Description

[Technical Field]

[0001] The present invention relates to a method for treating keratin fibers such as hair, preferably for cosmetic treatment, and more preferably for conditioning. [Background technology]

[0002] In the field of hair care cosmetics, hair conditioning effects are a very important characteristic. A variety of leave-on and rinse-off hair care cosmetics have been used to condition hair.

[0003] It is known that silicone can be added to enhance the above conditioning effect. Silicone, more specifically aminosilicone, can effectively repair hair damage, and therefore, they can provide a hair conditioning effect.

[0004] On the other hand, the formulation of environmentally friendly cosmetics, designed and developed with environmental issues in mind, is becoming a major goal in addressing global challenges.

[0005] Therefore, it is essential to propose more sustainable compositions, preparation methods, and ingredients to address these environmental problems.

[0006] In this context, it is important to develop novel cosmetic compositions with a better carbon footprint, particularly by promoting the use of renewable or sustainable raw materials and / or materials with a good index of naturalness and / or materials of natural origin.

[0007] Therefore, it is preferable to limit the use of silicones in order to develop more sustainable conditioners. [Prior art documents] [Patent Documents]

[0030] The method according to the present invention may further include a step of rinsing the composition off the keratin fibers. [Modes for carrying out the invention]

[0031] As a result of diligent research, the present inventors have discovered that it is possible to provide a method for treating keratin fibers such as hair, which can bring about good cosmetic effects, preferably good suppleness and a good coated feel, as well as conditioning effects, to the keratin fibers, and which is substantially free of silicone.

[0033] The silicone (d) in the composition used in the method according to the present invention is optional. Therefore, the composition used in the method according to the present invention may or may not contain silicone (d).

[0034] If the composition used in the method according to the present invention contains (d) silicone, the amount of (d) silicone is limited such that the amount of (d) silicone in the composition is less than 1% by mass, preferably less than 0.1% by mass, and more preferably less than 0.01% by mass, relative to the total mass of the composition.

[0035] The composition used in the method according to the present invention preferably does not contain (d) silicone.

[0036] The composition used in the method according to the present invention does not contain a substantial amount of silicone, but this method can provide keratin fibers such as hair with good cosmetic effects, preferably conditioning effects such as good suppleness and a good coated feel.

[0037] For example, the method according to the present invention can provide good flexibility to keratin fibers such as dry hair. Furthermore, the method according to the present invention can also provide a sufficiently coated feel to keratin fibers such as wet hair.

[0038] The method according to the present invention is environmentally friendly because the composition used in this method does not contain a substantial amount of silicone.

[0039] The present invention will be described in detail below.

[0040] [method] The method according to the present invention is (a) at least one ester of a polyol and a fatty acid dimer, or an ester thereof (b) at least one fatty amine, and (c) Propanediol The process includes applying at least one composition containing onto keratin fibers, The composition contains less than 1% by mass, preferably less than 0.1% by mass, and more preferably less than 0.01% by mass of (d) silicone, based on the total mass of the composition.

[0041] {composition} Compositions used in the method according to the present invention (a) at least one ester of a polyol and a fatty acid dimer, or an ester thereof (b) at least one fatty amine, and (c) Propanediol Includes, The composition contains less than 1% by mass, preferably less than 0.1% by mass, and more preferably less than 0.01% by mass of (d) silicone, based on the total mass of the composition.

[0042] (Esters of polyols and fatty acid dimers, or esters thereof) The composition used in the method according to the present invention comprises (a) at least one ester of a polyol and a fatty dimer, or an ester thereof. If two or more esters of polyols and fatty dimers, or esters thereof, are used, they may be the same or different.

[0043] In the expression "ester of a polyol and a fatty dioxide dimer, or ester thereof," the term "or ester thereof" means one of the derivatives of these esters of a polyol and a fatty dioxide dimer, obtained by either the reaction of an alcohol functional group of a polyol that is not involved in the bonding of an ester type having an acid functional group of a dioxide dimer with a carboxylic acid functional group of one or more acid molecules other than a dioxide dimer, or by the reaction of an acid functional group of a dioxide dimer that is not involved in the bonding of an ester type having an alcohol functional group of a polyol with an alcohol functional group of an alcohol molecule other than a polyol.

[0044] Advantageously, an ester of a polyol and a fatty acid dimer suitable for use in the present invention, or the ester thereof, can have a viscosity of about 1,500 mPa.s or higher, as measured at about 25°C.

[0045] The viscosity of the ester of the polyol and the fatty acid dimer according to the present invention, or the viscosity of the ester, can be measured according to any method known to those skilled in the art, and, for example, according to the conventional method described below herein.

[0046] Viscosity can be measured using an Ares-type (TA-Instrument) conical / plate or parallel plate viscometer, with a time interval of approximately 1 to 1,000 s. -1 The system is operated in power sweep mode across the shear range to induce a flow tension of approximately 1,000 Pa.

[0047] The cone / plate or parallel plate may be made of a material selected from the group consisting of stainless steel, acrylic resin, or polyphenylene sulfide (PPS resin).

[0048] The diameter of the cone / plate may be 25 mm (cone angle 0.10 radians).

[0049] The measurement is performed at approximately 25°C.

[0050] Prior to any measurement, the stability of the sample is checked by a dynamic sweep period test, which allows for the determination of whether the sample itself is stable.

[0051] Shear viscosity is determined using the ETA value during the plateau region, depending on the flow.

[0052] The dynamic sweep period is determined at a frequency of 1.0 Hz over a period of 600 seconds.

[0053] Measurements during constant-speed sweeping are performed in the range of 1.0 to 1,000 seconds. -1 For example, 1.0~100s -1 It is carried out using speeds within this range.

[0054] The ester of a polyol and a fatty acid dimer suitable for use in the present invention, or the viscosity of the ester, may be in the range of about 1,500 mPa.s to about 150,000 mPa.s, or for example, about 2,000 mPa.s to about 150,000 mPa.s, or for example, about 15,000 mPa.s to about 100,000 mPa.s, or for example, about 30,000 mPa.s to about 80,000 mPa.s.

[0055] According to one embodiment, a polyol suitable for use in the present invention may be a diol dimer.

[0056] Esters of diol dimers and fatty acid dimers that can be used in the context of the present invention can be commercially available or prepared by conventional methods. They may be of plant origin and may be obtained by esterification of the fatty acid dimer with the diol dimer.

[0057] In the esterification reaction with dioxide dimers, dicarboxylic acid polyols are obtained, which may have a mass-average molecular weight determined by gel permeation chromatography (GPC) in the range of 2,000 to 25,000 g / mol, or for example, between 2,000 g / mol and 4,000 g / mol.

[0058] Dimer of acid dimer: Fatty acid dimers or dimers can conventionally be obtained by polymerization reactions, for example, by intermolecular dimerization of at least one unsaturated fatty acid.

[0059] They may contain at least two carboxylic acid groups.

[0060] As previously shown, the carboxylic acid functional group of a fatty acid dimer that does not participate in ester bonding with polyol residues can participate in other ester bonding with other alcohol functional groups of alcohol molecules other than polyols.

[0061] These alcohol molecules or residues may be monoalcohols or polyols.

[0062] Examples of alcohol residues suitable for use in the present invention include hydrocarbon compounds that contain a hydroxyl functional group and contain 4 to 40 carbon atoms, or for example 6 to 36 carbon atoms, or for example 8 to 32 carbon atoms, or for example 16 to 28 carbon atoms, or for example 18 to 24 carbon atoms.

[0063] Examples of monohydric alcohols suitable for the present invention include, but are not limited to, butanol, pentanol, propanol, hexanol, heptanol, octanol, decanol, dodecanol, hexadecanol, octadecanol, eicosadecanol, phytosterol, isostearyl alcohol, stearyl alcohol, cetyl alcohol, behenyl alcohol, etc.

[0064] The fatty diacid dimer can be derived, for example, from the dimerization of unsaturated fatty acids, such as C8-C 34 or, for example, C 12 -C 22 , particularly C 16 -C 20 and can be derived from the dimerization of unsaturated fatty acids such as, for example, C 18 .

[0065] Examples of these unsaturated fatty acids include, for example, undecenoic acid, linderic acid, myristoleic acid, palmitoleic acid, oleic acid, linoleic acid, elaidic acid, gadoleic acid, eicosapentaenoic acid, docosahexaenoic acid, erucic acid, brassidic acid, arachidonic acid, and mixtures thereof.

[0066] According to a variation of one embodiment, it may be a diacid dimer from which a diol dimer that will be esterified therefrom can also be derived. It may be in its hydrogenated form.

[0067] The hydrogenated form of the diacid dimer may be partial or total and may correspond, for example, to a saturated form that is more stable towards oxidation.

[0068] According to a variation of another embodiment, it may be a diacid dimer derived from the dimerization of linoleic acid.

[0069] According to one embodiment, the diacid dimer can be a commercial product consisting of a dicarboxylic acid containing about 36 carbon atoms. This product may also contain trimeric acids and monomeric acids in proportions depending on the purity of the product.

[0070] Products containing more than 70% dimer dioxide, and other products with dimer dioxide content adjusted to 90% or more, have been found commercially available to date.

[0071] Dimers of dilinol dioates, and dilinol dioates whose stability toward oxidation, for example, is improved by hydrogenation of the double bond remaining after the dimerization reaction, may also be commercially available.

[0072] In this invention, any commercially available dimer dioxide can be used.

[0073] In esterification reactions with diol dimers, the average degree of esterification and average molecular weight of the resulting ester can be adjusted by varying the ratio of the diol dimer to the diol dimer.

[0074] Polyols: The term "polyol" is intended to refer to any hydrocarbon compound that contains at least two hydroxyl functional groups and contains 4 to 40 carbon atoms, or, for example, 6 to 36 carbon atoms, or, for example, 8 to 32 carbon atoms, or, for example, 16 to 28 carbon atoms, and, for example, 18 to 24 carbon atoms.

[0075] The hydrocarbon chain may, where appropriate, be interrupted by the presence of at least one heteroatom, such as an oxygen atom.

[0076] The polyol or polyol ester suitable for use in the present invention may contain, for example, 2 to 12 hydroxyl functional groups, or, for example, 2 to 8 hydroxyl functional groups, or, for example, 4 to 6 hydroxyl functional groups.

[0077] Where appropriate, hydroxyl functional groups other than those already utilized in esterification with dimethyl dimers may be utilized, either entirely or partially, in other esterifications via reactions with acid molecules other than dimethyl dimers.

[0078] The polyols or esters thereof that are suitable for use in the present invention can be selected from the group consisting of linear, branched, cyclic, or polycyclic saturated or unsaturated alcohols.

[0079] Therefore, the polyol can be selected from the group consisting of, for example, diols, triols, tetraols, or pentaols, or their esters.

[0080] The polyol may be a diol or an ester thereof, selected from the group consisting of, for example, fatty alcohol dimers, monoglycerol or polyglycerol, C2-C4 monoalkylene or polyalkylene glycol, 1,4-butanediol, and pentaerythritol.

[0081] Furthermore, examples of diols suitable for use in the present invention include butanediol, pentanediol, propanediol, hexanediol, hexylene glycol, heptanediol, octanediol, nonanediol, decanediol, 1-decanediol, dodecanediol, tridecanediol, tetradecanediol, pentadecanediol, hexadecanediol, nonadecanediol, octadecanediol, cyclohexanediol, diglycerol, erythritol, pentaerythritol, xylitol, sorbitol, ethylene glycol, and xylene glycol, as well as their isomers, although these are not exhaustive.

[0082] According to one modification, an example of a diol suitable for use in the present invention is a diol dimer.

[0083] For the purposes of this invention, the term “diol dimer” is intended to mean a saturated diol derived from the hydrogenation of the corresponding diol dimer (as defined above), for example, a diol dimer of at least one unsaturated fatty acid.

[0084] With respect to industrially produced diol dimers, they also generally contain other components, such as triol trimers, monoalcohols, and ether-type compounds used as starting materials, depending on the degree of purity of the acid dimer and / or its lower alcohol ester.

[0085] Generally, products with a diol dimer content exceeding 70% can be used in the present invention. However, high-purity diol dimers, such as compounds with a diol dimer content exceeding 90%, can also be used.

[0086] Therefore, diol dimers can be produced by hydrogenation, for example, by catalytic hydrogenation of a dioxide dimer which is itself obtained by the dimerization of at least one unsaturated fatty acid.

[0087] Suitable fatty acids may be those listed above, for example, C8-C 34 things like, or for example, C 12 ~C 22 things like, or for example, C 16 ~C 20 To be more specific, C 18 It may also be something else.

[0088] According to one embodiment, the diol dimer can be derived from the hydrogenation of dilinol diacitate.

[0089] The diol dimer may be, for example, dilinoleol.

[0090] Diol dimers may generally exist in a saturated form.

[0091] Another example of a diol dimer suitable for use in the present invention is diglycerol.

[0092] This compound is a glycerol dimer formed by condensing two glycerol molecules and removing a water molecule.

[0093] The term "diglycerol" refers to any combination of isomers that can arise from such condensation, such as linear isomers, branched isomers, and, where appropriate, cyclic isomers arising from intermolecular dehydration of diglycerol molecules.

[0094] Diglycerol can be obtained by any method known to those skilled in the art, and in particular by the method described in European Patent No. 0750848.

[0095] Examples of acid molecules that can interact with one or more hydroxyl functional groups of a polyol that are not involved in ester bonding with a dioxy acid dimer include, but are not limited to, molecules derived from isostearic acid, behenic acid, phytostearic acid, stearic acid, or cetyl acid.

[0096] Esters suitable for use in the present invention can be obtained by reacting a polyol or its ester with a dimethyl dimer, such as dimer dilinoleic acid, in a molar ratio of about 1.0:0.2 to 1.

[0097] Esters suitable for use in the present invention can be obtained by reacting dimer dilinoleic acid with dilinoleol and, if appropriate, at least one additional monoalcohol selected from the group consisting of, for example, behenol, isostearol, phytosterol, stearol, and cetol, and mixtures thereof.

[0098] Therefore, the ester used in the context of the present invention can be used, for example, in the form of a mixture of various esters.

[0099] Esters suitable for use in the present invention can be obtained, for example, by reacting glycerol, isostearic acid, and dimer dilinoleic acid in a molar ratio of, for example, 1.0:0.2 to 1.0:0.5 to 0.9.

[0100] Examples of esters of dimer dilinoleic acid and polyols suitable for the present invention include those described in Japanese patent applications JP-A-2003-226609, JP-A-2004-256515, and JP-A-2005-179377.

[0101] Esters of polyols and fatty acid dimers suitable for use in the present invention, or esters thereof, can have molecular weights in the range of about 2,000 to about 25,000 g / mol, for example, about 4,000 to about 20,000 g / mol, for example, about 5,000 to about 20,000 g / mol, for example, about 7,000 to about 15,000 g / mol, and for example, about 8,000 to about 10,000 g / mol.

[0102] According to one embodiment, the ester according to the present invention may include an alternating sequence of a dioxy acid dimer residue and residues related to the polyol and, for example, the diol, wherein the polyol or diol is, for example, one of those defined above.

[0103] Therefore, in such a stereochemical arrangement, each of the two ends of the arrangement may possess units OR' and OR'' (wherein R' and R'' independently represent hydrogen atoms), or OR' and OR'' independently represent C2~C 36 For example, C8~C 24 For example, C 12 ~C 20 , and for example C 16 ~C 18 This represents a hydrocarbon monoalcohol residue.
