Description

Cosmetic products with protein disulfide isomerase

The invention relates to a method for the enzymatic treatment of keratin fibers, in particular human hair, with cosmetic agents which contain the enzyme protein disulfide isomerase, and to the enzyme-containing agent used in this method and its use for the care of keratin-containing fibers and / or in combination with one permanent deformation of the fibers.

The cleaning and care of the hair is an important part of human body care. Both cleaning the hair with shampoos and the decorative design of the hairstyle, for example by dyeing or perming, are interventions that influence the natural structure and properties of the hair. After such a treatment, for example, the wet and dry combability, hold, fullness, shine and tactility of the hair can be unsatisfactory. In addition, the hair is damaged by environmental influences such as UV, IR radiation and heat, e.g. B. by blow drying the hair.

To maintain and restore the aforementioned properties, it has therefore long been customary to subject the hair to a special after-treatment. The hair, usually in the form of a rinse, is treated with special active ingredients, for example quaternary ammonium salts or special polymers. Depending on the formulation, combability, hold, fullness, shine and feel of the hair are improved. For the temporary influencing of the hair volume, the use of polyaminoglucoses as in EP-A-0412745 and US-A-5,523,078, of cellulose as in JP-A-04124121 and EP-A-0823252 and alkylcellulose in WO-A-97/38673 , US-A-5,534,247 and WO-A-94/06410. Smaller carbohydrate components such as glucose in WO-A-95/00104, maltose in WO-A-95/00104 and lactose in DE-A-19610458 are also used. at However, the application of such rinses leaves only a relatively small proportion of the active ingredients at their place of action. The majority is rinsed off immediately or detached from the hair surface by later washing the hair or mechanical stress, such as combing.

Treatment of material containing keratin, e.g. Wool with protein disulfide isomerase is described in the publications EP-B1-276 547 and EP-B1-276 781.

US-A-3,619,114 teaches the permanent modification of keratinous substrates by copolymerization with vinyl monomers in the presence of radical catalysts and subsequent treatment with aqueous ammoniacal copper hydroxide solutions. Due to the toxicity of the compounds used, the application is limited to inanimate keratin fibers. US-A-2, 615,782 teaches the modification of keratinous fibers by forming disulfide bridges between hair and active substance. Another method for fixing compounds which serve to permanently shape hair and which is particularly aimed at permanent wave processes is the use of so-called colored salt derivatives, as described in DE-A-3735086, DE-A-4109869 and EP-A- 0246151. US-A-3,415,606 teaches the use of reactive dyes which have a long-term effect on the hair.

It is therefore of urgent interest to fix protective, restorative and restructuring agents preferably permanently on the hair and at the same time to avoid polluting the environment and harming the health of the user.

The object of the present invention is to provide an agent and a method for the treatment of fibers containing keratin, with the aid of which care and restructuring of the fibers can be effected. By the The method according to the invention enables care of the fiber and, if appropriate, simultaneous deformation of the fiber.

A first subject of the invention is therefore an agent for the cosmetic treatment of keratin fibers, in particular human hair, which contains at least one enzyme of the protein disulfide isomerase type (EC 5.3.4.1) and is free of carbohydrate derivatives with at least one disulfide group (-SS-) or thiol group (-SH).

Enzymes are classified according to the official Enzyme Nomenclature of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB) with EC number (Enzyme Commission). A complete list of characterized enzymes from the enzyme classes according to IUBMB can be found in the SwissProt database at http://www.expasy.ch.

Enzymes from the enzyme class EC 5.3.4.1 (official name: protein disulfide isomerase) preferentially catalyze the isomerization of intermolecular and intramolecular disulfide bonds in proteins.

Suitable are, for example, protein disulfide isomerases which are obtained from bovine liver or E. coli or enzymes with disulfide isomerase activity which are accessible by recombination, as are described, for example, in US Pat. No. B1 -6,387,683, to which reference is expressly made here.

Aqueous, alcoholic and oily preparations and mixtures thereof are particularly suitable according to the invention. Aqueous preparations are preferred. In the context of the invention, aqueous preparations are understood to mean those compositions which contain at least 10% by weight of water, based on the total composition. For example, solutions, dispersions, emulsions (water in oil emulsions, oil in water emulsions as well as multiple emulsions and PIT emulsions). Furthermore, it is also possible to formulate the agent according to the invention as a two-phase or multi-phase system in which the separated phases are mixed by mechanical movement shortly before use to form a metastable dispersion. The dispersion separates into the separate phases a few seconds or minutes after the mixing process.

The pH of the preparations according to the invention is generally 4 to 9, preferably 6 to 8 and particularly preferably 7.3 to 7.7. In a special embodiment for an acidic perm, the pH is less than pH 7, with a tendency in the slightly acidic range until it reaches approximately pH 6. In a special embodiment for a basic perm, the pH of the agent according to the invention is greater than pH 8 and is preferably in the range up to about pH 10.

Bases such as ammonia and organic amine compounds such as e.g. Monoethanolamine, or hydroxides of the alkali metals as well as acids such as e.g. Phosphoric acid, hydrochloric acid or organic acids such as e.g. Acetic acid or edible acids such as citric acid, tartaric acid or malic acid, use.

The enzyme is preferably contained in the agent according to the invention in an amount of 0.1 to 2000 units of enzyme, preferably of 500 to 1500 units of enzyme. U (unit) is the amount of enzyme that 1 unit of unfolded ribonuclease (RNase) can fold (reactivate) within one minute at pH 7.5 and 30 ° C. To measure RNase activity, reduced RNase A from cattle is treated with protein disulfide isomerase in the presence of cCMP (cyclic cytidine monophosphate) and glutathione with PDI. The cleavage of the cCMP by reactivated RNase A is monitored using a spectrometer at a wavelength of 284 nm. This is the reactivation of RNase A by protein disulfide isomerase, for example by an RNase assay from TaKaRa Shuzo Co. Ltd., Biomedical Group, Japan. A description of this measurement method can also be found in Goldberger, RF, Epstein, CJ, Anfinsen, CB (1964) J. Biol. Chem., 239, 1406; Lambert, N. and Freedman, RB (1983), Biochem. J., 213, 225; Hillson, DA, Lambert, N., Freedman, RB (1984), Methods in Enzymology 107, 281; Tang, JG, Wang, CC, Tsou, CL (1988) Biochem. J., 255, 451 and Gething, MJ and Sambrook, J. (1992), Nature 355, 33.

Compounds, for example proteins which carry disulfide bridges or free thiol groups, are preferably used as substrates for the protein disulfide isomerase. The presence of free thiol groups on the substrate promotes the course of the isomerization reaction. It is therefore preferred according to the invention to use the protein disulfide isomerase on the hair in the presence of a keratin-reducing agent. The agents according to the invention contain thioglycolic acid, thiolactic acid, thio malic acid, DL-dithiothreitol, glutathione, mercaptoethanesulfonic acid and their salts and esters, cysteamine, cysteine and salts of sulfurous acid as preferred reducing agents. DL-dithiothreitol or thioglycolic acid are particularly preferred.

In one embodiment, the agents according to the invention contain at least one complexing agent. Suitable complexing agents are, for example, EDTA, NTA, β-alaninediacetic acid, polyphosphonic acids, polyphosphates and organic acids such as citric acid. EDTA or its physiologically compatible salt is a preferred complexing agent in the sense of the present invention. In a further embodiment, the agents according to the invention contain at least one surfactant, in principle both anionic and zwitterionic, ampholytic, nonionic and cationic surfactants are suitable.

A first group of cationic polymers are the so-called “temporarily cationic” polymers. These polymers usually contain an amino group which is present as a quaternary ammonium group at certain pH values and is therefore cationic.

However, among the cationic polymers are the permanently cationic ones

Polymers preferred. According to the invention, polymers which have a cationic group irrespective of the pH of the agent are referred to as “permanently cationic”. These are generally polymers which contain a quaternary nitrogen atom, for example in the form of an ammonium group.

Preferred cationic polymers are, for example, quaternized cellulose derivatives, such as are available under the designations quat Cel ^® and Polymer JR ^® commercially. The compounds Celquat ^® H 100, Celquat L 200 and Polymer JR ^® ^® 400 are preferred square ternierte cellulose derivatives,

The cationic polymers are contained in the agents used according to the invention preferably in amounts of 0.05 to 10% by weight, based on the total agent. Amounts of 0.1 to 5% by weight are particularly preferred.

Ampho-polymers are also suitable as a care substance in combination with or as an alternative to cationic polymers. The term amphopolymer refers to amphoteric polymers, ie polymers that contain both free amino groups and free -COOH or SOsH groups in the molecule and are capable of forming internal salts, zwitterionic polymers that contain quaternary ammonium groups and -COO- - Or -S0 ₃ groups, and summarized such polymers that contain -COOH or SOsH groups and quaternary ammonium groups.

A second subject of the invention is the use of an agent which contains and free at least one enzyme of the protein disulfide isomerase type (EC 5.3.4.1) and at least one care substance with at least one disulfide (-SS-) or thiol group (-SH) is of carbohydrate derivatives with at least one disulfide (-SS-) or thiol group (-SH) in a process for the care and, if necessary, for the simultaneous permanent deformation of keratin fibers, in particular human hair.

The statements made in the definition of the first subject of the invention apply to the preferred embodiments of this agent and to the definition of terms.

A third object of the invention is the use of an agent which contains at least one enzyme of the protein disulfide isomerase type (EC 5.3.4.1) and is free of carbohydrate derivatives with at least one disulfide (-S- S-) or thiol group (-SH ) in a process for permanent deformation of keratin fibers, especially human hair.

A fourth object of the invention is a process for the treatment of keratin-containing fibers, in particular human hair, in which i) the previously described enzyme-containing agent according to the invention is applied to the optionally moistened fibers, ii) the agent is left on the fibers for an exposure time iii) and the fibers be subjected to post-treatment. The statements made in the definition of the first subject of the invention apply to the composition of the enzyme-containing agent according to the invention and the relevant embodiments.

The fiber can be moistened using various methods. So it is according to the invention to clean the hair before step i) of the method, e.g. Shampoo, subject and terry the hair after cleaning with a towel. In this way, moistened hair is obtained. Furthermore, moistening can be carried out in the course of a pretreatment by an agent M. Agent M can remain on the hair or be rinsed off after a contact time. The action time of the agent M is preferably 5 to 45 minutes.

If used for the pretreatment, the agent M can contain a reducing agent as keratin-reducing substance in a further embodiment of the method. Examples of suitable reducing agents are thioglycolic acid, thiolactic acid, thio malic acid, dithiothreitol, mercaptoethanesulfonic acid and their salts and esters, cysteamine, cysteine, colored salts and salts of sulfurous acid. The alkali metal or ammonium salts of thioglycolic acid and / or thiolactic acid and the free acids are particularly suitable.

In a further embodiment, the agent M contains at least one care substance which contains a thiol group or a disulfide group. Such care substances have a substrate activity for the protein disulfide isomerase. It may be preferred to use the care substance in an amount of 0.001 to 10% by weight, preferably 0.01 to 5% by weight, particularly preferably 0.1 to 2% by weight, based on the total agent , Care substances which are selected from compounds according to the formula are preferably used R ¹ -Y ¹ -G ¹ -XG ² -Y ² -R ² (I)

The post-treatment of the fibers can be carried out in different ways. According to one embodiment, the fibers are merely subjected to a rinse, which can be done with water.

According to a further embodiment, agent M can be used as an aftertreatment agent in the process according to the invention. The agent M is optionally applied to the fiber after an optional intermediate rinsing step. After a residence time of preferably 5-45 minutes on the fibers, the agent M is rinsed off again and the fibers are dried.

It is accordingly possible in one embodiment of the method to apply the care substance with a thiol group or disulfide group and the enzyme in succession to the keratin-containing fiber in any order. In this embodiment, the enzyme-containing agent according to the invention cannot contain a care substance, but agent M, which is used for pre-treatment or post-treatment of the fiber. Although these two-stage processes lead to the desired effects, it may be preferred to process the process according to the invention in a 1-step Process because such a process is easier to use. The care substance with substrate activity is preferably mixed with an enzyme-containing composition immediately before use, and the mixture is then applied to the fiber as a composition according to the invention in a single step.

The method according to the invention can also be carried out in the context of an oxidative hair dyeing process before or after the oxidative hair dyeing. Treatment of the keratin-containing agents with protein disulfide isomerase can have a favorable effect on the coloring properties of oxidative hair coloring and promote the well-groomed appearance of the hair.

In order to achieve a defined hair deformation, in a further embodiment, before the step i) of the method according to the invention, the hair can be wound onto winding aids (curlers, papillots) for mechanical deformation. Experience has shown that the hair can be wrapped particularly well on the changing aids when it is damp. Consequently, the hair should be moistened before or during the introduction of the changing aids. In this embodiment, the fiber can also be moistened with the agent according to the invention.

The enzyme-containing agent according to the invention is rinsed out after an exposure time of 3 to 120 minutes. This rinsing can be done with pure water. Exposure times of 15 to 30 minutes have proven to be sufficient in most cases.

Regardless of the course of the method according to the invention, it has proven to be advantageous to use the enzyme at a temperature of 18 to 55 ° C., in particular 25 to 50 ° C.
