Patented Dec. 11, 1951 UNITED STATES PATENT OFFICE LIQUID FACE ROUGE Leola Silva, Oakland, Calif.
N0 Drawing. Application December 5, 1949,
Serial No. 131,243
They have been applied in powdered form or compressed into a soft chalky cake and distributed on the skin by alternatively applying a cloth pad to the cake and to the face. These materials have obvious disadvantages in use: they are easily brushed from the skin and either water or perspiration cause a rapid deterioration of a coating of these materials on the skin and reduce it to an uneven, frequently streaked or mottled surface of unpleasant appearance.
These disadvantages have been recognized but not remedied and the smooth surface and color tone desired by users of these materials can be maintained only by frequent application of the solid rouge to renew the surface.
I have found that these disadvantages of a solid rouge may be substantially completely overcome by compounding and applying a liquid rouge consisting essentially of an aqueous solution of certain combinations of dyes. This rouge is applied in liquid phase and upon evaporation of the solvent, predominantly water, leaves a thin film of the dyes on the surface of the skin. This film adheres strongly to the skin and is not disturbed by rubbing or brushing. Further, though the dyes of my composition are water soluble the dye film deposited on the skin surface upon evaporation of the solvent component of the liquid rouge is not disturbed or removed by perspiration nor does the flow of water over the skin surface appreciably affect the film. On the other hand the degree of fastness of the dye film is such that it is readily removed by gentle Washing with soap and water. A single application of my liquid rouge lasts through an entire day or evening without deterioration in appearance even under extreme conditions of temperature and humidity. This degree of permanence in the rouge film is highly desirable since a liquid rouge requires a reasonable degree of care and reasonable physical facilities for its application and cannot be casually applied by dabbing with a pad or puff after the manner of solid rouges.
The liquid rouge of my invention consists essentially of an aqueous solution of two color components. The first component is a coal-tar dye till naphthylazo) 2 naphthol-3, fi-disulfonic acid also known as amaranth, the disodium salt of 2 (5-sulio-2, -xylylazo) -1-naphthollsulfonic acid also known as Ponceau SK, and the disodium salt of l-pseudocumylazo-2-naphthol-3, ii-disulfonic acid also known as Ponceau 3B. The second color component of my composition is disodium-2,7-dioromo 4 hydroxymercuri-fluorescein also known as Mercurochrome. The Mercurochrome is present in the liquid rouge at a concentration in the range 0.003 to 0.2 percent by weight and the coal-tar dye is present in amounts from to 3 times the amount of liiercurochrome. In addition to the color constituents of the rouge a small amount of perfume or scent sulficient to impart a definite and pleasant aroma is desirably added. Commercially available perfumes or colognes may be employed for this purpose. While water may be used as the solvent for the dyes it is preferred to employ water alcohol mixtures containing a major proportion of water and a minor proportion of alcohol. The alcohol lowers the surface tension of the liquid rouge. Five to ten percent of ethyl alcohol is ordinarily a suitable alcohol content. The inclusion of alcohol facilitates the application of the liquid rouge so as to obtain a coating presenting a gradual color transition from the unrouged portion of the skin to the most heavily rouged portion.
The following examples are illustrative of the compositions of my invention.
