a predominant fraction of branched dodecenes, which are subsequently derivatized to give surfactant alcohols and then optionally alkoxylated. The surfactant alcohol mixture obtained in the process has a degree of branching of from 2.0 to 3.0 and in particular exhibits advantageous properties as regards ecotoxicity and biodegradability. A description is also given of the use of the surfactant alcohols and surfactant alcohol ethers as surfactants by glycosidation or polyglycosidation, sulfation or phosphation.
