Description

Title of the invention: USE OF POLYPHENOL AND WATER-SOLUBLE POLYMER FOR THE TREATMENT OF KERATIN FIBERS Technical field

[0001] The present invention relates to the use of a combination of polyphenol and a water-soluble polymer for the treatment of keratin fibers, preferably hair.

[0002] CONTEXT OF THE INVENTION

[0003] In the field of hair treatments, in some cases it is preferable to make the hair resistant or hard in order to improve, for example, the suppleness or elasticity of the hair. Furthermore, it is preferable for colored hair to be resistant to hair treatments such as washing and conditioning, in order to reduce color alteration due to these treatments.

[0004] JP-B-6594114 discloses a hair treatment with a pretreatment agent including tannic acid and a posttreatment agent including hydrolyzed keratin. According to JP-B-6594114, pretreating hair with tannic acid may reduce the penetration of hydrolyzed keratin into the hair. However, JP-B-6594114 does not disclose or imply that the two-step hair treatment disclosed therein may improve hair strength or reduce color fading in dyed hair.

[0005] There is a need for a hair treatment that can improve hair resistance. DISCLOSURE OF THE INVENTION

[0006] An objective of the present invention is to provide a means of improving the strength of keratin fibers such as hair and / or reducing the alteration of the color of dyed keratin fibers such as dyed hair.

[0007] The main objective can be achieved by a process for treating keratin fibers, preferably hair, comprising the steps of:

[0008] (1) treatment of keratin fibers by a first composition comprising at minus one polyphenol; and

[0009] (2) treatment of keratin fibers by a second composition comprising at minus a water-soluble polymer,

[0010] in which

[0011] the keratin fibers are treated by step (1) above followed by step (2) above.

[0012] The polyphenol can be selected from among the tannins.

[0013] It is preferable that the polyphenol be tannic acid.

[0014] The quantity of the polyphenol(s) in the first composition may be in a range of 0.01% to 10% by weight, preferably from 0.05% to 5% by weight, and more preferably from 0.1% to 3% by weight, relative to the total weight of the first composition.

[0015] The water-soluble polymer can be selected from water-soluble film-forming polymers, preferably from synthetic water-soluble film-forming polymers, and more preferably from the group consisting of polyvinyl alcohol, polyacrylic acid, polyvinylpyrrolidone (PVP), vinylpyrrolidone copolymers, and mixtures thereof.

[0016] It is even more preferable that the water-soluble polymer be polyvinylpyrrolidone.

[0017] It is preferable that the polyphenol and the water-soluble polymer form a gel.

[0018] The amount of the water-soluble polymer(s) in the second composition may be in a range of 0.01% to 10% by weight, preferably 0.05% to 5% by weight, and more preferably 0.1% to 3% by weight, relative to the total weight of the composition.

[0019] At least one of the first and second compositions may have a pH of 3.0 to 7.0, preferably 3.5 to 6.5, and more preferably 4.0 to 6.0.

[0020] The first composition can be removed from the keratin fibers after treatment of the keratin fibers with the first composition.

[0022] The process according to the present invention is capable of improving the resistance or hardness of keratin fibers.

[0023] The process according to the present invention is capable of reducing the alteration of the color of dyed keratin fibers.

[0024] The present invention also relates to a product for the treatment of keratin fibers, preferably hair, comprising

[0060] (Polyphenol)

[0061] The first composition comprises at least one polyphenol. Only one type of polyphenol may be used, or two or more different types of polyphenols may be used in combination.

[0062] The term "polyphenol" is understood to refer to a compound containing a plurality of phenolic hydroxyl groups. A phenolic hydroxyl group is defined as a hydroxyl group bonded to an aromatic ring such as a benzene ring or a naphthalene ring. The phenolic hydroxyl group may optionally be etherified or esterified.

[0063] The polyphenol can be chosen from those which have antioxidant activity.

[0064] The polyphenol can be chosen, for example, from among the flavonoids. The flavonoids may correspond to the general formula (I):

[0065] in which

[0066] A", B", C" and D", independently of each other, represent H or -OH;

[0067] E" represents H, -OH or -OX', where X' represents: -Œ

[0068] F", G", and J" represent, independently of each other, H or -OH; and

[0077] Certain polyphenols that can be used are present in plants from which they can be extracted in a known manner. Extracts of tea leaves (Camellia sinensis or Camellia japonica) can be used. In particular, green tea extracts sold under the name SUNPHENON® by the Nikko company, which contain flavonoids, can be mentioned.

[0078] Among the polyphenols that can be used, mention can also be made of polyphenols such as carnosic acid and camosol which can be extracted, for example, from rosemary, either by extraction followed by distillation (Chang et al., JOSC, Vol. 61, No. 6, June 1984) or by extraction with a polar solvent such as ethanol preceded by an extraction using a non-polar solvent such as hexane to remove odorous substances, as described in EP-A-307 626.

[0079] The polyphenol can also be selected from (2,5-dihydroxyphenyl)alkylenecarboxylic acids of formula (III) and their derivatives (in particular esters and amides): OH (III) OH

[0080] in which

[0081] Ri" represents -O-Alk, OH or -N(r')(r"), in which Alk designates a linear or branched Ci-C2O alkyl, optionally substituted by one or more hydroxyl groups or alkoxy groups, or a C2-C2O alkenyl,

[0082] r' and r" independently represent H, a CrC2O alkyl, a C2-C6 hydroxyalkyl or a C3-C6 polyhydroxyalkyl, or alternatively r' and r" form, together with a nitrogen atom to which they are attached, a heterocycle,

[0083] r is a number, including zero, such that the chain -(CH2)r-CORi contains at most 21 carbon atoms,

[0084] R2" and R3" independently represent H or an alkyl in Ci-C4, it being further It is possible for R2" to represent an alkoxy in Ci-C4.

[0086] The polyphenol can also be chosen from caffeic acid esters or amides.

[0087] Among the caffeic acid esters, we may in particular mention the compounds of formula (IV):

[0089] Z represents a Ci-C8 alkyl, for example a methyl, or the residue of a phytol.

[0090] Among the caffeic acid amides, the following compounds of formula (V) may be mentioned in particular:

[0091] in which

[0092] Z' represents an alkyl in CrC8, in particular in C6-C8.

[0275] Preferably, the nonionic surfactant may be a nonionic surfactant having an HLB of 8 to 18. The HLB is the ratio of the hydrophilic to the lipophilic portion in the molecule. This term HLB is well known to those skilled in the art and is described in "The HLB System: A Time-Saving Guide to Emulsifier Selection" (published by ICI Americas Inc., 1984).

[0335] (Oil)

[0336] The first composition and / or the second composition may comprise at least one oil. Only one type of oil may be used, or two or more different types of oils may be used in combination.

[0337] Here, "oil" means a fatty compound or oily substance that is in the form of a liquid or a paste (not a solid) at room temperature (25 °C) under atmospheric pressure (760 mmHg). Oils commonly used in cosmetics can be used alone or in combination. These oils can be volatile or non-volatile.

[0338] The oil may be a non-polar oil such as a hydrocarbon oil, a silicone oil, or other; a polar oil such as a vegetable or animal oil and an ester oil or an ether oil; or a mixture of these.

[0339] The oil may be selected from the group consisting of oils of vegetable or animal origin, synthetic oils, silicone oils, hydrocarbon oils and fatty alcohols.

[0340] Examples of oils of vegetable origin may be mentioned, for example, linseed oil, camellia oil, macadamia nut oil, corn oil, mink oil, olive oil, avocado oil, sasanqua oil, castor oil, safflower oil, jojoba oil, sunflower oil, almond oil, rapeseed oil, sesame oil, soybean oil, peanut oil, and mixtures thereof.

[0341] Examples of animal oils include, for example, squalene and squalane.

[0344] Preferably, for monoalcohol esters, at least one of the alcohol and acid from which the esters are derived is branched.

[0345] Among the monoesters of monoacids and monoalcohols, mention may be made of ethyl palmitate, ethylhexyl palmitate, isopropyl palmitate, dicaprylyl carbonate, alkyl myristates such as isopropyl myristate or ethyl myristate, isocetyl stearate, 2-ethylhexyl isononanoate, isononyl isononanoate, isodecyl neopentanoate and isostearyl neopentanoate.

[0348] As ester oils, sugar esters and diesters of C6-C3O fatty acids, and preferably C2-C22, may be used. It is recalled that the term "sugar" refers to hydrocarbon-based compounds bearing oxygen, containing several alcohol functional groups, with or without aldehyde or ketone functional groups, and comprising at least four carbon atoms. These sugars may be monosaccharides, oligosaccharides, or polysaccharides.

[0349] Examples of suitable sugars that may be mentioned include sucrose (or saccharose), glucose, galactose, ribose, fucose, maltose, fructose, mannose, arabinose, xylose and lactose, and derivatives thereof, in particular alkylated derivatives, such as methylated derivatives, for example methylglucose.

[0350] Sugar esters of fatty acids may be chosen in particular from the group comprising the esters or mixtures of esters of sugars described above and of linear or branched fatty acids, saturated or unsaturated, in C6-C3o and preferably in Ci2-C22. If they are unsaturated, these compounds may have one to three conjugated or non-conjugated carbon-carbon double bonds.

[0351] Esters according to this variant can also be selected from monoesters, diesters, triesters, tetraesters and polyesters, and mixtures thereof.

[0358] Preferably, the silicone oil is chosen from liquid polydialkylsiloxanes, in particular liquid polydimethylsiloxanes (PDMS) and liquid polyorganosiloxanes comprising at least one aryl group.

[0359] These silicone oils can also be organomodified. The organomodified silicones that can be used for the present invention are silicone oils as defined above and comprise in their structure one or more organofunctional groups attached via a hydrocarbon-based group.

[0360] Organopolysiloxanes are defined in more detail in Chemistry and Technology of Silicones by Walter Noll (1968), Academy Press. They can be volatile or non-volatile.

[0361] When volatile, silicones are particularly chosen from those having a boiling point between 60 °C and 260 °C, and even more particularly from:

[0362] (i) cyclic polydialkylsiloxanes comprising 3 to 7 and preferably of 4 to 5 silicon atoms. Examples include octamethylcyclotetrasiloxane, sold in particular under the name Volatile Silicone® 7207 by Union Carbide or Silbione® 70045 V2 by Rhodia; decamethylcyclopentasiloxane, sold under the name Volatile Silicone® 7158 by Union Carbide and Silbione® 70045 V5 by Rhodia; and dodecamethylcyclopentasiloxane, sold under the name Silsoft 1217 by Momentive Performance Materials, and mixtures thereof. Also noteworthy are cyclocopolymers such as dimethylsiloxane / methylalkylsiloxane, such as Silicone Volatile® FZ 3109, sold by Union Carbide, with the formula: p DD ——dg —; ÇHa '----------------------------ÇH; with D”: '"" SH O — with 0': """ St ™ O — CHg 0¾¾

[0363] We can also mention mixtures of cyclic polydialkylsiloxanes with organosilicon compounds, such as the (50 / 50) mixture of octamethylcyclotetrasiloxane and tetratrimethylsilylpentaerythritol and the mixture of octamethylcyclotetrasiloxane and oxy-1,1'-bis(2,2,2',2',3,3'-hexatrimethylsilyloxy)neopentane; and

[0364] (ii) linear volatile polydialkylsiloxanes containing 2 to 9 silicon atoms and having a viscosity less than or equal to 5 x 10⁶ m² / s at 25 °C. An example is decamethyltetrasiloxane, sold in particular under the name SH 200 by Toray Silicone. Silicones belonging to this category are also described in the article published in Cosmetics and Toiletries, Vol. 91, Jan. 1976, pp. 27–32, Todd & Byers, Volatile Silicone Fluids for Cosmetics. The viscosity of silicones is measured at 25 °C according to ASTM 445 Annex C.

[0365] Non-volatile polydialkylsiloxanes can also be used. These non-volatile silicones are more particularly chosen from among the polydialkylsiloxanes, among which the main ones to mention are the polydimethylsiloxanes containing trimethylsilyl terminal groups.

[0366] Among these polydialkylsiloxanes, the following commercial products may be mentioned, in a non-limiting manner:

[0371] We can also mention polydimethylsiloxanes containing dimethylsilanol terminal groups known as dimethiconol (CTFA), such as the 48 series oils from the Rhodia company.

[0372] Among silicones containing aryl groups, mention may be made of polydiarylsiloxanes, in particular polydiphenylsiloxanes and polyalkylarylsiloxanes such as phenyl silicone oil.

[0373] The phenyl silicone oil may be selected from the phenyl silicones of the following formula:

[0384] As a phenyl silicone oil, a phenyl trimethicone (Ri to Rio are a methyl;p, qetn = 0;m=l in the formula above) is preferable.

[0385] Organomodified liquid silicones may, in particular, contain polyethyleneoxy and / or polypropyleneoxy groups. Examples include KF-6017 silicone offered by Shin-Etsu, and Silwet® L722 and L77 oils from Union Carbide.

[0386] Hydrocarbon oils may be selected from:

[0390] The term "fatty" in fatty alcohols refers to the inclusion of a relatively large number of carbon atoms. Thus, alcohols with 4 or more carbon atoms, preferably 6 or more, and more preferably 12 or more, are encompassed within the scope of fatty alcohols. Fatty alcohols can be saturated or unsaturated. Fatty alcohols can be linear or branched.

[0391] The fatty alcohol may have the structure R-OH in which R is selected from saturated and unsaturated, linear and branched radicals containing from 4 to 40 carbon atoms, preferably from 6 to 30 carbon atoms, and more preferably from 12 to 20 carbon atoms. In at least one embodiment, R may be selected from alkyl groups in the form C2-C2O and alkenyl groups in the form C2-C2O. R may or may not be substituted by at least one hydroxyl group.

[0392] Examples of fatty alcohols may be mentioned, such as lauryl alcohol, cetyl alcohol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, undecylenyl alcohol, myristyl alcohol, octyldodecanol, hexyldecanol, oleyl alcohol, linoleyl alcohol, palmitoleyl alcohol, arachidonylic alcohol, erucyl alcohol, and mixtures thereof.

[0393] It is preferable that the fatty alcohol be a saturated fatty alcohol.

[0394] Thus, the fatty alcohol can be selected from C6-C30 alcohols, linear or branched, saturated or unsaturated, preferably C6-C30 saturated alcohols, linear or branched, and more preferably Ci2-C20 saturated alcohols, linear or branched.

[0395] The term "saturated fatty alcohol" here refers to an alcohol having a long aliphatic saturated carbon chain. Preferably, the saturated fatty alcohol should be selected from any linear or branched C6-C30 saturated fatty alcohol. Among linear or branched C6-C30 saturated fatty alcohols, linear or branched Ci2-C20 saturated fatty alcohols may preferably be used. Any linear Ci6-C20 saturated fatty alcohol or branched, may be used more preferably. C16-C20 branched fatty alcohols may be used even more preferably.

[0396] Examples of saturated fatty alcohols include lauryl alcohol, cetyl alcohol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, undecylenyl alcohol, myristyl alcohol, octyldodecanol, hexyldecanol, and mixtures thereof. In one embodiment, cetyl alcohol, stearyl alcohol, octyldodecanol, hexyldecanol, or a mixture thereof (e.g., cetearyl alcohol), as well as behenyl alcohol, may be used as saturated fatty alcohols.

[0397] According to at least one embodiment, the fatty alcohol used in the composition for the present invention is preferably chosen from cetyl alcohol, cetearyl alcohol, octyldodecanol, hexyldecanol, and mixtures thereof.

[0398] The oil may be selected from non-polar or polar oils, preferably hydrocarbon oils, silicone oils, ester oils, and mixtures thereof, and even more preferably isododecane, isohexadecane, dimethicone, diisopropyl sebacate and mixtures thereof.

[0400] The quantity of oil (oils) in the composition may be 25% by weight or less, preferably 20% by weight or less, and more preferably 15% by weight or less, relative to the total weight of the composition.

[0401] The quantity of oil (oils) in the composition may be from 0.01% to 25% by weight, preferably from 0.05% to 20% by weight, and more preferably from 0.1% to 15% by weight, relative to the total weight of the composition.

[0402] (Other optional ingredients)

[0403] The first composition and / or the second composition may also include any optional ingredients conventionally used in cosmetics for keratin fibers such as hair, such as anionic, non-ionic, cationic, amphoteric or zwitterionic polymers, or mixtures thereof; antioxidants; thickening agents; sequestering agents; perfumes; dispersing agents; an acidic agent, an alkali agent, film-forming agents; ceramides; preservatives; and opacifying agents.

[0404] {Preparation}

[0405] Each of the first and second compositions can be prepared by mixing the essential ingredient(s) as explained above, and the optional ingredient(s) as explained above.

[0406] The method and means of mixing the above essential and optional ingredients are not limited. Any conventional method and means may be used to mix the above essential and optional ingredients to prepare the first and second compositions.

[0407] {Form}

[0408] The first composition and / or the second composition may be in the form of a cosmetic composition, preferably a hair cleansing composition and a hair care composition, and more preferably a shampoo and conditioner.

[0409] The composition according to the present invention may be of the no-rinse or rinse-off type. The no-rinse composition is not rinsed after being used on keratin fibers. The rinse-off composition is rinsed after being used on keratin fibers.

[0410] It is preferable that the composition which is applied first to keratin fibers be a shampoo, and that the composition which is applied second to keratin fibers be a conditioner.

[0411] {Processing steps}

[0412] According to the present invention, keratin fibers such as hair are treated by the first and second compositions.

[0413] The method according to the present invention comprises the steps of:

[0414] (1) treatment of keratin fibers by a first composition comprising at minus one polyphenol; and

[0415] (2) treatment of keratin fibers by a second composition comprising at minus a water-soluble polymer,

[0416] in which

[0417] Keratin fibers are treated by step (1) above followed by step (2) above.

[0418] In other words, the process according to the present invention can be carried out by:

[0419] (a) treatment of keratin fibers first with the first composition,

[0420] and then,

[0421] (b) treatment of keratin fibers first with the second composition.

[0422] The first composition can be removed from the keratin fibers after treatment of the keratin fibers with the first composition.

[0423] Thus, it is possible, if necessary, to perform a rinsing step between the treatment of the keratin fibers with the first composition and the treatment of the keratin fibers with the second composition. After the rinsing step, a drying step can be performed before the subsequent treatment of the keratin fibers with the second composition.

[0424] Moreover, the first composition can be maintained on the keratin fibers after treatment of the keratin fibers with the first composition.

[0425] After steps (a) and (b) above, a rinsing step may or may not be performed. If a rinsing step is performed, a drying step may be performed, if necessary, after the rinsing step.

[0426] The process according to the present invention is not a permanent reshaping process such as permanent waving or smoothing for keratin fibers.

[0427] The keratin fibers to which each of the first and second compositions has been applied can be left for an appropriate time as required to treat the keratin fibers. The duration for each treatment is not limited, but it can be from 1 to 30 minutes, preferably from 1 to 20 minutes, and more preferably from 1 to 10 minutes. Thus, for example, the total time for the treatments according to the present invention can be from 3 to 60 minutes, preferably from 3 to 40 minutes, and more preferably from 3 to 20 minutes.

[0428] Keratin fibers can be treated at room temperature. Alternatively, keratin fibers can be heated to 25 °C to 65 °C, preferably 30 °C to 60 °C, more preferably 35 °C to 55 °C, and even more preferably 40 °C to 50 °C, before and / or during and / or after the application step of each of the first and second compositions on the keratin fibers.

[0429] The above process is preferably intended for cosmetic purposes for keratin fibers, for example, for the cosmetic treatment of keratin fibers, such as hair, other than a permanent reshaping of keratin fibers.

[0430] The process according to the present invention can improve the strength of keratin fibers such as hair and / or reduce the alteration of the color of dyed keratin fibers such as dyed hair.

[0431] It is possible, by means of the process according to the present invention, to endow keratin fibers such as hair with improved strength or hardness. Thus, the process according to the present invention can endow keratin fibers with improved cosmetic properties such as greater suppleness and elasticity.

[0432] It is also possible, by means of the process according to the present invention, to endow dyed keratin fibers, such as dyed hair, with resistance to hair treatments such as washing and conditioning. Thus, the process according to the present invention can provide dyed keratin fibers exhibiting less color alteration than a process in which the first compositions one not including polyphenol and the second composition not including plant-derived protein are used.

[0466] (2) treatment of keratin fibers by at least one water-soluble polymer

[0467] in order to improve the strength or hardness of keratin fibers and / or to reduce the alteration of the color of keratin fibers.

[0468] The above combination can improve, for example, the suppleness or elasticity of keratin fibers such as hair and / or reduce the alteration of the color of keratin fibers such as hair due to certain activities such as shampooing and conditioning of keratin fibers.

[0469] The processing steps (1) and (2) above are carried out separately and sequentially. In other words, steps (1) and (2) above are not carried out simultaneously.

[0470] The above product, kit and use are preferably intended for cosmetic purposes for keratin fibers, for example, for the cosmetic treatment of keratin fibers, such as hair, other than permanent reshaping of keratin fibers.

[0490] [Evaluations]

[0491] A sensory test was carried out by five panelists to evaluate the resistance (hardness) of the hair strands after the hair treatments according to Examples 1 to 8 and Comparative Examples 1 to 5 by comparing the hair strands with a hair strand without any hair treatment whose score was determined to be 3 as a reference (standard), and determination of the score of the relative resistance of hair fibers in accordance with the following criteria.

[0492] 5: much stronger than the resistance of an untreated strand of hair

[0493] 4: stronger than the resistance of an untreated strand of hair

[0494] 3: similar to the resistance of an untreated strand of hair

[0495] 2: more fragile than the resistance of an untreated strand of hair

[0496] 1: much more fragile than the resistance of an untreated strand of hair

[0497] The average scores were calculated. A higher score indicates hair fibers perceived as being more resistant. The results are shown in Tables 4-6 below.

[0513] Hair colouring tests (Example 9 and Comparative Example 6)

[0514] Strands of hair having identical properties were placed on a heated plate at 27 °C. A 1:1 mixture (weight ratio) of an oxidative colouring product (Alluria Ash Blue 8.11 shade 8, L'Oreal Professional) and an oxidizing product (Alluria Cream Oxydant, L'Oreal Professional) was applied to each of the hair strands at a ratio of 3 g of mixture / g of hair, and the hair strands were left for 30 minutes until rinsed with tap water (37 °C) to prepare coloured hair strands.

[0515] The above coloured hair strands were treated as shown in Table 9. The coloured hair strands were washed with Shampoo Composition 1 (Ex. 9) or Shampoo Composition 2 (Ex. Comp. 6) at a ratio of 0.4 g of shampoo / g of hair, and rinsed with tap water (37 °C).

[0516] Then, without drying, Conditioner Composition 1 (Ex. 9) or Conditioner Composition 2 (Ex. Comp. 6) was applied to the colored hair strands at a ratio of 0.4 g of conditioner / g of hair and left for 5 minutes under ambient conditions (25 °C, RH 40%).

[0517] The above shampoo and conditioner were repeated.

[0518] Finally, the colored hair strands were dried with a hairdryer.

[0520] [Evaluations]

[0521] In Example 9, a colour alteration analysis was performed on the coloured hair strand that had been subjected to an oxidative dye as above, determining the colour change (AE*) before and after treatment of the coloured hair strand with a shampoo including tannic acid (Shampoo Composition 1) and a conditioner including PVP (Conditioner Composition 1).

[0522] In Comparative Example 6, a colour alteration analysis was performed on the coloured hair strand that had been subjected to an oxidative dye as above, determining the colour change (AE*) before and after treatment of the coloured hair strand with a shampoo not including tannic acid (Shampoo Composition 2) and a conditioner including no PVP (Conditioner Composition 2).

[0523] The color difference (AE* based on CIE1976) was measured using a Konica Minolta CM-3600A. A smaller AE* indicates less color alteration. The results are shown in Table 9.

[0524] At every point in the treatment, the use of a shampoo including tannic acid and a conditioner including PVP showed lower AE* values ​​(less color alteration) compared to the use of a shampoo not including tannic acid and a conditioner not including PVP.

[0525] The foregoing demonstrates that the use of a shampoo including tannic acid and a conditioner including PVP for coloured hair can provide less colour alteration.
