A description is given of an optionally fluorinated polyurethane-polymer hybrid dispersion with enhanced surface properties (low critical surface tensions &#x3b3;and very high contact angles &#x3b8;) which is obtainable by The polyurethane-polymer hybrid dispersion of the invention can be prepared in solvent-free or low-solvent fashion and with high solids content and requires only a very low level of stabilizing groups.

Polyurethane-polymer hybrid-dispersion with enhanced surface properties, method for the production and utilization thereof

The present invention relates to a composition and a method for preparing high-concentration aqueous solutions of betaines or amine oxides which comprise a water-soluble carbohydrate. The high-concentration aqueous solutions of the present invention are pumpable, viscous liquids which are self preserving and remain storage stable for long periods without any bacterial decomposition. The high-concentration aqueous solutions of the present invention are prepared by adding a water-soluble carbohydrate such as cyclodextrins or dextrans to an aqueous solution of the betaine or amine oxide and concentrating the aqueous solution to provide the high-concentration aqueous solution.

Particulate bleach activators comprising 15 to 60% by weight of an acetonitrile, 20 to 70% by weight of a silicon-containing carrier material and 20 to 30% by weight of water, which are obtained by applying an aqueous solution, saturated at 10 to 40&deg; C., of an acetonitrile onto the carrier material without subsequent drying, where the amount of saturated aqueous solution is measured such that the given limits for acetonitrile, carrier material and water are observed.

Particulate bleach activators based on acetonitriles

Aqueous, alcoholic or aqueous-alcoholic solutions of a monoalkylamine and a reducing sugar are simultaneously injected into a mixing unit and the two solutions are mixed under turbulence in the mixing unit for 6 seconds to 5 minutes at a temperature of 25 to 60&deg; C. and a pressure of 50 to 90 bar. The mixture is then added to a hydrogenation reactor and hydrogenated with hydrogen in the presence of a hydrogenation catalyst. An alkylpolyhydroxyalkylamine is obtained in high yield and with high purity.

Laundry softener concentrates

The invention relates to mixtures comprising acetals and oleophilic alcohols and/or oleophilic esters which are suitable for the preparation of inverted emulsion drilling muds and emulsion drilling muds. They completely or partly replace here the base oils, diesel oil, purified diesel oil, white oil, olefins and alkylbenzenes known to date. The invention furthermore relates to the use of the inverted emulsion drilling mud and emulsion drilling mud as claimed in claim 10.

Use of acetal-containing mixtures

Acetals are used as a mineral oil substitute, oil component or base oil in invert-emulsion drilling muds, emulsion drilling muds, engine oils, gearbox oils, lubricating oils and also metal-working fluids, coolants, cooling lubricants and hydraulic fluids. As compared with conventional mineral oils, acetals show good biodegradability and are less toxic.
