Description

Technical Field

[0001] The present invention relates to compositions for treating (e.g., conditioning) keratin fibers (e.g., hair). Background Technology

[0002] In the field of hair cosmetics, hair conditioning effects are a very important property. A wide variety of leave-in and rinse-out hair care products are available for conditioning hair.

[0003] To enhance these conditioning effects, it has been proposed to add hydrophobic ingredients, such as silicone. Silicones (especially amino silicones) are effective at repairing hair damage, and therefore, they provide hair conditioning effects.

[0033] The best way to implement an invention

[0034] After diligent research, the inventors have discovered that it is possible to provide compositions that offer improved conditioning effects for keratin fibers (such as hair), with a particularly less heavy feel and less stickiness.

[0035] Therefore, the present invention mainly relates to compositions for treating keratin fibers, comprising:

[0036] (a) an oligomer of at least one hydroxylated fatty acid triglyceride and saturated diacid; and

[0037] (b) at least one amino silicone,

[0038] in

[0039] (b) Aminosilicone has a degree of polymerization of less than 2,000.

[0040] This invention can provide improved conditioning effects for keratin fibers (such as hair), especially with less heavy feel and less stickiness.

[0041] The compositions according to the invention also provide good manageability for keratin fibers.

[0042] Therefore, the present invention provides a cosmetic treatment for keratin fibers, preferably for conditioning keratin fibers, and more preferably for providing keratin fibers with a light touch and smoothness.

[0043] The compositions according to the invention can also provide a uniform coating on keratin fibers without providing an excessively thick / greasy feel.

[0044] "Keratin fiber" herein refers to a fiber comprising at least one keratin substance. Preferably, at least a portion of the surface of the keratin fiber is formed of keratin substance. Examples of keratin fibers include hair, eyebrows, eyelashes, etc. Preferably, the present invention is used for treating hair.

[0045] The present invention will now be described in detail.

[0046] [Composition]

[0047] One aspect of the present invention relates to a composition for treating keratin fibers (e.g., hair), comprising:

[0048] (a) an oligomer of at least one hydroxylated fatty acid triglyceride and saturated diacid; and

[0049] (b) at least one amino silicone,

[0050] in

[0051] (b) Aminosilicone has a degree of polymerization of less than 2,000.

[0052] (Oligomers of triglycerides of hydroxylated fatty acids and saturated diacids)

[0053] The compositions according to the invention comprise (a) an oligomer of at least one hydroxylated fatty acid triglyceride and a saturated diacid. If two or more oligomers of hydroxylated fatty acid triglycerides and saturated diacids are used, they may be the same or different.

[0054] The term "oligomer" here refers to a polymer in which a relatively small number of monomers are bonded. Preferably, the number of monomers in the oligomer is 100 or less, more preferably 50 or less, and even more preferably 20 or less.

[0055] Oligomers of (a)-hydroxylated fatty acid triglycerides and saturated diacids can be obtained by reacting triglycerides of hydroxylated fatty acids (e.g., hydrogenated castor oil) with saturated diacids. This reaction can be esterification. Therefore, oligomers of (a)-hydroxylated fatty acid triglycerides and saturated diacids can be oligoesters of hydroxylated fatty acids and saturated diacids.

[0056] According to the present invention, a diacid is said to be saturated when the hydrocarbon-based chain constituting the diacid does not contain unsaturated groups (i.e., carbon-carbon double bonds). The term "diacid" here refers to a hydrocarbon-based compound containing two -COOH carboxyl functional groups. A diacid can be a single diacid or a mixture of several different diacids.

[0057] Similarly, in the context of this invention, an oligomer can be a mixture of several different oligomers.

[0222] Preferably, (c) the silicone is selected from silicone oil.

[0223] Here, "silicone oil" refers to silicone compounds or substances that are liquid or paste-like at atmospheric pressure (760 mmHg) and room temperature (25°C). Silicone oils can be used alone or in combination with those commonly used in cosmetics.

[0224] Silicones or organopolysiloxanes are defined, for example, by Walter NOLL in "Chemistry and Technology of Silicones" (1968), Academic Press. They can be volatile or non-volatile.

[0225] Therefore, silicone oils can be selected from volatile silicones, non-volatile silicones, and mixtures thereof.

[0226] Therefore, silicone oil may contain at least one volatile silicone oil or at least one non-volatile silicone oil, or both at least one volatile silicone oil and at least one non-volatile silicone oil.

[0227] The volatile or non-volatile silicone may be selected from linear, branched or cyclic silicones, and may be modified with at least one organic functional moiety or group.

[0228] For example, the silicone oil may be selected from polydialkylsiloxanes, such as polydimethylsiloxane (PDMS); polyalkylarylsiloxanes, such as phenyl polytrimethylsiloxane, polydiarylsiloxane; and organically modified polysiloxanes containing at least one organic functional part or group selected from: polyoxyethylene part or group, alkoxy or alkoxyalkyl part or group, hydroxyl or hydroxylated part or group, acyloxy or acyloxyalkyl part or group, carboxylic acid or carboxylic acid ester part or group, acrylic part or group, and oxazoline part.

[0229] If the silicone oil is volatile, it can be selected from those with a boiling point range of 60℃-260℃, for example:

[0230] (i) Cyclic silicones, such as polydialkylsiloxanes containing 3-7 (e.g., 4-5) silicon atoms. Non-limiting examples of such siloxanes include, for example, those produced by UNION CARBIDE under the trade name VOLATILE. 7207 was sold and sold by RHODIA under the brand name Octamethylcyclotetrasiloxane sold by 70045V2; produced by Union Carbide under the trade name VOLATILE 7158 sold, and by RHODIA under the product name Decamethylcyclopentasiloxane, sold by SHIN ETSU under the trade name KF-995, and mixtures thereof. Cyclic dialkylsiloxanes, such as those sold by DOW CORNING under the reference names DC 244, DC 245, DC 344, DC 345, and DC 246, may also be used. Cyclic copolymers of the dimethylsiloxane / methylalkylsiloxane type, such as SILICONE, sold by UNION CARBIDE, may also be used. FZ 3109 has the following formula:

[0231]

[0232] in;

[0233] D″ is and

[0234] D′ is

[0235] Combinations of cyclic silicones (e.g., polydialkylsiloxanes) with silicon-derived organic compounds can also be used, such as mixtures of octamethylcyclotetrasiloxane and tetra(trimethylsilyl)pentaerythritol (50 / 50), and mixtures of octamethylcyclotetrasiloxane and oxy-1,1′-bis(2,2,2′,2′,3,3′-hexa(trimethylsiloxy))neopentane; and

Silicones belonging to this category are also described, for example, in Cosmetics and Toiletries, Vol. 91, January 1976, pp. 27-32-TODD & BYERS "Volatile Silicone Fluids for Cosmetics".

[0237] If the silicone oil is volatile, it can be selected from cyclic silicones.

[0238] On the other hand, silicone oils can be selected from non-volatile silicones, such as polydialkylsiloxanes, polyalkylarylsiloxanes, polydiarylsiloxanes, and organically modified polysiloxanes as explained above.

[0239] (c) The molecular weight of the silicone (preferably a polydimethylsiloxane containing a trimethylsilyl end group) has the following weight-average molecular weight (Mw): 300,000 or greater, preferably 350,000 or greater, more preferably 400,000 or greater, and preferably 3,000,000 or less, more preferably 2,000,000 or less, and even more preferably 1,000,000 or less.

[0240] According to one embodiment, (c) the silicone (preferably silicone oil) may be selected from a non-volatile polydialkylsiloxane, such as a polydimethylsiloxane containing a trimethylsilyl end group known under the trade name dimethicones.

[0241] According to the present invention, the preferred silicone (c) can be a polydimethylsiloxane containing a trimethylsilyl end group, for example having a value greater than 1,000,000 cSt (mm) at 25°C. 2Oils with a viscosity of ( / s), even more preferably greater than 2,000,000 cSt, and even more particularly greater than 5,000,000 cSt, still more preferably greater than 10,000,000 cSt, and preferably less than 50,000,000 cSt, still more preferably less than 30,000,000 cSt, and even still more preferably less than 15,000,000 cSt.

[0261] If the silicone oil is non-volatile, it can be selected from polydimethylsiloxane and organically modified polydimethylsiloxane.

[0262] Preferably, the silicone oil is selected from volatile or non-volatile silicone oils, such as volatile or non-volatile polydimethylsiloxanes (PDMS) containing linear or cyclic silicone chains, which are liquid or paste at ambient temperature, especially cyclic polydimethylsiloxanes (cyclomethicone oils), such as decamethylcyclopentasiloxane and dodecylcyclohexasiloxane; polydimethylsiloxanes containing alkyl, alkoxy, or phenyl groups as side groups of the silicone chain and / or at the ends of the silicone chain, said groups having 2-24 carbon atoms; phenyl silicones, such as phenyl polytrimethylsiloxane, phenyl polydimethylsiloxane, phenyltrimethylsiloxydiphenylsiloxane, diphenyl polydimethylsiloxane, diphenylmethyldiphenyltrisiloxane, 2-phenylethyltrimethylsiloxysilicate, and polymethylphenylsiloxane; and organically modified silicones, such as polydimethylsiloxane alcohol.

[0269] (Ester of a polyol and a fatty diacid dimer or its ester)

[0270] The compositions according to the invention may further comprise (d) at least one ester of a polyol and a fatty diacid dimer, or an ester thereof. If two or more esters of a polyol and a fatty diacid dimer, or esters thereof, are used, they may be the same or different.

[0271] In the expression “ester of a polyol and a fatty diacid dimer, or an ester thereof”, the term “or an ester thereof” means one of these esters and derivatives of a polyol and a fatty diacid dimer obtained by either: a reaction of the alcohol functional group of the polyol (which does not participate in the ester bond with the acid functional group of the diacid dimer) with one or more carboxyl functional groups of an acid molecule other than the diacid dimer, or a reaction of the acid functional group of the diacid dimer (which does not participate in the ester bond with the alcohol functional group of the polyol) with the alcohol functional group of an alcohol molecule other than the polyol.

[0272] Advantageously, esters of polyols and fatty diacid dimers, or esters thereof, suitable for use in this invention, may have a viscosity greater than or equal to about 1,500 mPa·s when measured at about 25°C.

[0273] The viscosity of the polyol and fatty acid dimer, or the ester thereof, according to the invention can be measured using any method known to those skilled in the art, and for example, using the conventional methods described below.

[0274] Viscosity can be measured using an Ares-type cone / plate or parallel plate viscometer (TA-Instrument), which has a viscosity range of approximately 1-1,000 s. -1 It operates in a dynamic sweep mode within the shear range to induce a flow tension of approximately 1,000 Pa.

[0275] The cone / plate or parallel plate may be made of a material selected from stainless steel, acrylic resin or polyphenylene sulfide (PPS resin).

[0276] The diameter of the cone / plate can be 25mm (cone angle 0.10 radians).

[0277] The measurement was performed at approximately 25°C.

[0278] Before any measurement, the stability of the sample is checked using a dynamic scan cycle test, which makes it possible to determine whether the sample itself is stable.

[0279] The shear viscosity is determined based on the ETA value in the flow platform region.

[0280] The dynamic scan cycle is determined at a frequency of 1.0 Hz within a 600-second time period.

[0281] With a range of 1.0s -1 Up to 1,000s -1 And for example, 1.0s -1 up to 100s -1 Measurements were performed at a constant scan rate.

[0282] The viscosity range of the polyol and fatty diacid dimer ester, or the ester thereof, suitable for use in this invention, may be 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.

[0283] According to one embodiment, the polyol suitable for use in this invention may be a diol dimer.

[0284] The esters of diol dimers and fatty diacid dimers that can be used in the context of this invention are commercially available or can be prepared in a conventional manner. They can be derived from plants and can be obtained by esterification of diacid dimers and diol dimers.

[0285] In the esterification reaction with the diacid dimer, a polyol dicarboxylic acid ester is obtained, and its weight-average molecular weight range can be 2,000-25,000 g / mol or, for example, between 2,000 g / mol and 4,000 g / mol, as determined by gel permeation chromatography (GPC).

[0286] Dicarboxylic acid dimer:

[0287] Fatty acid dimers or diacid dimers can be conventionally obtained through polymerization reactions, such as through intermolecular dimerization of at least one unsaturated fatty acid.

[0288] They may contain at least two carboxylic acid groups.

[0289] As mentioned above, the carboxyl functional group of fatty diacid dimers that does not participate in ester bonds with polyol residues can participate in other ester bonds with other alcohol functional groups of alcohol molecules other than polyols.

[0290] These alcohol molecules or residues can be monohydric or polyhydric alcohols.

[0291] As examples of alcohol residues suitable for use in this invention, references may be made to hydrocarbon-based compounds that contain a hydroxyl functional group and have 4-40 carbon atoms, or for example 6-36 carbon atoms, or for example 8-32 carbon atoms, or for example 16-28 carbon atoms, or for example 18-24 carbon atoms.

[0292] Examples of monohydric alcohols applicable to this invention include, in a non-limiting manner, butanol, pentanol, propanol, hexanol, heptanol, octanol, decanol, dodecanol, hexadecanol, octadecanol, eicosadecanol, phytosterol, isostearyl alcohol, stearyl alcohol, cetyl alcohol, betaine alcohol, etc.

[0293] Fatty acid dimers can be obtained from, for example, unsaturated fatty acids (e.g., C8-C). 34 Unsaturated fatty acids or, for example, C 12 -C 22 Unsaturated fatty acids, especially C 16 -C 20 Unsaturated fatty acids, such as C 18 Dimerization of unsaturated fatty acids.

[0294] Examples of these unsaturated fatty acids include, for example, undecenoic acid, linoleic acid, myristone acid, palmitoleic acid, oleic acid, linoleic acid, transoleic acid, gadolenoic acid, eicosapentaenoic acid, docosahexaenoic acid, erucic acid, brassinolic acid, and arachidonic acid, and mixtures thereof.

[0295] According to one embodiment variation, it can be a diacid dimer from which the diol dimer to be esterified is obtained. It can be its hydrogenated form.

[0296] The hydrogenated form of the diacid dimer can be partial or complete (hydrogenated form) and can correspond to, for example, the saturated form which is more stable for oxidation.

[0297] According to another variant of the implementation, it can be a dicarboxylic acid dimer derived from the dimer of linoleic acid.

[0298] According to one embodiment, the diacid dimer can be a commercial product composed of dicarboxylic acids containing about 36 carbon atoms. The product may also contain trimer acid and monomeric acid in proportions depending on the purity of the product.

[0299] Products with a dicarboxylic acid dimer content of more than 70% and other products with a dicarboxylic acid dimer content adjusted to 90% or more are available through regular commercial purchases.

[0300] Dicarboxylic acid dimers are also commercially available, and, for example, dilinoleic diacid, the stability against oxidation has been improved by hydrogenating the double bonds retained after the dimerization reaction.

[0301] In this invention, any currently commercially available diacid dimer can be used.

[0302] In the esterification reaction with diacid dimers, the average degree of esterification and average molecular weight of the obtained ester can be adjusted by changing the ratio of diol dimer to diacid dimer.

[0303] Polyols:

[0304] The term "polyol" is intended to mean any hydrocarbon-based compound that contains at least two hydroxyl functional groups and has 4-40 carbon atoms, or for example 6-36 carbon atoms, or for example 8-32 carbon atoms, or for example 16-28 carbon atoms, and for example 18-24 carbon atoms.

[0305] Under appropriate circumstances, a hydrocarbon-based chain can be interrupted by the presence of at least one heteroatom (and, for example, an oxygen atom).

[0306] The polyols or polyol esters suitable for use in this invention may contain, for example, 2-12 hydroxyl functional groups, or, for example, 2-8 hydroxyl functional groups, or, for example, 4-6 hydroxyl functional groups.

[0307] In appropriate circumstances, hydroxyl functional groups other than those already used in the ester bonds of the diacid dimer can be used, either wholly or partially, in other ester bonds through reactions with acid molecules other than diacid dimers.

[0308] The polyols or their esters suitable for use in this invention may be selected from linear, branched, cyclic or polycyclic, saturated or unsaturated alcohols.

[0309] Therefore, polyols can be selected from, for example, diols, triols, tetraols or pentaols, or their esters.

[0310] The polyol may be selected from, for example, the following diols or their esters: fatty alcohol dimers, monoglycerides or polyglycerides, C2-C4 monoalkylene glycols or polyalkylene glycols, 1,4-butanediol and pentaerythritol.

[0311] Examples of diols also suitable for use in this invention include, in a non-exhaustive manner, butanediol, pentanediol, propylene glycol, hexanediol, hexylene glycol, heptanediol, octanediol, nonanediol, decanediol, 1-decanediol, dodecanediol, tridecanediol, tetradecanediol, pentadecanediol, hexadecanediol, nonadecanediol, octadecanediol, cyclohexanediol, diglycerides, erythritol, pentaerythritol, xylitol, sorbitol, ethylene glycol, and xylene glycol, and their isomers.

[0312] According to one variant, as an example of a diol suitable for use in this invention, diol dimers may be mentioned.

[0313] For the purposes of this invention, the term "diol dimer" is intended to refer to a hydrogenated saturated diol derived from a corresponding diacid dimer (as defined above, and for example, a diacid dimer of at least one unsaturated fatty acid).

[0314] Industrially prepared diol dimers often contain other components, such as triol trimers, monohydric alcohols, and ether compounds, depending on the degree of purification of the acid dimers and / or their lower alcohol esters used as raw materials.

[0315] Typically, products with a glycol dimer content greater than 70% can be used in this invention. However, high-purity glycol dimers, such as compounds with a glycol dimer content greater than 90%, can be used.

[0316] Therefore, diol dimers can be produced by hydrogenation, for example by the catalytic hydrogenation of diacid dimers obtained by dimerization of at least one unsaturated fatty acid.

[0317] Suitable fatty acids can be, for example, those mentioned above, and for example, C8-C. 34 Fatty acids or, for example, C 12 -C 22 Fatty acids, or for example, C 16 -C 20 Fatty acids, especially C 18 fatty acid.

[0318] According to one embodiment, the diol dimer can be obtained from the hydrogenation of dimer linoleic acid.

[0319] Diol dimers can be, for example, dilinoleol.

[0320] Diol dimers can usually exist in a saturated form.

[0321] As another example of a diol dimer suitable for use in this invention, diglycerides may be mentioned, for example.

[0322] This compound is a glycerol dimer formed by the condensation of two glycerol molecules and the loss of a water molecule.

[0323] The term "diglyceride" refers to any combination of isomers that can be produced by such condensation, such as linear isomers, branched isomers, and, where appropriate, cyclic isomers produced by intramolecular dehydration of the diglyceride molecule.

[0324] Diglycerides can be obtained by any method known to those skilled in the art, and in particular those methods described in patent EP 0 750 848.

[0325] As examples of acid molecules that can interact with one or more hydroxyl functional groups of a polyol (without participating in the ester bond with the diacid dimer), molecules derived from isostearic acid, benzyl acid, phytostearic acid, stearic acid, or palmitic acid may be mentioned in a non-limiting manner.

[0326] The ester suitable for use in this invention can be obtained by reacting a polyol or its ester with a diacid dimer (and, for example, dimer dilinoleic acid) at a molar ratio of about 1.0:0.2-1.

[0327] An ester suitable for use in this invention can be obtained by reacting dimer linoleic acid with dimer linoleyl alcohol and, where appropriate, at least one additional monohydric alcohol, such as benzyl alcohol, isostearyl alcohol, phytosterol, stearyl alcohol and cetyl alcohol, and mixtures thereof.

[0328] Therefore, esters used in the context of this invention may be used, for example, in the form of mixtures of various esters.

[0473] Example 1 and Comparative Examples 1 and 2

[0474] [preparation]

[0475] The hair treatment compositions according to Example 1 (Ex.1) and Comparative Examples 1 and 2 (Comp.Ex.1 and Comp.Ex.2) were prepared by mixing the ingredients shown in Table 1. All values ​​for the amounts of ingredients are based on "wt%" as raw materials.

[0476] Table 1

[0477]

[0478]

[0479] *The value in parentheses indicates the amount (wt%) of amino-terminated polydimethylsiloxane with a low degree of polymerization (less than 2,000).

[0480] **The value in parentheses indicates the amount (wt%) of aminopropyl polydimethylsiloxane with a high degree of polymerization (greater than 3,000).

[0481] [Evaluate]

[0482] Three hair samples (hair bundles) (2.7 g, 27 cm) were prepared for each experiment. Each hair sample was washed once with a cleansing shampoo. After washing with shampoo, the hair samples were rinsed with water. Each hair sample was applied with the composition according to Example 1 and each of the compositions according to Comparative Examples 1 and 2 (1.1 g). The hair samples were left to stand for 5 minutes. The hair samples were rinsed under tap water and then allowed to air dry under ambient conditions to obtain the treated hair samples.

[0483] After the above treatment was performed on each of the compositions according to Example 1 and the compositions according to Comparative Examples 1 and 2 applied to the hair samples, combability, thickness, and adhesion were evaluated by three panel members according to the following criteria. The benchmarks represent the evaluation results for the hair samples themselves (i.e., without any composition applied).

[0484] 5: Much higher than the benchmark

[0485] 4: Higher than the benchmark

[0486] 3: Equivalent to the benchmark

[0487] 2: Below the benchmark

[0488] 1: Much lower than the benchmark

[0489] The scores obtained in this way are averaged. The results are shown in Table 1.

[0490] (result)

[0491] As can be seen from the results shown in Table 1, the composition according to Example 1, comprising triglycerides of hydroxylated fatty acids, oligomers of saturated diacids, and aminosilicone with a low degree of polymerization, provides improved conditioning effects, particularly with less heaviness and less stickiness. Furthermore, the composition according to Example 1 provides good combability for the hair.

[0492] The composition according to Comparative Example 1, comprising triglycerides of hydroxylated fatty acids, oligomers of saturated diacids, and amino silicone with a low degree of polymerization, provides a less desirable conditioning effect in terms of a heavier feel and greater adhesion. The amount of amino silicone raw material in the composition according to Comparative Example 1 is the same as the amount of amino silicone raw material in the composition according to Example 1. On the other hand, the composition according to Comparative Example 1 provides good combability for hair.

[0493] The composition according to Comparative Example 2, comprising oligomers of hydroxylated fatty acid triglycerides and saturated diacids, and amino silicone with a low degree of polymerization, provides a less desirable conditioning effect in terms of a heavier feel and greater adhesion. The amount of active ingredient (amino silicone) in the composition according to Comparative Example 2 is the same as the amount of active ingredient (amino silicone) in the composition according to Example 1. On the other hand, the composition according to Comparative Example 2 provides good combability for hair.
