Description

[Technical Field]

[0001] The present invention relates to a cosmetic composition. [Background technology]

[0002] It is known that hair can be damaged and difficult to manage due to external factors in daily life, chemical treatments such as perms and coloring, etc. To resolve this condition, conditioning agents and styling agents are used to impart shine and smoothness to hair. However, these effects are often lost after one hair wash, and products that can maintain these effects are desired.

[0003] In recent years, in the field of cosmetics, techniques for forming hydrophobic films have been investigated as a method for imparting gloss, smooth feel, etc. to skin or hair. For example, Patent Document 1 discloses that a composition comprising a continuous aqueous phase and a discontinuous phase containing a plasticized MQ-type silicone resin and / or a derivative thereof, and / or a plasticized MT-type silicone resin and / or a derivative thereof, in which the discontinuous phase is emulsified in the aqueous phase, is useful as a hair care product for treating split ends. Patent Document 2 discloses a composition containing a silicone resin and a silicone rubber, wherein the mixture of the silicone resin and the silicone rubber has a softening point of more than 50°C and an elastic modulus of 106 Pa or less at ambient temperature, and discloses that when a formulation containing the composition is applied to hair, it imparts a smooth feel and strong shine.

[0004] Furthermore, one known hair dyeing technique is a temporary hair dye technique that uses a pigment or the like as a colorant and forms a film containing the colorant on the hair to dye the hair. For example, Patent Document 3 discloses a hair dye that contains 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, and at least a portion of the powder is a color pigment, which is easy to apply, does not cause secondary adhesion after application, and has good color retention.

[0006] However, since washing and drying hair takes time and effort, it is desirable that hair after conditioning or dyeing treatment is less susceptible to dirt and that the hair be dried quickly after washing. However, Patent Documents 1 to 3 do not mention these issues.

[0007] An object of the present invention is to provide a cosmetic composition that, when applied to keratinous materials such as skin or hair, can impart a dirt-preventing effect, a good feel to the touch, and a high drying speed, and that has excellent durability of these effects even after washing.

[0008] The present inventors discovered that the above-mentioned problems can be solved by a cosmetic composition that contains a silicone film-forming agent and a high molecular weight organopolysiloxane having a specified viscosity in a specified mass ratio, and that contains no more than a specified amount of water, and thus completed the present invention. The present invention relates to the following [1] to [7]. [1] A cosmetic composition comprising (A) a silicone film-forming agent and (B) a high-molecular-weight organopolysiloxane having a degree of polymerization of 2,600 or more and 4,500 or less, wherein the ratio of the mass of component (A) to the total mass of components (A) and (B) [(A) / ((A)+(B))] is 50% or more and 98% or less, and the water content is 10% or less by mass.

[5] A hair treatment method comprising the steps of applying the hair cosmetic composition described in [2] above to hair and then drying it. [6] A method for dyeing hair, comprising the steps of applying the hair dye composition according to [3] above to hair and then drying it. [7] A cosmetic kit comprising the following compositions (I) and (II): (I) (A) Composition containing a silicone film-forming agent (II)(B) A composition containing a high molecular weight organopolysiloxane having a degree of polymerization of 2,600 or more and 4,500 or less. [Effects of the Invention]

[0009] According to the present invention, a cosmetic composition can be provided that, when applied to keratinous materials such as skin or hair, can impart a dirt-repellent effect, a good feel to the touch, and a high drying rate, and that these effects are excellently sustained even after washing. Furthermore, when the cosmetic composition is used as a hair dye composition, the above effects can be imparted to hair, and color fading due to washing is minimal, resulting in good color sustainability. DETAILED DESCRIPTION OF THE INVENTION

[0010] [Definition] "Polymer," as used herein, means a compound corresponding to the repetition of one or more units (these units are derived from compounds known as monomers), which or these units are repeated at least twice, and preferably at least three times. "Hair" as used herein primarily refers to scalp hair. "Hydrophobic," as used herein, means that a substance has a solubility in water of less than 1% by weight at 25°C. "Film-forming," as used herein, means leaving a film on the substrate to which it is applied. "Volatile" as used herein means having a boiling point of 260°C or less at atmospheric pressure.

[0011] [Cosmetic composition] The cosmetic composition of the present invention comprises: (A) a silicone film former, and (B) a high-molecular-weight organopolysiloxane having a degree of polymerization of 2,600 or more and 4,500 or less; The cosmetic composition contains the above, wherein the ratio of the mass of component (A) to the total mass of components (A) and (B) [(A) / ((A)+(B))] is 50% or more and 98% or less, and the water content is 10% or less by mass. The cosmetic composition of the present invention has the above-mentioned constitution, and can impart a dirt-repellent effect, a good feel to the touch, and a high drying speed, and these effects are excellent in durability even after washing. Furthermore, when the cosmetic composition is used as a hair dye composition, the above-mentioned effects can be imparted to hair, and color fading due to washing is small, and color durability is also good.

[0012] The reason why the cosmetic composition of the present invention exhibits the above-mentioned effects is not clear, but is presumed to be as follows. The cosmetic composition of the present invention containing component (A) and component (B) can form a hydrophobic film by applying it to the surface of a keratinous material. Component (B) is thought to have the effect of imparting a pleasant feel to the surface of keratin materials, the effect of preventing the adhesion of dirt, and also to play a surface protection role. Furthermore, by having a viscosity within a specified range, component (B) is thought to be able to suppress stickiness and impart a pleasant feel. On the other hand, component (A) is a hydrophobic film-forming agent that maintains the strength and durability of the entire film that is formed, and is also thought to have a synergistic effect with component (B) that improves the durability of the various properties imparted to keratin substances. Furthermore, when functional powders described below are blended into the cosmetic composition, the functional powders can be retained in the film, thereby enhancing various functions and their durability.

[0013] By keeping the water content in the cosmetic composition at 10% by mass or less, it is possible to improve the mixability of component (A) and component (B) and form a uniform film on the surface of the keratin material. Furthermore, by keeping the ratio of the mass content of component (A) to the total mass content of components (A) and (B) that have the above-mentioned effects within a specified range, it is thought that the effect of preventing dirt adhesion can be imparted while maintaining a good feel and a high drying speed. Therefore, for example, when the cosmetic composition is a hair cosmetic composition, it is thought that when applied to hair, it can impart a dirt-preventing effect, a good feel, and a high drying rate, and that these effects can be maintained even after washing.When the cosmetic composition is a hair dye composition such as a temporary hair dye composition or a semi-permanent hair dye composition, the synergistic effect of component (A) and component (B) can impart the above effects to hair, and can also reduce color fading due to hair washing and improve color durability. The mechanism of action of the present invention is not limited to the above. Each component contained in the cosmetic composition of the present invention will be described below.

[Example]

[0084] The present invention will be described below with reference to examples, but the present invention is not limited to the scope of the examples. In the examples, various measurements and evaluations were carried out by the following methods.

[0085] <Preparing hair bundles for evaluation> A hair bundle of 100% human white hair (manufactured by Bealux Co., Ltd., 10 cm long, 1 g in mass) was washed with plain shampoo of the following composition, rinsed with warm water at 40°C, and thoroughly dried to prepare the hair bundle for evaluation. (Plain shampoo composition) Ingredients (mass %) Sodium Polyoxyethylene (2) Lauryl Ether Sulfate (*1) 15.5 Lauric acid diethanolamide (*2) 1.5 edetic acid tetrasodium salt 0.3 Sodium benzoate 1.43 Refined water residue Total 100.0 *1: 57.4% by mass of Emar 227 (manufactured by Kao Corporation, active ingredient 27% by mass) *2: Aminone L-02 (Kao Corporation)

[0086] <Difficulty in stain adhesion> 15 μL of each hair cosmetic composition was dropped onto a commercially available PET film (Toray Industries, Inc.; Lumirror Film T60-A4-100 μm), spread using a bar coater (AS ONE Corporation, No. 3), and allowed to dry naturally to form a coating film. The area where the coating film was formed was then cut into a 3 cm x 3 cm piece to prepare a test film. The mass of this film was designated F0 [g]. Zirconia beads (Nikkato Corporation, "YTZ Balls," Φ = 1 mm) were used as a model of physical soiling. 10.4 g of zirconia beads were placed in a balance dish (AS ONE Corporation, BD-2) and leveled, and the coating surface of a film cut into a 3 cm x 3 cm size was placed on top of the balance dish. Next, the balance dish was placed on top of the film, and a weight of 200 g, made from a standard bottle (AS ONE Corporation, No. 11) filled with tap water, was placed on top of the balance dish for 30 seconds, after which the weight was removed and the mass of the film with the beads attached (referred to as F1 [g]) was measured. The bead adhesion rate was calculated from the change in the film mass before and after contact with the beads using the following formula: The mass of beads required to cover 100% of the 3 cm x 3 cm test film area was 2.8367 g (average of two measurements). Bead adhesion rate [%] = (F1 - F0 [g]) ÷ (mass of beads that cover 100% of the test film area [g]) × 100 The above test was carried out twice, and the average values ​​are shown in Table 1. When the adhesion rate was 30% or less, it was difficult for the surface to become dirty, when it was 25% or less it was even more difficult, when it was 15% or less it was even more difficult, and when it was 5% or less it was even more difficult for the surface to become dirty.

[0087] <Feel when dry> 0.3 g of each hair cosmetic composition was applied to the hair bundle for evaluation, and then the hair was treated by applying warm air from a position 18 cm away for 2 minutes using a hair dryer (Hitachi Ltd. "P2-D250", set to HIGH) to dry the hair bundle. The feel of the treated hair bundle was evaluated by a specialist panel using the following criteria, and a total score of N=3 was calculated. A total score of 5 or less meant that the hair was very sticky and not smooth. A total score of 6 meant that the hair was smooth but sticky, and had a somewhat good feel. A total score of 7 or more meant a good feel, and a total score of 9 or more meant a better feel. 4: Almost no stickiness 3: Feels slightly sticky 2: Feeling sticky 1: Feels very sticky

[0088] <Feel of dry hair after washing 7 times> The hair bundle treated in the same manner as above was washed with the plain shampoo of the above composition, rinsed with warm water at 40°C, and dried, and this process was repeated seven times. After washing seven times and drying, the feel of the hair bundle was evaluated in the same manner as above.

[0089] <Drying speed (moisture content after rinsing)> 0.3 g of each hair cosmetic composition was applied to a hair bundle for evaluation, and then the hair was treated by applying hot air from a position 18 cm away to the hair bundle for 2 minutes using a hair dryer (Hitachi Ltd. "P2-D250", set to HIGH) to dry the hair. After treatment, the hair bundle was rinsed with warm water at approximately 40°C for 30 seconds, and after holding for 15 seconds, the moisture content W [%] was calculated using the following formula. Moisture content of treated hair bundle after rinsing W [%] = (a2 - a1) ÷ a0 × 100 a0: Weight of untreated hair bundle [g] a1: Weight of hair bundle after treatment [g] a2: Weight of treated hair bundle after rinsing [g] Furthermore, the ratio X [%] of the moisture content W of the treated hair bundle after rinsing to the moisture content (W0) of the untreated hair bundle after rinsing ((weight of untreated hair bundle after rinsing [g] - weight of untreated hair bundle a0 [g]) / weight of untreated hair bundle a0 [g]) was calculated using the following formula. X[%]=W÷W0×100 The smaller X is, the lower the moisture content after rinsing compared to untreated hair strands, and the faster the drying speed. If X is 80% or less, the drying speed will be perceived as faster. If X is 50% or less, the drying speed will be perceived as even faster, if it is 30% or less, the drying speed will be perceived as even faster, and if it is 15% or less, the drying speed will be perceived as even faster.

[0090] <Drying speed after 7 washes (moisture content after rinsing)> The hair bundle treated in the same manner as above was washed with the plain shampoo of the above composition and dried seven times. After seven washes, the drying speed of the hair bundle was evaluated in the same manner as above.

[0091] <Hair wash resistance (resistance to color fading due to washing)> 0.3 g of the hair cosmetic composition of Example 11 was applied to the hair bundle for evaluation, and then the hair was dried with a hair dryer to perform a hair treatment. The treated hair bundle was measured using a colorimeter (Konica Minolta, Inc., CR-400) in the CIE color system (L * ,a * ,b * After washing the hair seven times and drying it, the hair bundle was similarly measured with a color difference meter, and the color difference (ΔE * ) was calculated. * ,a * ,b * Measurements were taken at six different points on the hair bundle (two points in the center of each of the three equal areas that were obtained by dividing the hair bundle lengthwise), and the average value was calculated.
