Definitions

• One of the commonest methods consists in subjecting the body to the action of an ultra-violet ray lamp, which excites the natural pigmentation.
• 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.
• 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.
• 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.
• 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.
• the treatment composition includes one or more substances capable of protecting the skin against the action of ultra-violet radiation.
• 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.
• 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.
• 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.
• 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
• Example II 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.
• 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.
• Example III A cream is prepared from:
• a solution is prepared from: a T Erythrulose'.. I g '3 Propylencglycol g 0.2 Ethyl alcohol 99.8% q.s. cc .100
• composition is an aqueous solution of erythrulose.
• composition is an aqueous-alcoholic solution of erythrulose.
• Example VI A solution is prepared as follows:' Erythrulose g 3 Cellosolve polyglycol .g 3.5; Carbopol (acrylic polymer) l. ...g..# 0.5
• Triethanolamine q.s. for pH 7.5. a
• composition on release from the can deposits on 4.
• composition contains an absorbent for ultra-violet rays.
• a composition for dyeing the skin a brown shade having an appearance similar to that resulting from exposure to the suns rays, which comprises, 0.5% to 10% erythrulose in a diluent maxim'm harmless to the skin and a propellant packaged in a pressurized container.
• a composition for dyeing the skin a brown shade having an appearance similar to that .obtainedby exposure to the suns rays which comprises; erythrulose having a concentration between 0.5% to 10% in a diluent medium harmless to the skin and an absorbent for ultra-violet rays.
• A' composition for dyeing the skin a brown shade having an appearance similar to that obtained by exposure to the suns rays which comprises; erythrulose having a concentration between 0.5% to 10% in a diluent medium harmless to the skin and a gelifying agent.
• a composition for dyeing the skin a brown shade having an appearance similar to that obtained by exposure tothe suns rays which comprises; erythrulose havinga concentration between 0.5% to 10% in a diluent medium harmless to'the skin and a thickening agent.
• compositions for dyeing the skin a brown shade having an appearancesimilar'to tha tgobtained by ex posure to the suns rays, .which 'com'prises; erythrulose having a concentration between.0.5% to 10% in a diluent 7 medium harmless to the skin' and a propellant;
