Description

[Detailed description of the invention]

The present invention relates to compositions for carrying out permanent treatments of hair. Conventional methods for permanently treating hair include, in a first step, cleaving the disulfide bonds of the keratin with a reducing agent-containing composition (reduction process) and then, preferably after rinsing the hair, applying a second treatment. An oxidizing composition is applied to the hair under tension to regenerate disulfide bonds (oxidation process,
It is known that the fixing process (also referred to as the setting process) consists of a process in which the hair is brought into the desired shape.
It is also known that this method can be used to create waves in the hair, as well as to straighten the hair or remove frizz. Reducing and oxidizing compositions are well known and can be found in many cosmetological works, in particular E. Sidi and C.
Zv−iak, “Problemes Capillaires, Paris 1966
(Gauthier Uillard edition). The composition used in the first stage of permanent treatment contains, in addition to the reducing agent, additives which can be in the form of a powder for diluting the composition with a lotion, cream, gel or liquid carrier. In the composition used in the first stage, the reducing agent is preferably a mercaptan, and in the composition used in the second stage, the oxidizing agent is preferably hydrogen peroxide or an alkali bromate. It is well known that the methods by which hair can be made permanent have the disadvantage of weakening the hair and spoiling its general appearance. The present invention relates to a composition for use in the above-mentioned method of permanently treating hair, with the object of making the hair softer to the touch, easier to comb and improving its aesthetic appearance. The invention comprises reducing the disulfide bonds of keratin in a first step by applying a reducing composition and then regenerating the disulfide bonds in a second step by applying an oxidizing composition. In a two-part composition for sequential use in a permanent treatment method, the first part comprises a reducing composition containing at least one cationic polymer and the second part comprises at least one anionic polymer. The present invention relates to a composition for permanent hair treatment, characterized in that it comprises an oxidizing composition containing a surfactant. The hair to be permanently treated, of course when the hair is in the desired new shape, must be subjected to stretching in a known manner so as to be able to regenerate the keratin bonds of the hair. In the case of waves, the new shape is obtained by the use of rollers or hair curlers. In the case of hair straightening, the new shape is obtained, for example, by smoothing the hair. In the composition according to the invention, it is desirable that the cationic polymer be stable in alkaline and reducing media, but it is possible to consider treating it separately. Similarly, it is desirable that anionic surfactants be stable in oxidizing media. In some cases it is desirable to prepare the oxidizing composition at the moment of use. When the composition of the present invention is used in a method of waving hair, the reducing composition is applied to wet hair that has been previously wrapped around rollers having a diameter of 4 to 20 mm, or the composition is applied as the hair is wound. , this is 5
After being allowed to act for 60 to 60 minutes, particularly 5 to 30 minutes and thoroughly rinsed, the oxidizing agent composition containing an anionic surfactant is applied to the curled hair. After the composition has been applied for a period of 2 to 10 minutes, the rollers are removed and the hair is thoroughly rinsed and dried. Mechanical deformation of the hair, which can fix the hair in a new shape in the case of straightening or de-shrinking treatments, is generally achieved by polishing the hair after applying a reducing composition with a wide-toothed comb, the back of a comb, or by hand. You can get it.
After a working time of 5 to 60 minutes, especially 5 to 30 minutes, polishing can generally be started again, but after avoiding excessive pulling, rinse carefully and apply the oxidizing or fixative composition for about 2 to 10 minutes. Let it work. Subsequently, rinse the hair carefully. According to one variant of the invention, the oxidation or fixation process is carried out in two phases, namely by first applying the oxidizing composition to the hair and subsequently (with or without tension) applying the anionic surfactant-containing composition. Can be applied and implemented. In fact, it was confirmed that excellent results could be obtained by dividing the second starting period in the same manner. According to the invention, the reducing composition is of the same type as is customary for permanent treatments, ie preferably contains at least one reducing agent, such as a mercaptan, alkali sulfite or bisulfite or ammonium. The composition consists of a solution and generally has a pH of 6.5 to 10. Preferably, the reducing agent is present in the composition at a concentration of 2 to 25% by weight, based on the total weight of the reducing composition. This reducing agent is a reducing agent commonly used in the permanent treatment of hair and can be, for example, thioglycolic acid or thiolactic acid or mixtures of these acids. In this case the concentration of these reducing agents is generally between 2 and 11% by weight. The reducing agent can also be an alkali or ammonium sulfite or bisulfite. In this case the concentration is generally between 2 and 15%. Reducing agents can also be esters of thioglycolic acid or thiolactic acid (eg monothioglycolates of glycerol or glycols), which can be present, for example, in concentrations of 5 to 25% by weight. The reducing agent can also be a salt of cysteine or a derivative thereof, such as the hydrochloride. The pH of the reducing composition is generally obtained with alkaline agents such as ammonia, monoethanolamine, diethanolamine, triethanolamine, alkali or ammonium carbonate- or bicarbonate, and the like. The reducing composition according to the invention may be exothermic, ie, generate some heat when applied to the hair, giving a certain pleasant feeling to the person undergoing the first stage of permanent or straightening. The cationic polymer is generally present in the reducing composition at a concentration of 0.2 to 5% by weight, based on the total weight of the composition. The term "cationic polymer" refers to polycationic polymers in which the majority of the repeating units have tertiary amine- or quaternary ammonium groups, either in the linear chain or in the side chains.

It is described in the specification of No. 4027020. Particularly preferred polymers falling under the above definition are those known under the names: - “ONAMER M”, commercially available from ONYX Chemical, poly(dimethyl butenyl ammonium chloride)-α, ω-Bis(triethanolamine ammonium chloride) - “MIRAPOL A15”, commercially available from Miranol: Besides the reducing agent and the cationic polymer, the reducing composition also contains various ingredients, such as emollients or quaternary ammonium derived especially from lanolin, protein hydrolysates, waxes, opacifying agents,
Flavors, colorants, nonionic or cationic surfactants or treatments may also be included. In the case of straightening or de-shrinking treatments, the reducing composition is preferably in the form of a cream, in particular in the form of a cream, so that the hair remains as stiff as possible. These creams are prepared in the form of "heavy" emulsions based on, for example, glyceryl stearate, glycol stearate, self-emulsifying waxes, fatty alcohols, and the like. It is also possible to use liquids or gels containing thickeners, carboxyvinyl-polymers or copolymers, etc., which "glue" the hair and hold it in a constant shape during the application period. The oxidizing composition according to the invention comprises as oxidizing agent hydrogen peroxide or an alkali bromate or a persalt or a mixture of an alkali bromate and a persalt. The concentration of hydrogen peroxide is 3 to 10 volumes (vrlume) based on the total weight of the oxidizing composition, the concentration of alkali bromate is 2 to 12% by weight and the concentration of persalt is 0.1 and 15% by weight. Can fluctuate. According to the invention, when the oxidizing composition contains anionic surfactants, these are generally present in a concentration of 0.5 to 30% by weight, preferably 1 to 5% by weight, based on the total weight of the composition. In order to completely avoid the phenomenon of instability of anionic surfactants in oxidizing media, the oxidizing composition can be prepared at the moment of use. It should be noted that a distinction must be made between anionic surfactants and polyanionic polymers. Among the various anionic surfactants which can be used in the oxidizing composition according to the invention, mention may be made in particular of the alkali salts, ammonium salts, amine salts or aminoalcohol salts of the following compounds: - alkyl sulfates and alkyl ethers; Sulfuric acid, alkyl-amide sulfuric acid and ether sulfuric acid, alkylaryl-polyether sulfuric acid, monoglyceride sulfuric acid,
Sulfuric acid - alkyl sulfonic acid, alkylamidosulfonic acid, alkylaryl sulfonic acid - α-olefin sulfonic acid - alkyl sulfosuccinic acid, alkyl ether sulfosuccinic acid, alkylamido sulfosuccinic acid - alkyl sulfosuccinic acid - alkyl sulfoacetic acid, alkyl polyglycerol - carboxylate - Alkyl phosphoric acid, alkyl ether phosphate-alkyl sarcosinate, alkyl isethionate, alkyl taurate. (The alkyl group in all these compounds is a chain of 12 to 18 carbon atoms) - oleic acid, ricinoleic acid, palmitic acid, stearic acid, coconut oil acid or hydrogenated coconut oil acid, formula
Polyglycol corresponding to Alk-(OCH ₂ -CH ₂ ) _o -OCH ₂ -CO ₂ H (however, the substituent Alk represents a molecular chain having 12 to 18 carbon atoms, and n is an integer of 5 to 15) ether carboxylic acid. Particularly preferred anionic surfactants are sodium lauryl sulfate, -ammonium,
or mono-, di- or tri-ethanolamine, sodium lauryl ether sulfate oxyethylated with 2 to 3 moles of ethylene oxide, -ammonium, mono-, di- or tri-ethanolamine : α-olefin sulfonates, alkyl sarcosinates and paraffin sulfonates. The oxidizing composition may also include various ingredients, among others stabilizers, preservatives, softeners, opacifiers, fragrances, colorants, sequestering agents, acidifying or alkalinizing agents. When the fixing process is carried out in two stages, first by applying an oxidizing composition and subsequently, optionally after rinsing, by applying an anionic surfactant-containing composition, the oxidizing The respective concentrations of the oxidizing agent and anionic surfactant are the same as described above for compositions using mixtures of oxidizing agent and anionic surfactant. However, various components can be used in the anionic surfactant solution, such as other surfactants or polymers. As a reducing composition, the oxidizing agent composition according to the invention can also be exothermic, i.e. it generates some heat upon application, which on the one hand promotes the regeneration of disulfide bonds and on the other hand gives a pleasant sensation to the person performing the permanent treatment. It can also include things. Compositions of this type for carrying out oxidative (ie fixative) treatments are described in particular in FR 2 179 025. The invention also relates to a composite composition for carrying out the method according to the invention. This composite composition comprises both reducing and oxidizing compositions for sequential application as described above and is placed in a suitable multi-compartment container with instructions for use. Below, some examples of the composition for permanent hair treatment and the method thereof according to the present invention will be shown.
