Description

[Technical Field]

[0001] This invention relates to a hair cosmetic composition. [Background technology]

[0002] In recent years, in the field of cosmetics, technologies for forming hydrophobic films on the surface of keratinous substances such as skin, hair, or eyelashes have been investigated in order to impart water resistance, makeup longevity, and other benefits. It is known that various silicone resins are used as polymers for forming hydrophobic films. For example, Patent Document 1 discloses a personal care composition for application to hair, skin, or nails, comprising a polysiloxane-grafted adhesive polymer, a volatile, water-insoluble solvent for the polymer, and a predetermined non-volatile drying aid, wherein the weight ratio of the adhesive polymer to the drying aid is less than or equal to a predetermined value, and which has the effect of reducing drying time.

[0003] Furthermore, as one of the hair dyeing techniques, there is a known technique for temporary hair dyes that uses pigments or the like as coloring agents to form a film containing the coloring agent on the hair to dye it. For example, Patent Document 2 discloses a hair dye that comprises a volatile oil, a water-repellent polymer that dissolves in the volatile oil, a powder, and a non-volatile oil that is compatible with the volatile oil, wherein at least a portion of the powder is a coloring pigment. This dye is easy to apply, does not cause secondary adhesion after application, and has good color retention. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-501934 [Patent Document 2] Japanese Patent Application Publication No. 10-265354 [Overview of the project] [Problems that the invention aims to solve]

[0005] Hair treated with hair cosmetic compositions using film-forming polymers has the problem that the hair strands become fixed together by the polymer, easily losing their natural texture and feel. In addition, from the perspective of reducing the burden of hair care, it is also important that the hair cosmetic composition is easy to spread over a wide area. Patent Document 1 uses a silicone resin as a drying aid to reduce drying time, achieving hair retention performance without leaving stickiness or stiffness. However, the hair tends to stick together easily, and it is insufficient in terms of providing a natural texture and feel. Furthermore, since hair is washed daily, there is a need for a product in which the treatment effect of the hair cosmetic composition is not lost after a single wash, and the effect is sustained. For example, the temporary hair dye described in Patent Document 2 requires that the color does not easily fade even after washing the hair after dyeing.

[0006] However, with conventional technology, it has been difficult to achieve a hair cosmetic composition that satisfies all of the above characteristics. The object of the present invention is to provide a hair cosmetic composition that, when applied to hair, is easy to spread over a wide area, makes hair less likely to stick together (easy to separate), provides good manageability, and has excellent wash durability.

[0007] The inventors have found that a hair cosmetic composition containing at least two predetermined film-forming polymers and a predetermined amount or less of water can solve the above problems, and have completed the present invention. The present invention relates to the following [1] to [5]. [1] Component (A): (R 1 )3SiO 1 / 2 M units and SiO are represented by 4 / 2 A film-forming polymer having Q units represented by the formula (wherein R 1 R represents a hydrocarbon group or hydroxyl group having 1 to 12 carbon atoms, which may be fluorine-substituted. 1 They may be the same or different from each other. Component (B): Film-forming polymers other than component (A), Ingredient (C): Water A hair cosmetic composition containing the same and having a content of component (C) of 80% by mass or less.

[4] A method for dyeing hair, comprising the step of applying the hair dye composition according to [2] above to the hair and then drying it. [5] A hair cosmetic kit comprising two or more compositions, A hair cosmetic kit in which the following components (A) to (C) are contained in the hair cosmetic composition obtained by mixing the compositions. Component (A): (R 1 )3SiO 1 / 2 A film-forming polymer having M units represented by and SiO 4 / 2 units represented by (where R 1 represents a hydrocarbon group or a hydroxy group having 1 to 12 carbon atoms which may be fluorine-substituted.

Advantages of the Invention

[0008] According to the present invention, when applied to hair, it can be easily spread over a wide range, and can impart hair fluffiness and good feel when passing through fingers, and can provide a hair cosmetic composition having excellent washing durability. Further, when the hair cosmetic composition is used as a hair dye composition, it can impart easy spreading, hair fluffiness, and good feel when passing through fingers, and also has little color fading by shampooing and good color persistence.

Modes for Carrying Out the Invention

[0009] [Definitions] As used herein, "polymer" means a compound consisting of a repetition of one or more units (these units are derived from compounds known as monomers). These units are repeated at least twice, preferably at least three times. In this specification, "hair" primarily refers to the hair on the head. As used herein, "hydrophobic" means that the solubility of a substance in water is less than 1% by mass at 25°C. As used herein, "film formation" means leaving a film on the substrate to which it is applied. As used herein, "volatile" means having a boiling point of 260°C or lower at normal pressure. "Ease of hair separation" refers to a state where the film formed on the surface of the hair does not easily adhere to each other, and the hairs do not easily stick together. On the other hand, "smoothness of hair" is a performance characteristic that stems from the physical properties and uniformity of the film formed on the surface of the hair.

[0010] [Hair cosmetic composition] The hair cosmetic composition of the present invention, Ingredient (A): (R 1 )3SiO 1 / 2 M units and SiO are represented by 4 / 2 A film-forming polymer having Q units represented by the formula (wherein R 1 R represents a hydrocarbon group or hydroxyl group having 1 to 12 carbon atoms, which may be fluorine-substituted. 1 They may be the same or different from each other. Component (B): Film-forming polymers other than component (A), Ingredient (C): Water It contains and the content of component (C) is 80% by mass or less. Hereinafter, "(R 1 )3SiO 1 / 2 M units and SiO are represented by 4 / 2 The unit represented as "Q unit" is also called the "MQ unit". The hair cosmetic composition of the present invention, having the above-described structure, when applied to hair, is easy to spread over a wide area, provides ease of hair separation and smoothness, and exhibits excellent wash durability. Furthermore, when this hair cosmetic composition is used as a hair dye composition, it provides ease of application, ease of hair separation and smoothness, as well as less color fading during washing and good color retention. Hereinafter, in this specification, the term "wash durability" will be used to refer to the fact that the hair treatment effect persists even after washing hair treated with a hair cosmetic composition, and, in the case of a hair dye composition, that there is little color fading due to washing.

[0011] The reason why the hair cosmetic composition of the present invention produces the above effects is not clear, but it is presumed to be as follows. The hair cosmetic composition of the present invention, which contains components (A) and (B) which are hydrophobic film-forming agents, can form a hydrophobic film when applied to the surface of hair. Component (A) contains rigid MQ units, allowing it to form a hard film. However, because component (A) has low toughness, the resulting film is brittle, and it tends not to easily separate the hair or provide a smooth feel to the hair after treatment. Since component (B) is generally tougher than component (A), it is believed that using component (B) in the hair cosmetic composition of the present invention makes it easier to form a uniform film even when water is present, and also enhances the flexibility of the formed film. As a result, it is believed that the ease of combing the hair after treatment and the ease with which hair bundles separate will be improved while maintaining washing durability. Furthermore, when a functional powder described later is incorporated into the hair cosmetic composition, the functional powder can be retained in the film, thereby enhancing various functions and their persistence. By including component (C) in the hair cosmetic composition, it is possible to suppress the adhesion of hydrophobic films formed on the hair surface, thereby improving the ease with which the hair separates. Furthermore, by keeping the amount of component (C) in the composition below a predetermined level, it becomes easier to spread the product on the hair, and the adhesion between hairs caused by excessive amounts of component (C) is suppressed, thus improving the ease with which the hair separates. However, the mechanism of action of the present invention is not limited to the above. The following describes each component contained in the hair cosmetic composition of the present invention.

[Examples]

[0077] The present invention will be described below with reference to examples, but the present invention is not limited to the scope of these examples. In these examples, various measurements and evaluations were performed by the following methods.

[0078] <Preparing hair bundles for evaluation> Human hair (100%) gray hair (manufactured by Beaulux Co., Ltd., 10 cm in length, 1 g in mass) was washed with a plain shampoo of the following composition, rinsed with 40°C warm water, and thoroughly dried to prepare the hair bundles for evaluation. (Composition of plain shampoo) Ingredients (mass %) Sodium polyoxyethylene(2) lauryl ether sulfate (*1) 15.5 Lauric acid diethanolamide (*2) 1.5 Tetrasodium edetate salt 0.3 Sodium benzoate 1.43 Refined water residue Total 100.0 *1: 57.4% by mass of Emal 227 (manufactured by Kao Corporation, active ingredient 27% by mass) *2: Aminone L-02 (manufactured by Kao Corporation)

[0079] <Ease of spreading> 0.05 to 0.2 ml of each hair cosmetic composition was dropped onto commercially available PET film (Toray Industries, Inc.; Lumirror Film T60-A4-100 μm) and spread using a bar coater (AS ONE Corporation, No. 60). After drying thoroughly at room temperature, the images were scanned using a multifunction printer (RICOH MP C5504) and saved as JPEG images. The area of ​​the spread portion of the hair cosmetic composition was calculated using the image processing software "Image J". The spread area per 0.1 ml was calculated from the amount of hair cosmetic composition dropped and the area of ​​the spread portion using the following formula. Coverage area per 0.1 ml [cm²] 2 ] = Area spread out [cm 2 ]÷Dropped amount [ml]×0.1 The above test was performed twice, and the average values ​​are shown in the table. The area spread per 0.1 ml was 9 cm². 2 If the measurement was less than 9cm, it was considered a failure. 2 If it is above this size, it will be easier to spread, 12cm 2 The above makes it easier to spread, 20cm 2The above makes it even easier to spread.

[0080] <How easily hair strands separate> 0.15 g of each hair cosmetic composition was applied to the evaluation hair bundles, and then the hair was dried with a hairdryer to perform the hair treatment. The dried hair bundles were scanned using a multifunction printer (RICOH MP C5504) to create JPEG images, and the width of the section 5.7 cm from the tip was calculated using the image processing software "Image J". Hair bundles with a width of 150mm or more tend to separate easily, those with a width of 165mm or more are more prone to separation, and those with a width of 200mm or more are even more prone to separation. Hair bundles with a width of less than 150mm were deemed unacceptable.

[0081] <Smoothness of the fingers> 0.15 g of each hair cosmetic composition was applied to the hair bundles used for evaluation. Then, a hair dryer (Hitachi P2-D250, set to HIGH) was used to dry the hair bundles for 2 minutes from a distance of 18 cm, thereby performing the hair treatment. The feel of the treated hair bundles was evaluated by a panel of experts according to the following criteria, and the average score for N=2 was calculated. 5: I find it very smooth to the touch. 4: It feels smooth to the touch. 3: I feel it's slightly smooth to the touch. 2: I feel it's slightly less smooth to the touch. 1: I feel like it doesn't go through my fingers well. If the average score for N=2 is less than 2, the fingers feel that the material doesn't glide smoothly and the feel is poor (fail). If the average score is between 2 and 3, there is a slight creaking sensation, but the fingers don't glide smoothly and the feel is fairly good. If the average score is between 3 and 4, the feel is good, and if it is 4 or higher, the feel is even better.

[0082] <Washing durability> For the hair cosmetic compositions of Examples 1-12 and Comparative Examples 1-2, 0.07 g of 15% by mass carbon black dispersion was added to 2 g of each example's hair cosmetic composition and uniformly mixed to prepare the evaluation composition, so that the formed film could be visually confirmed. The hair cosmetic composition of Example 13 was used as is for evaluation. 0.15 g of the evaluation composition was applied to the evaluation hair bundle, and then the hair treatment was performed by applying hot air from a position 18 cm away from the hair bundle for 2 minutes using a hair dryer (Hitachi P2-D250, set to HIGH). After processing, the hair bundles were color-coded using a colorimeter (Konica Minolta, Inc., "CR-400") to determine the CIE color system (L * ,a * ,b * After measuring the color using a colorimeter, the hair strands were washed with 40°C warm water using a plain shampoo of the above composition, and the drying process was repeated three times. After washing the hair three times and drying, the hair strands were similarly measured with a colorimeter, and the ΔE persistence rate [%] after three washes was calculated according to the following formula. * ,a * ,b * Measurements were taken at six different points on the hair strand (two points in the center of each of the three equal regions obtained by dividing the hair strand lengthwise), and the average value was calculated.

Furthermore, if the ΔE retention rate is >60%, it is even better; if it is >70%, it is even better; and if it is >90%, it is even better. If the ΔE retention rate is ≤50%, it is considered a failure.
