Evonik Industries is an industrial corporation headquartered in Essen, North Rhine-Westphalia, Germany, one of the world's leading specialty chemicals companies, owned by RAG Foundation. It was created on 12 September 2007 as a result of restructuring of the mining and technology group RAG. Evonik Industries united the business areas of chemicals, energy and real estate of RAG, while mining operations continue to be carried out by RAG. Since then, the energy and real estate business areas have been divested, with a minority share in the former and a majority share in the latter still being held. Its chemicals business already generates more than 80% of sales in areas in which it ranks among the market leaders. Evonik Industries employs about 34,000 people and carries out activities in more than 100 countries. The operating activities are organized into six business units which are a part of the chemicals business area. Evonik is the main sponsor of German football club Borussia Dortmund. Wikipedia.

Patent
Evonik Industries | Date: 2017-03-29

The present invention relates to a cell for producing acyl glycinateswherein the cell is genetically modified to comprise -at least a first genetic mutation that increases the expression relative to the wild type cell of an amino acid-N-acyl-transferase, -at least a second genetic mutation that increases the expression relative to the wild type cell of an acyl-CoA synthetase, and -at least a third genetic mutation that decreases the expression relative to the wild type cell of at least one enzyme selected from the group consisting of an enzyme of the glycine cleavage system, glycine hydroxymethyltransferase (GlyA) and threoninealdolase (LtaE).


The invention relates to hair care formulations containing silanes which respectively comprise at least two alkoxy groups and a guanidino or carbamide group, and to different uses of the above-mentioned silanes for hair care and for hair protection.


The invention relates to a method for producing trimeric and/or quaternary silicon compounds or trimeric and/or quaternary germanium compounds. A mixture of silicon compounds or a mixture of germanium compounds is exposed to a non-thermal plasma and the resulting phase is subjected, at least once to vacuum rectification and filtration.


The present invention relates to a method for producing aqueous hydrolysates from aminoalkyltrialkoxysilanes by (a) introducing water, optionally warming, (c) adding hydrolysable silanes consisting of at least one aminoalkyltrialkoxysilane in an amount which provides a molar ratio of water to the total amount of aminoalklytrialkoxysilane of 10.5 to 20, (c) distilling off of the alkylalcohol during the reaction, wherein the solids content in a so produced aqueous compound is 30 to 55 wt.% in relation to the compound and the aqueous solution has a total content of free and bonded alkylalcohol of less than or equal to 1 wt.% in relation to the compound.

The present invention relates to a process for producing cycloalkenamer-containing compositions, comprising the steps of: a) converting at least one cycloalkene by ring-opening metathetic polymerization to obtain a polyalkenamer-containing product mixture, and b) working up the product mixture to remove monomers and oligomers of the cycloalkenes to obtain the polyalkenamer-containing composition by extraction with CO2, wherein the extraction comprises at least two stages: b1) an extraction with liquid CO2 under the supercritical conditions and then b2) an extraction with supercritical CO2. The invention further relates to the use of these cycloalkenamer-containing compositions in the field of packaging materials, especially for food and drink.

The present invention relates to a gastric retention active delivery system in the form of a coated capsule, which, in contrast to prior art delivery systems exhibiting relatively poor floating-properties, and thus requiring size expansion capability in order to securely delay passage through the pylorus, reliably stay afloat for several hours. This is achieved by combining pore forming components and flexible polymer components in the coating in suitable proportions. The present invention, further, relates to the use of gastric retention active delivery systems of the invention for the delivery of one or more water soluble active components A to a mammal.


The present invention provides a cationic arabinoxylan and the hydrophobically modified product thereof. The cationic arabinoxylan is prepared based on a cereal arabinoxylan and a quaternizing agent, with water as solvent and strong alkali as catalyst. The hydrophobically modified product is prepared based on cationic arabinoxylan and alkyl halide, with pyridine as catalyst. Said cationic arabinoxylan and the hydrophobically modified product thereof can be used as a conditioning agent or thickener in cosmetics or personal care compositions, and can also be used in textile, papermaking, pharmaceutical and food industry applications.

The current invention relates to a microvesicle based method of detecting avian necrotic enteritis as well as to new markers which have been identified as suitable for detection of avian necrotic enteritis and/or avian infection by Clostridium perfringens:


The present invention relates to compounds according to formula (I) and to heat-curable resin compositions based on polymaleimide resin systems comprising such compounds as comonomers:^(1) is hydrogen or an alkenylphenoxy group,R^(2) is an alkenylphenoxy group, andR^(3) is hydrogen or an alkyl group with 1 to 4 carbon atoms. The present invention also relates to crosslinked resins obtainable by curing such compositions. Compounds of the present invention can be used amongst others in fields like structural adhesives, matrix resins for fiber prepregs, moulding compounds, as well as structural and/or electrical composites.
