United States Patent 3,184,388 PROCESS AND PRODUCT FOR ARTIFICIALLY BROWNING THE SKIN Gregoire Kalopissis, Paris, France, assignor to Societe Anonyme dite: LOreal, Paris, France, a French corporate No Drawing. Filed July 24, 1961, Ser. N 125,964 Claims priority, application France July 25, 1960, 833,916, Patent 1,307,259 Claims. (Cl. 16790) This invention relates to a process and product for use in the artificial browning of the skin.

Various methods for imparting a brown coloration to the skin, similar to that which can be obtained by more or less prolonged exposure to the suns rays, have already been in use for a long time.

One of the commonest methods consists in subjecting the body to the action of an ultra-violet ray lamp, which excites the natural pigmentation. However, this method has disadvantages which arise, on the one hand, out of the fact that it necessitates a special installation, and on the other hand out of the fact that it is advisable to control carefully the dosage of radiation received, as otherwise a physiologically deleterious effect may arise.

The present invention is based on the discovery that the compounds erythrulose (butane-1,3,4-triol-2-one) when brought into contact with the skin, dyes the skin in brown shades of variable depth, so that the skin acquires an appearance very similar to that obtained by exposure to the suns rays.

By the use of this compound it is possible to obtain satisfactory browning of the skin within a few hours without any necessity for exposure to the sun.

I According therefore to a first feature of the present invention a process for imparting to the skin a brown coloration similar to that resulting from the action of the sun, comprises applying to the skin a composition comprising erythrulose and a diluent medium therefor.

The diluent medium must be a solvent of'the erythrulose, but must be also harmless to the skin and able to wet and to facilitate the penetration of the erythrulose into the skin. As diluent medium, one can choose glycerol, polyglycol or other non-ionic surface-active compounds such as polyethylene glycols having a molecular weight of from 300 to 2,000 and more.

In accordance with one form of the process of the invention, the treatment composition is an aqueous or aqueous-alcoholic solution of erythrulose of concentration preferably between 0.5% and 10%, the concentration chosen being dependent on the extent of browning of the skin which it is desired to obtain.

A concentration of the erythrulose below 0.5% does not give a suiiicient browning of the skin for commercial purpose.

On the other hand, it is not necessary to incorporate into the solution, more than 10% of erythrulose, since higher concentrations do not increase the browning of the skin obtained with a concentration of 10%.

In a preferred form of the invention, the treatment composition includes one or more substances capable of protecting the skin against the action of ultra-violet radiation. In this way, the application of the composition affords both eifective protection against the suns rays and a rapid coloration of the skin, this coloration being due to a large extent to the action of erythrulose, but to a small extent also to the action of the suns rays.

The treatment compositions may be prepared in the form of lotions, creams or gels and may contain any of the thickening or gelling ingredients known per se for inclusion in cosmetic preparations.

The lotions, creams or gels may be packed in a pressurized container, whereby it is possible to obtain either 3,184,388 Patented May 18, 1965 a very fine dispersion of the solution (aerosol) or an automatic distribution of the cream or of the gel.

According to a further feature of the invention, therefore, there are provided compositions for use in browning the skin which comprise erythrulose together with a diluent medium of such character that the compositions are in the form of creams or gels, or which contain erythrulose, an absorbent for ultra-violet radiation and a diluent medium, the compositions being in the form of lotions, creams or gels.

The following examples will serve to illustrate the invention:

Example I A composition is prepared by mixing 4 g. of erythrulose with sufiicient of 40% aqueous ethyl alcohol to provide 100 cc. of solution.

A layer of this solution is spread on the skin by any means, such as a cotton pad or a brush, and allowed to dry. A light brown coloration slowly develops. If it is desired to deepen the shade obtained, it is sufficient to repeat the operation as many times as desired.

The skin thus treated has a very natural bronzed appearance.

It is also possible to add to the above described solution 2 to 10% of glycerol, polyglycol or non ionic surfaceactive compounds such as polyethylene glycols of a molecular weight from 300 to 2000 and more. The browning of the skin obtained with such solutions is also very natural.

Example II The following composition is prepared: Erythrulose g. 3 Ester of salicylic acid and a polyethyleneglycol g 9 aqueous alcoholic solution, q.s cc

This solution is applied to the skin as indicated in Example I and gives a very natural bronzed appearance, while at the same time the salicylic ester acts as absorbent for ultra-violet rays, whereby the epidermis is protected.

The ester of salicylic acid mentioned in the present example is, of course, not the only compound which can be added to the solution, in order to protect the epidermis against the action of the ultra-violet rays.

One can choose other known compounds such as, for instance, methyl-umbelliferone or methyl-salicylate.

Example III A cream is prepared from:

Lanette wax g 5 Erythrulose g 4 Water, q.s cc 100 Example IV The following composition is prepared: Carbopol g 0.6 Erythrulose g 3 40% aqueous ethyl alcohol, q.s. cc 100 The erythrulose is dissolved in the 40% aqueous alcohol. The solution thus obtained is sprinkled with Carbopol With slow stirring.- The mixture is allowed to swell and there is thus obtained a transparentv gel which can be directly applied to the skin and imparts thereto,

after several hoursfa brown coloration, which can bedeepened by repeating the operation.
