Definitions

• a perfume composition uses as an olfactory ingredient in a perfume carrier.
• R is methyl or ethyl and R is branched or nonbranched alkyl having 3-5 carbon atoms.
• the preferred species of ingredient in the carrier is [3,2-dimethyl-5-isopropyl styrene.
• the present invention relates to perfume compositions and novel components thereof that serve as olfactory ingredients.
• the olfactory ingredients of perfume compositions with which the present invention is concerned have the general formula in which R is methyl or ethyl and R is a branched or straight chain alkyl group containing 3-5 carbon atoms, and which may be propyl, isopropyl, butyl, isobutyl, tert.- butyl, pentyl, isopentyl, or the like.
• the preferred group for R is isopropyl.
• the present invention comprises the discovery that the above group of styrene derivatives, especially 6,2-dimethyl S-isopropyl styrene, have high odor value per se and in perfume compositions.
• perfume compositions of course includes not only perfumes which are applied as such, but also the other compositions in which perfumes are incorporated such as cosmetics, soaps, lotions, aerosols, creams, powders, and the like.
• the invention also comprises the discovery of a number of new species of the above genus, which are new per se and which also possess the above desirable perfume characteristics.
• styrene derivatives of the above group exist in stereo-isomeric forms, depending on the orientation of the methyl and the hydrogen that are attached at the fl-position. Both transand cis-isomers but especially the former have the properties of the present invention.
• perfume compositions according to the present invention are as follows.
• Hyacinth composition Parts by weight Isoamyl salicylate 34( Phenylethyl alcohol 25( Cinnamic alcohol 15[ Citronellol 10( Phenylacetaldehyde dimethylacetal 5( Hydratropic aldehyde 3( [3,2-dimethyl S-isopropyl styrene 2f Petitgrain oil L 2f Citronellyl acetate 2i Galbanum oil Petitgrain composition: Parts by weight Menthanyl acetate 250 Linalyl acetate 200 Linalool 200 Geraniol 150 u-Terpineol 65 ,8-Methyl Z-ethyl -isopropyl styrene 50 Geranyl acetate 5O l-limonene 35 EXAMPLE I-II Verveine composition: Parts by weight Oil of lemon grass rect.
• a perfume composition comprising an effective amount of a compound of the formula as an olfactory ingredient in a perfume carrier, in which R is methyl or ethyl and R is branched or nonbranched alkyl having 3-5 carbon atoms.
• a perfume composition comprising as an olfactory ingredient an effective amount of ,8,2-dirnethyl '5-isopropyl styrene in a perfume carrier.
