The invention relates to the use of ortho-phenylphenol and/or derivatives thereof for inhibiting the asexual reproduction of fungi, to ortho-phenylphenol and/or filter materials, building materials, auxiliary building materials, textiles, pelts, paper, felt or leather, all of which containing derivatives of ortho-phenylphenol, as well as to detergents, cleansers, rinsing agents, hand detergents, hand dishwashing detergents, dishwasher detergents, and agents for finishing building materials, auxiliary building materials, textiles, furs, paper, hides or leather.
摘要:
Un procédé permet de produire du trans-3,5,5-triméthylcyclohexyl-éthyléther avec adjonction de quantités minimes de cis-éther. A cet effet, on hydrogène du 3,3,5-triméthylcyclohexenyl-éthyléther en présence de catalyseurs au palladium à des températures comprises entre 20 et 100 °C et sous une pression d'hydrogène comprise entre 1 et 10 bars, sans utiliser de solvants, et on traite le produit d'hydrogénation de la manière usuelle.
摘要:
The use of mistletoe extracts provides a promising potential for the tyrosinase-inhibiting cosmetic brightening of skin. Especially in Asiatic countries where a brightening of the skin is desired, mistletoe extract based cosmetics represent a gentle and valuable alternative vis-à-vis conventional depigmentation agents.
摘要:
The invention relates to urethane compounds which release organoleptically active aromatic alcohols; a method for producing said urethane compounds; and the use thereof in cosmetic, glue, paint and plastic compositions, and cleaning product, softener, washing-up and dishwasher detergent compositions.
摘要:
Sclareolide, an important preliminary product for the production of the perfume ambroxane, is accessible in large quantities with short reaction times by the reaction of sclareol and/or abienol in an aqueous medium and in the absence of an organic solvent with a 10.5 to 25-fold molar quantity of an oxidising agent in the presence of a ruthenium catalyst and an emulsifier to form a raw product and either (i) its conversion in the presence of a base into the salt of 8α-hydroxy-11-carboxy-12,13,14,15,16-pentanorlabdane and its further cycling in an acid medium, or (ii) is subsequent reaction at increased temperature and subsequent distillation, whereby the post-reaction may also, if desired, take place in situ during distillation.
摘要:
The invention concerns the cyclization, by the removal of water, of mixtures of stereoisomers of 8,12-dihydroxy-13,14,15,16-tetranorlabdane in the presence of acidified aluminium oxide. The cyclization reaction gives yields of at least 95 % of mixtures of stereoisomers of 8,12-oxido-13,14,15,16-tetranorlabdane.
摘要:
On obtient des mélanges de stéréoisomères de 8,12-oxido-13,14,15,16-tétranorlabdane, avec un rendement d'au moins 95 %, par cyclisation déshydratante de mélanges de stéréoisomères de 8,12-dihydroxy-13,14,15,16-tétranorlabdane en présence d'oxyde d'aluminium acidifié.
摘要:
The invention relates to the use or eugenol and/or the derivatives thereof for inhibiting the asexual reproduction of fungi. The invention also relates to filter media, building materials, auxiliary building materials, textiles, furs, paper, skins or leather containing eugenol or the derivatives thereof, but also washing agents, cleaning agents, rinsing agents, handwashing agents, agents for handwashing dishes, dishwasher agents, and agents for finishing building materials, auxiliary building materials, textiles, furs, paper, skins or leather.
摘要:
The invention relates to aqueous, gel-like compositions of odoriferous substances, comprising a gel matrix and a derivative of an odoriferous substance, said derivative releasing the odour under the influence of protons. The invention also relates to a method for producing said gel-like compositions of odoriferous substances and the use thereof as additives in cleaning products, cosmetic products, deodorants, paints and varnishes.
