Definitions

• This invention relates to a process of making lip rouges for use in lipsticks and to new products which may be used in this process.
• Bromo acids commonly known as eosine acids and as alkaline eosines, are currently used to color lip rouges of the type used in lipsticks.
• the acid eosines are insoluble in water and in fatty substances so that, when used in lipsticks, those colorants must be incorporated into dispersions in the waxes and fatty substances constituting the inert portion or base of the lip rouge.
• This dispersion may be formed by introducing eosine acids into a solvent therefor which is also soluble in the base material of the lip rouge, so that after evaporation of the solvent, the eosine acids precipitate, and, at the end of the process, are dispersed within the material making up the lipstick.
• This dispersion may also be effected by prolonged grinding of a mixture containing the material making up the lipstick and the colorants.
• Colored pigments may also be incorporated into the lipstick material by first dissolving them in a solvent such as glycol or tetrahydrofurfuric alcohol.
• Alkaline eosines are soluble in water, but are not soluble in fatty substances, so that they must also be introduced into the lipstick material in the dispersed state.
• these lip rouges have the practical disadvantage that the color of the lip-stick differs from the color which is imparted to the skin by the application of the lipstick thereto. This is a practical disadvantage which cannot be ignored because it makes it impossible to choose a color by simply looking at the lipstick, so that it is necessary to apply a streak from the lipstick to the skin in order to determine its actual effect in terms of color.
• lip rouges utilizing bromo acid colorants also suffer from the disadvantage that they change color with the passage of time, after having been applied to the skin, and this disadvantage is quite serious because the color tends to shift toward blue, a color which is not considered esthetic in this context.
• the present invention relates to a method of manufacturing new lip rouges from colorants derived from bromo acids and, in particular, for eosines, which avoids all the above disadvantages While providing shades which compare favorably with those presently known.
• bromo acid dyes which may be used in making the compounds according to the invention are the cosine acids and especially those responding to the following formulae:
• the amines which may be used to produce the amine salts according to the invention are the non-aromatic primary, secondary and tertiary monoamines in which the radicals substituted on the nitrogen comprise a maximum of 6 carbon atoms, which may be separated by one or more hetero atoms, and especially by oxygen atoms.
• the radicals substituted on the nitrogen may be separated from each other or connected together to form a heterocycle. They may also carry functional groups such as hydroxyl groups.
• Another object of the present invention is to provide a method of preparing the above amine salts, which method comprises the step of dispersing the dye in a fatty substance in its molten state, and then adding the corresponding amine and permitting the resulting solution to cool.
• the fatty substance in which the bromo acid dye is dispersed for subsequent salification may be a fatty substance used in the manufacture of make-up or lip rouge.
• a fatty substance used in the manufacture of make-up or lip rouge may be a phospholipide, in particular, soybean lecithin, the employment of which is especially advantageous in carrying out the process according to the invention.
• Yet another object of the present invention is to provide as a new article of manufacture a new colored cosmetic composition, and especially a lip rouge or make-up, which contains at least one fatty constituent in which at least one amine salt of a bromo acid dye is dissolved.
• the amine salts of bromo acid dyes may be advantageously dissolved in a mixture of waxes such as vegetable waxes, like Carnauba wax, animal waxes like beeswax, or mineral Waxes like ozokerite, and vegetable or mineral oils.
• waxes such as vegetable waxes, like Carnauba wax, animal waxes like beeswax, or mineral Waxes like ozokerite, and vegetable or mineral oils.
• wax and oil generally constitute the bases of lip rouges and make-up preparations, which may also contain other fatty constituents such as lanolin and its derivatives, various vegetable or animal lecithins and their derivatives, and derivatives of ricin or fatty alcohols.
• the lip rouges produced in accordance with the invention may, for example, consist of a mixture of soy bean lecithin, ozokerite, lanolin derivatives, Vaseline oils, and, of course, dyes according to the invention.
• the cosmetic compositions according to the invention may also contain other ingredients conventionally used in cosmetics such, for example, as perfumes.
• the lip rouges and make-up preparations may contain other base materials or pigments in addition to the dyes according to the invention.
• a lip rouge having the following composition is prepared:
• the soy bean lecithin is placed in a corrosion-resistant container, the dye is added, and the mixture kneaded for several minutes at 50 C.
• triethanolamine is added, while keeping the temperature at 50 C.
• the mixture is thoroughly kneaded and the lanolin derivative added, after which the mixture is heated to 75 C.
• the ozokerite is mixed with Vaseline oil.
• This second mixture is heated to 85 C., and then incorporated into the first mixture. It is left for several minutes at 75 C., while stirring gently, the result is a limpid solution, free of precipitate, which, after cooling, forms a lip rouge having excellent coloring properties.
• a method for making a lip rouge composition consisting essentially of a base containing wax, oil and soy bean lecithin and, as a coloring agent therefor, an cosine acid dye selected from the group consisting of JIM 1151' 1'51 llir 0 0 no -011 no -0 n Br ⁇ 0 -Br ⁇ 0 and an amine selected from the group consisting of triethanolamine, 2-arnino-2-methyl-1,3-propanediol, diethanolamine, monoisopropanol amine, trihydroxymethylaminomethane, morpholine and diglycolamine, comprising kneading at 50 C.
• the soy bean lecithin and the dye until a homogenous mixture is obtained, adding the amine and again kneading while keeping the temperature at C., heating in a separate container the wax and oil at 85 C. and incorporating same into the first mixture which has been heated to C., stirring gently for several minutes at 75 C. and then cooling the mixture to form said lip rouge; the amount of said cosine acid dye ranging between about 5-10 weight percent of said soy bean lecithin and said amine being about 26-46 percent by Weight of said eosine acid dye.
