Description

"Hair fixative with derivatized maleic anhydride polymer and amphoteric film-forming polymer"

The present invention relates to hair fixatives containing at least one derivatized maleic anhydride polymer and at least one amphoteric film-forming polymer, and the use of this agent for the temporary deformation of keratinous fibers.

Hair-setting agents for shaping keratinous fibers have been known for a long time and, in various embodiments, are used to build up, freshen up and fix hairstyles that can only be obtained in many types of hair using firming agents. Such agents are also referred to as styling agents, with both hair treatment agents, which serve a permanent, as well as those which serve a temporary shaping of the hair play an important role. Temporary shapes, which should give a good grip, without affecting the healthy appearance of the hair, such as their gloss, can be achieved for example by hair sprays, hair waxes, hair gels, hair drier, etc.

Corresponding temporary shaping agents usually contain synthetic polymers as the shaping component. Preparations containing a dissolved or dispersed polymer can be applied to the hair by means of propellant gases or by a pumping mechanism. Hair gels and hair waxes, however, are usually not applied directly to the hair, but distributed by means of a comb or hands in the hair.

Styling agents have to meet a whole range of different requirements. These may be broadly subdivided into properties on the hair, properties of the particular formulation, eg properties of the foam, of the gel or of the sprayed aerosol, and of properties relating to the handling of the styling agent, the properties of the hair being of particular importance. Decisive, of course, first of all a high setting power, but in addition also moisture resistance, low stickiness and a balanced conditioning effect. Furthermore, a styling agent should be universally applicable as possible for all hair types. In order to meet the different requirements, a large number of synthetic polymers has already been developed, which are used in styling agents. The polymers can be subdivided into cationic, anionic, nonionic and amphoteric film-forming and / or setting polymers. Ideally, when applied to hair, the polymers give a polymer film which, on the one hand, gives the hairstyle strong hold but, on the other hand, is sufficiently flexible not to break under stress. If the polymer film is too brittle, it leads to the formation of so-called Filmpiaken, that is residues that detach during the movement of the hair and give the impression that the user of the corresponding styling agent would dandruff.

In US 2004/0042989 A1 polymers for hair setting agents are proposed, which are characterized by a combination of flexibility and pronounced affinity for keratin fibers. These are polymers based on maleic anhydride copolymers, which are modified by reaction with amine derivatives. The polymers have repeat units which are derived from maleic acid, maleic acid monoester, maleic acid monamide and / or the cyclic maleimide. Styling agents based on these polymers have the advantage that the treated hair feels natural. However, you can not fully convince in terms of moisture resistance and Festigerleistung.

In order to improve the moisture resistance, US 2004/0042987 A1 proposes to use the polymers in combination with a compound or a polymer having a carboxylic acid functionality. As suitable compounds or polymers having a carboxylic acid functionality, only linked acrylic acid polymers are explicitly mentioned. These are components that are commonly used as a thickener and about under the name Carbopol ^® (INCI name: Carbomer) are commercially available. In particular, the setting power can not be significantly improved by the addition of Carbopol ^® .

Object of the present invention was therefore to provide a hair setting agent for temporary shaping available, which is characterized on the one hand by a high setting performance and moisture resistance and on the other hand, that the treated hair feels natural.

It has now been found that this can be achieved by a styling agent containing at least one particular maleic anhydride polymer and at least one amphoteric film-forming and / or setting polymer. Surprisingly, they stay treated hair flexible despite the addition of an amphoteric film-forming and / or setting polymer. There is no tendency for the formation of Filmpiaken.

In other words, these particularly preferred polymers a) are characterized by an isobutyl / maleic anhydride copolymer backbone. Decisive for the advantageous properties of the polymer a) in hair setting agents is its derivatization with a hydrophobic amine, a hydrophilic amine and / or a polyetheramine.

As the hydrophobic amine are suitable for derivatization ounsubstituierte primary or secondary, optionally branched monoamines, which may optionally be substituted by alkyl, aryl, a heterocycle, fluorine, chlorine or silylamine.

In order to obtain the desired properties of the hair setting agent according to the invention, in particular the combination of strong hold, high moisture resistance and flexibility, both polymer a) and polymer b) must be present. It has been found that an optimum property profile results when the hair setting agent contains the polymer a) and the film-forming and / or setting amphoteric polymer b) in a molar ratio of 1:10 to 10: 1. Particularly preferred is a molar ratio of 1: 3 to 3: 1.

The hair setting agent according to the invention can be present in the known application forms. For example, the hair setting agent in the usual manner as Aerosolhaarspray, pump spray, hair gel, hair wax or mousse.

For this purpose, the hair setting agent is preferably present in an aqueous, an alcoholic or in an aqueous alcoholic medium with preferably at least 10 weight percent water based on the total agent. As alcohols, it is possible in particular to include the lower alcohols having 1 to 4 carbon atoms usually used for cosmetic purposes, such as, for example, ethanol and isopropanol. The preparation can be carried out for example in the form of creams, emulsions, gels or surfactant-containing foaming solutions or other preparations which are suitable for use on the hair. The agents preferably have a pH of 2 to 11. The pH range between 2 and 8 is particularly preferred. The pH values in the context of this document refer to the pH at 25 ° C., unless otherwise stated.

As additional co-solvents may be organic solvents or a mixture of solvents having a boiling point below 400 ⁰ C in an amount of 0.1 to 15 weight percent, preferably from 1 to 10 weight percent based on the total agent be included. Particularly suitable as additional co-solvents are unbranched or branched hydrocarbons such as pentane, hexane, isopentane and cyclic hydrocarbons such as cyclopentane and cyclohexane. Further, particularly preferred water-soluble solvents are glycerol, ethylene glycol and propylene glycol in an amount of up to 30 percent by weight based on the total agent.

The hair setting agent may further contain the auxiliaries and additives which are usually added to conventional styling agents.

Particularly suitable auxiliaries and additives are care substances.

As a care material, for example, a silicone oil and / or a silicone gum can be used.

Suitable silicone oils or silicone gums are, in particular, dialkyl and alkylaryl siloxanes, for example dimethylpolysiloxane and methylphenylpolysiloxane, and also their alkoxylated, quaternized or else anionic derivatives. Preference is given to cyclic and linear polydialkylsiloxanes, their alkoxylated and / or aminated derivatives, dihydroxypoly-dimethylsiloxanes and polyphenylalkylsiloxanes.

Silicone oils cause a wide variety of effects. For example, at the same time they influence the dry and wet combability, the grip of dry and wet hair and the shine. The term silicone oils is understood by the person skilled in the art as meaning several structures of silicon-organic compounds. These are first dimethiconols and dimethicones, such as the marketed by Dow Corning under the name Dow Corning ^® 193 Surfactant PEG-12 dimethicones understood. These may be both linear and branched as well as cyclic or cyclic and branched. They furthermore include the dimethicone copolyols, such as are for example sold by the company Dow Corning under the designation Dow Corning ^® 5330 Fluid, and amino-functional silicones, especially the silicones, the name INCI Amodimethicones are summarized under the.

As a conditioner also a cationic surfactant can be used. Cationic surfactants of the quaternary ammonium compounds, esterquats and amidoamines are preferred. Preferred quaternary ammonium compounds are ammonium halides, in particular chlorides and bromides, such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, eg. Cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride and tricetylmethylammonium chloride, as well as the imidazolium known under the INCI names Quaternium-27 and Quaternium-83. Links. The long alkyl chains of the above-mentioned surfactants preferably have 10 to 18 carbon atoms.

Nurturing polymers are also suitable as a care substance.

A first group of caring polymers are the cationic polymers. Cationic polymers are to be understood as meaning polymers which have a group in the main and / or side chain which may be "temporary" or "permanent" cationic. According to the invention, "permanently cationic" refers to those polymers which have a cationic group, irrespective of the pH of the agent. These are usually polymers containing a quaternary nitrogen atom, for example in the form of an ammonium group. Preferred cationic groups are quaternary ammonium groups. In particular, those polymers in which the quaternary ammonium group is bonded via a C _1-4 hydrocarbon group to a polymer main chain constructed from acrylic acid, methacrylic acid or derivatives thereof have proven to be particularly suitable.

A particularly suitable homopolymer is, if desired, crosslinked, poly (meth acryloyloxyethyltrimethylammonium chloride) with the INCI name Polyquaternium-37. If desired, the crosslinking can be carried out with the aid of poly olefinically unsaturated compounds, for example divinylbenzene, tetraallyloxyethane, methylenebisacrylamide, diallyl ether, polyallylpolyglyceryl ethers, or allyl ethers of sugars or sugar derivatives such as erythritol, pentaerythritol, arabitol, mannitol, sorbitol, sucrose or glucose. Methylenebisacrylamide is a preferred crosslinking agent.

Furthermore, cationized protein hydrolysates are to be counted among the cationic polymers, wherein the underlying protein hydrolyzate from the animal, for example from collagen, milk or keratin, from the plant, for example from wheat, corn, rice, potatoes, soy or almonds, marine life forms, for example from fish collagen or algae, or biotechnologically derived protein hydrolysates. The protein hydrolyzates on which the cationic derivatives are based can be obtained from the corresponding proteins by chemical, in particular alkaline or acid hydrolysis, by enzymatic hydrolysis and / or a combination of both types of hydrolysis. The hydrolysis of proteins usually results in a protein hydrolyzate having a molecular weight distribution of about 100 daltons up to several thousand daltons. Preference is given to those cationic protein hydrolyzates whose underlying protein content has a molecular weight of 100 to 25,000 daltons, preferably 250 to 5000 daltons. Furthermore, cationic protein hydrolyzates are to be understood as meaning quaternized amino acids and mixtures thereof. The quaternization of protein hydrolyzates or amino acids is often quaternized Ammonium salts such as N, N-dimethyl-N- (n-alkyl) -N- (2-hydroxy-3-chloro-n-propyl) - ammonium halides performed. Furthermore, the cationic protein hydrolysates may also be further derivatized. As typical examples of the suitable cationic protein hydrolysates and derivatives, those listed under the INCI names in the "International Cosmetic Ingredient Dictionary and Handbook", (7th Edition 1997, The Cosmetic, Toiletry, and Fragrance Association 1101 17 ^th Street, NW, Suite 300, Washington, DC 20036-4702) and commercially available products called: Cocodimonium Hydroxypropyl Hydrolyzed Collagen, Cocodimonium Hydroxypropyl Hydrolyzed Casein, Cocodimonium Hydroxypropyl Hydrolyzed Collagen, Cocodimonium Hydroxypropyl Hydrolyzed Hair Keratin, Cocodimonium Hydroxypropyl Hydrolyzed Keratin, Cocodimonium Hydroxypropyl Hydrolyzed Rice Protein, Cocodimonium Hydroxypropyl Hydrolyzed Soy Protein, Cocodimonium Hydroxypropyl Hydrolyzed Wheat Protein, Hydroxypropyl Arginine Lauryl / Myristyl Ether HCl, Hydroxypropyltrimonium Gelatin, Hydroxypropyltrimonium Hydrolyzed Casein, Hydroxypropyltrimonium Hydrolyzed Collagen, Hydroxypropyltrimonium Hydrolyzed Conchiolin Protein, Hydroxypropyltrimonium Hydrolyzed Keratin, Hydroxypropyltrimonium Hydrolyzed Rice Bran Protein, Hydroxypropyltrimonium Hydrolyzed Soy Protein, Hydroxypropyl Hydrolyzed Vegetable Protein, Hydroxypropyltrimonium Hydrolyzed Wheat Protein, Hydroxypropyltrimonium Hydrolyzed Wheat Protein / Siloxysilicate, Laurdimonium Hydroxypropyl Hydrolyzed Soy Protein, Laurdimonium Hydroxypropyl Hydrolyzed Wheat Protein, Laurdimonium Hydroxypropyl Hydrolyzed Wheat Protein / Siloxysilicate, Lauryldimony Hydroxypropyl Hydrolyzed Casein, Lauryldimonium Hydroxypropyl Hydrolyzed Collagen, Lauryldimonium Hydroxypropyl Hydrolyzed Keratin, Lauryldimonium Hydroxypropyl Hydrolyzed Soy Protein, Steardimonium Hydroxypropyl Hydrolyzed Casein, Steardimonium Hydroxypropyl Hydrolyzed Collagen, Steardimonium Hydroxypropyl Hydrolyzed Keratin, Steardimonium Hydroxypropyl Hydrolyzed Rice Protein, Steardimonium Hydroxypropyl Hydrolyzed Soy Protein, Steardimonium Hydroxypropyl Hydrolyzed Vegetable Protein, Steardimonium Hydroxy Propyl Hydrolyzed Wheat Protein, Steartrimonium Hydroxyethyl Hydrolyzed Collagen, Quatemium-76 Hydrolyzed Collagen, Quaternium-79 Hydrolyzed Collagen, Quaternium-79 Hydrolyzed Keratin, Quaternium-79 Hydrolyzed Milk Protein, Quaternium-79 Hydrolyzed Soy Protein, Quaternium-79 Hydrolyzed Wheat Protein.

Further care polymers which can be used according to the invention are amphoteric polymers.

As a care substance, at least one vitamin, a provitamin, a vitamin precursor and / or one of their derivatives can furthermore be used. According to the invention, such vitamins, pro-vitamins and vitamin precursors are preferred, which are usually assigned to the groups A, B ₁ C, E, F and H. Particularly preferred are vitamins belonging to the B group or to the vitamin B complex, most preferably vitamin B ₅ (pantothenic acid, panthenol and pantolactone).

As a care substance at least one plant extract can be used.

Usually these extracts are produced by extraction of the whole plant. However, in individual cases it may also be preferred to prepare the extracts exclusively from flowers and / or leaves of the plant.

With regard to the plant extracts preferred according to the invention, particular reference is made to the extracts listed in the table beginning on page 44 of the 3rd edition of the guideline for the ingredient declaration of cosmetic products, published by the Industrial Association for Personal Care and Detergent e.V. (IKW), Frankfurt.

The extracts of water lily, green tea, oak bark, nettle, witch hazel, hops, henna, chamomile, burdock root, horsetail, hawthorn, lime blossom, almond, aloe vera, spruce needle, horse chestnut, sandalwood, juniper, coconut, mango , Apricot, lime, wheat, kiwi, melon, orange, grapefruit, sage, rosemary, birch, mallow, meadowfoam, quenelle, yarrow, thyme, lemon balm, toadstool, coltsfoot, marshmallow, meristem, ginseng and ginger root.

As a care substance, a series of carboxylic acids are also suitable.

In the context of the invention, short-chain carboxylic acids may in particular be advantageous. Short-chain carboxylic acids and their derivatives in the context of the invention are understood to mean carboxylic acids which may be saturated or unsaturated and / or straight-chain or branched or cyclic and / or aromatic and / or heterocyclic and have a molecular weight of less than 750. For the purposes of the invention, preference may be given to saturated or unsaturated straight-chain or branched carboxylic acids having a chain length of from 1 to 16 C atoms in the chain, very particular preference being given to those having a chain length of from 1 to 12 C atoms in the chain.

Further suitable care substances are protein hydrolysates and / or their derivatives, wherein the use of protein hydrolysates of plant origin, eg. Soy, almond, pea, potato and wheat protein hydrolysates, is preferred. Such products are, for example, under the trademarks Gluadin ^® (Cognis), diamine ^® (Diamalt) ^® (Inolex), Hydrosoy ^® (Croda), hydro Lupine ^® (Croda), hydro Sesame ^® (Croda), Hydro tritium ^® (Croda) and Crotein ^® (Croda) available.

Although the use of the protein hydrolysates is preferred as such, amino acid mixtures otherwise obtained may be used in their place, if appropriate. Also possible is the use of derivatives of protein hydrolysates, for example in the form of their fatty acid condensation products. Such products are sold for example under the names Lamepon ^® (Cognis), Lexein ^® (Inolex), Crolastin ^® (Croda), Crosilk ^® (Croda) or Crotein ^® (Croda).

Of course, the teaching according to the invention encompasses all isomeric forms, such as eis - trans - isomers, diastereomers and chiral isomers.

According to the invention it is also possible to use a mixture of several protein hydrolysates.

Furthermore, lipids and oily substances, for example vegetable oils, liquid paraffin oils, isoparaffin oils, synthetic hydrocarbons and ester oils, enzymes and pearl extracts are suitable as a care substance.

In addition to the care substances, other auxiliaries and additives can be added.

By adding a UV filter, both the preparations themselves and the treated fibers can be protected from the harmful effects of UV radiation. It may therefore be advantageous to add at least one UV filter to the hair setting agents. The suitable UV filters are not subject to any general restrictions with regard to their structure and their physical properties. On the contrary, all UV filters which can be used in the cosmetics sector and whose absorption maximum lies in the UVA (315-400 nm), in the UVB (280-315 nm) or in the UVC (<280 nm) range are suitable. UV filters with an absorption maximum in the UVB range, in particular in the range from about 280 to about 300 nm, are particularly preferred.

The UV filters preferred according to the invention can be selected, for example, from substituted benzophenones, p-aminobenzoic acid esters, diphenylacrylic acid esters, cinnamic acid esters, salicylic acid esters, benzimidazoles and o-aminobenzoic acid esters. An example is here 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and its sodium salt (Benzophenone-4; Uvasorb ^® S 5; Uvinul ^® MS 40) mentioned. In a particular embodiment, the hair setting agent further contains one or more substantive dyes. This allows the treated keratin fiber not only to be temporarily patterned when the agent is applied, but also dyed at the same time. This may be particularly desirable if only a temporary dyeing is desired, for example, with eye-catching fashion colors, which can be removed again by simple washing from the keratinic fiber.

Furthermore, the hair setting agents may contain at least one surfactant, wherein in principle both anionic and zwitterionic, ampholytic, nonionic and cationic surfactants are suitable. In many cases, however, it has proved to be advantageous to select the surfactants from anionic, zwitterionic or nonionic surfactants.

In particular, for increasing the stability of the hair setting agents, it may be advantageous to use thickeners such as agar-agar, guar gum, alginates, xanthan gum, gum arabic, karaya gum, locust bean gum, linseed gums, dextrans, cellulose derivatives, e.g. As methyl cellulose, hydroxyalkyl cellulose and carboxymethyl cellulose, starch fractions and derivatives such as amylose, amylopectin and dextrins, clays such. Bentonite or fully synthetic hydrocolloids, e.g. Polyvinyl alcohol, admit.

The usual addition of perfume components and preservatives is possible.

Furthermore, the hair setting agents alkalizing, usually alkali or Erdalkalihydroxide, ammonia or organic amines containing. Preferred alkalizing agents are monoethanolamine, monoisopropanolamine, 2-amino-2-methyl-propanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, 2-amino-2 -methylbutanol and triethanolamine and alkali and alkaline earth metal hydroxides. In particular, monoethanolamine, triethanolamine and 2-amino-2-methyl-propanol and 2-amino-2-methyl-1, 3-propanediol are preferred in this group. The use of ω-amino acids such as ω-aminocaproic acid as an alkalizing agent is also possible.

A second object of the invention is the use of the hair setting agent according to the invention for the temporary deformation of hair.
