摘要:
A 1,3-dialkyl-cyclohexane having the formula: ##STR1## wherein R.sub.1 is a member selected from the group consisting of hydrogen and straight chained or branched C.sub.1 -C.sub.20 -alkyl and R.sub.2 is a straight chained or branched C.sub.1 -C.sub.20 -alkyl; as well as a method of production and its use in cosmetic preparations.
摘要:
This invention is directed to perfume compositions comprising esters of mixtures of tricyclo[5.2.1.0.sup.2.6 ]-decane carboxylic acids of the general formulas: ##STR1## wherein R represents a saturated or unsaturated linear or branched aliphatic hydrocarbon radical having from about 1 to 5 carbon atoms; as well as the use of the compositions as odorants.
摘要:
A perfumery composition consisting essentially of from 1% to 50% by weight of an ester of 3,5,5-trimethylhexanoic acid of the formula ##STR1## wherein R is a member selected from the group consisting of alkyl having from 1 to 5 carbon atoms, alkenyl having from 3 to 5 carbon atoms and alkynyl having from 3 to 5 carbon atoms, and the remainder customary constituents of perfumery compositions; as well as the method of perfuming employing the perfumery composition.
摘要:
2,2,5-Trimethyl-5-phenyl-1,3-dioxane and a perfumery composition consisting essentially of from 1% to 50% by weight of 2,2,5-trimethyl-5-phenyl-1,3-dioxane and the remainder, customary constituents of perfumery compositions.
摘要:
2-Methyl-2-alkyl-alkanoic acid esters of the formula ##STR1## wherein R.sub.1 is a saturated or unsaturated, straight- or branched-chain aliphatic hydrocarbon radical having 1 to 5 carbon atoms, and R.sub.2 and R.sub.3 are independently an alkyl radical having 1 to 4 carbon atoms, which compounds have a wide variety of pleasing and persistent fragrances, and perfume compositions containing them.
摘要:
The invention relates to the use as perfumes of tertiary, alkyl-substituted alcohols corresponding to the general formula ##STR1## in which R.sup.1 and R.sup.2 are individually each a C.sub.1-3 alkyl and R.sup.3 is a C.sub.4-9 alkyl, in compositions containing active chlorine, and to such compositions themselves.
摘要:
Methyl pentanoic acid esters corresponding to the formula ##STR1## wherein R is an olefinically unsaturated, straight-chain or branched-chain or carbocyclic hydrocarbon group, a phenyl or alkyl substituted phenyl group, a phenyl substituted alkyl group, or a phenyl substituted alkenyl group, wherein R contains from 3 to 9 carbon atoms, are valuable perfumes having strong, generally vegetably odor notes and outstanding persistence. They are produced by esterifying 2-methyl pentanoic acid with an unsaturated or carbocyclic alcohol or phenol containing radicals R corresponding to the general formula.The compounds can be effectively combined with other perfumes and standard perfume ingredients to form new compositions. The methyl pentanoic acid ester content thereof generally amounts to between about 1 and about 50% by weight.
摘要:
The invention is directed to a perfumery composition consisting essentially of at least one alkyl-substituted 1,3-dioxolane and customary constituents and to the use of such a perfumery composition to impart a pleasant odor to a product.
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
