ROBERT E. SHARP, OF CHICAGO, ILLINOIS, ASSIGNOR T0 LILLIAN R. SHARP, DOING BUSINESS AS PERFECT POWDER N 0 Drawing. Application filed December My invention relates to a rouge, such as that used for heightening the color of the skin, and it conslsts in the mixture hereinafter set forth.

Heretofore dry rouge (as distinguished from grease or paste rouge) has been made by using water soluble or spirit soluble color, together with a dry powder, to give to the dry powder the shade required for various complexions, and the manufacturers have always endeavored to make a rouge so that it would appear-to the eye to be the same shade, when applied to the face, that it appeared in the box. This has compelled the dealers to carry a very large stock of the various shades of different manufacturers, in order to fit the many different complexions of their customers.

The ordinary dry rouge, being made of colored powder, will wash off or streak, and therefore requires repeated applications. The color on the face of the user of the ordinary rouge is exactly the shade of the colored powder, regardless of the complexion of the individual using it. This makes it quite an artistic undertaking for the woman to select a shade that will fit her complexion. i 7

An object of my invention is to provide a rouge which will; fit any complexion, from r the darkest brunette to the lightest blond.

A further object of my invention is to provide a rouge which-will not wash off except by the use of cold cream or soap.

A further object of my invention; is to provide'a roug gge whichv meets with the natural oil of the face to. renderit effective.

Other objects and advantages will appear in the following'specification, and the novel features of the inventionwillappear in the appended claims. i y,

In carrying out my invention,- I-make-v use of a dry oil-soluble and "water-insoluble;

brilliant red pigment, such,-'for,, instance,

amidoazobenzol-B naphtol o-amidoazotoluol-B naphtol, listed as number" 223 and 232, respectively, in Schultz on Dyestufl's, German edition 1914:. The particles of this pigment are infinitesimally small. With this igment I mix a dry white powder, the'su stance of which is equally fine and free from grit. The powder which I prefer is powdered silica that has been air and water floated. Such powder is impal- PUFF 00., or CHICAGO, ILLINOIS.

pable, pure, and free from any oily or soapy substance.

In practice, I thoroughly mix six ounces of the pigment with twenty pounds of the white powder. There is no change in the consistency of the dry oil-soluble pigment after it has been mixed. At first, the mixture is white, but in a few days it changes to a faint lavender or orchid tint. I The reason for this appears to be that when the powder and the pigment are first mixed, the small particles of the color are not entirely distributed over the small particles of White powder, so that the characteristic color, i. e., white, is from the predominating surface of the white powder. In a few days the cohesive attraction of the small particles of pigment bring them together, thereby covering the surface of the white powder and giving the latter a thin coating of the dry color, which, together with the white body of the silica, has a lavender or an orchid tlnt.

It will be seen that with this powder there are two substances, both extremely fine, the particles of which are held together by cohesive attraction, but neither of which has any chemical affinity for the other. The result is that if this powder is rubbed on the face, the small particles of the dry pigment are instantly soluble in the thin film of oil that covers the skin, and the small particles of dry powder are brushed on" of the skin. Therefore the thin film of oil covering the skin has been colored a bri]liant're l.- This color is so exceedingly thin that the light rays reflected from the skin show just a brightening of the skin, without changing the complexion.

Now since the color of an object is not a property of the object, but rather depends upon the light coming from the object, it

v will be apparent that the color which results from the application of my improved rouge to the skin depends upon the complexion of the skin, so that although two persons might apply the rouge in the same manner, the resulting color to the portions to which the rouge has been applied may be quite different. This is not true of the application of the ordinary rouge, because the ordinary rouge is an opaque powder, and the rouge from the same box will have the same color on persons of different complexions.

It will thus be seen that the rouge which forms the subject of the present invention really gives to the face a thin film, through which the light from the skin will pass, and which will give an effect of heightened color, because of the thin film of red material.

As stated before, the ordinary powder will wash off. But the thin film of red coloring matter, which is oil-soluble, will not wash off, except by the use of an oil removing material, such as cold cream or soap. This obviates ,the necessity of frequent applications, such as are necessary with the ordinary rouge, and such as can often he observed.

While I have specified a toluol and beta naphthol red as the preferred oil-soluble pig- -ment, and powdered silica as the preferred white powder, other oil-soluble pigments, such as vegetable red or other white powders, such as chalk or zinc stearate, may be used to obtain a fair result. contemplate the use of any ingredients which will attain the results set forth, i. e., the production of a rouge. which will fit I thereforeany complexion, owing to the solubility of the color and the thin film which forms on the skin, and through which the color of the skin is visible.

I claim: x

1. A face rouge comprising a mixture of an oil-soluble red pigment which is insoluble in water, and a dry white inert powder.

2. A face rouge, comprising a white powder consisting of fine particles, the particles of said white powder having a relatively thin roating of an oil-soluble. pigment which is insoluble in water.

3. A face rouge. comprising a mixture of an oil-soluble red pigment insoluble in water, and a dry white powder in substantially the proportions of six ounces by weight of the pigment to twenty pounds by weight of the white powder. I

4. A face rouge, comprising a mixture of an oil-soluble red pigment which is insoluble in water, and powdered silica.
