Description

[0001] The invention relates to hair conditioning compositions with a combability-improving effect, containing cetyl palmitate in combination with a conditioning agent selected from cationized polygalactomannans from Senna spp., in particular from Senna tora or Senna obtusifolia, and ethylenediamine-N,N'-disuccinic acid (salts) or at least one alkali metal salt or ammonium salt of this acid.

[0002] Keratinous fibers, especially hair, are an integral part of the human body and a key component of clothing and home textiles, playing a vital role in everyday life. Treatment with washing, cleaning, styling, and coloring products, as well as exposure to environmental factors such as ozone, salt and chlorinated water, IR, UV, and heat radiation (e.g., from hairdryer), leads to cumulative damage to the fibers over time, thus reducing their quality. For example, both shampooing and styling hair through coloring or perming are processes that affect the natural structure and properties of the hair. Consequently, after such treatment, the hair's wet and dry combability, hold, volume, shine, and feel may be unsatisfactory.In the case of dyed hair, especially with frequent washing, the color may still not adhere to the hair satisfactorily, leading to a gradual fading of the color.

[0003] Not least due to the significant stress placed on hair, for example by coloring or perming, as well as by shampooing and environmental pollution, the importance of hair care products with a sufficiently strong and long-lasting effect is increasing. Such products influence the natural structure and properties of the hair. For example, after such treatments, the hair's wet and dry combability, its hold and volume can be improved, or the hair can be protected against split ends.

[0004] It has therefore long been common practice to subject the hair to a special after-treatment. This usually involves treating the hair with special active ingredients, such as quaternary ammonium salts or special polymers, often in the form of a conditioner. Depending on the formulation, this treatment improves the manageability, hold, and volume of the hair and reduces split ends.

[0005] Hair conditioners contain conditioning agents and film formers that can cosmetically improve the hair's surface. For this purpose, high-molecular-weight polymers are used, for example, which adhere to the outermost layer of skin and hair, creating an externally noticeable improvement in the hair's feel. Such polymers are typically composed of petrochemically derived chain-forming monomers, such as acrylic acid, acrylamides, acrylic esters, methacrylic acid, methacrylamides, methacrylic esters, vinylpyrrolidones, vinyl acetate, vinyl alcohol, and / or styrenes. For sustainability reasons, the invention preferably avoids the use of such polymers.

[0006] To prevent, reduce, and / or at least superficially eliminate hair damage, silicone oils were often added to hair conditioners in the past. This resulted in smoother hair and improved combability. For sustainability reasons, the invention preferably avoids the use of silicones. Furthermore, silicone-containing hair conditioners can often only be satisfactorily stabilized by adding other synthetic polymers.

[0007] For sustainability reasons, efforts are also being made to replace synthetic or chemically modified active ingredients and excipients in cosmetic products with natural and biodegradable active ingredients and excipients.

[0008] Patent application EP1174112A discloses hair treatment products which, in addition to an organic acid, contain as further mandatory components an organic solvent, a cationic surfactant, and a higher alcohol, and which serve to repair pores in hair. However, the effect of these hair treatment products on the immediate cosmetic properties of the hair, in particular its combability, was still in need of improvement.

[0009] The object of the invention was to provide hair conditioning compositions with sustainably sourced conditioning agents that improve the combability, in particular the dry combability, of the hair.

[0010] Surprisingly, it was found that a hair conditioning composition containing at least one conditioning agent selected from i) at least one polygalactomannan from Senna spp., in particular from Senna tora or Senna obtusifolia, substituted with at least one cationic substituent, in a total amount of 0.05 to 2.0 wt.%, and ii) Ethylenediamine-N,N'-disuccinic acid or at least one alkali metal salt or ammonium salt of this acid in a total amount of 0.01 to 3.0 wt.%, in combination with 0.1 to 3.0 wt% cetyl palmitate, wherein all quantities refer to the weight of the hair conditioning composition, the problem according to the invention is solved.

[0011] The invention relates to hair conditioning compositions for the care of hair, but can be applied to all keratinous fibers. According to the invention, keratinous fibers include not only hair, especially human hair, but also fur, wool, feathers, and silk.

[0012] According to the invention, hair conditioning compositions are to be understood in particular as hair conditioners, hair rinses, hair treatments, leave-on conditioners and hair care sprays.

[0013] Besides rinse-out hair conditioning products, there are also leave-in formulations that remain on the hair for at least several hours after application, particularly hair masks, leave-in treatments, hair serums, or leave-in conditioners. The terms "no rinsing" and "rinse-in" mean that the product either remains in the hair for a relatively short time, for example, less than a minute if needed, or for a few minutes or an hour until it is rinsed out—usually with water—or that the product stays in the hair until the next shampoo, which can take several days. Both have certain advantages.If the formula remains on the hair for a longer period of time, the full care potential of all ingredients can be utilized, whereas a formula that is rinsed out in a short time may also contain ingredients that have a good care effect, but whose longer-lasting presence in the hair would be unpleasant.

[0014] A first object of the present invention is therefore a hair conditioning composition comprising at least one conditioning agent selected from i) at least one polygalactomannan from Senna spp., in particular from Senna tora or Senna obtusifolia, substituted with at least one cationic substituent, in a total amount of 0.05 to 2.0 wt.%, and ii) Ethylenediamine-N,N'-disuccinic acid or at least one alkali metal salt or ammonium salt of this acid in a total amount of 0.01 to 3.0 wt.%, in combination with 0.1 to 3.0 wt% cetyl palmitate, where all quantities refer to the weight of the hair conditioning composition.

[0015] A second object of the present invention is a method for improving the combability of keratin fibers, in particular for improving the dry combability of keratin fibers, in which a conditioning agent selected from i) at least one polygalactomannan from Senna spp., in particular from Senna tora or Senna obtusifolia, substituted with at least one cationic substituent, and ii) Ethylenediamine-N,N'-disuccinic acid or at least one alkali metal salt or ammonium salt of this acid, applied to the keratin fibers and optionally rinsed out of the keratin fibers after an exposure time of one second to four hours, wherein the at least one conditioning agent i) or ii) is preferably contained in a hair conditioning composition according to the invention or preferably according to the invention.

[0016] A third aspect of the present invention is the use of at least one conditioning agent selected from i) at least one polygalactomannan from Senna spp., in particular from Senna tora or Senna obtusifolia, substituted with at least one cationic substituent, and ii) Ethylenediamine-N,N'-disuccinic acid or at least one alkali metal salt or ammonium salt of this acid, for improving the combability of keratin fibers, in particular for improving the dry combability of keratin fibers, wherein the at least one conditioning agent i) or ii) is preferably contained in a hair conditioning composition according to the invention or preferred according to the invention.

[0017] The first subject matter of the invention, summarized above, will now be described in more detail.

[0018] The following statements regarding the hair conditioning compositions according to the invention and those preferred according to the invention apply mutatis mutandis to the aforementioned use according to the invention.

[0019] The following statements regarding the hair conditioning compositions according to the invention and those preferred according to the invention apply mutatis mutandis to the aforementioned method according to the invention.

[0020] Unless otherwise stated, all quantities given in % are wt.% and refer to the weight of the hair conditioning composition.

[0021] In a first embodiment of the first object of the present invention, the hair conditioning compositions according to the invention are characterized in that they contain as a conditioning agent at least one polygalactomannan from Senna spp., in particular from Senna tora or Senna obtusifolia, which is substituted with at least one cationic substituent, in a total amount of 0.05 to 2.0 wt.%, preferably 0.1 to 1.0 wt.%, particularly preferably 0.3 to 0.5 wt.%, in each case based on the weight of the hair conditioning composition.

[0022] Surprisingly, it was found that the at least one compound selected from polygalactomannans from Senna spp., in particular from Senna tora or Senna obtusifolia, which are substituted with at least one cationic substituent, smooths the surface of damaged keratin fibers in a hair conditioning composition according to the invention, which is noticeable, among other things, by an objectively measured improvement in combability, in particular dry combability, as described in the experimental part of this application.

[0023] The plant genus Senna comprises a large portion of the species previously classified as Cassia (Senna). Senna tora was previously often referred to as Cassia tora. Senna obtusifolia was previously often referred to as Cassia obtusifolia. The plant genus Senna belongs to the subfamily Caesalpinioideae within the legume family (Fabaceae). Polygalactomannans are polysaccharides found in the endosperm of legume seeds. A polygalactomannan consists of a chain of 1->4-linked β-D-mannopyranosyl units with recurring 1->6-linked side chains of α-D-galactosyl groups branching off from carbon atom number 6 of a mannopyranose residue. The galactomannan polymers of the different Leguminosae species differ in the frequency of occurrence of the galactosyl side chains branching off from the polymannopyranose backbone.The average ratio of D-mannosyl to D-galactosyl units in polygalactomannan is approximately 2:1 for guar gum, approximately 3:1 for tara gum, and approximately 4:1 for locust bean gum. Another important source of polygalactomannan is Senna tora (Cassia tora) and Senna obtusifolia (Cassia obtusifolia). The average ratio of D-mannosyl to D-galactosyl in senna polygalactomannan (Cassia polygalactomannan) is at least 5:1.

[0024] The cationization of the senna polygalactomannan used according to the invention is carried out by replacing some of the hydrogen groups of the hydroxy groups in the mannosyl and galactosyl residues with a group represented by the formula -AR 23 , where A represents a substituted or unsubstituted alkylene group with 1 to 6 carbon atoms and R 23 for a group -N(R 24 )3 + X - states in which R 24independently of each other stands for substituted and unsubstituted C1 to C24 alkyl groups, substituted and unsubstituted benzyl groups and substituted and unsubstituted phenyl groups and X - for any suitable anion that balances the charge of the onium cation.

[0025] In a preferred embodiment according to the invention, A represents a substituted alkylene group with 1 to 6 carbon atoms, which is substituted with one or more substituents selected from C1-C3 alkyl, C1-C3 haloalkyl, hydroxyl, and halogen. In a further preferred embodiment according to the invention, A represents a substituted alkylene group with 2 to 3 carbon atoms, which is substituted with one or more substituents selected from C1-C3 alkyl, in particular methyl, and hydroxyl. In a further preferred embodiment according to the invention, A represents a substituted propylene group, which is substituted with one or more hydroxyl groups. Senna polygalactomannans (cassia polygalactomannans) cationized with 2-hydroxy-3-(trimethylammonium)propyl groups are particularly preferred according to the invention.

In a further preferred embodiment according to the invention, the senna polygalactomannan (cassia polygalactomannan) with 2-hydroxy-3-(trimethylammonium)propyl groups is cationized with chloride as a counterion, has a cationic charge density in the range of 1.4 - 3.5 meq / g, preferably 1.5 - 3.2, particularly preferably 1.6 - 3.0 meq / g and a molecular weight in the range of 200000 - 3000000, preferably 300000 - 2000000, particularly preferably 400000 - 1000000 Daltons.In a further preferred embodiment according to the invention, at least one senna polygalactomannan (cassia polygalactomannan) cationized with 2-hydroxy-3-(trimethylammonium)propyl groups, having a cationic charge density in the range of 1.4 - 3.5 meq / g, preferably 1.5 - 3.2, particularly preferably 1.6 - 3.0 meq / g and a molecular weight in the range of 200000 - 3000000, preferably 300000 - 2000000, particularly preferably 400000 - 1000000 Daltons, is included in a total amount of 0.05 to 2.0 wt.%, particularly preferably 0.1 to 1.0 wt.%, and most preferably 0.3 to 0.5 wt.%, in each case based on the weight of the hair conditioning composition.

[0029] In a second embodiment of the first subject matter of the present invention, the hair conditioning compositions according to the invention are characterized in that they contain ethylenediamine-N,N'-disuccinic acid or at least one alkali metal salt or ammonium salt of this acid as the conditioning agent in a total amount of 0.01 to 3.0% by weight, based on the weight of the hair conditioning composition according to the invention. Further hair conditioning compositions preferred according to the invention are characterized in that the at least one salt of ethylenediamine-N,N'-disuccinic acid is selected from the sodium salts, potassium salts, and ammonium salts, as well as from mixtures of these salts.Particularly preferred hair conditioning compositions according to the invention are characterized in that the conditioning active ingredient is selected from the monosodium salt, the disodium salt, the trisodium salt and the tetrasodium salt of ethylenediamine-N,N'-disuccinic acid as well as from mixtures thereof, wherein the trisodium salt and the tetrasodium salt of ethylenediamine-N,N'-disuccinic acid are preferred and the trisodium salt of ethylenediamine-N,N'-disuccinic acid is particularly preferred.

[0030] Further hair conditioning compositions particularly preferred according to the invention are characterized in that the at least one component a)ii), which is selected from ethylenediamine-N,N'-disuccinic acid or an alkali metal or ammonium salt of this acid, is contained in a total amount of 0.02 to 2.0 wt.%, preferably 0.03 to 1.0 wt.%, particularly preferably 0.04 to 0.5 wt.%, in each case based on the weight of the hair conditioning composition according to the invention.

[0032] Further hair conditioning compositions particularly preferred according to the invention are characterized in that component a) ii) contains the trisodium salt of ethylenediamine-N,N'-disuccinic acid in an amount of 0.02 to 2.0 wt.%, preferably 0.03 to 1.0 wt.%, particularly preferably 0.04 to 0.5 wt.%, in each case based on the weight of the hair conditioning composition.

[0033] Further hair conditioning compositions that are particularly preferred according to the invention are characterized in that cetyl palmitate is contained in an amount of 0.2 to 2.0 wt.%, preferably 0.3 to 1.0 wt.%, particularly preferably 0.4 to 0.7 wt.%, in each case based on the weight of the hair conditioning composition.

[0034] In a preferred embodiment, the hair conditioning compositions according to the invention are characterized in that they contain at least one non-ethoxylated amidoalkylamine of formula (II): wherein - R1 a C 11 - C 25 - alkyl group, which can be saturated or unsaturated and linear or branched, - the index n is a number from 2 to 5, preferably 3 or 4, particularly preferably 3, - the remains R 2 and R 3 independently of each other, representing a methyl, ethyl or n-propyl group, particularly preferably R 2 and R 3 each represents a methyl group.

[0035] Preferably, the at least one non-ethoxylated amidoalkylamine of formula (II) is contained in a total amount of 0.01 to 5.0 wt.%, preferably 0.1 to 4.0 wt.%, more preferably 0.5 to 3.0 wt.%, and most preferably 0.8 to 1.5 wt.%, based on the weight of the hair conditioning composition.

[0036] It was surprisingly found that the at least one compound selected from amidoalkylamines according to the preceding formula (II) in a hair conditioning composition according to the invention smooths the surface of damaged keratin fibers, which is noticeable, among other things, by an objectively measured improvement in combability, in particular dry combability, as described in the experimental part of this application. Amidoalkylamines are usually prepared by amidation of natural or synthetic C8-C24 fatty acids or C8-C24 fatty acid fractions with di-(C1-C3)alkylaminoamines. Amidoalkylamines preferred according to the invention have the following formula (II): wherein - R 1 a C 11 - C 25 - alkyl group, which can be saturated or unsaturated and linear or branched, - the index n is the number 3 or 4, preferably 3, - the remains R 2 and R 3independently of each other, representing a methyl, ethyl or n-propyl group, particularly preferably R 2 and R 3 each represents a methyl group.

[0037] Particularly preferred residues R 1 are selected from n-undecyl, n-tridecyl, n-pentadecyl, n-heptadecyl, n-nonadecyl and n-heneicosanyl, as well as from mixtures thereof. Particularly preferred amidoalkylamines of formula (II) are C 12 - C 22-Amido-n-propyldimethylamines. The amidoalkylamines according to formula (II) are so-called pseudoquats. All organic residues are directly bonded to the nitrogen atom. In the acidic pH range, these become cationized, i.e., the nitrogen atom is protonated, with the anionic counterions of the protonated amidoalkylamines being the acid anions contained in the respective composition. In the preferably acidic environment of the hair conditioning compositions according to the invention, these amidoalkylamines exist in a cationic form. Particularly preferred amidoalkylamines of the above formula (II) are selected from stearamidopropyldimethylamine and behenamidopropyldimethylamine.

[0040] Hair conditioning compositions preferred according to the invention typically have a pH value in the acidic to slightly alkaline range, which, on the one hand, smooths the outer cuticle layer of the keratin fibers and, on the other hand, also supports the improvement of the internal fiber structure of the keratin fibers and the repair of structural damage to the fibers. Hair conditioning compositions according to the invention therefore particularly preferably have a pH value in the range of 3.0 to 7.8, more preferably 3.5 to 6.5, more preferably 4.0 to 6.0, further more preferably 4.5 to 5.5, and most preferably 4.9 to 5.2, in each case measured at 20°C.

[0041] As a further optional ingredient, the hair conditioning compositions according to the invention contain - based on their weight - at least one cationic surfactant in a total amount of 0.01 - 8 wt.%, preferably 0.1 to 6 wt.%, particularly preferably 0.5 - 5 wt.%, extraordinarily preferably 1 - 4 wt.%, further extraordinarily preferably 1.1 - 3 wt.%, wherein the cationic surfactant is selected from quaternary ammonium compounds with at least one C8-C24 alkyl group, quaternary imidazolines, esterquats with at least one C8-C24 acyl group, and mixtures of the aforementioned substances.

[0042] The terms "surfactants" and "emulsifiers" refer to surface-active substances that form adsorption layers on surfaces and interfaces or can aggregate in bulk phases to form micelle colloids or lyotropic mesophases. Basic properties of surfactants and emulsifiers are oriented absorption at interfaces, aggregation into micelles, and the formation of lyotropic phases. A distinction is made between anionic surfactants, consisting of a hydrophobic residue and a negatively charged hydrophilic head group; amphoteric surfactants, which carry both a negative and a compensating positive charge; cationic surfactants, which have a hydrophobic residue and a positively charged hydrophilic group; and nonionic surfactants, which have no charges but exhibit strong dipole moments and are highly hydrated in aqueous solution.

[0043] In principle, all cationic surfactants suitable for use on the human body according to the preceding definition are suitable as cationic surfactants in hair conditioning compositions according to the invention, wherein the cationic surfactant is selected from quaternary ammonium compounds with at least one C8-C24 alkyl group, quaternary imidazolines, esterquats with at least one C8-C24 acyl group, and mixtures of the aforementioned substances. These are characterized by at least one water-soluble cationic group, such as a quaternary ammonium group, or by at least one water-soluble, cationizable group, such as an amine group, and furthermore by at least one lipophilic alkyl group with approximately 6 to 30 carbon atoms, or also by at least one imidazole group or at least one imidazolylalkyl group.

[0045] Particularly preferred quaternary ammonium compounds with at least one C8-C24 alkyl group are the halides, especially chlorides, and the alkyl sulfates, such as methosulfates or ethosulfates, of C8-C24 alkyltrimethylammonium, C8-C24 dialkyldimethylammonium, and C8-C24 trialkylmethylammonium. The alkyl chains of the surfactants mentioned above have 8 to 24 carbon atoms, preferably 12 to 22 carbon atoms, and particularly preferably 16 to 18 carbon atoms. Exceptionally preferred cationic surfactants of this type are selected from cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, distearyldimethylammonium chloride, dilauryldimethylammonium chloride, and lauryldimethylbenzylammonium chloride, as well as mixtures thereof, with cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, and behenyltrimethylammonium chloride being particularly preferred.

[0046] Particularly preferred quaternary imidazoline compounds are selected from those having the following formula (III): wherein - R 1 and R 2 independently of one another, represent a saturated or unsaturated C7-C27 alkyl group, preferably a saturated or unsaturated C11-C21 alkyl group, particularly preferably a saturated or unsaturated C15-C17 alkyl group, - X - is a physiologically compatible anion.

[0047] A particularly preferred compound of this class according to the invention is Quaternium-87 (CAS number 92201-88-2), which is available, for example, from Evonik as Varisoft W 575 PG. Quaternary imidazolines or imidazolium compounds that are particularly preferred according to the invention are selected from compounds known under the INCI names Quaternium-27, Quaternium-83, Quaternium-87, and Quaternium-91. A compound preferred according to the invention is Quaternium-87.

[0048] Esterquats are cationic surfactants that contain at least one ester group, at least one quaternary ammonium group as a structural element, and at least one C8-C24 alkyl group or one C8-C24 acyl group. The esterquat can have the following formula: where - R 19 and R 20 independently represent a C1-C6 alkyl group or a C2-C6 hydroxyalkyl group, - R 21 , R 22 independently of each other a C7-C27 alkyl group, preferably a C 10 -C 22 -alkyl group, represent and - X - is a physiologically compatible anion.

[0049] Preferred esterquats are quaternary ester salts of fatty acids with triethanolamine, quaternary ester salts of fatty acids with diethanolalkylamines, and quaternary ester salts of fatty acids with 1,2-dihydroxypropyldialkylamines. Such products are marketed, for example, under the trademarks Stepantex®, Dehyquart®, and Armocare®. N,N-Bis(2-palmitoyloxyethyl)dimethylammonium chloride, distearoylethyldimonium methosulfate, and distearoylethylhydroxyethylmonium methosulfate are preferred examples of such esterquats, particularly distearoylethylhydroxyethylmonium methosulfate. Another preferred esterquat is behenoyl PG-trimonium chloride.

[0050] In accordance with the present invention, hair conditioning compositions are preferred that are free of peroxide compounds other than atmospheric oxygen. Peroxide compounds commonly used as oxidizing agents in hair cosmetics include hydrogen peroxide, persulfates, perbromates, percarbonates, perborates, and percarbamides. The oxygen contained in ambient air does not constitute an oxidizing agent in the context of the invention.

[0051] Further hair conditioning compositions preferred according to the invention are characterized in that they contain at least one non-ionic surfactant. These are particularly mild and thus support the conditioning effect of the invention. Non-ionic surfactants preferably contain as a hydrophilic group a polyol group, one or more polyalkylene glycol ether groups, in particular one or more polyethylene glycol ether groups, or a combination of polyol and polyglycol ether groups. Preferred non-ionic surfactants are, for example... - Addition products of 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide to linear and branched fatty alcohols with 8 to 30 carbon atoms, to fatty acids with 8 to 30 carbon atoms and to alkylphenols with 8 to 15 carbon atoms in the alkyl group, - End-group sealed addition products of 2 to 50 mol ethylene oxide and / or 0 to 5 mol propylene oxide to linear and branched fatty alcohols with 8 to 30 carbon atoms, to fatty acids with 8 to 30 carbon atoms and to alkylphenols with 8 to 15 carbon atoms in the alkyl group, with a methyl or C2-C6 alkyl group, - C 12 -C 30 Fatty acid mono- and diesters of adsorption products of 1 to 30 mol of ethylene oxide to glycerol, - Deposition products of 5 to 60 mol of ethylene oxide on castor oil and hydrogenated castor oil, - alkoxylated, especially ethoxylated, triglycerides, - alkoxylated fatty acid alkyl esters of formula (XIV) R 1 CO-(OCH2CHR 2 ) w OR 3 (XIV), in the R 1 CO for a linear or branched, saturated and / or unsaturated acyl group with 6 to 22 carbon atoms, R 2 for hydrogen or methyl, R 3for linear or branched alkyl groups with 1 to 4 carbon atoms and w stands for numbers from 1 to 20, - Amine oxides, - Hydroxy mixed ethers, as described, for example, in DE-OS 19738866, - Sorbitan fatty acid esters and adsorption products of ethylene oxide to sorbitan fatty acid esters, such as the polysorbates, - Sugar fatty acid esters and adsorption products of ethylene oxide to sugar fatty acid esters, - Addition products of ethylene oxide to fatty acid alkanolamides and fatty amines, - Sugar surfactants of the type of alkyl and alkenyl oligoglycosides according to formula (XV), R 4 O-[G] p (XV) in the R 4G represents an alkyl or alkenyl group with 4 to 22 carbon atoms, G represents a sugar group with 5 or 6 carbon atoms, and p represents numbers from 1 to 10. They can be obtained by the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably from glucose. The preferred alkyl and / or alkenyl oligoglycosides are therefore alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (XV) indicates the degree of oligomerization (DP), i.e., the distribution of mono- and oligoglycosides, and represents a number between 1 and 10.
