Description

[Technical Field]

[0001] The present invention relates to a hair styling composition and a hair styling method. [Background technology]

[0002] Hair styling compositions containing various ingredients are provided for various hair styling purposes. As an example of such a hair styling composition, a technology has been proposed (Patent Document 1) in which a predetermined amount of an (acrylates / beheneth methacrylate) copolymer or the like is blended into a hair styling agent to improve natural, wet-looking gloss and hair styling properties. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-194166 Summary of the Invention [Problem to be solved by the invention]

[0004] In hair styling compositions, solid oils (oils that are solid at 25°C) such as waxes and hydrocarbons that increase the adhesiveness between hair strands may be used in order to improve hair styling properties, such as forming hair bundles to lift the hair from the roots and providing manageable hair ends.

[0005] Among the above solid oils, microcrystalline wax is relatively excellent in terms of improving hair styling properties, but its incorporation can sometimes reduce the ease of spreading the hair styling composition on the palm when used. Such a reduction in the ease of spreading the hair styling composition can cause problems such as making it difficult to apply the hair styling composition evenly to the hair, making hair styling operations difficult, and requiring the use of a relatively large amount of the hair styling composition when styling the hair.

[0006] Furthermore, there is a demand for hair styling compositions with improved hair styling properties.

[0007] In view of the above problems, the present invention aims to improve the spreadability and hair styling properties of a hair styling composition containing a microcrystalline wax. [Means for solving the problem]

[0008] The present inventors have conducted extensive research into the above-mentioned problems and have found that a hair styling composition containing a microcrystalline wax and further containing a volatile hydrocarbon can provide a hair styling composition with improved spreadability and hair styling properties.The present inventors have also found that a hair styling composition containing a volatile hydrocarbon and a microcrystalline wax, when a certain amount or more of a non-volatile oil that is liquid at 25°C is added, tends to reduce the hair styling properties of the hair styling composition.

[0009] Therefore, the present inventors have found that a hair styling composition containing a volatile hydrocarbon and a microcrystalline wax can be provided with improved spreadability and hair styling properties if the amount of non-volatile oil that is liquid at 25°C is 7 mass% or less, or if no non-volatile liquid oil that is non-volatile at 25°C is blended.

[0010] That is, the hair styling composition of the present invention comprises: (A) Volatile hydrocarbons and (B) Microcrystalline wax are blended. (C) A hair styling composition in which the blend amount of non-volatile oil that is liquid at 25°C is 7 mass% or less, or (C) no non-volatile oil that is liquid at 25°C is blended.

[0011] The hair styling composition of the present invention preferably does not contain (D) cationic surfactant or contains (D) cationic surfactant in an amount of 0.5 mass % or less, since this provides better hair styling properties.

[0012] The hair styling composition of the present invention preferably contains at least isododecane as the volatile hydrocarbon (A), since this provides excellent durability of the styled state after styling.

[0013] The hair styling composition of the present invention preferably has an amount of (C) non-volatile oil that is liquid at 25°C of 5 mass% or less, or does not contain any (C) non-volatile oil that is liquid at 25°C, as this provides better hair styling properties.

[0014] The hair styling composition of the present invention is, for example, in the form of a cream.

[0015] The hair styling method of the present invention is a hair styling method using any of the above-mentioned hair styling compositions of the present invention. [Effects of the Invention]

[0016] According to the hair styling composition of the present invention, in a hair styling composition containing a microcrystalline wax, the spreadability and hair styling properties of the hair styling composition can be improved. Furthermore, the hair styling method of the present invention can provide a hair styling method using the hair styling composition of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be described below based on an embodiment of the present invention (hereinafter referred to as "the present embodiment").

[0023] Examples of the component (A) in the hair styling composition of this embodiment include branched volatile hydrocarbons and straight-chain volatile hydrocarbons. Examples of the branched volatile hydrocarbons include isododecane, light isoparaffin, and hydrocarbons having a kinematic viscosity of 20 mm 2 / s or less hydrogenated polyisobutene. Examples of the linear volatile hydrocarbons include dodecane, C9-12 alkanes, and C10-13 alkanes.

[0024] The hair styling composition of the present invention preferably contains at least isododecane as the volatile hydrocarbon (A), since this provides excellent durability of the styled state after styling.

[0025] The amount of component (A) in the hair styling composition of this embodiment is not particularly limited and can be set appropriately. The hair styling composition of this embodiment can improve spreadability, and from the viewpoint of further improving spreadability, the lower limit of the amount of component (A) to be blended is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, and the upper limit of the amount of component (A) to be blended is, for example, 20% by mass or less.

[0026] <(B) Microcrystalline wax> The hair styling composition of this embodiment contains a microcrystalline wax as component (B), which can impart excellent hair styling properties to the hair styling composition.

[0027] The amount of component (B) in the hair styling composition of this embodiment is not particularly limited and can be set appropriately. The hair styling composition of this embodiment can improve hair styling properties, and from the viewpoint of further improving the hair styling properties, the lower limit of the blending amount of component (B) is preferably 0.01% by mass or more, and more preferably 0.1% by mass or more. Furthermore, the hair styling composition of this embodiment can improve spreadability, and from the viewpoint of further improving the spreadability, the upper limit of the blending amount of component (B) is preferably 15% by mass or less, more preferably 13% by mass or less, and even more preferably 10% by mass or less.

[0028] The total amount of the component (A) and the component (B) in the hair styling composition of this embodiment, [(A) + (B)], is not particularly limited. The hair styling composition of this embodiment can improve hair styling properties, and from the viewpoint of further improving the hair styling properties, the lower limit of [(A) + (B)] is preferably 1 or more, more preferably 3 or more, and even more preferably 5 or more. The upper limit of [(A) + (B)] is preferably 35 or less, more preferably 30 or less, and even more preferably 25 or less, from the same viewpoint as the lower limit of [(A) + (B)].

[0029] The mass ratio [(B) / (A)] of the amount of component (B) to the amount of component (A) in the hair styling composition of this embodiment is not particularly limited.

[0064] (evaluation) The hair styling compositions of Examples 1 to 4 and Comparative Examples 1 to 4 prepared above were evaluated for "ease of spreading," "hair styling properties," and "lasting effect" according to the evaluation methods described below.

[0065] (Method for evaluating stretchability) 0.5 g of each hair styling composition of Examples 1 to 3 and Comparative Examples 1 to 4 was placed in the palm of one hand, and each hair styling composition was held between the palms of the other hand. The hair styling composition was rubbed five times back and forth between the palms of both hands, and the "ease of spreading" was evaluated using the ease of spreading as an index. The evaluation was made by a panel of four people who regularly evaluate hair styling compositions, and judged as either "good," "same," or "bad" according to the following evaluation criteria.

[0066] (Evaluation criteria for stretchability) ◯: Superior spreadability compared to the reference hair styling composition. Equivalent: Equivalent to the standard hair styling composition in terms of spreadability. ×: The spreadability is inferior to that of the standard hair styling composition.

[0067] (Method for evaluating hair styling properties) Using 1 g of each of the hair styling compositions of Examples 1 to 4 and Comparative Examples 1 to 4, the hair of an evaluation wig (a model wig manufactured by Regina Co., Ltd., with hair length adjusted to approximately 10 cm) was styled, and the "hair styling properties" were evaluated using the lift from the roots and the manageability of the hair ends as indicators. The evaluation was made by a panel of four people who routinely evaluate hair styling compositions, and judged as either "good," "same," or "bad" according to the following evaluation criteria.

[0068] (Evaluation criteria for hair styling) ○: Evaluated as having superior hair styling properties (lifting from the roots and tidying of the ends) compared to the standard hair styling composition. Equivalent: Evaluated as equivalent in hair styling properties (lift from the roots and manageability at the ends) compared to the standard hair styling composition. ×: Evaluated as being inferior in hair styling properties (lifting from the roots and manageability of the ends) compared to the standard hair styling composition.

[0069] (Method of evaluating sustainability) Using 0.5 g of each of the hair styling compositions of Examples 1 to 3 and Comparative Examples 1 to 4, the hair of an evaluation wig (the same as that used in the evaluation of hair styling properties) was styled by lifting it from the roots. The durability was then evaluated visually by comparing the difference between the state of hair lift from the roots immediately after styling and the state of hair lift from the roots three hours after styling. The evaluation was conducted by a panel of four people who regularly evaluate hair styling compositions, and judged as "good," "same," or "bad" according to the following evaluation criteria.

[0070] (Sustainability evaluation criteria) ○: Evaluated as having superior durability compared to the reference hair styling composition (compared to the reference hair styling composition, there is less difference between the state of hair lift from the roots immediately after styling and the state of hair lift from the roots 3 hours after styling). Equivalent: Evaluated as having the same durability as the reference hair styling composition (the difference between the amount of hair that stands up from the roots immediately after styling and the amount of hair that stands up from the roots 3 hours after styling is the same as the reference hair styling composition). ×: Evaluated as having inferior durability compared to the reference hair styling composition (compared to the reference hair styling composition, there is a large difference between the state of hair lift from the roots immediately after styling and the state of hair lift from the roots 3 hours after styling).

The hair styling composition of Comparative Example 1 was used as the evaluation standard.

[0073] [Table 1]

[0074] The results shown in Table 1 show that the hair styling compositions of Examples 1 and 2, which contain volatile hydrocarbons, are superior in terms of spreadability and hair styling properties compared to the hair styling composition of Comparative Example 1, which does not contain volatile hydrocarbons. Also, the hair styling composition of Comparative Example 2, which contains heavy liquid isoparaffin, which does not fall under the category of volatile hydrocarbons, is equivalent in spreadability to the hair styling composition of Comparative Example 1, which does not contain hydrocarbons, but is inferior in terms of hair styling properties.

[0075] (Evaluation results of Example 1 and Comparative Example 3) Table 2 below shows the ingredients and the evaluation results of the hair styling compositions of Example 1 and Comparative Example 3. The hair styling composition of Comparative Example 3 was used as the evaluation standard.

[0076] [Table 2]

[0077] The results shown in Table 2 show that the hair styling composition of Example 1, which contains microcrystalline wax, is superior in spreadability and hair styling properties compared to the hair styling composition of Comparative Example 3, which does not contain microcrystalline wax.

[0078] (Evaluation results of Examples 1 and 3 and Comparative Example 4) Table 3 below shows the ingredients and the evaluation results of the hair styling compositions of Examples 1 and 3 and Comparative Example 4. The hair styling composition of Comparative Example 4 was used as the evaluation standard.

[0079] [Table 3]

[0080] The results shown in Table 3 show that the hair styling compositions of Examples 1 and 3, which contain 7% or less of 2-ethylhexyl palmitate, a non-volatile oil that is liquid at 25°C, have similar spreadability but superior hair styling properties compared to the hair styling composition of Comparative Example 4, which contains 11% 2-ethylhexyl palmitate.

[0081] (Evaluation results of Examples 1 and 4) Table 4 below shows the ingredients and the evaluation results of the hair styling compositions of Examples 1 and 4. The hair styling composition of Example 1 was used as the evaluation standard.

[0082] [Table 4]

[0083] The results shown in Table 4 reveal that the hair styling composition of Example 4, which contained 0.1% by mass of the cationic surfactant stearyltrimethylammonium chloride, was evaluated as having the same spreadability as the hair styling composition of Example 1, which contained no cationic surfactant, but was inferior in the evaluations of hair styling properties and durability. Although not shown in a table, the hair styling composition of Example 4 was superior to the hair styling composition of Comparative Example 2 in spreadability.

[0084] (Evaluation results of Examples 1 and 2) Table 5 below shows the evaluation results of the hair styling compositions of Examples 1 and 2. The evaluation criteria were the hair styling composition of Comparative Example 2. The hair styling compositions of Examples 1 and 2 were the same as the hair styling compositions of Examples 1 and 2 in Table 1 above.

[0085] [Table 5]

[0086] The results shown in Table 5 show that the hair styling composition of Example 1 containing isododecane has the same spreadability and styling properties as the hair styling composition of Example 2 containing light isoparaffin, but is superior in the evaluation of durability.

[0087] (Evaluation results of Examples 1 and 3) Table 6 below shows the evaluation results of the hair styling compositions of Examples 1 and 3. The evaluation criteria were based on the hair styling composition of Example 3. The hair styling compositions of Examples 1 and 3 were the same as the hair styling compositions of Examples 1 and 3 in Table 3 above.

[0088] [Table 6]

[0089] The results shown in Table 6 show that the hair styling composition of Example 1, which contains 1% of non-volatile oil (2-ethylhexyl palmitate) that is liquid at 25°C, is evaluated as having the same spreadability as the hair styling composition of Example 3, which contains 5% of non-volatile oil (2-ethylhexyl palmitate) that is liquid at 25°C, but is superior in terms of styling properties and durability. Furthermore, when considering the evaluation results of hair styling properties and durability for Examples 1 and 3 and Comparative Example 4 in Table 6 and the above Table 3 together, it can be seen that the evaluation results of hair styling properties and durability tend to be better when the blending amount of non-volatile oil that is liquid at 25°C is less than 7 mass %.< / ph>
