Abstract

The invention relates to agents for the treatment of keratinous fibres which are frequently in the form of solid agents mixed with water before use. The aqueous solution has particularly good mixing behaviour and very good application properties when the solid agent contains 5 - 80 wt% of a solid inert ingredient, the 20 wt% solution or dispersion thereof in water at 20 °C having a viscosity which does not exceed 500 mPa s. Preferred embodiments are hair dyes and hair bleaching agents. The invention also relates to a special method for producing said solution and a commercially-used unit appropriate for said method.

Description

"Solid agent for the treatment of keratin fibers"

The invention relates to solid agents for the treatment of keratin fibers, in particular human hair, their use and methods for the treatment of keratin fibers and for the preparation of an application solution and a sales unit for the application of the production method.

Keratin fibers are to be understood here as furs, wool, feathers and in particular human hair.

The number of products which are used as aqueous mixtures but nevertheless reach the consumer in solid form has been increasing more and more recently. There are a number of reasons for this. One reason is that the products can be traded in a compact form without the water that is present everywhere. This leads not only to savings in warehousing and transport capacity, but generally also to less packaging effort. Another reason is that in the case of solid, appropriately packaged products, preservation can generally be dispensed with. This is particularly appreciated by consumers who, for example due to allergies, want to limit the number of ingredients contained in the products they use, in particular their personal care products, to an absolute minimum. Finally, a number of cosmetic active ingredients, in particular of natural origin, have been made available recently, which are in liquid, in particular whose aqueous, packaging does not have the storage stability required for consumer products.

In addition to these undeniable advantages, solid products also have some disadvantages. In particular, the effects of water vapor or atmospheric oxygen in the case of packaging that is not hermetically sealed, on the other hand, can lead to a deterioration in the flowability and ultimately to a so-called "caking" of the individual solid particles. This affects not only the aesthetic perception of the user but makes precise dosing difficult and often leads to poor mixing behavior if the agent is to be dissolved again in water, but the user will only accept such solid products if the application solution can be prepared simply and quickly .

The object was therefore to provide these solid agents in a form which precludes “caking” in the case of long storage and enables the application solution to be prepared quickly without negatively influencing the properties of the product.

It has now been found that the addition of solid, inert constituents which are distinguished by only a slight increase in viscosity in aqueous solution or dispersion remedies the disadvantages mentioned to a surprisingly high degree. This applies both to agents that are in powder form and to agents in granulate form. However, the effect achieved is particularly high with powdered formulations.

The invention thus relates to solid agents for the treatment of keratin fibers, in particular human hair, which contain 5 to 80% by weight of a solid, inert Contain component, the 20 wt .-% solution or dispersion in water at 20 ° C has a viscosity that exceeds 500 mPas.

The "composition" or "composition according to the invention" hereinafter refers to the solid composition before mixing with water.

The ready-to-use preparation obtained after mixing with water, which is finally applied to the keratinic fiber, is referred to as the "application solution".

The agents according to the invention are in solid form. This can be, for example, in the form of a powder or a granulate, with powders generally being preferred. Furthermore, the agents according to the invention can be packaged both in the form of a single preparation and in the form of several preparations which are mixed shortly before use.

All viscosity data refer to measurements with a Brookfield RVF viscometer (spindle 1) at 20 revolutions per minute.

Such inert constituents have proven to be particularly suitable, their 20% solution or dispersion in water at 20 ° C. having a viscosity of at most 100 mPa s, in particular at most 20 mPa s. If the processing temperature of the agents according to the invention is above room temperature, the inert constituents should be chosen so that the viscosity of the corresponding application solution at this temperature is not more than 1.5 times the viscosity of this solution at room temperature. Furthermore, particularly good agents were obtained when the amount of the inert component was 10-60% by weight, based on the total agent. The agents according to the invention contain an inert component as a mandatory ingredient. Of course, the invention also includes agents which contain a plurality of inert constituents which satisfy the conditions mentioned, the total proportion thereof not exceeding 80% by weight of the agent.

According to a first preferred embodiment, the inert component is an organic compound or a mixture of organic compounds. For example, starch, wood, tannic acids, tannin, monosaccharides, oligosaccharides, waxes, chitin, chitin derivatives such as chitosan, polyamides, polyethylenes, polytetrafluorethylenes, synthetic resins and shellac have proven suitable organic compounds. Starch, wood, tannic acids, tannin, monosaccharides, oligosaccharides, waxes, chitin, chitin derivatives such as chitosan and polyamides, polyethylenes and polytetrafluoroethylenes with grain sizes below 500 μm are preferred.

Starch is particularly well suited as an inert component for the agents according to the invention. In principle, the origin of the starch is of no importance for the usability in the agents according to the invention. For example, it can be rice starch, corn starch, potato starch or wheat starch. It is crucial, however, that the starch is selected so that it meets the above-mentioned viscosity criteria. This is particularly the case with starches whose adhesive content is less than 2% by weight. With some special types of starch it may be necessary to reduce the adhesive content to less than 0.5% by weight. An indication of this is the so-called gelatinization temperature, which should be above 55 ° C. for the starches to be used according to the invention.

According to a second preferred embodiment, the inert component is an inorganic compound. Suitable inorganic compounds are, for example, talc, silicates, zeolites, baked clays, kaolin, Diatomaceous earth, chalk, magnesium carbonate, sodium sulfate and sodium chloride. Talc, kieselguhr, chalk, sodium sulfate and magnesium carbonate have proven to be particularly suitable

Free-flowing problems occur, inter alia, with solid agents which contain phospholipids such as lecithm, protein hydrolyzates or their derivatives or else hygroscopic compounds, such as polymers based on cellulose. According to a preferred embodiment, the teaching according to the invention is applied to such agents which contain one or more of these compounds

According to a preferred embodiment, the agents according to the invention are hair treatment agents. In principle, all types of hair treatment agents that can be formulated on an aqueous basis, ie with water as the sole or predominant solvent, are suitable. These are, for example, shampoos, hair treatments, hair lotions, Hair lotions, styling preparations, hair colorants, hair toners, bleaching agents and agents for permanent shaping of hair. The teaching according to the invention has proven to be particularly advantageous for those hair treatment compositions which are usually rinsed out of the hair. Hair colorants, hair toning agents, bleaching agents and hair treatments are therefore particularly preferred agents according to the invention

If the agents according to the invention are hair dyes or hair toners, they contain at least one synthetic or natural dye

According to a preferred embodiment, these agents contain at least one natural dye. According to the invention, natural dyes are those dyes which are derived from natural products with conventional physical Separation processes have been obtained and more chemically modified. Such substances, which are also known as natural dyes, are, for example, henna red, henna black (Indigofera argentea), henna neutral, chamomile blood, sandalwood, black tea, rotten tree ends, sage, blue wood, madder root, catechu , Sedre and Alkanna Root Preferred natural dyes for the agents according to the invention are henna red, henna black, henna neutral, chamomile blood, sandalwood and black tea. The natural dyes in the colorants according to the invention are usually in amounts of about 1-60% by weight. %, preferably in amounts of 5-40% by weight

In a preferred embodiment, the colorants and toning agents according to the invention contain only natural dyes as coloring components. However, it is also possible to add conventional synthetic oxidation dye precursors, so-called developer and coupler components, and / or direct dyes in preferred minor amounts to these agents ben

For example, primary aromatic ames with a further free or substituted hydroxyl or amino group in the para or ortho position, diaminopyndmdenvates, heterocyclic hydrazones, 4-aminopyτazolonde derivatives and 2,4,5, 6-tetraammopynmid and their derivatives can be used as developer components Special representatives smd, for example p-toluenediamine, 2,4,5,6-tetra-aminopynmid, p-aminophenol, N, N-Bιs- (2-hydroxyethyl) -p-phenylendiamine, 2- (2,5-diminophenyl) - ethanol, 2- (2,5-diammophenoxy) ethanol, 1-phenyl-3-carboxyamido-4-anuno-pyrazolone-5 and 4-amino-3-methylphenol, 2-hydroxy-4,5,6-tnamιnopynmιdm, 2,4-Dιhydroxy-5,6-dιamιnopynmιdm and 2,5,6-Trιamιno-4-hydroxypynmιdιn M-Phenylenediammdenvate, Naphthole, Resorcm and Resorcmdenvate, Pyrazolone and m-Ammophenole are preferably used as coupler components.

The developer and coupler components can generally be used in free form. For substances with anuno groups, however, it may be preferred to use them in salt form, in particular in the form of the hydrochloride and hydrobromides. It is also preferred to use such oxidation dye precursors which, due to air oxidation alone or in the presence of suitable enzymes in combination with the corresponding substrates, enables the corresponding colorations even in the absence of larger concentrations of hydrogen peroxide

Direct dyes which can be used according to the invention are, for example, nitrophenylenediamines, nitroaminophenols, anthraquinones or indophenols, such as those known under the international names or trade names HC Yellow 2, HC Yellow 5, Basic Yellow 57, Disperse Orange 3, HC Red 3, HC Red BN, Basic Red 76, Basic Brown 17, HC Red 1, HC Orange 1, 3 - [(2-Nιrro-4- (tnfluoromethyl) phenyl) amme] - 1, 2-propanediol, N- (2-hydroxyethyl) -4-methyl 1-2-nitroamlm, 4-ethylarmno-3-mtrobenzoic acid, HC Blue 2, Disperse Blue 3, Basic Blue 99, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9, Basic Brown 16, Picramic Acid and Rodol 9 R known compounds and 4-amino-2-mtro-diphenylamine-2'-carboxylic acid and 6-nitro-l, 2,3,4-tetrahydroquinoxane It is not necessary that the oxidation dye precursors or the direct dyes each represent uniform compounds. Rather, in the colorants according to the invention, due to the production processes for the individual dyes, further components may also be present in minor amounts, provided that these do not adversely affect the coloring result or must be excluded for other reasons, for example toxicological reasons.

The synthetic oxidation dye precursors or substantive dyes are preferably present in the colorants according to the invention in amounts of about 0.1-10% by weight.

Zwitterionic surfactants are those surface-active compounds which carry at least one quaternary ammonium group and at least one -COO - or -S0 ₃ group in the molecule. Particularly suitable zwitterionic Surfactants are the so-called betaines such as the N-alkyl-N, N-dimethylammomium glycinate, for example coconut alkyl dimethylammonium glycinate, N-acylaminopropyl-N, N-dimethylammonium glycinate, for example coconut acylamino propyl dimethylammonium glycinate, and 2- Alkyl-3-carboxymethyl-3-hydroxyethyl-imidazolines each having 8 to 18 carbon atoms in the alkyl or acyl group, and also the cocoacylammoethylhydroxyethylcarboxymethylglycinate.

Addition products of 2 to 30 moles of ethylene oxide and / or 0 to 5 moles of propylene oxide with linear fatty alcohols with 8 to 22 carbon atoms, with fatty acids with 12 to 22 carbon atoms and with alkylphenols with 8 to 15 carbon atoms in the alkyl ¬ group, Ci ₂ - ₂₂ fatty acid monoesters and diesters of adducts from 1 to 30 mol

Ethylene oxide on glycerol,

C _{g 22} alkyl mono- and ogoglycosides and their ethoxylated analogs,

Adducts of 5 to 60 moles of ethylene oxide with castor oil and hardened castor oil,

Addition products of ethylene oxide with sorbitan fatty acid esters Addition products of ethylene oxide with fatty acid alkanolamides.

Particularly suitable nonionic surfactants are C8-C22-alkyl mono- and ohogoglycosides and their ethoxylated analogs. In particular the compounds of the formula RO- (Z) _v .

in which R stands for an alkyl radical with 6 to 22 carbon atoms, Z for a mono- or oligosaccharide, y for a number from 1.1 to 5, or their add-on products with 1 to 10 molecules of ethylene oxide and / or propylene oxide are outstanding suitable non-ionic surfactants. These connections are also characterized by the following parameters:

The alkyl radical R contains 6 to 22 carbon atoms and can be either linear or branched. Primary linear and methyl-branched aliphatic radicals in the 2-position are preferred. Such alkyl radicals are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. 1-Octyl, 1-decyl, 1-lauryl, 1-myristyl are particularly preferred. When so-called "oxo alcohols" are used as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate. The alkyl glycosides which can be used according to the invention may contain only one specific alkyl residue R. Usually, however, these compounds are made from natural fats and oils or mineral oils. In this case, the alkyl radicals R are mixtures corresponding to the starting compounds or corresponding to the respective working up of these compounds.

Alkylpolyglycosides in which R consists essentially of C and C alkyl groups, essentially of C and C alkyl groups, essentially of C to C 16 alkyl groups or essentially of C to C alkyl groups are particularly preferred .

Any mono- or oligosaccharides can be used as sugar building block Z. Sugar with 5 or 6 carbon atoms and the corresponding oligosaccharides are usually used. Examples of such sugars are glucose, fructose, galactose, arabinose, ribose, xylose, lyxose, allose, old rose, mannose, gulose, idose, talose and sucrose. Preferred sugar units are glucose, fructose, galactose, arabinose and sucrose; Glucose is particularly preferred.

The alkyl polyglycosides which can be used according to the invention contain on average 1.1 to 5 sugar units. Alkyl glycosides with y values of 1.1 to 2 are preferred. Alkyl glycosides in which y is 1.1 to 1.4 are very particularly preferred.

Examples of the cationic surfactants which can be used in the hair treatment compositions according to the invention are, in particular, quaternary ammonium compounds. Preferred are ammonium halides such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammomium chlorides, e.g. B. Cetyltrime thylammonium chloride, stearyltimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammomium chloride, lauryldimethylbenzylammonium chloride and tricetymiethylammonium chloride. The quaternized protein hydrolyzates are further cationic surfactants which can be used according to the invention.

Also suitable according to the invention are cationic silicone oils such as, for example, the commercially available products Q2-7224 (manufacturer: Dow Corning; a stabilized trimethylsilylamodimethicone), Dow Corning 929 emulsion (containing a hydroxylamino-modified silicone, which is also referred to as amodimethicone) , SM-2059 (manufacturer: General Electric), SLM-55067 (manufacturer. Wacker) and Abil ^® -Quat 3270 and 3272 (manufacturer: Th. Goldschmidt; diquaternary polydimethylsiloxane, Quaternium-80).

Alkylamidoamine, particularly fatty acid such as under the Bezeich¬ Tego Amid ^® S voltage 18 stearylamidopropyldimethylamine available, are characterized especially by a good conditioning effect by their good biodegradability.

Quaternary ester compounds, so-called "esterquats", such as the dialkylammonium methosulfates and methylhydroxyalkyl dialkoyloxyalkylammonium methosulfates sold under the Stepantex trademark, are also very readily biodegradable.

An example of a suitable cationic surfactant quaternary sugar derivative is the commercial product Glucquat ^® 100, according to CTFA nomenclature a "lauryl methyl Gluceth-10 Hydroxypropyl Dimonium Chloride". The compounds with alkyl groups used as surfactants can each be uniform substances. However, it is generally preferred to start from natural vegetable or animal raw materials in the production of these substances, so that substance mixtures with different alkyl chain lengths depending on the respective raw material are obtained.

In the case of the surfactants, which are addition products of ethylene and / or propylene oxide onto fatty alcohols or derivatives of these addition products, both products with a “normal” homolog distribution and those with a narrowed homolog distribution can be used. “Normal” homolog distribution is understood to mean mixtures of homologs which are obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. On the other hand, narrow homolog distributions are obtained if, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with a narrow homolog distribution can be preferred.

In the event that natural emulsifiers are to be used, for example phospholipids, saponins, tannic acid, bile acids and their derivatives and abietic acid are preferred. Among the natural emulsifiers, the phospholipids such as lecithins, partially hydrolyzed lecithins and cephalins are preferred. Egg and soy lecithin are particularly preferred. The preferred bile acids and their derivatives according to the invention include cholic acid, deoxycholic acid, lithocholic acid and taurocholic acid. According to the invention, the acids mentioned can also be used in the form of their physiologically tolerable salts, in particular their alkali metal and ammonium salts.

Oxidizing agents such as persulfates, chlorites and in particular hydrogen peroxide or its adducts with urea, melamine and sodium borate and these activating enzymes, blowing agents such as propane-butane mixtures, NO, dimethyl ether, CO and air and antioxidants. If the agents according to the invention are in powder form, it may be advantageous to dedust them by the methods known to the person skilled in the art. Such methods are described, for example, in EP-OS 560 088 and the older German application 195 00 216.8, to which express reference is made. Otherwise, the agents according to the invention can be prepared by simply mixing the corresponding components using the methods known to those skilled in the art.

The preparations referred to as the application solution are usually prepared from the agents according to the invention by adding water. The usual proportions of water: agent according to the invention are 1: 1 to 20: 1, in particular 2: 1 to 10: 1. Quantities of 3: 1 to 5: 1 can be particularly preferred. The term quantity refers to the masses used.

The “application solutions” can be in the form of a real solution, dispersion, foam or gel. Dispersions and in particular gels are preferred according to the invention.

Another object of the invention is the use of a solid agent which contains 5-80% by weight of a solid, inert constituent, the 20% by weight solution or dispersion of which in water at room temperature has a viscosity which does not exceed 500 mPa s exceeds, for the treatment of keratin fibers, especially human hair.

The invention also relates to a process for the treatment of keratin fibers, in particular human hair, characterized in that an agent according to one of Claims 1 to 13 is mixed with water or an aqueous solution and applied to the hair. To prepare an application solution for the treatment of human hair, the solid, powder or granular agent is poured into a container, for example a bottle. A liquid, preferably water, in particular warm to hot tap water, is then poured into the container in the ratio appropriate for the desired application solution. Finally, the application solution is prepared by shaking the container. The application solution which is now ready can then be applied to hair in the customary manner. Such a method is also the subject of the invention.

Finally, the invention provides a further development of a sales unit, in particular a folding box, containing a bottle-like body with a volume corresponding to a quantity of application solution to be treated for the treatment of human hair and an amount of solid, powdered or granular agent adapted to the quantity of application solution to be prepared for use of the manufacturing process in which the amount of solid, powder or granular agent is contained in the bottle-like container. In such a sales unit, the solid agent is already filled in by the manufacturer in the bottle-like container provided for the preparation of the application solution. The user no longer has to pour the solid, powder or granular agent into the container. He only needs to fill the container with water and can then prepare the application solution by shaking it.

While the compositions according to the formulations of type V2 showed clear signs of caking after storage for one month at 45 ° C. in a sealed glass bottle, the compositions according to the formulations of type B2 were still free-flowing.

In each case 12 g of the formulations of type V2 or 20 g of the corresponding formulations of type B2 or B3 were mixed with 60 g of lukewarm water to form a homogeneous gel. The three formulations, each of which was analogous, showed comparable viscosities and comparable application properties in the half-side test and comparable results both in terms of color and in terms of combability, softness and gloss of the hair.

Here too, the recipe according to the invention had a significantly more homogeneous structure and could be mixed in a shorter time to form an application-compatible slurry
