PERFUME.
969,636. Specification of Letters Patent. No Drawing.-
To all whom it may concern:
Be it known that I, CLnarnNs Osman K'Lnisnn, a citizen of Germany, residing at the village of Clifton, in the county of Passaic and Stateof New Jersey, have invented certain new and useful Improvements in Perfumes; and I do hereby declare the followingto be a full, clear, and exact descrip tion 'of the invention, such as will enable others skilled in the artto which .it appertains to make and use the same.
This invention has for its objectthe provision of improved perfume bases and also has for its object the manufacture of new and improved perfumes by the use of such new and improved bases.
In the manufacture of perfume'ry, the base or solvent for theodoriferous and other substances used should have the following properties :It should be, colorless, odorless, have a very low :t reezing point, be nonpoisonous, non-irritant to the skin and only slowly Volatile but must have good solvent properties. At present, as the base or solvent in the n1a ority of perfumes manufactured, alcohol is used.
It is apparent that not many substances respond to all of the above tests but I believe I have discovered a series of compounds which are suitable for this inafter described.
I have found by experiment that the esters of orthophthalic acid of the general formula coon, \cooa,
purpose as here- 1n which R, and R represent any alkyl radical such as methyl, ethyl, propyl, butyl,
.amyl, etc, or their isomers fulfil the above tests. It is of course, understood, that in stead of esters of ortho-phthalie' acid of the in which the same alkyl radical is resent in both 'carboxyl' groups are equa lysatisfznctory. In practice I have. found that as Application filed February 1, 1910, Serial ll'o. 541,3 85.
examples of such solvents or bases which are satisfactory, ell-ethyl esters of orth0- phthalic acid oooo n,
\COOC,H methyl-ethyl esters of ortho-phthalic acid C()OCH 6 \oooo,u, and dianethyl esters of ortho-phthalic acid /C()OCH \oooon,
but it will be apparent from the constitution of phthalic acid that a large number of esters of phthalic acid may beemployed for this purpose. The esters of isophthalic and terephthalic acids of-the formulae and G' HACOOHMfl-A) may also be used for this purpose but are at resent of no practical importance.
The neutral esters of ortho-phthalic acid such as I employ are colorless,practically odorless,-have a low freezing point, are not readily inflammable, do not irritate the skin and are non-poisonous. They are miscible with alcohol, ether, chloroform and glycerin in all proportions. They are excellent solvents of the various essential oils, balsains, synthetic compounds such as artificial musk, cumarin and other substances used in the manufacture of perfumery an l while themselves possessing the properties of blending the various odoriferous mate- 'rialsin a satisfactory manner are comparatively stable and Without chemical action on the substances dissolved. On account of their-high boiling points ranging between 275 and 325 degrees, they volatilize very slowly but finally completely without leaving any stain on fabrics.
As an example of a. perfume made with esters of orth'o hthalic acid, I take 95 parts of the di-n1ethy ester of ortho-phthalic acld and dissolve in same one part each of the following substances, oil of bergamot, oil of geranium, ionone, linalol and-tincture of musk, the whole comprising lOOparts. This combination will make a very strong pe ifume and it is evident that the foregoing formula represents only a single illustration of a perfume made with an ester of orthonphthalic acid as I do not Wish to be limited to'the'use of any specific erfumery substances or any specific proportion of same in the solution of the ester or esters of orthophthalic acid.
When used as perfume bases, the odoriferou's material and the base volatilize Very slowly, the -base serving to prevent the too rapidly volatilization of the perfume although slowly and completely volatile.
hat I claim is 1. The combination comprising an ester of ortho-phthalic acid and essential oils. 1 2. The combination comprising a neutral ester of ortho-phthalic acid and essential 01 s.
3. The combination of an ester of ortho; phthalic acid, essential oils and synthetic perfumes.
4. The combination of a neutral ester of ortho-phthalic acid, essential oils and synthetic perfumes.
5. The combination comprising an ester of ortho-phthalic acid and perfumery oils soluble therein.
(3. The combination comprising an ester of ortho-phthalic acid and odoi'iferous slightly olatile erfumery substances soluble therein.
In testimony whereof I atfix my signature in presence of two witnesses.
