Abstract: Non-ionic surfactants are used to reduce the adhesion of microorganisms to surfaces of materials by coating such surfaces with the surfactants or incorporating the surfactants into the materials.

Abstract: The invention relates to silicic acid ester mixtures containing silicic acid esters of formulae (I) and (II), all ‘R’s being selected, independently of each other, from the following group: H, the straight-chained or branched, saturated or unsaturated, substituted or unsubstituted C1–6-hydrocarbon radicals and fragrance alcohol radicals and biocide alcohol radicals, m taking on values of 1 to 20 and n taking on values from 2 to 100.

Abstract: This invention relates to the use of substances that release terpenes and/or perfume alcohols for inhibiting the asexual propagation of fungi. The invention also relates to filter media, building materials, building auxiliaries, textiles, pelts, paper, skins, leather, laundry detergents, cleaning compositions, rinse agents, hand washing preparations, manual dishwashing detergents, and machine dishwashing detergents that contain substances that release terpenes and/or perfume alcohol. The invention further relates to compositions that contain substances that release terpenes and/or perfume alcohols that are used for treating building materials, building auxiliaries, textiles, pelts, paper, skins or leather.

Abstract: A non-therapeutic method for the inhibition of &bgr;-glucuronidase. Body odors result from the decomposition of steroid esters by &bgr;-glucuronidase. Specific &bgr;-glucuronidase-inhibiting compounds are disclosed.

Abstract: The invention relates to silicic acid ester mixtures containing silicic acid esters of formulae (I) and (II), all ‘R's being selected, independently of each other, from the following group: H, the straight-chained or branched, saturated or unsaturated, substituted or unsubstituted C1-6-hydrocarbon radicals and fragrance alcohol radicals and biocide alcohol radicals, m taking on values of 1 to 20 and n taking on values from 2 to 100. These esters of oligosilicic acid with fragrance alcohols or biocide alcohols are characterised by a good hydrolysis stability and can also be used in aqueous media or in processes for producing granulates without undergoing excessive losses of activity.

Abstract: The present invention concerns a new fractionated polydisperse carbohydrate composition having the following definition: an av. DP which is significantly higher than the av. DP of a native polydisperse carbohydrate composition, significantly free of low molecular monomers, dimers, and oligomers, significantly free of impurities chosen among the group consisting of colourings, salts, proteins and organic acids, significantly free of technological aids such as solubility affecting products. The present invention concerns also the preparation process of the composition according to the invention.

Abstract: Process for the highly stereoselective production of trans-3,3 5-trimethylcyclohexyl ethyl ether which comprises contacting 3,3,5-trimethycyclohexenyl ethyl ether with hydrogen in the presence of an effective amount of a palladium catalyst at from about 20.degree. C. to about 100.degree. C.

Abstract: A process for the production of sclareolide comprising the steps of: (1) providing an aqueous composition comprised of: (a) water; (b) sclareol, abienol, or a mixture of sclareol and abienol, (c) an effective amount of a ruthenium catalyst; and, (d) an emulsifying agent; (2) forming an aqueous alkaline composition by adding an alkali metal hydroxide to said aqueous composition; (3) reacting said aqueous alkaline composition with an oxidizing agent to form a crude product; andeither: (4) further reacting said crude product with base to form the salt of 8.alpha.-hydroxy-11-carboxyl-12, 13, 14, 15, 16-pentanorlabdane and; (5) reacting said salt with acid to form sclareolide;or: (4) heating said crude product to form sclareolide.

Abstract: Stereoisomer mixtures of 8,12-oxido-13,14,15,16-tetranorlabdane are obtained in yields of at least 95% by dehydrating cyclization of stereoisomer mixtures of 8,12-dihydroxy-13,14,15,16-tetranorlabdane in the presence of acid-loaded aluminum oxide.

Abstract: A process for the production of sclareolide from sclareol comprising the steps ofA) oxidatively degrading sclareol to a reaction product which is one or both of the following compounds: ##STR1## using either a hypochlorite salt in the presence of a ruthenium salt or potassium permanganate, andB) oxidizing the above reaction product with a peracid or salt thereof to form sclareolide.The above process results in good yields and much shorter reaction times than prior art processes.

Abstract: Certain trimethylbicylo-[4.3.0]-nonane derivatives, particularly those having a single acetyl substituent on the six membered ring, are novel compounds useful as perfumes to give highly persistent iris butter, methyl ionone, tobacco, and wood odor notes.
