Abstract
Description
Title of the invention: METHOD FOR TREATING KERATINOUS FIBERS Technical field
[0001] The present invention mainly relates to a method of treating, preferably reshaping, and more preferably smoothing, keratinous fibers such as hair. STATE OF THE ART
[0002] Reshaping keratinous fibers such as hair by heating the keratinous fibers with an iron is common, making unruly keratinous fibers manageable and reducing the volume and improving the appearance of the keratinous fibers. Although such a reshaping method using a heating iron is convenient for quick styling, it is not easy to achieve a sufficient reshaping effect.
[0003] On the other hand, conventional permanent reshaping methods using a reducing agent and an alkaline agent, as well as an oxidizing agent, with heating, can provide keratinous fibers with an improved reshaping effect, but they have several disadvantages such as a long processing time, damage to the keratinous fibers and bad odor.

[0005] For example, JP-A-2020-066575 discloses a method of treating hair comprising:
[0006] an acid treatment consisting of applying to the hair a first acid hair composition containing an acid and / or a salt thereof;
[0007] a washing treatment consisting of washing the hair;
[0008] a silicone treatment consisting of applying a second com to the hair capillary position which is a liquid containing silicone;
[0009] a drying treatment consisting of drying the hair; and
[0010] a heat treatment consisting of placing the hair in contact with a heating element having a predefined temperature of at least 100°C.
[0011] Furthermore, US-A-2012-312317 discloses a method for semi-permanent hair straightening, comprising: a. the application of a solution comprising an alpha-keto acid serving as a buffering agent; b. keeping the solution in contact with the hair for 15 to 120 minutes; c. drying the hair, and d. straightening hair with a hair straightener at a temperature of approximately 200 + / - 50 °C.
[0012] Furthermore, JP-A-2019-123701 discloses a method of treating hair comprising: 1. a step of applying a hair treatment agent to the hair, containing (a) 13-30% by mass levulinic acid and (b) 1-2% by mass glyoxylic acid, the total content of levulinic acid and glyoxylic acid being 15% by mass or more and the pH being 1.5-3.0; 2. a step of leaving the hair; 3. a step of washing the hair with water; and 4. a step of straightening the hair with a hair straightener or hair straightener, a brush and the like at a certain temperature simultaneously during or after drying the hair.

[0053] Hereinafter, the present invention will be described in detail.
[0054] [Process]
[0055] The present invention relates to a method of fitness, preferably of smoothing of keratinous fibers, preferably hair, comprising the steps of:

[0065] Step (i) consists of applying a composition A to the keratinous fibers. Composition A will be described in detail later.
[0066] The application of composition A can be carried out by any means, such as a brush and a comb.
[0067] The bath ratio of composition A applied to the keratinous fibers can range from 0.1 to 10, more particularly from 0.5 to 5, and is preferably between 0.3 and 2. The term "bath ratio" is intended to designate the weight ratio between the total weight of the composition applied and the total weight of the keratinous fibers.
[0068] The amount of composition A applied to the keratinous fibers is not particularly limited, but generally ranges from 0.1 g to 1 g relative to 1 g of the keratinous fibers.
[0069] In one embodiment of the present invention, the keratinous fibers are cleaned before step (i). This cleaning step may be carried out, for example, by shampooing the keratinous fibers and then rinsing the keratinous fibers. After rinsing, the keratinous fibers may be dried. It is preferable that the keratinous fibers are wet just before step (i). The cleaning step is preferably performed once before the method of the present invention is carried out.

[0074] The bath ratio of the composition applied to the keratinous fibers may range from 0.1 to 10, more particularly from 0.5 to 5, and is preferably between 0.3 and 2, respectively. The term "bath ratio" is intended to designate the weight ratio between the total weight of the composition applied and the total weight of the keratinous fibers.
[0075] The amount of composition B applied to the keratinous fibers is not particularly limited, but generally ranges from 0.1 g to 1 g relative to 1 g of the keratinous fibers.
[0076] In one embodiment of the present invention, the keratinous fibers are cleaned before step (ii). This cleaning step may be carried out, for example, by shampooing the keratinous fibers and then rinsing the keratinous fibers. After rinsing, the keratinous fibers may be dried. It is preferable that the keratinous fibers are wet just before step (ii).
[0077] It may be possible, after the application of composition B, to leave the keratinous fibers as they are for a certain period 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, if necessary, in order to allow composition A to penetrate into the keratinous fibers.
[0078] Composition B may or may not be rinsed from the keratinous fibers after step (ii). In one embodiment of the present invention, the keratinous fibers are rinsed with water to rinse the applied composition B from the keratinous fibers after step (ii).
[0079] In a preferred embodiment, there is no cleaning step between steps (i) and (ii).
[0080] In one embodiment of the present invention, the method comprises step (i) and then step (ii) in that order. For this embodiment, it is preferable that there is no rinsing step between step (i) and step (ii).
[0081] In one embodiment of the present invention, the method comprises step (ii) and then step (i) in that order. For this embodiment, it is preferable that there is a rinsing step between step (ii) and step (i).
[0082] In another preferred embodiment, the method comprises step (i) then step (ii) then step (i) in that order. For this embodiment, it is preferable that there is no rinsing step between step (i) and step (ii), and that there is a rinsing step between step (ii) and step (i). {Step (iii)}
[0083] Step (iii) is an optional step. Step (iii) consists of heating the keratinous fibers to a temperature of more than 50°C, preferably more than 100°C, and more preferably more than 150°C. Step (iii) can be carried out once both steps (i) and (ii) are completed.
[0084] In one embodiment, the keratinous fibers are dried just before step (iii). The drying of the keratinous fibers can be carried out with a conventional drying means such as a hair dryer.
[0085] In step (iii), the keratinous fibers, which are preferably dry, are heated to a temperature of more than 50°C, preferably more than 100°C, and more preferably more than 150°C, with a heating element, preferably a heating iron or a heating curler. This temperature may be less than 250°C, preferably less than 240°C, and more preferably less than 230°C. Thus, this temperature may be more than 50°C and less than 250°C, preferably more than 100°C and less than 240°C, and more preferably more than 150°C and less than 230°C.
[0086] Heating may be accomplished by conventional means, such as the application of a heating iron or curler, or a hair dryer.
[0087] In addition, the reshaping may be performed by providing the keratinous fibers with any mechanical force such as mechanical tension. The mechanical force may be applied to the keratinous fibers by any reshaping means to deform the keratinous fibers into a desired shape. For example, the mechanical power may be provided by at least one reshaping means selected from the group consisting of at least one iron, at least one curler, and a combination thereof. Any conventional iron or curler may be used as the reshaping means.
[0088] The reshaping means may comprise at least one heating element. Thus, the reshaping means may be at least one heating iron and / or at least one heating curler. By reshaping the keratinous fibers, the keratinous fibers- keratinous fibers can be straightened or curled. Thus, the method according to the present invention can be for straightening or curling keratinous fibers, such as hair.
[0089] As a heating iron, any conventional heating iron can be used. The heating iron may have at least one plate, preferably two plates, which can be heated, for example, by electrical heating. The heated plate(s) can be applied to the keratinous fibers and moved in the direction of the keratinous fibers to smooth them.
[0090] It is preferable that the heating iron has two plates, and that the keratinous 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 in the direction of the keratinous fibers to straighten them.
[0091] It is preferable that the heating iron, in particular a portion thereof in contact with keratinous 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.
[0092] Step (iii) may be carried out by one or more passes of the heating iron in the direction of the keratinous fibers. Step (iii) may be controlled not only by the temperature of the heating iron but also by the number of passes of the heating iron.
[0093] The heating time may depend on the temperature of the heating iron, but also on the number of passes of the heating iron. It may be, for example, from 1 second to 10 minutes, and preferably from a few seconds to 5 minutes.
[0094] As a heating curler, any conventional heating curler can be used. If the keratin fibers are wound around a heating curler, this winding can be carried out over the entire length of the keratin fibers or, for example, over half the length of the keratin fibers. Depending, for example, on the desired hairstyle shape and the amount of curls, the winding can be carried out with more or less thick strands.
[0095] It is preferable that the heating rod, in particular a portion thereof in contact with keratinous fibers, such as a heating rod and a heating helmet, 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.
[0096] Step (iii) may be carried out by holding the keratinous fibers on a heating coil so that mechanical tension is applied to the keratinous fibers. Step (iii) may be controlled not only by the temperature of the heating coil but also by the intensity of the mechanical tension.
[0097] The heating time may depend on the temperature of the heating element, but also the intensity of the mechanical tension. It can be, for example, from 1 second to 10 minutes, and preferably from a few seconds to 5 minutes.
[0098] If necessary, before step (iii), mechanical tension can be applied to the keratinous fibers as explained above.

[0124] According to one embodiment, the silicone (a), preferably the silicone oil, may be chosen from non-volatile polydialkylsiloxanes, for example, polydimethylsiloxanes having trimethylsilyl end groups known under the trade name dimethicones.
[0125] Preferred silicones (c) according to the present invention may be polydimethylsiloxanes having trimethylsilyl end groups, such as oils having a viscosity at 25°C greater than 1,000,000 cSt (mm2 / s), even more preferably a viscosity greater than 2,000,000 cSt, and even more particularly greater than 5,000,000 cSt, better still greater than 10,000,000 cSt and preferably less than 50,000,000 cSt, better still less than 30,000,000 cSt, still better still less than 15,000,000 cSt.

[0499] Composition A was applied in an amount of 0.2 g to the strand of wet hair as a pretreatment (Step (i)).
[0500] Then, without rinsing, composition B was applied in an amount of 0.6 g to the lock of hair (Step (ii)).
[0501] The hair strand was left for 10 minutes at room temperature (25°C). The hair strand was then thoroughly rinsed with tap water and then dried with a hair dryer until the hair strand was dry.
[0502] The hair strand was straightened in 3 passes with a straightening iron (ADST Premium DS2, Hakko Limited, Japan) at 180°C, 4 seconds / pass (Step (iii)). Comparative example 1
[0503] The hair strand, which was the same as that used in Example 1, was washed with 0.5 g of an ordinary shampoo according to Example 1. The formulation of the ordinary shampoo was the same as that used in Example 1. Then, no treatment was applied to the hair strand according to Comparative Example 1. Thus, none of steps (i) to (iii) were carried out in this method. Comparative example 2
[0504] A sample according to Comparative Example 2 was prepared using 0.5 g of an ordinary shampoo according to Example 1, and then the hair strand was dried with a hair dryer until the hair strand was dried. Then, the hair strand was subjected to straightening without any treatment with the hair straightener. The straightening method was the same as that of Example 1. Thus, only step (iii) was conducted in this method. Comparative example 3
[0505] A sample according to Comparative Example 3 was prepared in the same manner as Example 1, but no pretreatment with composition A was carried out. Thus, step (i) was not carried out in this process. Comparative example 4
[0506] A sample according to Comparative Example 4 was prepared in the same manner as Example 1, composition A' was used instead of composition A in the pretreatment step. Thus, step (i) of the present invention using the silicone(s) (a) and the vegetable oil(s) (b) was not carried out in this process. Example 2
[0507] A sample according to Example 2 was prepared in the same manner as Example 1, a strand of Chinese curly hair (type III) was used instead of the strand of Brazilian curly hair (type IV). Example 3

[0535] (Smoothing effect)
[0536] After each of the treated hair strands was kept at room temperature (25°C) for three hours, the smoothing level of the treated hair strand was visually evaluated based on three aspects of “smoothing performance”, “frizz level” and “volume” according to the following criteria.
[0537] 5: Excellent
[0538] 4: Good
[0539] 3: Correct
[0540] 2: Bad
[0541] 1: Very bad
[0542] (Sensory appreciation)
[0543] The treated hair strands were evaluated in terms of “ease of combing” and “ease of application of hair iron” according to the following criteria. - Easy to comb
[0544] The hair strand treated in each of the processes was combed by a trained person and the combing resistance was evaluated according to the following criteria.
[0545] 4: Combing can be done with almost no feeling of friction
[0546] 3: Combing is easy with low friction
[0547] 2: Combing requires effort, friction is very high
[0548] 1: Impossible to comb - Ease of application of the hair iron
[0549] In step (iii) of each of the methods, the slip resistance of the iron in the hair iron application was evaluated by a trained person according to the following criteria.
[0550] 4: The passage of the iron is regular, without resistance
[0551] 3: The iron passage is easy, as usual
[0552] 2: Passing the iron requires effort, the iron gets stuck at the tips
[0553] 1: Passing the iron evenly is very hard, the iron gets stuck frequently
[0554] The results are shown in Table 8 below.
