摘要:
A Compound corresponding to formula (I): wherein X is a group selected from the group consisting of —CHO, —CN, —CH═NOH, and —CH2OH, and wherein the C═C double bond assumes a Z or E configuration.
摘要:
Compounds of the general formula (I) are described: wherein each of R1, R2, R3, R4, R5 and R6 independently represents a substituent selected from the group consisting of hydrogen, methyl, ethyl, n-propyl, and isopropyl; an wherein x represents either 0 or 1. The compounds are useful as fragrances and as added components in fragrance blends. Methods of improving the harmony, emanation, naturalness an staying power of other fragrance ingredients by the addition of such compounds are also described.
摘要:
Compounds of the formula (I): wherein X is a —(C═CH2)— group or a —CH(CH3)— group, with the proviso that when X is a —(C═CH2)— group, R1 is a C1-10 alkyl group or a C2-10 alkenyl group and when X is a —CH(CH3)— group, R1 is hydrogen, a saturated or unsaturated, linear or a branched C1-10 alkyl group, a C1-10 acyl group, a C1-10 cycloalkyl group or an aryl group are useful as perfumes.
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:
Due to toxicological concerns, it may be desirable to replace the fragrance compound lilial with less problematic compounds without losing the creative power and quality regarding perfumes. The present invention addresses this need by using selected oxazolidines described herein.
摘要:
An electrical surface acoustic wave filter with a wafershaped substrate (1) of monocrystalline, piezoelectric material, in particular lithium niobate, wherein one substrate side supports interdigital transducers (IW 1, IW 2) with metallic electrodes mutually engaging in comblike fashion for the stimulation and coupling out of the surface waves and with plastic and/or elastic damping compounds (10, 11) for the suppression of disturbing wave reflections. The damping compound (10, 11) is applied indirectly or directly to the substrate surface between the active interdigital transducer area "b" and the adjacent long substrate edges (4, 5) of at least one interdigital transducer (IW 1), and that at least in the inactive interdigital transducer areas (a, a).
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:
A detergent, cleaning, conditioning or cosmetic agent that is absorbed by the surface of substrates and that contains oligomers, polymers or copolymers comprising a specific structural element. The agent may also form part of a conditioning substrate, wherein the substrate, such as a fleece material, is saturated and/or coated with the agent. The agent may also be used in a process for treating hard and/or soft substrate surfaces comprising the step of applying an effective quantity of the agent to the substrate.
