Abstract: Novel aqueous coolants with improved temperature stability contain (A) water; (B) at least one alkylene glycol, alkylene glycol monoalkyl ether, or glycerol; (C) at least one phosphate, carbonate, and/or sulfate in the form of its free acids or its salts; (D) at least one hard water stabilizer; and optionally, further inhibitors and typical coolant constituents. The aqueous coolants are useful, for example, in internal combustion engines.

Abstract: A method for manufacturing a multi-layered confectionery shell is provided. The method includes depositing a first edible liquid into a mould cavity, depositing at least one other edible liquid onto the first edible liquid in the mould cavity, and pressing the edible liquids in the mould cavity using a stamp having a surface temperature below the solidification temperature of each of the edible liquids to form at least two shell layers. The ratio of the apparent viscosity of each edible liquid having one or more other edible liquids deposited directly thereon to the apparent viscosity of said other edible liquid(s) is 0.8 or less or 1.5 or more, the viscosities of the liquids being measured at a shear rate of 5 s?1 and at a liquid temperature of 40° C. A multi-layered confectionery shell obtainable by this method is also provided.

Abstract: The invention provides pulverulent, emulsifier-free, hydrophobic, polyurethane-based thickener preparations which lend themselves particularly well to incorporation into water-based inks, paints, and varnishes, and to their use as rheological additives for thickening preferably aqueous systems, comprising a) at least one water-soluble active polyurethane thickener substance; and b) at least one water-insoluble or sparingly water-soluble active polyurethane thickener substance.

Abstract: The invention provides for thickeners for inks and coating materials, comprising polyurethanes, water, viscosity regulators, and, if desired, organic solvents, wherein said viscosity regulators comprise compounds of the general formula (I) R1—O—(SO)a—(EO)b—(PO)c—(BO)d-(DTO)e—R2 in which R1 and R2 independently of one another are one of the radicals from the group consisting of hydrogen, an aliphatic or cycloaliphatic hydrocarbon radical which optionally is substituted and/or contains multiple bonds and/or contains heteroatoms, an aromatic radical which optionally is substituted and/or contains heteroatoms, an acyl radical, a carboxyacyl radical, and a carboxyalkyl radical, a=1 to 5, b=3 to 30, c=0 to 5, d=0 to 5, and e=0 to 5 where (a+c+d+e)<=b.

Abstract: Branched polyurethanes which are preparable by reacting A) one or more aliphatic and/or aromatic isocyanates having a functionality of at least three with B) from 90.0 to 99.8 eq. % of one or more polyethers of the structure RO(SO)w(BO)x(PO)y(EO)zH ?and C) from 0.2 to 10.0 eq. % of at least one of the compounds from the following group: a. polyethers b. polyether polydimethylsiloxane diols c. polyester polydimethylsiloxane diols d. polydimethylsiloxane diols e. polydimethylsiloxane diamines f. polyether diamines.
