Abstract: By fluidized-bed spray granulation, dextrin granules having a high content of enclosed alcohol are obtained from dextrin/water/alcohol mixtures.

Abstract: The invention relates to N-substituted benzazoles, processes for their preparation and their use as UV absorbers.

Abstract: The invention relates to a composition which donates an odoriferous substance and absorbs moisture, and can preferably be employed in wardrobes and similar containers, and in small rooms, for keeping the atmosphere dry.

Abstract: Ethylvanillin isobutyrate is a valuable new fragrance and flavor substance which, because of its extraordinary organoleptic profile and its favorable technical properties, permits hitherto unknown effects in perfumery and flavoring.

Abstract: Use of 3-acylthiohexyl esters of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently of one another represent hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.5 -C.sub.12 -aryl, including furyl and thienyl, as aroma and/or odoriferous substances, and aroma and odoriferous substance compositions containing these compounds.

Abstract: Lactic acid menthyl ester can be stabilized by addition of alkali metal carbonate and/or bicarbonate and/or alkaline earth metal carbonate and/or bicarbonate.

Abstract: Open-chain branched olefinically unsaturated alcohols and esters are excellent aroma substances.

Abstract: Trans-2,cis-4-decadienoic acid ethyl ester can be prepared from Stillingia oil by enzymatic transesterification with lipase from Candida antarctica in the presence of ethanol.

Abstract: Asymmetric carbonates, thiocarbonates and urethanes having a physiological cooling effect on the skin and on mucosae are described.

Abstract: In the photooxidation of terpene olefins, fewer by-products and higher conversion rates are obtained if a very high irradiation intensity is chosen.

Abstract: Compounds which, per molecule, contain at least 2 benzazolyl groups are outstandingly suitable as UV absorbers for sunscreen compositions.

Abstract: The invention relates to finely divided, highly pure neutral zinc oxide powder used for UV protection in cosmetic sun screen preparations and daytime skin care preparations as well as in lacquers and plastics, and to a process for its preparation.

Abstract: Ferulic acid, vanillic acid, coniferyl alcohol and coniferyl aldehyde can be prepared from eugenol with the aid of a new Pseudomonas species.

Abstract: Disclosed is a process for the preparation of aliphatic carboxylic acids by microbial oxidation of alcohols with relatively long, optionally branched C chains by means of atmospheric oxygen, in which the bacteria species Gluconobacter roseus is used as the microorganism. Contemplated is the use of Gluconobacter roseus strain IAM 1841 to oxidize n-butanol, isobutanol, 2-methylbutanol and 3-methylbutanol to the corresponding acids. Also contemplated is the use of Gluconobacter roseus strain IFO 3990 to oxidize isobutanol, 2-methylbutanol and 3-methylbutanol to the corresponding acids.

Abstract: Thioalkane .alpha.,.beta.-diketones have interesting organoleptic properties and are therefore suitable as aroma substances.

Abstract: In the preparation of substituted 2-cyanocinnamic esters by the Knoevenagel condensation of cyanoacetic esters and carbonyl compounds, the reaction times for obtaining high yields can be considerably reduced by using C.sub.3 -C.sub.6 -monocarboxylic acids and ammonium compounds as catalysts.

Abstract: Ferulic acid, vanillic acid, coniferyl alcohol and coniferyl aldehyde can be prepared from eugenol with the aid of a new Pseudomonas species.

Abstract: Coniferyl aldehyde can be prepared from eugenol with the aid of fungi or their constituents.

Abstract: The invention relates to new derivatives of macrocyclic lactones, a process for their preparation, a pyrolysis process using these new derivatives and the use of the pyrolysis products for the preparation of saturated macrocyclic lactones.

Abstract: Ketals, preferably glycerol ketals such as, for example, 1-menthone glycerol ketal or 3,3,5-trimethylcyclohexanone glycerol ketal, have a physiological cooling effect and are therefore suitable as active compounds in compositions which are intended to cause a sensation of freshness on human skin or mucous membrane.
