Description

[Technical field]

[0001] The present invention relates primarily to a method for treating, preferably for reshaping, and more preferably for straightening, keratinous fibers such as hair. [Background technology]

[0002] Reshaping keratinous fibers such as hair by heating them with an iron is popular for making unruly keratinous fibers easier to manage, reducing the volume of keratinous fibers, and making them look more desirable.The reshaping method using a heating iron is convenient for quick styling, but it is not easy to obtain a sufficient reshaping effect.

[0003] On the other hand, the conventional permanent reshaping method using reducing and alkaline agents and oxidizing agents and heating can bring about an improved reshaping effect to keratin fibers, but has some drawbacks such as long processing time, damage to keratin fibers and bad odor.

[0004] Several methods have been reported to reshape keratin fibers without the use of reducing and oxidizing agents.

[0005] For example, JP-A-2020-066575, an acid treatment comprising applying an acidic first hair composition to the hair, the first hair composition comprising an acid and / or a salt thereof; A washing process for washing the hair; a silicone treatment in which a second hair composition, which is a liquid containing silicone, is applied to the hair; A drying process for drying the hair; a heat treatment in which the hair is contacted with a heating element having a preset temperature of at least 100°C; A method for treating hair is disclosed, comprising:

[0006] In addition, US-A-2012-312317 is a) applying a solution comprising an operable alpha-keto acid as a buffer; b) maintaining the solution in contact with the hair for 15 to 120 minutes; c) drying the hair; d) straightening the hair with a straightening iron having a temperature of about 200 + / - 50°C; The present invention discloses a method for semi-permanent hair straightening, comprising:

[0007] In addition, JP-A-2019-123701 is (1) applying to hair a hair treatment agent containing (a) 13 to 30% by mass of levulinic acid and (b) 1 to 2% by mass of glyoxylic acid, the total content of levulinic acid and glyoxylic acid being 15% by mass or more, and having a pH in the range of 1.5 to 3.0; (2) leaving the hair; (3) washing the hair with water; (4) Simultaneously with or after drying the hair, straightening the hair using a hair styling or straightening iron, brush, or the like at a specific temperature.

[0028] The present invention also relates to the use of a combination of composition A and composition B for reshaping, preferably straightening, keratinous fibers such as hair, comprising: Composition A is (a) at least one silicone, and (b) at least one vegetable oil; Including, Composition B is (c) at least one compound selected from the group consisting of glyoxylic acid, glyoxylic acid solvates, glyoxylates, glyoxylate esters, glyoxylate amides, and mixtures thereof; and (d) at least one compound selected from the group consisting of keto acids, salts thereof, and mixtures thereof, different from compound (c). It also relates to use, including DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] After extensive investigation, the inventors have discovered that it is possible to provide a method for reshaping keratinous fibers, which is capable of providing an improved reshaping effect on the keratinous fibers by applying two different compositions, composition A and composition B, wherein composition A comprises at least one silicone and at least one vegetable oil, and composition B comprises at least one glyoxylic acid or a derivative thereof and at least one keto acid or a salt thereof.

[0030] The present invention therefore relates primarily to a method for reshaping, preferably straightening, keratinous fibres such as hair, comprising the steps of: (i) applying composition A to keratinous fibers, said composition A comprising: (a) at least one silicone, and (b) at least one vegetable oil; and (ii) applying composition B to keratinous fibers, said composition B comprising: (c) at least one compound selected from the group consisting of glyoxylic acid, glyoxylic acid solvates, glyoxylates, glyoxylate esters, glyoxylate amides, and mixtures thereof; and (d) at least one compound selected from the group consisting of keto acids, salts thereof, and mixtures thereof, different from compound (c). and (iii) optionally heating the keratin fibers at a temperature above 50° C., preferably above 100° C., more preferably above 150° C.; Including, The present invention relates to a process comprising step (i) followed by step (ii) or step (ii) followed by step (i).

[0031] The present invention makes it possible to improve the method for reshaping keratinous fibers, such as hair, by applying two different compositions, Composition A and Composition B, by providing an improved reshaping effect.

[0032] Reshaping keratinous fibers, such as hair, as used herein includes straightening or curling the keratinous fibers.

[0033] In addition, the method according to the present invention can provide keratinous fibers, such as hair, with better keratinous fiber cohesion, leading to easier combing of the keratinous fibers and easier application of a hair iron to the keratinous fibers.

[0034] The present invention does not require the use of any reducing / oxidizing agents, and therefore can cause less damage to keratin fibers compared to conventional hair straightening methods. Therefore, it can be easier to comb keratin fibers treated by the present invention. Therefore, keratin fibers treated by the present invention can be easily handled.

[0035] In addition, the present invention may not use ammonia or thiol compounds or may use very little of them, and therefore, compared with the conventional methods that require the use of ammonia or thiol compounds, the odor during use of the present invention can be reduced.The present invention also allows for good ease of use, such as short processing time.

[0036] The present invention will be described in detail below.

[0037] [method] The present invention relates to a method for reshaping, preferably straightening, keratinous fibers, preferably hair, comprising the steps of: (i) applying composition A to keratinous fibers, said composition A comprising: (a) at least one silicone, and (b) at least one vegetable oil; and (ii) applying composition B to keratinous fibers, said composition B comprising: (c) at least one compound selected from the group consisting of glyoxylic acid, glyoxylic acid solvates, glyoxylates, glyoxylate esters, glyoxylate amides, and mixtures thereof; and (d) at least one compound selected from the group consisting of keto acids, salts thereof, and mixtures thereof, different from compound (c). and (iii) optionally heating the keratin fibers at a temperature above 50° C., preferably above 100° C., more preferably above 150° C.; Including, The present invention relates to a process comprising step (i) followed by step (ii) or step (ii) followed by step (i).

[0038] The method according to the invention aims at reshaping keratin fibres such as hair, preferably for a long period of time, more preferably even after washing, in which sense the method according to the invention can be a semi-permanent reshaping method.

[0039] Process (i) Step (i) is a step for applying to keratin fibers composition A. Composition A will be described in detail below.

[0040] Application of Composition A may be carried out by any means, such as with a brush or comb.

[0041] The liquor ratio of the applied composition A to the keratinous fibers may range from 0.1 to 10, more particularly from 0.5 to 5, preferably from 0.3 to 2. The term "liquor ratio" is intended to mean the mass ratio between the total mass of the applied composition and the total mass of the keratinous fibers.

[0042] The amount of composition A applied to the keratin fibers is not particularly limited, but is generally in the range of 0.1 g to 1 g per 1 g of keratin fibers.

[0043] In one embodiment of the present invention, the keratinous fibers are washed prior to step (i). This washing step can be carried out, for example, by washing the keratinous fibers with a shampoo, followed by rinsing the keratinous fibers. After rinsing, the keratinous fibers may be dried. The keratinous fibers are preferably wet immediately prior to step (i). The washing step is preferably carried out once prior to carrying out the method of the present invention.

[0044] After application of composition A, the keratinous fibers may be left in place, if necessary, for a particular length of time, typically from 1 second to 10 minutes, preferably from 5 seconds to 5 minutes, and more preferably from 10 seconds to 3 minutes, to allow composition A to penetrate into the keratinous fibers.

[0045] Composition A may or may not be rinsed from the keratinous fibers after step (i). In one embodiment of the invention, after step (i), the keratinous fibers are rinsed with water to rinse the applied composition A from the keratinous fibers.

[0046] Process (ii) Step (ii) is a step for applying to keratin fibers composition B. Composition B will be described in detail below.

[0047] Application of Composition B may be carried out by any means, such as with a brush or comb.

[0048] The liquor ratio of the applied composition B to the keratinous fibers may range from 0.1 to 10, more particularly from 0.5 to 5, preferably respectively from 0.3 to 2. The term "liquor ratio" is intended to mean the mass ratio between the total mass of the applied composition and the total mass of the keratinous fibers.

[0049] The amount of composition B applied to the keratin fibers is not particularly limited, but is generally in the range of 0.1 g to 1 g per 1 g of keratin fibers.

[0050] In one embodiment of the present invention, the keratinous fibers are washed prior to step (ii). This washing step can be carried out, for example, by washing the keratinous fibers with shampoo, followed by rinsing the keratinous fibers. After rinsing, the keratinous fibers may be dried. The keratinous fibers are preferably wet immediately prior to step (ii).

[0051] After application of composition B, the keratinous fibers may be left in place, if necessary, for a certain length of time, typically from 1 second to 30 minutes, preferably from 5 seconds to 20 minutes, and more preferably from 10 seconds to 15 minutes, to allow composition B to penetrate into the keratinous fibers.

[0052] Composition B may or may not be rinsed from the keratinous fibers after step (ii). In one embodiment of the invention, after step (ii), the keratinous fibers are rinsed with water to rinse the applied composition B from the keratinous fibers.

[0053] In a preferred embodiment, there is no washing step between steps (i) and (ii).

[0054] In one embodiment of the invention, the method comprises step (i) followed by step (ii), in that order, and in this embodiment, preferably no rinsing step is included between steps (i) and (ii).

[0055] In one embodiment of the invention, the method comprises step (ii) followed by step (i), in that order, and in this embodiment preferably includes a rinsing step between steps (ii) and (i).

[0056] In another preferred embodiment, the method comprises step (i) followed by step (ii) followed by step (i) again, in that order, and in this embodiment, it is preferred that no rinsing step is included between steps (i) and (ii) and that a rinsing step is included between steps (ii) and (i).

[0057] Process (iii) Step (iii) is an optional step, which consists in heating the keratin fibers at a temperature above 50° C., preferably above 100° C., more preferably above 150° C. Step (iii) can be carried out after both steps (i) and (ii) have been completed.

[0058] In one embodiment, the keratinous fibers are dried immediately prior to step (iii). Drying the keratinous fibers can be carried out by conventional drying means such as a hair dryer.

[0059] In step (iii), the keratinous fibers, which are preferably dry, are heated with a heater, preferably a heated iron or heated curlers, at a temperature of more than 50° C., preferably more than 100° C., more preferably more than 150° C. This temperature may be less than 250° C., preferably less than 240° C., more preferably less than 230° C. Thus, the temperature may be more than 50° C. and less than 250° C., preferably more than 100° C. and less than 240° C., more preferably more than 150° C. and less than 230° C.

[0060] Heating can be accomplished by conventional means, such as by application of heated irons or curlers or hair dryers.

[0061] Reshaping can also be performed by applying some mechanical force, such as mechanical tension, to the keratinous fibers. The mechanical force can be applied to the keratinous fibers by any reshaping means that transforms the keratinous fibers into an intended shape. For example, the mechanical power can be applied by at least one reshaping means selected from the group consisting of at least one iron, at least one curler, and combinations thereof. As the reshaping means, any conventional iron or curler can be used.

[0062] The reshaping means may comprise at least one heater. Thus, the reshaping means may be at least one heated iron and / or at least one heated curler. By reshaping the keratinous fibres, the keratinous fibres may be straightened or curled. Thus, the method according to the invention may be aimed at straightening or curling keratinous fibres, such as hair.

[0063] The heating iron may be any conventional heating iron. The heating iron may have at least one plate, preferably two plates, which may be heated, for example, by electric heat. The heated plate may be applied onto keratin fibers and moved along the direction of the keratin fibers to straighten the keratin fibers.

[0064] The heating iron preferably has two plates, and the keratin fibers are sandwiched between the two plates of the heating iron, at least one of which can be heated, and then the two plates are moved along the direction of the keratin fibers to straighten the keratin fibers.

[0065] It is preferred that the heating iron, and in particular the part thereof (such as one or more heating plates) in contact with the keratinous fibers, has a temperature above 50°C and below 250°C, more preferably above 100°C and below 240°C, even more preferably above 150°C and below 230°C.

[0066] Step (iii) can be carried out by one or more strokes of the heating iron moving along the direction of the keratinous fibers. Step (iii) can be controlled not only by the temperature of the heating iron but also by the number of strokes of the heating iron.

[0067] The heating time may depend on the temperature of the heating iron, but also on the number of strokes of the heating iron, and may be, for example, from 1 second to 10 minutes, preferably from a few seconds to 5 minutes.

[0068] As the heating curler, any conventional heating curler may be used. When the keratin fibers are wound around the heating curler, this winding may be performed over the entire length of the keratin fibers or, for example, over half the length of the keratin fibers. For example, the winding may be performed in more or less thick bundles, depending on the shape of the desired hairstyle and the amount of curl.

[0069] The heating curler, particularly parts thereof (such as the heating rod and heating cover) that come into contact with the keratin fibers, preferably has a temperature of more than 50°C and less than 250°C, more preferably more than 100°C and less than 240°C, even more preferably more than 150°C and less than 230°C.

[0070] Step (iii) can be carried out by maintaining the keratinous fibers on heated curlers and thus applying a mechanical tension to the keratinous fibers. Step (iii) can be controlled not only by the temperature of the heated curlers but also by the strength of the mechanical tension.

[0071] The heating time may be determined by the temperature of the heating curler, but also by the strength of the mechanical tension, and may be, for example, from 1 second to 10 minutes, preferably from a few seconds to 5 minutes.

[0072] Optionally, prior to step (iii), mechanical tension may be applied to the keratinous fibers as explained above.

[0073] Compositions A and B used in the method according to the present invention will now be described in detail.

[0074] Composition A Composition A of the present invention is (a) at least one silicone, and (b) at least one vegetable oil; Includes.

[0080] The pH of the composition used in the present invention may be from 3 to 8, preferably from 4 to 7, more preferably from 4.5 to 6, measured at 25°C.

[0081] The components of Composition A are described in detail below.

[0082] (a) Silicone Composition A in the method according to the invention comprises at least one silicone. Two or more silicones may be included in composition A. Thus, a single type of silicone or a combination of different types of silicones may be used in composition A.

[0083] In the context of the present invention, the term "silicone" as used herein is understood to mean, according to the generally accepted definition, all organosilicon polymers or oligomers with linear or cyclic, branched or crosslinked structure of variable molecular weight obtained by polymerization and / or polycondensation of appropriately functionalized silanes, which essentially contain a repetition of the main units (siloxane bonds ≡Si-O-Si≡) whose silicon atoms are bonded together with each other through oxygen atoms, and optionally substituted hydrocarbon groups are bonded directly to the silicon atoms through carbon atoms. The most common hydrocarbon groups are alkyl groups, especially C1-C 10 These are alkyl groups, especially methyl groups, fluoroalkyl groups and aryl groups, especially phenyl groups.

[0084] The (a) silicone may be selected from silicone oils.

[0085] In this specification, "silicone oil" means a silicone compound or substance that is in the form of a liquid or paste at atmospheric pressure (760 mmHg) and room temperature (25°C). As silicone oil, those commonly used in cosmetics can be used alone or in combination.

[0086] Silicones or organopolysiloxanes are defined, for example, by Walter NOLL in "Chemistry and Technology of Silicones", Academic Press, 1968. They may be volatile or non-volatile.

[0087] Thus, the silicone oil may be selected from volatile silicones, non-volatile silicones, and mixtures thereof.

[0088] Thus, the silicone oil may comprise either at least one volatile silicone oil or at least one non-volatile silicone oil, or may comprise both at least one volatile silicone oil and at least one non-volatile silicone oil.

[0089] The volatile or non-volatile silicone may be selected from linear, branched, or cyclic silicones, optionally modified with at least one organofunctional moiety or group. (a) The silicone is preferably non-volatile.

[0090] For example, the silicone oil can be selected from the group consisting of polydialkylsiloxanes, such as polydimethylsiloxane (PDMS), polyalkylarylsiloxanes, such as phenyltrimethicone, polydiarylsiloxanes; and organically modified polysiloxanes comprising at least one organofunctional moiety or group selected from poly(oxyalkylene) moieties or groups, alkoxy or alkoxyalkyl moieties or groups, hydroxy or hydroxylated moieties or groups, acyloxy or acyloxyalkyl moieties or groups, carboxylic acid or carboxylate moieties or groups, acrylic moieties or groups, and oxazoline moieties.

[0091] The silicone oil may be selected from non-volatile silicones, such as polydialkylsiloxanes, polyalkylarylsiloxanes, polydiarylsiloxanes, and organomodified polysiloxanes as described above.

[0094] The silicone (c) preferred according to the present invention has a viscosity of 1,000,000 cSt (mm 2 The oil may be a polydimethylsiloxane having trimethylsilyl end groups, such as an oil having a viscosity at 25° C. of more than 1 / s), even more preferentially more than 2,000,000 cSt, even more particularly more than 5,000,000 cSt, better still more than 10,000,000 cSt, and preferably less than 50,000,000 cSt, even better still less than 30,000,000 cSt, and even better still less than 15,000,000 cSt.

[0095] According to the invention, all polydimethylsiloxanes can be used as such or in the form of a solution, emulsion, nanoemulsion or microemulsion.

[0387] The present invention will now be described in more detail with reference to examples, which should not be construed as limiting the scope of the present invention.

[0388] [Preparation] Compositions A and A' and Composition B were prepared by mixing the components shown in Tables 1 and 2. All component amounts are based on "mass %" of the ingredients.

[0389] [Table 1]

[0390] [Table 2]

[0391] (Examples 1 to 3 and Comparative Examples 1 to 7) Example 1 1 g of Brazilian curly hair swatches (Type IV) 27 cm in length were washed with 0.5 g of plain shampoo. The formula for the plain shampoo is shown in Table 3 below. All values ​​for component amounts are based on "wt %" of the ingredients. The hair swatches were rinsed thoroughly with tap water.

[0392] [Table 3]

[0393] An amount of 0.2 g of composition A was applied to wet hair swatches as a pre-treatment (step (i)).

[0394] Then, without rinsing, an amount of 0.6 g of Composition B was applied to the hair swatch (step (ii)).

[0395] The hair swatches were left for 10 minutes at room temperature (25° C.) The hair swatches were then thoroughly rinsed with tap water and then dried with a hair dryer until the hair swatches were dry.

[0396] The hair swatches were subjected to straightening by applying 3 strokes of a hair straightening iron (ADST Premium DS2 from Hakko Co., Ltd., Japan) at 180° C., 4 seconds / stroke (step (iii)).

[0397] Comparative Example 1 The same hair swatches as those used in Example 1 were washed with 0.5 g of the plain shampoo according to Example 1. The formula of the plain shampoo was the same as that used in Example 1. Then, no treatment was applied to the hair swatches according to Comparative Example 1. Therefore, steps (i) to (iii) were not performed in this process.

[0398] Comparative Example 2 The sample according to Comparative Example 2 was prepared by washing the hair with 0.5g of the plain shampoo according to Example 1, and then drying the hair swatch with a hair dryer until the hair swatch was dry.The hair swatch was then subjected to straightening using a straightening iron without any treatment.The straightening process was the same as that of Example 1.Therefore, in this process, only step (iii) was carried out.

[0399] Comparative Example 3 The sample according to Comparative Example 3 was prepared in the same manner as in Example 1, but without the pretreatment with Composition A. Therefore, step (i) was not carried out in this process.

[0400] Comparative Example 4 The sample according to Comparative Example 4 was prepared in the same manner as in Example 1, except that in the pre-treatment step, Composition A' was used instead of Composition A. Therefore, in this process, step (i) of the present invention using (a) silicone and (b) vegetable oil was not carried out.

[0401] Example 2 The sample according to Example 2 was prepared in the same manner as Example 1, using Chinese curly hair swatches (Type III) instead of Brazilian curly hair swatches (Type IV).

[0402] Example 3 Example 2 was repeated, but after rinsing off composition B with tap water, 0.25 g of hair care composition Y was applied to the hair swatch. The hair swatch was left at room temperature (25° C.) for 5 minutes and then rinsed thoroughly with tap water. 0.03 g of hair care composition Z was then applied to the hair swatch. The hair swatch was then dried with a hair dryer and subjected to straightening in the same manner as in Example 1.

[0403] Therefore, the process according to Example 3 included an additional step (iv).

[0404] The formulations of Hair Care Compositions Y and Z are shown below in Tables 4 and 5, respectively. All component amounts are based on "wt %" of the ingredients.

[0405] [Table 4]

[0406] [Table 5]

[0407] Comparative Example 5 Example 2 was repeated, except that in this process step (i) was not carried out.

[0408] Comparative Example 6 Example 2 was repeated, but in the pre-treatment step, composition A' was used instead of composition A. Therefore, step (i) of the present invention, which uses (a) silicone and (b) vegetable oil, was not carried out in this process.

[0409] Comparative Example 7 Example 3 was repeated, but in the pre-treatment step, composition A' was used instead of composition A. Therefore, step (i) of the present invention, which uses (a) silicone and (b) vegetable oil, was not carried out in this process.

[0410] The processes according to Examples 1-3 and Comparative Examples 1-7 are summarized in Table 6. As explained above, in these examples, steps (i), (ii), (iv), and (iii) were carried out in this order (if present).

[0411] [Table 6]

[0412] (Examples 4 and 5 and Comparative Examples 8 and 9) Example 4 1 g of Chinese curly hair swatch (Type III) with a length of 27 cm was washed with 0.5 g of plain shampoo, the formula of which was the same as that used in Example 1.

[0413] An amount of 0.6 g of composition B was applied to wet hair swatches as a pre-treatment (step (ii)).

[0414] The hair swatches were left at room temperature (25° C.) for 10 minutes and then rinsed thoroughly with tap water.

[0415] An amount of 0.2 g of Composition A was applied to the hair swatches as a post-treatment (step (i)).

[0416] The hair swatches were then rinsed thoroughly again with tap water and then dried with a hair dryer until the hair swatches were dry.

[0417] The hair swatches were subjected to straightening by applying 3 strokes of a hair straightening iron (ADST Premium DS2 from Hakko Co., Ltd., Japan) at 180° C., 4 seconds / stroke (step (iii)).

[0418] Example 5 Example 4 was repeated, but then 0.25 g of hair care composition Y was applied to the hair swatch after rinsing composition A with tap water. The hair swatch was left at room temperature (25° C.) for 10 minutes and then rinsed thoroughly with tap water. 0.003 g of hair care composition Z was then applied to the hair swatch. The hair swatch was left at room temperature (25° C.) for 10 minutes. The hair swatch was then dried with a hair dryer and subjected to straightening in the same manner as in Example 1.

[0419] Therefore, the process according to Example 4 included an additional step (iv).

[0420] The formulations of Hair Care Compositions Y and Z were the same as those used in Example 3, shown above in Tables 4 and 5, respectively.

[0421] Comparative Example 8 Example 4 was repeated, but in the post-treatment step, composition A' was used instead of composition A. Therefore, step (i) of the present invention, which uses (a) silicone and (b) vegetable oil, was not carried out in this process.

[0422] Comparative Example 9 Example 5 was repeated, but in the post-treatment step, composition A' was used instead of composition A. Therefore, step (i) of the present invention, which uses (a) silicone and (b) vegetable oil, was not carried out in this process.

[0423] The processes according to Examples 4 and 5 and Comparative Examples 8 and 9 are summarized in Table 7. As explained above, in these examples, steps (ii), (i), (iv), and (iii) were carried out in this order (if present).

[0424] [Table 7]

[0425] [evaluation] (Hair straightening effect) After each treated hair swatch was kept at room temperature (25°C) for 3 hours, the straightening level of the treated hair swatches was visually evaluated based on three aspects: "straightening performance", "frizz level", and "volume" under the following criteria: 5: Excellent 4: Good 3: Normal 2: Bad 1: Very poor

[0426] (Sensory evaluation) The treated hair swatches were rated for "ease of combing" and "ease of applying a hair iron" according to the following criteria:

[0427] - Easy to comb A trained person combed the hair swatches treated with each process and rated them for resistance to combing under the following criteria: 4. You can comb your hair with almost no friction 3: Low friction for easy combing 2: Combing is difficult and causes a lot of friction 1: Can't comb

[0428] - Ease of use with hair iron In step (iii) of each process, the iron's slip resistance upon application of the hair iron was evaluated by trained personnel under the following criteria: 4: Ironing is smooth without resistance 3: Ironing is easy to use as usual 2: Ironing takes effort and the tip of the iron gets caught 1: It is very difficult to iron evenly and the iron gets stuck frequently

[0429] The results are shown in Table 8 below.
