Pharmaceutical preparations containing glycerol alkyl ethers as the solvent.

Pharmaceutical preparations

Novel reagents for the determination of Wassermann antibodies comprising a compound selected from those represented by the formula ##STR1## wherein n is a whole number from 12 to 16 inclusive and

Novel reagent

A process for asymmetrically hydrogenating through the use of microorganisms a double bond connected to tertiary carbon atom in an olefinic aliphatic compound to produce a tertiary, optically active aliphatic compound useful as an intermediate for optically active Vitamins E and K.

Process for the manufacture of tertiary, optically active aliphatic

A process for fermentatively hydrogenating and reducing ketoisophorone to produce optically active [4R,6R]-4-hydroxy-2,6,6-trimethyl-cyclohexanone useful as an intermediate in the production of optically active carotenoids and intermediates in the production of these carotenoids.

Optically active cyclohexane derivatives

Radiation screening preparations comprising a cosmetically acceptable carrier and, as the active ingredient, one or more compounds represented by the formula ##STR1## WHEREIN N IS 1, R.sub.1 is hydrogen, alkyl, alkali metal, ammonium or ammonium substituted with one or more alkyl or hydroxyalkyl residues, R.sub.2 is hydroxymethyl or alkoxymethyl and R.sub.3 is hydrogen; or R.sub.1 and R.sub.2 together constitute a methylene group and R.sub.3 is hydrogen, methyl or ethyl; and wherein n is 2, R.sub.1 is an alkaline earth metal, R.sub.2 is hydroxymethyl or alkoxymethyl and R.sub.3 is hydrogen And pharmaceutically acceptable acid addition salts thereof. The preparations may additionally contain other agents which are characterized by a maximum light absorption in the erythemal range. Certain novel compounds are disclosed.
