Definitions

• a cosmetic composition for treating hair comprising an electrophile methylol amine and a urein compound, one or both of which contain a chemical group-which has cosmetic properties; and a method of treating hair with this composition.
• Y(NH(l'TNHz)n .s .a.A Y-. X in which n 1 or 2, X is O, S or NH and Y is a disulfide, carboxylic acid, tertiary or quaternary amine or SH group which has cosmetic properties.
• This invention relates to a cosmetic composition which ,makes it possible to improve the condition of human hairand to impart thereto certain properties which are useful when it is to be subjected to a subsequent cosmetic treatment.
• compositions comprising methylol products which are more stable than dimethylolurea and dimethylolthiourea be used, which products yield excellent results due to polymerization in'the keratin chain and condensation of these compounds on the reactive groups of the keratin, thereby in practice imparting to the treated hair greater strength, an improved appearance and, in general, attractive cosmetic properties.
• This phenomenon is particularly valuable when the compound of the urein type contains a cosmetic component attached to the nitrogen which is finally embedded inside the hair when the methylol compounds are polymerized in the keratin in the presence of these particular urein compounds.
• R represents either hydrogen, or a lower alkyl radical
• E represents a radical which is sufficiently electrophile to assure that the entire g'rou molecule
• E is selected from among the following groups:
• urein-type compounds which may be used in the cosmetic compositions according to the invention are:
• the number of urea groups carried by the urein-type compound lies between 0.2 and 3 times and preferably from 0.5 to 1.0 times the number of hydroxyrnethyl or alkoxy methyl groups carried by the methylol compound.
• the composition also contains an acid catalyst, which may bea rnineralor organic acid used in the cosmetic fieldor a salthaving anacid reaction.
• an acid catalyst which may be a rnineralor organic acid used in the cosmetic fieldor a salthaving anacid reaction.
• composition according to the invention may take the form of an aqueous or hydroalcoholic solution and serve as a setting lotion which may comprise any additives conventionallyincluded in such lotions
• the composition according to the'invention may also .take the form of a gel or cream, or be packaged in aerosolf'orm.
• composition according to the invention may also contain any ingredients conventionally used incosmetics, such as dyes, perfumes, surface-active agents, swelling agents, resins, etc.
• the composition may be packaged in two phases, a solid phase containing the methylol compounds, and the urein-type compounds, and a liquid phase which is an aqueous or hydroalcoholic solution, which may contain conventional cosmetic additives and/or an acid catalyst.
• the solid phase contains only the methylol compounds, and the urein-type compounds are in aqueous or hydroalcoholic solution.
• the cosmetic composition according to the invention is prepared at the moment of use by dissolving the solid phase in the liquid phase. This rnethod of packaging makes it possible to avoid the premature polycondensations which may take place during prolonged storage of the composition.
• the solid phase or the aqueous phase of the cosmetic composition packaged in this manner may also contain a salt of sulfurous acid, such as sodium metabisultite.
• a further object of the present invention is to provide a method of treating hair characterized by the fact that the hair is impregnated with the above-described composition, and then dried by heating, after having first been rinsed.
• the cosmetic composition does not itself contain the acid catalyst necessary to bring about polycondensation of the methylol compounds and the urein-type compounds in the keratinic fiber, and this acid catalyst is instead applied to the hair either before or after the composition according to the invention.
• lt is a further object of the present invention to provide the new article of manufacture .which consists of a compound responding to the following formula:
• X represents hydrogen, sulfur, or an NH radical
• Y is a. radical comprising a chemical-functionwhich enables it to serve a cosmeticrpurpose such, for example, as a disulfide function, a carboxylic acid function, a tertiaryor .quatemary amine function, a .fatty chain, or an SH function.

• a further object of the present invention is to provide a new method of preparing urein-type compounds as described above, characterizedby the fact that a cyanate or an alkaline thiocyanate .is reacted with amine compounds having a Y- grouprepresenting the cosmetic additive in question attached to the nitrogen.
• the amine which carries the cosmetic additive attached to its nitrogen atom is reacted .with urea, to produce the corresponding urein by elimination of ammonia.
• a tertiary amine having a cosmetic additive attached to its nitrogen atom is reactedwith a halogenoalkylurea.
• EXAMPLE 1 An aqueous solution of the following composition is applied to natural hair which has first been washed and dried:
• the hair is then set in aconventional manner by winding it up on rollers and drying it under a hood at a temperature of 45 -50 C. This attaches to the keratin of the hair an acid compound having the following statistical formula:
• This operation permits the attachment to the keratin of a compound of the disulfide typewhich is soluble in reducing media and has substantially the following composition:
• n lies between 0.5 and l inclusive.
• the hair is strengthened and the set holds well and is sprin- 8% Moreover, the presence of artificial disulfide bonds in the kcrutinic libcr makes it possible to subsequently permanently wave or bleach the hair under improved conditions.
