20110251407PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE ORGANIC CARBOXYLIC ACID - The present invention is a simple method, in which a specific amount of alkali is added to an enantiomeric mixture of an optically active organic carboxylic acid where enantiomers are present in a non-equimolar ratio, or in which the enantiomeric mixture of an optically active organic carboxylic acid is neutralized with an alkali, and then a specific amount of acid is added thereto, thereby separating an organic carboxylic acid salt in the mother liquor and a crystallized organic carboxylic acid from each other. The method makes it possible to obtain an optically active organic carboxylic acid with improved enantiomeric excess. The present invention provides a simple production method for obtaining an optically active organic carboxylic acid with improved enantiomeric excess from an enantiomeric mixture of an optically active organic carboxylic acid where enantiomers are present in a non-equimolar ratio.10-13-2011

20100010241Cosmetics - The present invention provides a cosmetic having equal to or a higher antioxidant activity and moisture retaining property than the above-described conventional vitamin E derivatives. The cosmetic also has an excellent emulsifying ability and solubilizing ability and remarkably reduces a sticky feeling on the skin (in particular, the sticky feeling during drying after the application on the skin). That is, the cosmetic of the present invention containing a vitamin E derivative represented by the following formula (I) or a salt thereof.01-14-2010

20140155636PROCESS OF SEPARATING CHIRAL ISOMERS OF CHROMAN COMPOUNDS AND THEIR DERIVATIVES AND PRECURSORS - The present invention relates to a process of separating chiral isomers of chroman compounds, particularly tocopherols and tocotrienols as well as the esters and intermediates thereof. It has been found that this process allows a separation of the desired isomer with a higher yield and enables the use of the non-desired isomers in a very efficient way. Said process is particularly useful when implemented in an industrial process. Furthermore, it has been found that this process allows using isomer mixtures as they result from traditional industrial synthesis.06-05-2014
