Description
Technical Field
The present invention relates to a cosmetic.
Background
There is a high demand for cosmetics that can cope with the defects of skin such as wrinkles, and various cosmetics are on the market that emphasize the blending of active ingredients, concealment due to visual effects, and the like.
As effective ingredients capable of obtaining wrinkle-improving effects, ingredients such as niacinamide, retinol, and Na (common name: NEI-L1) are recognized by Ministry of health and labor in Japan, and are incorporated into medicinal cosmetics (non-standard medicines).
On the other hand, in cosmetics, powder is blended for the purpose of obtaining various effects.
Patent document 3 discloses a cosmetic containing a coating powder containing a base material and fine red iron oxide particles coated on the base material.
Patent document 5 discloses cosmetic particles in which amorphous titanium oxide is supported on the surface of metal oxide particles, and a cosmetic composition using the same.
Patent document 1: japanese patent laid-open No. 2008-291027
Patent document 2: japanese patent laid-open publication No. 2013-142103
Patent document 3: japanese patent laid-open No. 2020 and 70235
Patent document 4: japanese laid-open patent publication No. 11-27322
Patent document 5: japanese patent laid-open publication No. 2017-33221
Cosmetics containing an active ingredient having an effect of improving wrinkles (i.e., an anti-wrinkle agent) such as niacinamide require a certain continuous use period before it can be determined whether or not the effect of improving wrinkles is obtained.
Here, in the present invention, the "anti-wrinkle agent" means an active ingredient that is recognized by the ministry of health and labor in japan to exert a wrinkle-improving effect by continuing to be applied to the skin.
On the other hand, in cosmetics in which the anti-wrinkle effect is emphasized, obtaining a sense of improvement in wrinkles from immediately after the start of use is an important factor as a motivation for urging a user to continue using the cosmetics for a long period of time. Therefore, in addition to the fundamental wrinkle improvement effect by the anti-wrinkle agent, a cosmetic that can feel the wrinkle improvement feeling from immediately after the cosmetic is used is desired.
As a measure for obtaining a wrinkle-improving feeling immediately after the start of use while containing an anti-wrinkle agent, the present inventors have found that a visual effect of reducing wrinkles is exhibited by applying a cosmetic containing a powder to a wrinkle part (for example, by coating) and applying the cosmetic to the wrinkle part (hereinafter, also referred to as a "wrinkle hiding effect"). According to this method, a wrinkle hiding effect can be obtained by the soft focusing effect due to the powder content.
On the other hand, when a powder is incorporated into a cosmetic, it is necessary to prevent the use feeling, properties, and the like of the cosmetic from being impaired. For this reason, it is preferable to use a powder that has a reduced content of powder and/or has little influence on a cosmetic base material (e.g., oil agent). As the powder having a small influence on the cosmetic base material, for example, a powder having a small refractive index difference from the cosmetic base material can be used. However, the use of a powder having a small refractive index difference from the cosmetic base material requires the cosmetic to contain a large amount of powder, which may affect the use feeling, properties, and the like of the cosmetic. Therefore, when selecting a powder, it is necessary to select a powder that can obtain an effective wrinkle hiding effect even if it is contained in a small amount.

[ cosmetics ]
The cosmetic of the present invention contains: an anti-wrinkle agent; an oil agent having a content of 10 to 95% by mass based on the total mass of the cosmetic; and powder X, wherein the absolute value of the refractive index difference relative to the refractive index of the oil agent is more than 0.1 and less than 1.0, and the content relative to the total mass of the cosmetic is 0.5-10 mass%.
The cosmetic of the present invention contains an anti-wrinkle agent, and therefore, can be expected to have a fundamental wrinkle-improving effect and an excellent wrinkle-concealing effect. The reason why the cosmetic of the present invention can exhibit such an effect is not clear, but the present inventors presume as follows.
The cosmetic of the present invention contains an anti-wrinkle agent, and thus can be expected to have a fundamental wrinkle improvement effect based on the effect of the anti-wrinkle agent exerted by long-term continuous use. The cosmetic of the present invention contains an oil agent at a content of 10 to 95% by mass, and contains powder X at a content of 0.5 to 10% by mass, the absolute value of the difference in refractive index with respect to the refractive index of the oil agent being 0.1 or more and 1.0 or less, and thus is presumed to exhibit an appropriate light scattering effect (i.e., soft focusing effect) and to be excellent in wrinkle hiding effect.
The wrinkle hiding effect exhibited by the cosmetic composition of the present invention is an effect that can be perceived from the beginning of the use of the cosmetic composition. Therefore, it is presumed that by using the cosmetic of the present invention, together with the expected feeling of the fundamental wrinkle improvement effect due to the inclusion of the anti-wrinkle agent, the improvement feeling of wrinkles can be felt immediately after the cosmetic is used. The above presumption is not to be construed as limiting the cosmetic of the present invention, but is described as an example.
On the other hand, conventional cosmetics including the techniques described in patent documents 1 to 5 do not pay attention to both the inclusion of an anti-wrinkle agent and the wrinkle hiding effect.
Hereinafter, each component contained in the cosmetic of the present invention will be described in detail.
[ (A) anti-wrinkle agent ]
The cosmetic of the present invention contains an anti-wrinkle agent.
The cosmetic of the present invention may contain 1 kind of anti-wrinkle agent alone or 2 or more kinds of anti-wrinkle agents.
The anti-wrinkle agent is not particularly limited, and may be appropriately selected from anti-wrinkle agents that can be contained in cosmetics. Examples of the anti-wrinkle agent include niacinamide, retinol, and trifluoroisopropyloxypropylaminocarbonylpyrrolidine carbonylmethylpropylaminocarbonylbenzoyl glycine Na.
As the anti-wrinkle agent contained in the cosmetic of the present invention, niacinamide is preferable from the viewpoint of its wrinkle-improving effect and high stability when contained in the cosmetic.
Niacinamide is a niacinamide compound, known as one of the water-soluble vitamins, vitamin B group. The nicotinamide may be an extract extracted from a natural product such as rice sugar, or a synthetic product synthesized by a known production method. As nicotinamide, commercially available products on the market can be used. Specifically, nicotinamide as recorded in the 17 th revised japanese pharmacopoeia can be used.
The content of the anti-wrinkle agent in the cosmetic of the present invention is not particularly limited.
The content of the anti-wrinkle agent is, for example, preferably 0.1 to 10% by mass, more preferably 1 to 10% by mass, even more preferably 2 to 8% by mass, and most preferably 4 to 6% by mass, based on the total mass of the cosmetic.
If the content of the anti-wrinkle agent is 0.1% by mass or more based on the total mass of the cosmetic, the effect of improving wrinkles by the anti-wrinkle agent can be expected. When the content of the anti-wrinkle agent is 10% by mass or less based on the total mass of the cosmetic, the anti-wrinkle agent tends to be stably contained in the cosmetic.
[ (B) oil preparation ]
The cosmetic of the present invention comprises an oil agent.
As the oil agent, those which are generally used as components of oil agents in the field of cosmetics can be used.
The oil agent may be liquid, semisolid, solid, or a mixture thereof.

The oil agent can also be selected from the viewpoint of imparting viscosity, hardness, and the like to the cosmetic.
As the oil agent, commercially available products can be used.
Examples of the silicone oil include chain polysiloxanes such as dimethylpolysiloxane (polydimethylsiloxane), methylphenylpolysiloxane, and methylhydrogenpolysiloxane, cyclic polysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and tetramethyltetrahydrocyclotetrasiloxane, and octylmethicone.
Examples of the silicone wax include (acrylate/stearyl acrylate/polydimethylsiloxane methacrylate) copolymers and (acrylate/behenyl acrylate/polydimethylsiloxane methacrylate) copolymers.
The silicone gel is a silicone crosslinked product in which silicone chains constituting a main chain skeleton are crosslinked with each other by a polyether chain, a polyglycerol chain, a silicone chain, or the like. Depending on the structure of the chain used for crosslinking, there are various types such as polyether-modified silicone gel, polyglycerol-modified silicone gel, polyether-alkyl co-modified silicone gel, and polyglycerol-alkyl co-modified silicone gel. The cosmetic of the present invention can use these silicone gels as an oil agent without limitation.
Specific examples of the silicone gel include (dimethicone/(PEG-10/15) crosspolymer, (PEG-15/lauryl dimethicone) crosspolymer, (PEG-10/lauryl dimethicone) crosspolymer, (PEG-15/lauryl dimethiconoethyl dimethicone) crosspolymer, (dimethicone/polyglycerin-3) crosspolymer, (lauryl dimethicone/polyglycerin-3) crosspolymer, (polyglycerin-3/lauryl dimethiconoethyl dimethicone) crosspolymer, (dimethicone/vinyl dimethicone) crosspolymer, (dimethicone/phenyl vinyl dimethicone) crosspolymer, and the like, (vinyl dimethicone/lauryl dimethicone) crosspolymer, (lauryl dimethicone ethyl dimethicone/bisvinyl dimethicone) crosspolymer, and the like.

The content of the oil agent in the cosmetic of the present invention is 10 to 95% by mass based on the total mass of the cosmetic. The content of the oil agent can be determined appropriately according to the form of the target cosmetic. The content of the oil agent of 10 to 95% by mass means that the oil agent is contained as one of the components contained in the cosmetic of the present invention.
For example, when the cosmetic of the present invention is used as an oily cosmetic, the content of the oil agent is preferably 20 to 95% by mass, more preferably 20 to 90% by mass, and still more preferably 30 to 85% by mass, based on the total mass of the cosmetic.
[ (C) powder X ]
The cosmetic of the present invention contains a powder X having a refractive index difference of 0.1 to 1.0 in absolute value with respect to the refractive index of an oil agent.
The absolute value of the refractive index difference between the powder X and the refractive index of the oil agent is 0.1 or more and 1.0 or less, more preferably 0.3 or more and 1.0 or less, and still more preferably 0.9 or more and 1.0 or less.
When the absolute value of the refractive index difference is 0.1 or more, it is not necessary to contain a large amount of powder in order to obtain the wrinkle hiding effect, and the degree of freedom in designing the cosmetic composition tends to be improved. On the other hand, if the absolute value of the refractive index difference is 1.0 or less, when the composition is applied (for example, applied) to the skin, appropriate light scattering is caused, whitening of the appearance of the skin is suppressed, and a good wrinkle hiding effect tends to be obtained.
In the present invention, the refractive indices of the powder X and the oil agent are values measured according to method B (Pecke method) described in JIS K7142: 2014.
The absolute value of the refractive index difference between the refractive index of the powder X and the refractive index of the oil agent was calculated as the absolute value of the value obtained by measuring the refractive index of the powder X and the refractive index of the oil agent, respectively, and subtracting the refractive index of the powder X from the refractive index of the oil agent.
When a plurality of types of powder X are contained in a cosmetic, the content mass ratio and the refractive index of the plurality of types of powder X constituting the powder X are measured, and the refractive index of the powder X is determined as a value calculated by weighted averaging the obtained refractive indices based on the content mass ratio.
When a cosmetic contains a plurality of oils, the refractive index is calculated in the same manner as in the case of the powder X.
The powder X may be an inorganic powder, a metal oxide powder, or a composite powder of a metal oxide and an inorganic material, and is preferably a composite powder of a metal oxide and an inorganic material.
The form of the powder X is not particularly limited.
The powder X is preferably a spherical powder or a plate-like powder, and more preferably a spherical powder, from the viewpoint of efficiently reflecting light and more preferably exhibiting a wrinkle hiding effect.
The spherical powder includes not only spherical powder but also approximately spherical powder.
The spherical powder may have irregularities on the surface.
When the form of the powder X is spherical, wrinkles, which are recesses on the skin surface, can be satisfactorily filled. It is considered that when the specific powder is well filled in wrinkles, the wrinkle-concealing effect by light scattering can be more satisfactorily exhibited.
Examples of the powder included in the powder X include inorganic powders (for example, talc, kaolin, mica, sericite (sericite), muscovite, phlogopite, synthetic mica, lepidolite, biotite, vermiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, aluminum hydroxide, metal tungstate, magnesium, hollow silica, zeolite, barium sulfate, calcined calcium sulfate (calcined gypsum), calcium phosphate, fluorapatite, hydroxyapatite, ceramic powder, and the like), metal soaps (for example, zinc myristate, calcium palmitate, aluminum stearate), boron nitride, and the like); metal oxide powders (e.g., titanium dioxide, zinc oxide, etc.); crosslinked hydrocarbon polymers (crosslinked materials such as nylon, polyethylene, polyurethane, and polystyrene); metal oxide and inorganic composite powder (silica and zinc oxide, silica and titanium dioxide, silica and iron oxide, silica and aluminum hydroxide, PMMA and zinc oxide, PMMA and titanium dioxide, PMMA and iron oxide, PMMA and aluminum hydroxide, mica and zinc oxide, mica and titanium dioxide, mica and iron oxide, mica and aluminum hydroxide, talc and zinc oxide, talc and titanium dioxide, talc and iron oxide, talc and aluminum hydroxide), etc.
The powder contained in the powder X may be a powder composed of a single component or a powder composed of 2 or more components. Examples of the composite powder of a metal oxide and an inorganic material include a composite powder obtained by coating a powder with a metal oxide or the like, and a modified powder obtained by treating the surface of a powder with a compound or the like.
The cosmetic of the present invention may contain 1 kind of powder X alone, or may contain 2 or more kinds of powder X.
The powder X is preferably a composite particle containing silica or mica and a metal oxide such as titanium oxide or zinc oxide, and more preferably a composite powder containing silica and titanium oxide.
Commercially available powder X can be used.
Examples of commercially available products include BA-1 and BA-4(JGC C & C, hollow silica particles), HCS Refle 30, HCS Refle 50, and HCS Refle 90(JGC C & C, composite particles of silica and titanium oxide), MZS-5104(SUZUKI YUUSHI INDUSTRIAL CORPORA TION, composite particles of mica and zinc oxide), PULZA OPZ-50(SUZUKI YUUSHI INDUSS TRIAL CORPORATION, composite particles of PMMA and zinc oxide), PULZA SIZ-30(SUZUKI YUUSUSTINSTINSTINSHI CORPORATION, composite particles of silica and zinc oxide), COV ERLEAF MF (B) (JGC C & C, composite particles of mica, titanium oxide, iron oxide, etc.).
The commercially available product usable as the powder X is not limited to these.
The particle size of the powder X is not particularly limited.
The particle diameter of the powder X is, for example, preferably 1 to 20 μm, more preferably 3 to 15 μm, and still more preferably 3 to 10 μm.
When the particle diameter of the powder X is in the above range, the friction feeling when pushing the cosmetic against the skin is suppressed, and the slidability tends to be improved.
In the present invention, the particle diameter of the powder is a volume average particle diameter (Mv) which is a value measured by using a laser diffraction/scattering type particle diameter distribution measuring apparatus.
As the laser diffraction/scattering type particle size distribution measuring apparatus, for example, particle LA-960 (product name) of HORIBA, ltd. However, the laser diffraction/scattering particle size distribution measuring apparatus is not limited to this.
The content of the powder X is 0.5 to 10% by mass, more preferably 0.5 to 5% by mass, and still more preferably 1 to 5% by mass, based on the total mass of the cosmetic, from the viewpoint of the feeling of use of the cosmetic.
When the content of the powder X is 0.5 mass% or more, an appropriate light scattering effect can be exhibited, and the wrinkle hiding effect can be contributed. When the content of the powder X is 10% by mass or less, the influence on the feeling of use of the cosmetic tends to be suppressed.
[ (D) powder Y ]
The cosmetic of the present invention preferably contains powder Y having an oil absorption of 1mL/100g to 150mL/100g, and an absolute value of refractive index difference with respect to the refractive index of the oil agent of less than 1.0. The cosmetic of the present invention contains powder Y, and both the wrinkle hiding effect and the removal inhibition effect can be easily achieved.
Here, in the present invention, "removal of makeup" means a state in which the applied makeup base such as foundation is not left at a desired application position on the skin, and means that unevenness, whitening, and the like are generated.
Cosmetics containing an anti-wrinkle agent are generally constituted as skin care cosmetics. In this case, makeup cosmetics such as foundation are applied to the skin after the skin care cosmetics are applied. However, when a makeup base cosmetic is applied to the skin after applying a skin care cosmetic containing an oil agent or the like, makeup removal may occur depending on the situation. Therefore, although it is important to achieve both the wrinkle hiding effect and the makeup removal inhibition in the cosmetic containing the anti-wrinkle agent and the oil agent, the cosmetic of the present invention also exhibits the unexpected secondary effect of being able to cope with both the wrinkle hiding effect and the makeup removal inhibition by containing the powder Y having an oil absorption of 1mL/100g to 150mL/100 g.
The oil absorption of the powder Y is 1mL/100g to 150mL/100g, more preferably 1mL/100g to 130mL/100g, and still more preferably 30mL/100g to 130mL/100g, from the viewpoint of achieving both the wrinkle hiding effect and the removal prevention effect.
Further, when the oil absorption amount of the powder Y is within the above range, friction in the cosmetic is reduced, and the slidability when pushing the cosmetic away is improved, so that the suppression of uneven application is further improved when makeup is performed after the cosmetic of the present invention is applied.
Measurement of oil absorption according to JIS K5101-13-1: 2004.
The powder Y is a powder in which the absolute value of the refractive index difference with respect to the refractive index of the oil agent exceeds 1.0. The refractive index of powder Y can be measured in the same manner as the refractive index of powder X.
The powder Y may be selected from powders having a refractive index difference relative to the refractive index of the oil agent of less than 1.0 and an oil absorption of 1mL/100g to 150mL/100 g.
The powder Y may be inorganic particles or organic particles.
The powder Y is preferably silica or a polymethyl methacrylate resin (PMMA resin), and more preferably silica.
Commercially available powder Y can be used.
Examples of commercially available products of the specific powder include E-2C, D-11C, D-25C, E-90C, G-6C (SUZUKI YUUSHI INDUSTRIAL CORPORATION, silicon dioxide).
The particle size of the powder Y is not particularly limited.
The particle diameter of the powder Y is, for example, preferably 1 to 20 μm, more preferably 3 to 15 μm, and still more preferably 3 to 10 μm.
When the particle diameter of the powder Y is in the above range, the friction feeling when pushing the cosmetic on the skin is suppressed, and the sliding property tends to be improved.
The particle diameter of the powder Y can be measured by the method described above.
The cosmetic of the present invention may contain 1 kind of powder Y alone, or may contain 2 or more kinds of powder Y.
The content of the powder Y is preferably 20 to 50% by mass, and more preferably 30 to 50% by mass, based on the total mass of the cosmetic.
When the content of the powder Y is within the above range, precipitation of the powder is suppressed, and favorable dispersibility is obtained, and the feeling of use of the cosmetic tends to be well maintained.
[ other ingredients ]
The cosmetic of the present invention may contain other components as necessary within a range not impairing the effects of the present invention.
Examples of the other components include an ultraviolet absorber, an aqueous medium (water, a lower alcohol, a polyhydric alcohol, and a solvent capable of dissolving nicotinamide), a preservative (phenoxyethanol, methyl paraben, and the like), a carotenoid (astaxanthin and the like), a thickener, an emulsifier, a pH adjuster, an emollient, a moisturizer, an antioxidant (tocopherol, and the like), a whitening agent, a colorant, a perfume, and the like.

As shown in Table 2, the cosmetics of examples 6 to 12 all had excellent wrinkle-concealing effects. Further, it is found that the powder Y has an improved effect of suppressing makeup removal.
[ relationship between powder X and wrinkle-concealing Effect ]
A cosmetic was prepared in the same manner as in example 1 except that the type and content of powder X were changed in the composition of the cosmetic in example 1, and the relationship between the type and content of powder X and the wrinkle concealing effect was evaluated. Details of the type and content of the powder X in the cosmetic prepared for evaluation are shown in the following groups (1), (2), and (3).
(1) Group (2): instead of HCS-Refle 90, 4 kinds of cosmetics were prepared in which the content of powder X was changed to 1 mass%, 3 mass%, 5 mass%, and 10 mass%, respectively, using BA-4(JGC C & C, silica particles) as powder X.
(2) Group (2): 3 types of cosmetics were prepared by changing the content of powder X to 1 mass%, 3 mass%, and 5 mass%, respectively, using HCS Refle 30 as powder X instead of HCS-Refle 90.
(3) Group (2): 5 types of cosmetics were prepared by changing the content of HCS Refle 90 to 0.5 mass%, 0.75 mass% (example 1), 1 mass%, 1.5 mass%, and 3 mass%, respectively.
Each of the obtained cosmetics was subjected to a treatment in a similar manner to "evaluation a: wrinkle hiding effect evaluation of wrinkle hiding effect was performed in the same manner, and a wrinkle score was obtained. Fig. 1 shows a graph in which the obtained wrinkle score is taken as the vertical axis and the content of powder X is taken as the horizontal axis.
In fig. 1, the cosmetic groups of the group (1) were plotted using triangles (a), the cosmetic groups of the group (2) were plotted using four corners (■), and the cosmetic groups of the group (3) were plotted using diamonds (diamond-solid).
The absolute values of the refractive index differences of the oil solutions of the powder X used in the above groups (1), (2), and (3) were 0.12, 0.36, and 0.98, respectively.
The values of the above-mentioned refractive index differences are also denoted in fig. 1.
As can be seen from fig. 1, the powder having a refractive index difference closer to 1.0 in the wrinkle score was better in the wrinkle score at a low concentration. This is considered to be because the refractive index difference is large and the light scattering property increases.
[ relationship between refractive index difference between powder and oil and wrinkle hiding effect: reference example)
A silicone gel (trade name: KSG-16, Shin-Etsu Chemical co., Ltd.): an oil solution containing triethylhexanoic acid (trade name: NOMCOAT TIO, Nisshin oiio co., Ltd.) -60: 14 and various powders shown in table 3 below were mixed using a mortar so that the content of the powders was 5 mass% based on the total mass of the composition, to prepare a composition (sample for evaluation) containing the oil solution and the powders.
The refractive index (weighted average) of the oil agent was 1.40.
Table 3 shows the absolute value of the value obtained by subtracting the refractive index of the powder from the refractive index of the oil agent (absolute value of the refractive index difference).
Each of the obtained evaluation samples was evaluated in a manner similar to "evaluation a: wrinkle hiding effect in the same manner, the wrinkle hiding effect was evaluated, and a "wrinkle score" was obtained.
The results of the "wrinkle scoring" obtained are also marked in table 3. Fig. 4 shows a graph in which the obtained "wrinkle score" is represented on the vertical axis and the type of powder is represented on the horizontal axis.
At the right end of the graph shown in fig. 4, an area of A, B or C indicated by two arrows corresponds to the rank of the evaluation criterion of evaluation a.
