The present invention relates to a cosmetic composition.
It is known that hair is damaged and difficult to handle by external factors in daily life, and chemical treatment such as perm and color. In order to solve such a situation, a conditioning agent or a styling agent is used to impart gloss or smoothness to hair. However, many of these effects are lost by one shampooing and by physical forces applied in daily life such as friction between hair and a pillow or the like during sleeping, and products capable of sustaining the effects are desired. Further, It is desired that a good feel can be imparted to hair in any daily life, i.e., in a dry state or a wet state. For example, Patent Literature 1 (JP 2015-515981 T) discloses that a composition containing a continuous aqueous phase, and a discontinuous phase that contains 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 haircare product for treating split ends.
Patent Literature 2 (JP 2016-503433 T) discloses a composition containing a silicone resin and a silicone rubber, in which a mixture of the silicone resin and the silicone rubber have a softening point higher than 50° C. and an elastic modulus of 106 Pa or less at an environmental temperature, and discloses that when a formulation containing the composition is applied to hair, it can impart a smooth feel and a strong gloss to the hair.
Regarding a cosmetic composition containing a colorant such as a pigment, a technique of using a film forming agent for the purpose of increasing durability after application and suppressing colorant transfer is investigated. For example, Patent Literature 3 (JP 2000-501074 T) discloses a cosmetic composition containing a mixture prepared by mixing an organosiloxane resin and a fluid diorganopolysiloxane polymer in a specific ratio, and a volatile carrier, and discloses formation of a thin durable film having resistance to transfer in contact with a substance such as cloth or a towel.
As one hair dyeing technique, there is known a temporary hair dye technique of using a pigment as a colorant and forming a film that contains the colorant on hair for dyeing the hair. The hair dye can dye hair in a simple manner with few damages to hair, but some may easily discolor by shampooing, or owing to poor rubfastness after hair dyeing, the color film may peel off by friction given thereto to cause secondary adhesion to clothes and pillows.
Regarding this, for example, Patent Literature 4 (JP H10-265354 A) discloses that a hair dye containing a volatile oil, a water-repellent polymer such as silicone resin and a high-molecular-weight organopolysiloxane dissolving in the volatile oil, a powder, and a nonvolatile oil compatible with the volatile oil, in which at least a part of the powder is a color pigment, is applicable in a simple manner and secures good color duration not causing secondary adhesion after application.

Having the above constitution, the cosmetic composition of the present invention is, when applied to a keratin substance such as skin or hair, able to impart a good feel thereto in any of a dry state or a wet state, excellent in durability to friction, and excellent in sustainability of these effect even after washing.

Patent Literature 4 refers to secondary adhesion of a hair dye, color sustainability and feel in use, but does not refer to improvement of feel of hair in a wet state.
Among such hitherto-existing cosmetic compositions, there could not as yet be provided cosmetic compositions which, when applied to a keratin substance such as skin or hair, can impart a good feel in any of a dry state and a wet state, and are excellent in durability to friction, and excellent in sustainability of these effects even after washing.
An object of the present invention is to provide a cosmetic composition which, when applied to a keratin substance such as skin or hair, can impart thereto a good feel in any of a dry state and a wet state, and is excellent in durability to friction, and excellent in sustainability of these effects even after washing.
It is considered that the film formed on a keratin substance for solving the problems is required to have the following properties.
It is considered that, for imparting a good feel to a keratin substance, the film surface needs to be smooth, and for durability to friction, the film needs to be adhesive to a keratin substance and needs to have a film strength durable to the physical force during friction. Further, for securing durability to washing, it is considered that the film needs to be hydrophobic and to have a film strength durable to the physical force during washing.
Namely, for solving the problems with the present invention, it is considered that plural different properties that the film formed on a keratin substance is hydrophobic and that the film has a smooth surface, a high film strength and a high adhesiveness to a keratin substance must be satisfied all at the same time. Accordingly, another object of the present invention is to form a film on a keratin substance, which satisfies all the requirements that the film is hydrophobic and has a smooth surface, a high film strength and a high adhesiveness to a keratin substance.
The present inventor has found that a cosmetic composition containing a silicone film-forming agent, a high-molecular-weight organopolysiloxane, and an organopolysiloxane having a polyalkylene oxide moiety and a cationic group can solve the above-mentioned problems, and has completed the present invention.
According to the present invention, there can be provided a cosmetic composition which, when applied to a keratin substance such as skin or hair, can impart thereto a good feel in any of a dry state and a wet state, and is excellent in durability to friction, and excellent in sustainability of these effects even after washing. In the case where the cosmetic composition is used as a hair dye composition, it can impart a good feel to hair in any of a dry state and a wet state, and the color film peels little by friction after hair dyeing, and can suppress secondary adhesion to clothes and pillows. In addition, after shampooing, discoloration is low and color sustainability is good, and further, even after shampooing, a good feel retains and a secondary adhesion suppressing effect can also be sustained.
The reason why the cosmetic composition of the present invention exhibits the above-mentioned effects is, though not clear, presumed as follows.
The cosmetic composition containing the component (A), the component (B) and the component (C) of the present invention is, when applied to the surface of a keratin substance, able to form a hydrophobic film.
Preferably, the cosmetic composition containing the component (A), the component (B) and the component (C) is temporarily compatibilized or dispersed before use, and then applied to the surface of a keratin substance, whereby it is considered that the components could be in phase separation with time and a multilayered hydrophobic film having a concentration distribution of the components in the thickness direction could be formed on the surface of a keratin substance.
A specific multilayered structure is a multilayered structure having at least two layers having a layer containing the component (B) in the outermost surface of the film, and having a layer containing the component (C) on the interface side to the keratin substance, and is preferably a multilayered structure having at least three layers that further has a layer containing the component (A) between the layer containing the component (B) and the layer containing the component (C).
Here, the constituent layers may not be distinctly separated from each other. In the present specification, the “layer” in the multilayered structure may have a region which has a concentration distribution in the thickness direction of the film and in which at least one component of the components (A) to (C) is eccentrically located as a main component, and such region is referred to as “layer” herein. For example, “having a layer containing the component (B) in the outermost surface of the film” means that in the film, the component (B) is eccentrically located as a main component on the outermost surface side relative to the thickness direction of the film. The main component as referred to herein means a component having a highest concentration among the components (A) to (C). With that, it is considered that a high-molecular chain of a component mainly contained in the neighboring layer may mutually invade into the interlayer to form an interfacial phase having a thickness and having a continuously varying concentration.
In the case where the cosmetic composition of the present invention is applied to the surface of a keratin substance, the component (B) is considered to be eccentrically located in the outermost surface of the formed film and play a role in imparting a good feel to the surface of a keratin substance, and further play a function as a surface protective layer. The component (C) is considered to be eccentrically located on the side of the keratin substance, and is considered to firmly adsorb the formed film to the surface of the keratin substance to exhibit the film peeling preventing effect.
On the other hand, the component (A) is a hydrophobic film-forming agent, and is considered to exist in the layer containing the component (B) or the component (C) in the formed film, or to be eccentrically located in the intermediate part of the layer containing the component (B) and the component (C) in the formed film to thereby secure the strength and the durability of the entire formed film and to also exhibit the durability improving effect of various characteristics given to the keratin substance owing to the synergistic effect with the component (B) and the component (C).
In the case where a functional powder to be mentioned hereinunder is incorporated in the cosmetic composition, the functional powder can be kept in the film to enhance various functions and sustainability thereof.
Owing to the mechanism of the action mentioned above, it is considered that, in the case where the cosmetic composition is, for example, a hair cosmetic composition, because of synergistic effect of the film-forming performance of the component (A), the feel-imparting effect and the surface protective performance of the component (B) and the film peeling preventing performance of the component (C), when the composition is applied to hair, it can impart a good feel to hair in any of a dry state and a wet state, and can provide durability to friction and sustainability of these effects after washing.
In addition, it is also considered that, in the case where the cosmetic composition is a hair dye composition such as a temporary hair dye composition or a semi-permanent hair dye composition, it can be a hair dye composition capable of imparting a good feed to hair in any of a dry state and a wet state after hair dyeing, and capable of suppressing the colored film from peeling owing to friction after hair dyeing. Moreover, it is considered that the hair dye composition can secure good color retentiveness with little discoloration after shampooing, can secure a good feel even after shampooing and can secure a secondary adhesion preventing effect.
The mechanism of the action of the present invention is not limited to the above.

Hereinunder the present invention is described with reference to Examples, but the present invention is not restricted to the range of Examples. In these Examples, various measurements and evaluations were carried out according to the following methods.
Human gray hair (100%) bundles (by Beaulax Co., Ltd., length 10 cm, mass 1 g) were shampooed with the following model shampoo having a formulation mentioned below, then rinsed with warm water at 40° C., and fully dried to prepare hair bundles for evaluation.
The hair cosmetic composition of each example was uniformly mixed, and 0.3 g thereof was applied to the hair bundle for evaluation, and then this was dried for 30 seconds with a drier (“P2-D250” by Hitachi Limited, setting HIGH) by applying hot air from a position separated by 18 cm from the hair bundle, and was thereafter further dried with hot air for 30 seconds while kept combed for hair treatment. After dried, expert panelists organoleptically evaluated the feel of the treated hair bundles according to the following criteria, and a total point of N = 3 was calculated. A total point of 6 or more means an acceptable feel, 9 or more means a good feel and 12 or more means a better feel.
The hair cosmetic composition of each example was uniformly mixed, and 0.3 g thereof was applied to the hair bundle for evaluation, and then this was dried for 30 seconds with a drier (“P2-D250” by Hitachi Limited, setting HIGH) by applying hot air from a position separated by 18 cm from the hair bundle, and was thereafter further dried with hot air for 30 seconds while kept combed for hair treatment. After treated, the hair bundles were shampooed with the model shampoo having a formulation mentioned above, then rinsed with warm water at 40° C., and expert panelists organoleptically evaluated the feel of the resultant hair bundles according to the following criteria. A point 2 or more means a good feel, and 3 or more means a better feel.
The hair bundles treated in the same manner as in the above “feel in dry state” were shampooed with the model shampoo having a formulation as above, rinsed with warm water at 40° C. and dried. The process was repeated 7 times. After shampooing 7 times, the feel of the dried hair bundles was organoleptically evaluated in the same manner as above.
Regarding the hair cosmetic composition of Examples 1 to 20 and Comparative Example 1, in order that the formed film could be visually confirmed, 0.15 g of 15 mass% carbon black dispersion was added to 6 g of the hair cosmetic composition of each example, and uniformly mixed to prepare compositions for evaluation.
Regarding the hair cosmetic composition of Examples 21 to 25 containing a pigment as the component (D), the ingredients shown in the table were uniformly mixed to prepare hair cosmetic compositions for evaluation.
0.3 g of the composition was applied to the hair bundle for evaluation, and then this was dried for 30 seconds with a drier (“P2-D250” by Hitachi Limited, setting HIGH) by applying hot air from a position separated by 18 cm from the hair bundle, and was thereafter further dried with hot air for 30 seconds while kept combed for hair treatment.
The treated hair bundle was analyzed with a color difference meter (CR-400 by Konica Minolta, Inc.) in a CIE color system (L*,a*,b*). Then, this was shampooed with the model shampoo having a formulation mentioned above, rinsed with warm water at 40° C. and dried. The process was repeated 7 times. After shampooing 7 times, the dried hair bundle was analyzed with the color difference meter in the same manner as above, and according to the following equation, a color difference (ΔE*) from the hair bundle before shampooing was calculated. L*, a* and b* were measured at different 6 points on the hair bundle (each at 2 central points of each region obtained by equally dividing the hair bundle into three in the length direction), and the found data were averaged to give an average value.
wherein:
Regarding the hair cosmetic composition of Examples 1 to 20 and Comparative Example 1, in order that the formed film could be visually confirmed, 0.15 g of 15 mass% carbon black dispersion was added to 6 g of the hair cosmetic composition of each example, and uniformly mixed to prepare compositions for evaluation.
Regarding the hair cosmetic composition of Examples 21 to 25 containing a pigment as the component (D), the ingredients shown in the table were uniformly mixed to prepare hair cosmetic compositions for evaluation.
0.3 g of the composition was applied to the hair bundle for evaluation, and then this was dried for 30 seconds with a drier (“P2-D250” by Hitachi Limited, setting HIGH) by applying hot air from a position separated by 18 cm from the hair bundle, and was thereafter further dried with hot air for 30 seconds while kept combed for hair treatment.
Next, a qualitative filter disc No. 2 (150 mmΦ, by ADVANTEC Corporation) was folded half, and the treated hair bundle was sandwiched therein. While a weight of 600 g was put on this, the hair bundle was pulled out in about 1 second, and this operation was repeated for a total of 3 times.
After used, the filter disc was scanned, and using an image processing software “Image J”, the area onto which carbon black or pigment had adhered was determined, and the adhesion ratio {(adhesion area) ÷ (filter area) × 100} (%) was calculated and shown in the table. A smaller value of adhesion ratio means that color transfer to the filter paper is smaller and the tested sample has better rubfastness. An adhesion ratio of 1.70 (%) or less means good, 0.95 (%) or less means better, and 0.60 (%) or less means further better.
The hair bundle treated in the same manner as in the above “rubfastness (difficulty of color transfer)” was shampooed with the model shampoo having a formation as above, rinsed with warm water at 40° C. and dried. The process was repeated for a total of 7 times. The hair bundle shampooed and dried 7 times was evaluated for the rubfastness according to the same method as above.
Examples 1 to 20, Comparative Example 1 (preparation and evaluation of hair cosmetic composition)
Ingredients shown in Tables 1 to 6 were blended according to the formulation described in each Table, and then mixed until uniform to prepare hair cosmetic compositions. The resultant hair cosmetic compositions were evaluated according to the above-mentioned methods. The results are shown in Tables 1 to 6.
The blending amount (mass%) shown in Tables is an active ingredient amount.
Ingredients shown in the tables are as described below.
The degree of polymerization (P) of the components *7 to *11 can be calculated as follows. From the viscosity (η), the molecular weight (M) is derived according to the above-mentioned formula (4). Since the molecular weight of the base unit of dimethylpolysiloxane is 74, the degree of polymerization (P) is calculated according to the following formula (5).
As in Tables 1 to 6, when the cosmetic composition of the present invention was applied to keratin substances, a good feel was given in any of a dry state and a wet state, the composition was excellent in durability to friction, and even after washing 7 times, these effects were sustained.
The film formed of the hair cosmetic composition of Example 1 is composed of trimethylsiloxysilicate of the component (A), high-molecular-weight organopolysiloxane of the component (B) and PEG/amodimethicone copolymer of the component (C).
As in
The elastic modulus of the film in dry of the component (A) is higher than that of the components (B) and (C), from which it is presumed that the component (A) is eccentrically located in the intermediate part of the film.
On the other hand, the hair cosmetic composition of Example 1 gives a good feel in any of a dry state and a wet state, from which it is presumed that the component (B) having surface smoothness is eccentrically located in the outermost surface of the film. In addition, from durability to friction and durability to washing, it is presumed that the component (C) having high adhesiveness to a keratin substance is eccentrically located on the keratin substance side.
Further, since the elastic modulus in the film intermediate part of the elastic modulus analyzing image gently varies toward the film thickness direction, it is presumed that the layers containing the respective components are not clearly separated from each other and that in the interlayer therebetween high-molecular chains of different components mutually invade thereinto to form an interface phase having a thickness where the concentration continuously varies.
As in the above, it is confirmed that, after applied to the surface of a keratin substance, the hair cosmetic composition of Example 1 undergoes phase separations of the components (A) to (C) to form a multilayered structure on the surface of the keratin substance.
The hair cosmetic composition of Example 1 was uniformly mixed, and 0.3 g thereof was applied to the hair bundle for evaluation, and then dried with a drier for hair treatment. The treated hair bundle was immersed in a liquid photocurable resin composition (Aronix LCR D-800, by Toagosei Co., Ltd.) and irradiated with UV rays for 1 minute (LED fiber light source (LUXSPOT II), by JEOL Corporation), and thus every hair was buried in the resin one by one. The resin in which the treated hair had been buried was fixed on a 12 mmΦ-AFM sample stand (AFM specimen disc, by TED PELLA Corporation) using an adhesive. Using a single-edged trimming razor (T568, by GEM Corporation), the test sample face was exposed out, and using an ultramicrotome (EM UC7i, by Hitachi High Tech Corporation), the test sample face was scraped out.
For the measurement, an atomic force microscope (MFP-3D, by Oxford Instrument Corporation) was used in an AMFM mode. As the cantilever, AC-160TS (spring constant 29.4 N/m, by Olympus Corporation) was used. The measurement environment was temperature of 25.5° C. and humidity of 34 to 39%.
Ingredients shown in Table 7 were blended according to the formulation described in the Table, and then mixed until uniform to prepare hair dye compositions. The resultant hair dye compositions were evaluated according to the above-mentioned methods. The results are shown in Table 7.
The blending amount (mass%) shown in the Table is an active ingredient amount.
As in Table 7, when the hair dye composition of the present invention was applied to hair, a good feel was given in any of a dry state and a wet state, the composition was excellent in durability to friction, and even after washing 7 times, these effects were sustained.
Ingredients shown in Table 8 were blended according to the formulation described in the Table, and then mixed until uniform to prepare a hair dye composition. The resultant hair dye composition was evaluated for rubfastness, feel in a dry state, feel during shampooing and shampooing resistance according to the above-mentioned methods.
Further, for confirming the sustainability of the effects of the composition on hair, the following shampooing resistance (difficulty of discoloration in 28-time shampooing), rubfastness after 28-time shampooing, and feel in a dry state after 28-time shampooing were evaluated. The results are shown in Table 8.
The blending amount (mass%) shown in the Table is an active ingredient amount.
The hair bundle treated in the same manner as in the above “shampooing resistance (difficulty of discoloration in 7-time shampooing)” was analyzed with the above-mentioned color difference meter in a CIE color system (L*,a*,b*). Then, this was shampooed with the model shampoo having a formulation mentioned above, rinsed with warm water at 40° C. and dried. The process was repeated for a total of 28 times. After shampooing 28 times, the dried hair bundle was analyzed with the color difference meter in the same manner as above, and a color difference (ΔE*) from the hair bundle before shampooing was calculated in the same manner as above.
The hair bundle treated in the same manner as in the above “rubfastness (difficulty of color transfer)” was shampooed with the model shampoo having a formation as above, rinsed with warm water at 40° C. and dried. The process was repeated for a total of 28 times. The hair bundle shampooed and dried 28 times was evaluated for the rubfastness according to the same method as above.
The hair bundle treated in the same manner as in the above “feel in dry state” was shampooed with the model shampoo having a formulation as above, rinsed with warm water at 40° C. and dried. The process was repeated 28 times. After shampooing 28 times, the feel of the dried hair bundle was evaluated in the same manner as above.
As in Table 8, when the hair dye composition of the present invention was applied to hair, a good feel was given in any of a dry state and a wet state, the composition was excellent in durability to friction, and even after washing 28 times, these effects were sustained. From this, it is considered that, in shampooing once a day, the hair dye effect can be sustained for about one month.
According to the present invention, there can be provided a cosmetic composition, which, when applied to keratin substances such as skin or hair, can give a good feel in any of a dry state and a wet state, and which is excellent in durability to friction, and even after washing, these effects can be sustained. In the case where the cosmetic composition is used as a hair dye composition, it can give a good feel to hair in any of a dry state and a wet state, and after hair dyeing, the color film peels little by friction, and can suppress secondary adhesion to clothes and pillows. In addition, after shampooing, discoloration is low and color sustainability is good, and further, even after shampooing, a good feel retains and a secondary adhesion suppressing effect can also be sustained.
