摘要:
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
摘要:
Method of inhibiting discoloration in agents by incorporating iodide salt(s), preferably calcium, potassium and/or sodium iodides into the formulation of those agents. The method is particularly suited for agents comprising vanillin and/or vanillin derivatives, wherein vanillin and/or vanillin derivatives are components of a fragrance mixture and the agents are washing and cleaning agents or cosmetics agents.
摘要:
Silicon compounds comprising at least one silicon atom, at least one alkoxy group of the formula —OR′ bonded to silicon, and at least one aminoalkyl group bonded to silicon, wherein the alkoxy group is derived from an active substance alcohol of the formula R′OH, and the use thereof for perfuming or preserving laundry detergents and cleaners or cosmetic compositions.
摘要:
Mold-resistant construction materials distinguished by the presence therein of an azole alone or in combination with a sporulation inhibitor and/or with a substance which is antiadhesive with respect to microorganisms.
摘要:
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.
摘要:
Scents having a fresh odor are usually very volatile, and therefore have a low yield in typical applications such as washing or cleaning processes. They must therefore be used in relatively large quantities so that commensurate effects can be achieved. The invention describes specific ketones as photolabile scent storage substances which enable greatly improved persistence of the scent impression, in particular with a fresh odor, in typical applications. Corresponding washing or cleaning agents and air freshening agents, and a method for scenting surfaces, are also described.
摘要:
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.
摘要:
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.
摘要:
Silicic acid esters to which fragrances are bound, preferably as 1-aza-3,7-dioxabicyclo[3,3,0]octane compounds or as monocyclic oxazolidines and that are suitable for adding fragrance to detergents and cleaning agents because they release the bound fragrances in hydrolysis.
