Description
of decreasing the rate of evaporation of the vola-' Patented Mar. 19, 1935 PATENT OFFICE PERFUMES, COSMETICS, PERFUMED SOAPS,
ESSENCES, AND ANALOGOUS PREPARA- TIONS John William Hagden, Ilford, England No Drawing. Application May 4, 1932, Serial No. 609,336. In Germany May 30, 1931 2 Claims.
It is known that in the preparation of perfumes, cosmetics, perfumed soaps, essences and the like, the addition ofa suitable high-boiling constituent, known as a fixative, has the effect tile odourous constituents of the preparation, and thus rendering more premanent the odour or taste.
Accordingto this invention, cyclohexyl-cyclo hexanol, or a homologue thereof, is incorporated as a fixative in perfumes, perfumed soaps, essences, cosmetics and the like. Cyclohexyl-cyclohexanol may be prepared by condensing cyclohexanone, in the presence of alkali, to produce cyclohexylidene-cyclohexanone and hydrogenating the latter product with hydrogen in the presence of a catalyst. Methylcyclohexyl-methylcyclohexanoi can be prepared in an analogous way from methylcyclohexanone. l
The fixative action of cyclohexyl-cyclohexanol and its homologues does not depend on the ability of these agents to dissolve the perfume, and is in fact attained with a proportion of the fixative which is insufllcient to dissolve theperfume. In
carrying out the invention, it suflices to use the fixative in about the proportion in which known iixatives are commonly used, say ina quantity amounting to about 5-15 per cent. of that of the perfume to be fixed.
The following examples illustrate the invention and the improvement attained thereby:-
Example 1.To lemon oil is added 5 per cent. of its weight of cyclohexyl-cyclohexanol. The product thus obtained is compared with a similar oil containing a known fixative or not containing a fixative, by soaking filter paper or blotting paper with corresponding quantities of the two solutions. On exposure to air, it is found that the perfume remains perceptible on the paper impregnated with the new mixture long after it has disappeared from that impregnated with the known mixture. Similar results can be obtained in the case of other essential oils, such as bergamot oil or orange oil and in the case of esters, such as arnyl acetate and benzyl acetate. Methylcyclohexyl-methylcyc1ohexanol gives results similar to those obtained with cyclohexylcyclohexanol.
Example 2.A perfume such as eau-de- 10 Cologne is treated with 5-10 per cent. of its weight of one of the fixatives used in accordance with the invention and milled into a toilet soap. After exposure to the air for a month, the soap has a much stronger odour than a sample of the 15 same parent soap containing a known fixative or not containing a fixative and exposed to air for a like period.
Having thus fully described the nature of the said invention and the best means I know for 20 carrying the same into practical effect, I claim:
1. Perfumed preparations for cosmetic and toilet use, including toilet soaps, which preparations contain a substance adapted to impart odour and as a fixative therefor a material selected from the group consisting of cyclohexylcyclohexanol and methylcyclohexyl-methylcyclohexanol. I
2. Perfumed preparations for cosmetic and toilet use, including toilet soaps, which preparations contain a substance adapted to impart odour and as a fixative therefor a material selected from the group consisting of cyclohexylcyclohexanol and methylcyclohexyl-methylcyclohexanol in proportion not exceeding 15 per cent. of the quantity of the substance adapted to impart odour.
JOHN WILLIAM BLAGDEN.
