Abstract: A process for the preparation of a saturated butanone having a terminal substituted aryl group (I) by the selective reduction of an aryl-substituted .alpha.,.beta.-unsaturated butanone (II) is presented. The aryl moiety can be mono- or polysubstituted by one or more C.sub.1 -C.sub.6 alkoxy, methylenedioxy or hydroxyl radicals and R is a C.sub.1 -C.sub.6 radical. The .alpha.,.beta.-unsaturated butanone (II) is subjected to the action of the enzymes of a yeast or of a filamentous fungus to give a mixture of (I) and an alcohol (III). (I) and (III) are isolated and purified. (III) can be enzymatically oxidized to provide (I).

Abstract: Deodorant compositions containing at least two aldehydes include at least one aldehyde selected from acyclic aliphatic aldehydes, non-terpenic aliphatic aldehydes, non-terpenic alicyclic aldehydes, terpenic aldehydes, aliphatic aldehydes substituted by an aromatic group and bifunctional aldehydes; and one aldehyde selected from aldehydes possessing a non-aromatic unsaturation carried by the carbon which is alpha to the aldehyde, aldehydes possessing an unsaturation alpha to the aldehyde function conjugated with an aromatic ring, and the aldehydes in which the aldehyde group is on an aromatic ring.

Abstract: Use of derivatives of 6,6-dimethyl-2-acylcyclohex-4-en-1,3-diones in the sun protection sector of the cosmetics industry and preparations containing these derivatives, novel derivative and process for the production thereof.Use of a 6,6-dimethyl-2-acylcyclohex-4-en-1,3-dione derivative of the formula (I) ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.6 alkyl radical, R.sub.2 is a hydrogen atom or a C.sub.1 -C.sub.6 alkyl radical, R.sub.3 is a hydrogen atom, a hydroxy radical or a C.sub.1 -C.sub.6 alkoxy radical as a sunscreen, preparations containing this derivative, novel derivative and process for the production thereof.
