Abstract: Dental health care compositions including tin pyrophosphate and methods of producing the same are provided. In an exemplary embodiment, a method of producing tin pyrophosphate includes combining tin tetrafluoroborate with a pyrophosphate salt composition to produce a precipitate, where the precipitate includes tin pyrophosphate and a tetrafluoroborate salt. The tetrafluoroborate salt is then removed from the precipitate.

Abstract: The present invention provides methods for utilizing blended compositions of acetonitrile and toluene as organic wash solvents in the production of a synthetic oligonucleotide, the blended compositions producing higher synthetic oligonucleotide yields than a pure acetonitrile wash solvent. The method also provides a process for removing one or more impurities from the acetonitrile and toluene containing wash solvent received as a waste stream from the oligonucleotide synthesis process. The process includes adding at least one of an iodine reactive compound, a sulfur reactive compound and/or an acidic reactive compound to the waste stream, and fractionating the waste stream. The fractionation produces an overhead fraction and a bottom fraction where the overhead fraction includes the acetonitrile and the toluene, and the bottom fraction includes the one or more impurities.

Abstract: The present invention relates to sunscreen compositions containing as UV filters solely a combination of i) bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) and (ii) at least two pigmentary UV-filters. Said compositions exhibit an appealing skin feel and look.

Abstract: A flux paste composition including one or more fluoroaluminate based flux agents, one or more thickening agents, a carrier, a dispersant, a wetting agent, a defoamer, a moderator, and a biocide agent. The flux past composition can be blended with one or more rheological additives selected based upon printing the blended flux composition by a contactless inkjet printing system.

Abstract: The present invention relates to a method for detecting temporally varying thermomechanical stresses and/or stress gradients over the wall thickness of metal bodies, in particular pipelines. In the method, the temperature on the outer surface of the body is measured in order to determine a temperature progression and stress progression therefrom. In addition, electromagnetic ultrasonic transducers are used at at least one measuring point on the outer surface in order to determine the progression of the stresses and/or stress gradients over time over the wall thickness of the body in conjunction with the result of the temperature measurement. The method allows the fatigue monitoring of pipelines even in the event of rapid stress changes.

Abstract: A method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oil component and an aqueous component. The method includes: mixing the invert emulsion drilling fluid with a emulsion clearing agent, wherein the emulsion clearing agent is a mixture of an anionic tensid and a non-ionic tensid; and separating the oil component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaking agent that is a combination of an anionic tensid, a non-ionic tensid and an alkyl polyglycoside tensid.

Abstract: The invention relates to a method for treating metallic surfaces consisting of zinc, magnesium or aluminium or of the alloys of zinc, magnesium or aluminium, to which lacquer, coatings of plastic material, paint, sealants or adhesives are applied after treatment. The treatment of the metallic surfaces takes place at between 10° C. and 100° C. by immersion, spraying or rolling with an aqueous solution. The solution has a pH of between 2 and 13 and contains one or more compounds of the type XYZ at a concentration of between 10−5 and 1 mol/l. Y is an organic group containing between 2 and 50 C atoms and has a straight-chain structure. X is a COOH, HSO3, HSO4, (OH)2PO, (OH)2PO2, (OH)(OR′)PO or (OH)(OR′)PO2 group. Z is a OH, SH, NH2, NHR′, CN, CH═CH2, OCN, epoxy, CH2═CR″—COO, acrylamide, COOH, (OH)2PO, (OH)2PO2, (OH)(OR′)PO or (OH)(OR′)PO2 group. R′ is an alkyl group with between 1 and 4 C atoms.
