摘要:
Carbonyl compounds derived from the reaction of alkyl cyclopentenols and vinyl ethers are described. The carbonyl compounds described have excellent fragrance properties, and their use as fragrances and/or fragrance-enhancing compounds is also described. Processes for the preparation of the carbonyl compounds are described as well.
摘要:
The use of aldehydes as odorous materials, which can be produced through partial or total hydroformylation of cyclooctadienes, except cyclooctane aldehydes, is described. The fragrance enhancing capacity of the compounds is described in methods for their use both as perfumes and perfume enhancers or boosters.
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 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:
Compounds of the formula (I): wherein the bond between the α- and β-positions to the aldehyde group represents a C—C single bond or a cis- or trans-configured C═C double bond are useful as perfumes and perfume ingredients.
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:
Odoriferous compounds containing from 70 to 90% by weight of 2-methylene-3-(4-methlycyclohex-3-enyl)-butanal and from 10 to 30% by weight of limonene aldehyde, are described. The fragrance providing capabilities of the compounds are described in methods for their use, and perfumed compositions containing such compounds are also described.
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.
