Description

Technical Field

[0001] The present invention mainly relates to a composition suitable for reshaping keratin fibers such as hair, preferably straightening the hair.

Background Art

[0002] Straightening keratin fibers such as hair by heating with an iron is popular for making the keratin fibers, which are difficult to handle, easier to handle, reducing the volume of the keratin fibers, and making them look more desirable. Such a straightening method using a heating iron is convenient for immediate styling, but the style lasts only for a short time, for example, until the next hair wash. There is a need for a straightening method that lasts for a long time for many consumers.

[0003] On the other hand, conventional permanent straightening methods that use a reducing agent, an alkaline agent, and an oxidizing agent and heat can result in keratin fibers with a long-lasting style, but have several drawbacks such as a long processing time, damage to the keratin fibers, and a bad odor.

[0004] WO 2014 / 131469 discloses a method for straightening keratin fibers by heating with an iron without using a reducing agent and an oxidizing agent, and a method for straightening keratin fibers using glyoxylic acid.

[0005] US-A-2023 / 742 discloses a semi-permanent straightening composition containing 15% to 20% by mass of glyoxylic acid and 0.1% to 5% by mass of levulinic acid. The composition disclosed in the examples section also contains cetrimonium chloride.

Mode for Carrying Out the Invention

[0025] As a result of intensive studies, the present inventors have found a composition useful for reshaping keratin fibers such as hair based on treating keratin fibers with glyoxylic acid or a derivative thereof, which can provide a reshaping effect that lasts longer on the keratin fibers.

[0026] Therefore, the present invention mainly relates to a composition for keratin fibers such as hair, (a) at least one compound selected from the group consisting of glyoxylic acid, glyoxylic acid solvate, glyoxylate, glyoxylic acid ester, glyoxylic acid amide, and mixtures thereof, (b) at least one compound different from the (a) compound, selected from the group consisting of keto acids, their salts, and mixtures thereof, (c) at least one ester quat and relates to a composition comprising

[0027] The present invention can improve the reshaping of keratin fibers such as hair, which is based on treating keratin fibers with glyoxylic acid or its derivatives, by providing a reshaping effect that lasts for a longer time.

[0028] In this specification, the reshaping of keratin fibers such as hair includes straightening or curling of the keratin fibers.

[0029] The present invention can impart a reshaping effect that lasts for a longer time to keratin fibers such as hair. In particular, the present invention can further maintain the straight or curly shape of the keratin fibers, or can prevent or reduce the loss of the straight or curly shape of the keratin fibers over time.

[0030] For example, when the keratin fibers are originally wavy, the present invention can better prevent the keratin fibers from returning to their original wavy shape after straightening the keratin fibers, especially after washing the hair.

[0031] The present invention can also impart a sufficiently immediate reshaping effect to the keratin fibers. For example, the keratin fibers straightened by treatment according to the present invention can reduce volume or shrinkage of the hair because the curl of the keratin fibers is reduced. The reshaping effect brought about by the present invention can last for a long time even after washing the keratin fibers, for example. Therefore, the present invention can also provide a shape of keratin fibers that has good resistance to washing.

[0032] Since the present invention does not require the use of any reducing agent / oxidizing agent at all, it can provide keratin fibers with less damage compared to conventional permanent reshaping methods. Therefore, it may be easy to comb the keratin fibers treated according to the present invention with a comb. Therefore, the keratin fibers treated by the present invention can be easily handled. In addition, the keratin fibers treated by the present invention can be stronger than those treated by conventional permanent reshaping methods.

[0033] In addition, the present invention may not use or use very little ammonia or thiol compounds, and thus, compared with the conventional methods that require the use of ammonia or thiol compounds, the odor during the use of the present invention can be reduced. Further, the present invention has good usability, for example, a short treatment time is possible.

[0186] The method according to the present invention aims to reshape keratin fibers such as hair, preferably to straighten the hair, more preferably to keep the hair straight for a long time, and even more preferably to keep the hair straight even after several hair washings. In this sense, the method according to the present invention can be a semi-permanent reshaping method, preferably a hair straightening method.

[0187] It is preferable to wash the keratin fibers before step (i). This washing step can be carried out, for example, by shampooing the keratin fibers and then rinsing them. After rinsing, the keratin fibers may be dried. It is preferable that the keratin fibers are wet immediately before step (i).

[0188] In step (i), the composition according to the present invention described above is applied to the keratin fibers such as hair. The application of the composition according to the present invention can be carried out by any means such as a brush or a comb.

[0189] The bath ratio of the composition according to the present invention applied to the keratin fibers may range from 0.1 to 10, more specifically from 0.5 to 5, preferably from 0.3 to 2. The term "bath ratio" is intended to mean the mass ratio between the total mass of the applied composition and the total mass of the keratin fibers.

[0190] After application of the composition according to the invention, the keratin fibers can optionally be left as they are for a specific length of time, typically from 1 minute to 1 hour, preferably from 2 to 30 minutes, more preferably from 3 to 10 minutes, to allow the composition to penetrate into the keratin fibers.

[0191] After step (i), the method according to the invention may include an optional step (ii) of rinsing the keratin fibers and then drying or not drying the keratin fibers after rinsing.

[0192] Therefore, when step (ii) is present, the keratin fibers are rinsed to remove the composition according to the invention from the keratin fibers. The rinsing step may be carried out with water. The keratin fibers are preferably dried after rinsing. Drying of the keratin fibers can be carried out by conventional drying means such as a hair dryer.

[0193] On the other hand, when step (ii) is not present, after step (i), the keratin fibers can be treated by step (iii) without rinsing.

[0194] In step (iii), preferably the dried keratin fibers are reshaped, preferably straightened, using at least one device selected from the group consisting of an iron, a comb, a heating dryer, and combinations thereof, preferably using a combination of a comb and a heating dryer, preferably at a temperature above 50°C, more preferably above 100°C, even more preferably above 150°C. This temperature may be less than 250°C, preferably less than 240°C, more preferably less than 230°C. Thus, this temperature may be above 50°C and less than 250°C, preferably above 100°C and less than 240°C, more preferably above 150°C and less than 230°C.

[0195] Reforming can be carried out by applying some mechanical force, such as mechanical tension, to the keratin fibers.

For example, the mechanical force can be applied by at least one reforming means selected from the group consisting of at least one iron, at least one curler, at least one comb, and combinations thereof. Any conventional iron, curler, or comb may be used as the reforming means. A dryer capable of blowing a gas such as air can also be used as the reforming means.

[0196] The reforming means may comprise at least one heater. Therefore, the reforming means may be at least one heated iron and / or at least one heated curler and / or at least one heated comb and / or at least one heated dryer capable of blowing a high-temperature gas such as hot air. It may be preferable to use at least one heated iron and / or at least one heated curler.

[0197] Any conventional heated iron may be used as the heated iron. The heated iron can have, for example, at least one plate, preferably two plates, that can be heated by electric heat. The heated plate can be applied to the keratin fibers and moved along the direction of the keratin fibers to straighten the keratin fibers.

[0198] The heated iron preferably has two plates. The keratin fibers are sandwiched between the two plates of the heated iron, at least one of the plates can be heated, and then the two plates are moved along the direction of the keratin fibers, preferably causing the keratin fibers to be straightened.

[0199] A hair iron that contacts keratin fibers, particularly a part thereof (such as one or more heating plates), preferably has a temperature exceeding 50°C and less than 250°C, more preferably exceeding 100°C and less than 240°C, and even more preferably exceeding 150°C and less than 230°C.

[0200] Step (iii) can be carried out by one or more strokes of moving the hair iron along the direction of the keratin fibers. Step (iii) can be controlled not only by the temperature of the hair iron but also by the number of strokes of the hair iron.

[0201] The heating time can be determined by the temperature of the hair iron, but can also be determined by the number of strokes of the hair iron. For example, it may be from 1 second to 10 minutes, preferably from several seconds to 5 minutes.

[0202] As the heating curler, any conventional heating curler may be used. When winding the keratin fibers around the heating curler, this winding may be carried out with respect to the entire length of the keratin fibers, or, for example, with respect to half the length of the keratin fibers. For example, depending on the shape of the desired hairstyle and the amount of curl, the winding may be carried out in a more or less thick bundle.

[0203] A heating curler that contacts keratin fibers, particularly a part thereof (such as a heating rod and a heating cover), preferably has a temperature exceeding 50°C and less than 250°C, more preferably exceeding 100°C and less than 240°C, and even more preferably exceeding 150°C and less than 230°C.

[0204] Step (iii) can be carried out by maintaining the keratin fibers on the heating curler so that mechanical tension is applied to the keratin fibers. Step (iii) can be controlled not only by the temperature of the heating curler but also by the intensity of the mechanical tension.

[0205] The heating time can be determined by the temperature of the heating curler, but can also be determined by the strength of the mechanical tension. For example, it may be from 1 second to 10 minutes, preferably from several seconds to 5 minutes.

[0206] If necessary, before step (ii), as described above, mechanical tension may be applied to the keratin fibers.

Example

[0218] The present invention will be described in more detail by way of examples. However, these examples should not be construed as limiting the scope of the present invention.

[0219] (Example 1 and Comparative Examples 1 to 3) [Preparation] Each of the compositions according to Example 1 and Comparative Examples 1 to 3 was prepared by mixing the components shown in Table 1. The numerical values of the amounts of the components are all based on "mass%" of the raw materials.

[0220]

Table 1

[0221] [Evaluation] Using each of the above compositions, hair samples were straightened, and then the hair samples were evaluated according to the following protocol.

[0222] 1) A hair sample (length 27 cm) of slightly wavy black natural hair of Chinese people was washed with the SLES shampoo composition shown in Table 2 below. The hair sample was thoroughly rinsed with tap water.

[0223]

Table 2

[0224] 2) Each composition according to Example 1 and Comparative Examples 1 to 3 (each amount 1 g) was applied to the hair sample. 3) The hair sample was left at room temperature (25°C) for 10 minutes. 4) The hair sample was thoroughly rinsed with tap water. 5) The hair sample was dried with a hair dryer (Nobby NB3100, Tescom Denki Co., Ltd. Japan) for about 90 seconds until dry with hot air. 6) The hair sample was subjected to straightening by using a hair iron for straightening at 180°C (ADST Premium DS2, Hakko Limited, Japan) for 4 seconds per stroke and making 3 strokes. 7) The straightening level of the hair sample immediately after Step 6 (the straightening effect at T0) was visually evaluated according to the following criteria. 5: Extremely good 4: Good 3: Normal 2: Poor 1: Extremely poor The results are shown on the left side of the " / " in the row of "Straight hair effect (T0 / T1sh)" in Table 1. 8) Immediately after Step 6, a photograph of the hair sample was taken, and the area of the hair sample (expressed in number of pixels) was determined using the open-source public domain software Image J. The results are shown on the left side of the " / " in the row of "Area (T0 / T1sh)" in Table 1. 9) The hair sample was washed again with the SLS shampoo composition shown in Table 2, thoroughly rinsed with tap water, and dried with a hair dryer (for about 90 seconds until dry) using hot air. 10) The straight hair level and area of the hair sample were evaluated again as described above (T1sh). The results are shown on the right side of the " / " in the rows of "Straight hair effect (T0 / T1sh)" and "Area (T0 / T1sh)" in Table 1.

[0225] The evaluation results in Table 1 show that when esterquat is used together with a combination of glyoxylic acid and levulinic acid, the straight shape of the hair can be further maintained, or the increase in hair volume reflecting the curling or waving of the hair can be reduced, compared to using only the combination of glyoxylic acid and levulinic acid (Comparative Example 1), a combination of glyoxylic acid, levulinic acid, and a cationic surfactant other than esterquat (Comparative Example 2), or a combination of glyoxylic acid, levulinic acid, and a nonionic surfactant (Comparative Example 3).
