Description

[0001] DESCRIPTION

[0002] TITLE OF INVENTION

[0003] COMPOSITION SUITABLE FOR KERATIN FIBERS

[0004] TECHNICAL FIELD

[0005] The present invention mainly relates to a composition which is suitable for reshaping, preferably straightening, keratin fibers such as hair.

[0006] BACKGROUND ART

[0007] Straightening keratin fibers such as hair by heating the keratin fibers with an iron is popular for making unruly keratin fibers manageable and making keratin fibers have less volume and look more desirable. Such a straightening method using a heating iron is convenient for quick styling, but the style lasts only a short period of time, e.g., until the next shampooing. A long-lasting straightening method is required for many consumers.

[0008] On the other hand, conventional permanent straightening methods using a reducing agent and an alkaline agent, as well as an oxidizing agent, with heating, can provide keratin fibers with a long-lasting style, but they have several drawbacks such as a long processing time, damage to the keratin fibers, and malodor.

[0009] WO 2014 / 131469 discloses a process for straightening keratin fibers by heating with an iron, without using reducing and oxidizing agents, wherein glyoxylic acid is used to straighten the keratin fibers.

[0010] US-A-2023 / 742 discloses a semi-permanent hair straightening composition including 15% to 20% by weight of glyoxylic acid and 0.1% to 5% by weight of levulinic acid.

[0011] DISCLOSURE OF INVENTION

[0012] There is still a need to improve the reshaping of keratin fibers based on treating the keratin fibers with glyoxylic acid or a derivative thereof.

[0013] An objective of the present invention is to provide a composition which is useful for reshaping keratin fibers such as hair, based on treating the keratin fibers with glyoxylic acid or a derivative thereof, which can provide the keratin fibers with longer-lasting reshaping effects.

[0035] BEST MODE FOR CARRYING OUT THE INVENTION

[0036] After diligent research, the inventors have found that it is possible to provide a composition which is useful for reshaping keratin fibers such as hair, based on treating the keratin fibers with glyoxylic acid or a derivative thereof, and which can provide the keratin fibers with longer-lasting reshaping effects.

[0037] Thus, the present invention mainly relates to a composition for keratin fibers, such as hair, comprising:

[0038] (a) at least one compound selected from the group consisting of glyoxylic acid, glyoxylic acid solvates, glyoxylic acid salts, glyoxylic acid esters, glyoxylic acid amides, and mixtures thereof;

[0039] (b) at least one compound, different from the (a) compound, selected from the group consisting of keto acids, salts thereof, and mixtures thereof; and

[0040] (c) at least one aminosilicone.

[0041] The present invention can improve reshaping keratin fibers such as hair, based on treating the keratin fibers with glyoxylic acid or a derivative thereof, by providing longer-lasting reshaping effects.

[0042] The reshaping of keratin fibers, such as hair, here encompasses straightening or curling the keratin fibers.

[0043] The present invention can provide keratin fibers such as hair with longer-lasting reshaping effects. Thus, the present invention can lengthen or prolong the reshaping effects for keratin fibers provided by using a composition including only glyoxylic acid or a derivative thereof. In particular, the present invention can further maintain the straightened or curled shape of keratin fibers, or can prevent or reduce loss of the straightened or curled shape of keratin fibers over time.

[0044] For example, if keratin fibers are originally wavy, the present invention can provide better prevention for the keratin fibers returning to the original wavy shape, after straightening the keratin fibers, in particular after shampooing.

[0045] The present invention can also provide keratin fibers with sufficient immediate reshaping effects. For example, the keratin fibers treated with the present invention to be straight can have less volume or less frizz due to the reduction of curls of the keratin fibers. The reshaping effects provided by the present invention can last a long time, for example, even after shampooing the keratin fibers. Thus, the present invention can also provide the shape of keratin fibers with good resistance to shampooing.

[0046] The present invention can provide keratin fibers with less damage as compared to conventional permanent reshaping processes, because the present invention does not need to use any reducing / oxidizing agents. Therefore, it can be easy to comb the keratin fibers treated by the present invention. Thus, the keratin fibers treated with the present invention can be easy to manage. Also, the keratin fibers treated by the present invention can be stronger than those treated by conventional permanent reshaping processes.

[0047] In addition, the present invention can use no or very little ammonia or thiol compound, and therefore, odor during the use of the present invention can be reduced as compared to the conventional processes which require the use of ammonia or a thiol compound. Also, the present invention can have good usability, for example, short processing time.

In this sense, the process according to the present invention can be a semi-permanent reshaping, preferably straightening, process.

[0312] It is preferable that the keratin fibers be cleaned before the step (i). This cleaning step may be performed by, for example, shampooing the keratin fibers, followed by rinsing off the keratin fibers. After rinsing off, the keratin fibers may be dried. It is preferable that the keratin fibers are wet just before the step (i).

[0313] In the step (i), the composition according to the present invention, which is explained above, is applied to keratin fibers such as hair. The application of the composition according to the present invention may be performed by any means, such as a brush or a comb.

[0314] The bath ratio of the applied composition according to the present invention to the keratin fibers may range from 0.1 to 10, more particularly from 0.5 to 5, and preferably between 0.3 and 2. The term "bath ratio" is intended to mean the weight ratio between the total weight of the applied composition and the total weight of the keratin fibers.

[0315] It may be possible that, after the application of the composition according to the present invention, the keratin fibers be left as they are for a certain amount of time; typically from 1 minute to 1 hour, preferably from 2 to 30 minutes, and more preferably from 3 to 10 minutes, if necessary, in order to let the composition penetrate into the keratin fibers.

[0316] After the step (i), the process according to the present invention may comprise the optional step (ii) of rinsing off the keratin fibers with or without drying the keratin fibers after being rinsed off.

[0317] Thus, if the step (ii) is present, the keratin fibers are rinsed off in order to remove the composition according to the present invention from the keratin fibers. The step of rinsing may be performed with water. It is preferable that the keratin fibers be dried after being rinsed off. The drying of the keratin fibers can be performed with a conventional drying means such as a hair dryer.

[0318] On the other hand, if the step (ii) is not present, the keratin fibers can be treated by the step (iii) after the step (i) without being rinsed off.

[0319] In the step (iii), the keratin fibers, which are preferably dry, are subjected to reshaping, preferably straightening, preferably at a temperature of more than 50°C, more preferably more than 100°C, and even more preferably more than 150°C, with a heater, such as a heating iron or a heating curler.

Thus, the reshaping means may be at least one heating iron and / or at least one heating curler and / or at least one heating comb and / or at least one heating dryer which can blow hot gas such as hot air. It may be preferable to use at least one heating iron and / or at least one heating curler.

[0322] As the heating iron, any conventional heating iron can be used. The heating iron can have at least one plate, preferably two plates, which can be heated by, for example, electric heating. The heated plate(s) can be applied onto the keratin fibers and moved along with the direction of the keratin fibers to straighten them.

[0323] It is preferable that the heating iron has two plates, and that keratin fibers are sandwiched between the two plates of the heating iron, in which at least one of the plates can be heated, and then the two plates are moved along the direction of the keratin fibers to straighten them.

[0324] It is preferable that the heating iron, in particular a part thereof contacting with keratin fibers, such as a heating plate or heating plates, has a temperature of more than 50°C and less than 250°C, more preferably more than 100°C and less than 240°C, and even more preferably more than 150°C and less than 230°C.

[0325] The step (iii) can be performed by one or more strokes of moving the heating iron along with the direction of keratin fibers. The step (iii) can be controlled by not only the temperature of the heating iron but also the number of strokes of the heating iron.

[0326] The heating time may depend on the temperature of the heating iron but also on the number of strokes of the heating iron. It may be, for example, from 1 second to 10 minutes, and preferably from a few seconds to 5 minutes.

[0327] As the heating curler, any conventional heating curler can be used. If the keratin fibers are rolled around a heating curler, this rolling-up may be performed on the entire length of the keratin fibers or, for example, on half the length of the keratin fibers. Depending on, for example, the desired hairstyle shape and amount of curls, the rolling-up may be performed with more or less thick locks.

[0328] It is preferable that the heating curler, in particular a part thereof contacting with keratin fibers, such as a heating rod and a heating cover, has a temperature of more than 50°C and less than 250°C, more preferably more than 100°C and less than 240°C, and even more preferably more than 150°C and less than 230°C.

[0329] The step (iii) can be performed by maintaining keratin fibers on a heating curler such that mechanical tension is applied on the keratin fibers. The step (iii) can be controlled by not only the temperature of the heating curler but also the strength of the mechanical tension.

[0330] The heating time may depend on the temperature of the heating curler but also on the strength of the mechanical tension. It may be, for example, from 1 second to 10 minutes, and preferably from a few seconds to 5 minutes.

[0331] If necessary, before the step (ii), mechanical tension may be applied to keratin fibers as explained above.

[0353] [Evaluations]

[0354] Each of the above compositions was used to straighten a hair swatch, and then the hair swatch was evaluated, in accordance with the following protocols.

[0355] 1) A hair swatch of Chinese black natural, slightly wavy hair, in a length of 27 cm was shampooed with the SLES shampoo, whose composition is shown in Table 2 below. The hair swatch was rinsed off thoroughly with tap water.

[0356] Table 2

[0357] 2) Each of the compositions according to Examples 1-4 and Comparative Example 1 was applied in an amount of 0.6 g onto the wet hair swatch.

[0358] 3) The hair swatch was left for 10 minutes at room temperature (25 °C).

[0359] 4) The hair swatch was rinsed off thoroughly with tap water.

[0360] 5) The hair swatch was blow-dried with a hair dryer (Nobby NB3100, TESCOM DENKI Co., Ltd, Japan) for about 90 seconds until dried.

[0361] 6) The hair swatch was subjected to straightening by 3 strokes with a hair straightening iron (ADST Premium DS2, Hakko Limited, Japan) at 180°C for 4 seconds / stroke.

[0362] 7) The straightening level of the hair swatch was evaluated visually just after step 6 (for straightening effect at TO) under the following criteria.

[0363] 5 : Very Good

[0364] 4: Good

[0365] 3: Fair

[0366] 2: Poor

[0367] 1 : Very Poor

[0368] The results are shown on the left side of in the row “Straightening Effects (T0 / Tlsh)” in Table 1.

[0369] 8) A photograph of the hair swatch was taken just after step 6, and the area (expressed by the number of pixels) of the hair swatch was determined with an open source, public domain software, Image J. The results are shown on the left side of in the row “Area (T0 / Tlsh)” in Table 1.

[0370] 9) The hair swatch was shampooed again with the SLES Shampoo, whose composition is shown in Table 2, rinsed off thoroughly with tap water, and blow-dried with the hair dryer (for about 90 seconds until dried). 10) The straightening level and area of the hair swatch were evaluated as above again (Tish).
