Definitions

• ABSTRACT Cosmetic composition for use in treating damaged hair.
• the composition comprises, as the active component a methylol compound of the formula:
• the methylol compound is N,N'-dihydroxymethyl glyoxalurea or N,N'-dihydroxymethyl glyoxalthiourea.
• composition is applied at an acid pH and is advantageously made up in solid form for mixing with water or water-and-alcohol solutions when used.
• compositions are used by impregnating the hair with a mixture thereof and water or water-and-alcohol solution followed by drying with heat.
• the present invention relates to a new .cosmeticcomposition intended for restoration of human hair which has previously been more or less severely damaged.
• compositions which contain polycondensable which contain polycondensable.
• N-methylol nitro compounds These compounds have the characteristic of being able, when acted upon by acid catalysts and heat, to polymerize within the keratin, giving rise to a resin that can strengthen the hair.
• these compounds can be fixed to the keratin by their methylol function and thus create new cross linkages of the keratin fiber,- which also reinforces the hair.
• the present invention relates to cosmetic compositions containing one or more polycondensable methylol compounds as the base or essential component, which reinforce the keratin and moreover present the advantage of being much more soluble in water and in water-and-alcohol solutions than are the methylol compounds which have been previously described for use in this field of application.
• formula X represents either an oxygen atom or a sulfur atom or an NH group
• R and R are identical or different and represent either a hydrogen atom or a lower alkyl radical
• R and R represent either a methyl hydroxy group or a methyl alkoxy group, e.g., methyl alkoxy wherein the alkoxy contains up to five carbon atoms or more.
• the cosmetic carrier of the composition is a solid carrier which offers good solubility in water and in water-and-alcohol solutions.
• the preparation of the composition as a solid is made possible by the substantial solubility of the active compounds which permits them to be very readily dissolved by the user at the time of application.
• the solid form of the composition is advantageous, because the composition can be stored in this way to avoid the risk of degradation of the active compounds which could occur in the course of extended storage of these compounds in aqueous solution.
• the composition of the invention is prepared as an aqueous or water-and-alcohol solution (e.g., water/ ethanol or water/isopropanol) of the methylol compound described above, in a concentration ranging between 0.5 and 12 percent by weight of the active component or components.
• the composition of the invention can also be prepared as a cream, a gel or an aerosol.
• the composition may also contain an acid-reacting compound which allows its pH to be brought to a value between 1.5 and 5.
• N,N -dihydroxymethyl glyoxalurea of the formula:
• composition of the invention may also contain conventional ingredients such as swelling agents, surfactants, penetration agents, or dyes, perfumes, and cosmetic resins.
• the present invention is also concerned with a process for treating the hair, characterized in that the hair is impregnated with a composition such as described above, in liquid or fluid form, the hair also being impregnated with an acid solution if the composition itself does not have an acid pH, followed by drying the hair with the application of heat, the hair being optionally rinsed before drying.
• a solid composition according to the invention and comprising the methylol compound and solid carrier can be mixed with water or a water-and-alcohol solution with acid pH to make a lotion or the like which is applied to the hair directly after mixing.
• the treatment process described above is effected along with a hair-curling operation, the hair being rolled up after impregnation with the composition on curler rolls and dried by the application of heat.
• compositions of the invention in the manner described herein are that, even in the case of hair that has been substantially damaged, there is attained a curl that is of excellent quality, the hair regaining its original softness, sheen and liveliness.
