Description

Oily cosmetic

Technical Field

The present invention relates to an oil-based cosmetic that can change color tone by applying a light frictional force to a coating film at a desired timing after applying the cosmetic to the skin, and that can obtain a good sanding effect.

Background

In recent years, cosmetics, particularly makeup cosmetics, have become important elements of commercial value not only in that the color of a coating film is well developed when applied to the skin, but also in that novelty in the appearance color of the cosmetics themselves and specialization in use are essential.

For example, in a cosmetic containing particles in which a part or all of a coloring material such as a pigment is masked, the masking can be peeled off to expose the coloring material inside, and thus the color tone can be changed during or after application.

Patent document 1 describes: a soft resin capsule in which an oily inclusion is coated with a shell (capsule film) made of a soft resin insoluble in the inclusion, and a makeup cosmetic containing the soft resin capsule. The soft resin capsule is a compression-disintegrable capsule comprising an inclusion containing one or more coloring materials selected from a coloring pigment, a colored pearlescent pigment and an oil-soluble dye and an oil component, and a shell (capsule film) covering the inclusion. In the cosmetic disclosed in patent document 1, after the cosmetic is applied to the skin, the shell (capsule film) is broken by friction with a force exceeding the pressure (breaking) strength of the capsule, and the color material such as the encapsulated pigment is released. As a result, the color tone of the cosmetic coating film can be changed. However, in order to change the color tone, it is necessary to apply the skin with a large force, and broken capsules remain on the skin, and thus the cosmetic coating film may be adversely affected.

In view of the above-described problems of patent document 1, patent document 2 describes a cosmetic that can change the color tone of a coating film without applying a large force. The water-in-oil type cosmetic of patent document 2 contains soft aggregated particles containing a non-coloring pigment and carrageenan and/or xanthan gum in an internal aqueous phase, and the soft aggregated particles are disintegrated and developed only by applying the cosmetic. As a result, a cosmetic coating film having a color tone different from the original appearance color is formed.

Further, patent document 3 discloses a cosmetic containing a multilayer capsule containing a large amount of an ultraviolet scattering agent and a pigment. When the cosmetic is applied to the skin, the multi-layer capsule is disintegrated, and the apparent color of the exposed pigment can reduce the whiteness caused by a large amount of ultraviolet scattering agent. However, the cosmetics described in patent documents 2 and 3 are both cosmetics whose color tone changes when applied to the skin, and the color tone does not change at any timing after application.

Disclosure of Invention

Problems to be solved by the invention

The present invention addresses the problem of providing a cosmetic composition that, when applied to the skin, can easily change the color tone of a cosmetic coating film after application at any time, although the color tone is substantially unchanged.

For solving the problemsScheme (2)

As a result of intensive studies to solve the above problems, the present inventors have found that when a water-soluble abrasive is combined and blended with particles containing a pigment and having a part or all of the apparent color of the pigment masked, and the particle diameter and blending amount of the abrasive are within a predetermined range, the apparent color of the masked pigment is exposed and the color tone thereof is changed only by lightly rubbing the applied cosmetic coating film or only lightly rubbing the skin on which the cosmetic coating film is formed, thereby completing the present invention.

That is, the present invention provides an oil-based cosmetic composition comprising:

(a) particles containing a pigment in which a part or all of the apparent color of the pigment is masked, and

(b) a water-soluble abrasive having a particle diameter of 50 to 600 μm,

(b) the amount of the water-soluble abrasive is 2-20 mass% relative to the total amount of the cosmetic, and the mixing ratio [ (b)/(a) ] of the water-soluble abrasive (b) to the pigment-containing particles (a) is 0.5 or more and less than 2.5.

ADVANTAGEOUS EFFECTS OF INVENTION

When the oil-based cosmetic composition of the present invention contains particles containing a pigment having a different hue from that of the cosmetic composition, the color tone can be changed by only applying or wiping the composition lightly at any time after the makeup is performed, and the effect of refreshing the user can be obtained. Further, when particles containing a pigment of the same color system as the oil-based cosmetic (having a similar hue) are blended, a bright color can be obtained again by lightly rubbing the cosmetic coating film that fades with time, and makeup can be easily performed.

On the other hand, since the oily cosmetic of the present invention contains a polishing agent having an appropriate particle diameter, the particles are less likely to be crushed in the cosmetic production process, and the color tone is changed and a good polishing effect and a good massage effect can be obtained. Further, by using a water-soluble substance as the abrasive, the abrasive does not remain on the skin, and therefore the feeling of use is excellent.

Detailed Description

The oil-based cosmetic (hereinafter also referred to simply as "cosmetic") of the present invention contains, as essential components, (a) particles containing a pigment and (b) a water-soluble abrasive having a particle diameter of 50 to 600 [ mu ] m.

The components constituting the cosmetic of the present invention will be described in detail below.

< (a) pigment-containing particle

The pigment-containing particles (a) (hereinafter, may be simply referred to as "component (a)") to be blended in the cosmetic of the present invention may have any form as long as they are particles in which a part or all of the apparent color of a pigment generally used in cosmetics is masked. Examples thereof include multilayer capsule particles containing a pigment, aggregate particles in which a pigment and other components are integrated, and the like. Among them, from the viewpoint of easily adjusting the release of the pigment from the particles, it is preferable to use multilayer type capsule particles containing the pigment.

The pigment-encapsulated multilayer type capsule particle has a structure comprising an inner layer and 1 or more outer layers. The inner layer contains a color pigment such as a red inorganic pigment or a yellow inorganic pigment as an essential component, and the outer layer made of a polymer as a base material covers the inner layer. The outer layer based on a polymer may be further coated with a layer containing a functional pigment. The outer layer based on a polymer and the layer containing a functional pigment (inorganic powder) may be coated in any order, and may be a single layer or a plurality of layers. Inorganic powders may optionally be included in the inner and outer layers.

The polymer to be the base material is not particularly limited as long as it is a polymer that is generally used in cosmetics by a user, and examples thereof include (meth) acrylic resins such as polymethyl methacrylate, and organic polymers such as nylon, polyester, polyethylene, polystyrene, polyurethane, silicone resin, and cellulose.

The "color tone pigment" in the present invention is not particularly limited as long as it has a function of changing the color tone of the cosmetic. Examples of the pigment include red inorganic pigments such as red iron oxide, sintered iron oxide/titanium oxide, cadmium red and molybdenum red, and yellow inorganic pigments such as yellow iron oxide, cerium oxide, vanadium bismuth oxide yellow, chrome yellow and cadmium yellow.

The "functional pigment" in the present invention includes not only boron nitride and the like which are generally called functional pigments, but also pigments other than the "coloring pigments", for example, white pigments such as titanium oxide and zinc oxide, extender pigments such as talc, mica and silica, and the like.

Commercially available products include Magicolor (registered trademark) (Biogenic co., ltd.), mercapable Magic SP Series (manufactured by dado chemical industries), TagraCap (trademark) (タグラバイオテクノロジー), and MicroBeads (trademark) (サルボナテクノロジーズ).

The pigment-encapsulated multilayer capsule particle can be produced, for example, as follows: as described in U.S. patent publication No. 2011/0165208 a1 (corresponding japanese patent application laid-open publication No. 2011-529104), a1 st mixed solution is prepared by uniformly mixing a color tone pigment, a plasticizer, and a polymer in a1 st solvent, the prepared solution is spray-dried to form core particles in which the color tone pigment is coated with the polymer, the formed core particles and a functional pigment are uniformly mixed in a 2 nd solvent to prepare a 2 nd mixed solution, and the 2 nd mixed solution is spray-dried to produce multilayer capsule particles in which a coating layer of the functional pigment is formed outside the core particles.

In the multilayer capsule particle, the multilayer means 2 or 3 layers, or 3 or more layers, and preferably has a 2-layer structure composed of an inner layer containing a pigment and an outer layer based on a polymer, or a 3-layer structure in which the inner layer containing a pigment and the outer layer based on a polymer are further covered with a layer containing a functional pigment.

The shape of the multilayer capsule particle may be not only spherical, square, elliptical, etc., but also irregular, and the shape is not limited.

The component (a) of the present invention may be used as it is, or the surface thereof may be subjected to a hydrophobic treatment with a hydrophobic treatment agent usually used. The hydrophobizing surface treatment is not particularly limited, and examples thereof include an organosilicon treatment (treatment with a silicone oil such as methylhydrogenpolysiloxane, dimethylpolysiloxane or methylphenylpolysiloxane, an alkylsilane such as methyltrimethoxysilane, ethyltrimethoxysilane, hexyltrimethoxysilane or octyltrimethoxysilane, a fluoroalkylsilane such as trifluoromethylethyltrimethoxysilane or heptadecafluorodecyltrimethoxysilane), a fatty acid treatment (treatment with a palmitic acid, isostearic acid, stearic acid, lauric acid, myristic acid, behenic acid, oleic acid, abietic acid or 12-hydroxystearic acid), a fatty acid soap treatment (treatment with an aluminum stearate or calcium stearate), a fatty acid ester treatment (treatment with a dextrin fatty acid ester, cholesterol fatty acid ester, calcium stearate, or the like), a fatty acid ester treatment (treatment with a dextrin fatty acid ester, cholesterol fatty acid ester, a hydrogenated starch ester, and the like, Sucrose fatty acid ester, starch fatty acid ester, etc.). These hydrophobization treatments can be carried out according to a conventional method.

The particle diameter of the component (a) of the present invention is less than 300. mu.m, preferably 280 μm or less, more preferably 250 μm or less, further preferably 150 μm or less, further preferably 100 μm or less, and most preferably 60 μm or less. Here, the particle size means a number average particle size. When the particle diameter is 300 μm or more, the feeling of use of the cosmetic tends to be poor.

The amount of component (a) in the cosmetic of the present invention is not particularly limited as long as it is an amount sufficient to achieve a desired visual effect on the coated surface. For example, the amount of the cosmetic composition is 0.1 to 10% by mass, preferably 0.5 to 9.0% by mass, and more preferably 1.0 to 8.0% by mass, based on the total amount of the cosmetic composition. When the amount is less than 0.1% by mass, the change in color tone is difficult to obtain, and when it exceeds 10% by mass, the usability tends to be deteriorated.

(b) a water-soluble abrasive having a particle diameter of 50 to 600 μm

The water-soluble abrasive (hereinafter, sometimes simply referred to as "component (b)") to be blended in the cosmetic of the present invention is not particularly limited as long as it is a water-soluble powder having a particle size of 50 to 600 μm. From the viewpoint of less irritation to the skin and high safety (no problem occurs even when the powder is put into the mouth), it is preferable to use a powder containing a saccharide. As the saccharide, monosaccharide, polysaccharide, sugar alcohol, etc. can be used.

The term "water-soluble" in the present invention means: the solubility in water at 20 ℃ is at least 50g/100mL, preferably 100g/100mL or more, more preferably 150g/100mL or more.

Examples of the monosaccharide include glucose, fructose, xylose, mannose, and galactose, and examples of the polysaccharide include sucrose, trehalose, lactose, maltose, and cellulose.

Examples of the sugar alcohol include sorbitol, maltitol, xylitol, mannitol, lactitol, erythritol, and the like.

The component (b) of the present invention is preferably selected from the group consisting of fructose, sucrose, lactitol, xylitol and sorbitol. Sucrose is particularly preferred.

The amount of component (b) in the cosmetic of the present invention is 2 to 20% by mass, preferably 2 to 10% by mass, based on the total amount of the cosmetic. When the amount of the additive is less than 2% by mass, the following orientation is provided: the scrub agent is not sufficiently irritant to feel a massage effect, and it is difficult to obtain a change in color tone due to light friction. When the content exceeds 20% by mass, there arises a problem that (a) particles containing a pigment are crushed in the production of cosmetics.

The blending ratio (mass ratio) of the component (b) to the component (a) in the cosmetic of the present invention is 0.5 or more and less than 2.5, and more preferably 0.5 or more and less than 2.0. From the viewpoint that the component (a) is easily crushed after application and the component (a) is not easily crushed in the production of a cosmetic, the ratio (b)/(a) is preferably 1.5 or less, more preferably 1.25 or less, and still more preferably 1.0 or less.

In the cosmetic of the present invention, components generally used in cosmetics, such as oil components, coloring materials, oil-soluble coating agents, surfactants, lower alcohols (e.g., ethanol), moisturizers, ultraviolet absorbers, thickeners, fillers, stabilizers, antioxidants, antifoaming agents, preservatives, bactericides, pH regulators, vitamins, blood circulation promoters, whitening agents, skin activators, active ingredients, extracts from animals and plants, perfumes, and the like, may be blended as necessary within a range not to impair the effects of the present invention.

The term "oily cosmetic" as used herein means a cosmetic comprising an oily component and an oil-soluble component as main ingredients, and optionally water or a water-soluble component. The amount of "water" in the cosmetic of the present invention is preferably adjusted to an amount that the water-soluble abrasive ((b) component) as an essential component does not dissolve before use and thus loses the abrasive effect. For example, the amount of water blended in the cosmetic of the present invention is preferably 1% by mass or less, and more preferably 0.5% by mass or less, based on the total amount of the cosmetic. Further, it is more preferable to adopt a form of an anhydrous cosmetic containing no water.

The cosmetic of the present invention is preferably prepared as a solid cosmetic, and the hardness thereof is preferably 10 to 70gf (gram weight). Particularly, when the cosmetic stick is produced, the hardness is preferably 20 to 60 gf. Here, "hardness" means the following value: the samples molded into a rod shape were subjected to a load (50 gf released after pressing at 20 mm/s) by a durometer (manufactured by FUDO corporation) and the number of times of the load until the samples were bent was measured to evaluate the brittleness.

When the hardness of the cosmetic is less than 10gf, the base is too soft, and the pigment-containing particles are not crushed, so that sufficient color development cannot be obtained. On the other hand, if the hardness exceeds 70gf, the base is too hard, and the workability is deteriorated.

The oily cosmetic of the present invention may be provided in the form of a cosmetic or quasi-drug which has a sanding effect or a massage effect and can enjoy a change in color tone at any time. As the product form, makeup cosmetics for skin or hair, skin care cosmetics, and the like are set, but not limited to these. The makeup cosmetic is particularly preferably provided in the form of a solid makeup cosmetic for lips, eyes and cheeks, and the effects of the present invention can be effectively exhibited by such a configuration.

The cosmetic of the present invention can be produced based on a conventionally used method. For example, the composition can be produced by heating, stirring and mixing the components including the essential components, degassing, filling in a container, and cooling.

Examples

The present invention will be described in further detail with reference to the following examples, but the present invention is not limited to these examples. The amount of the additive is expressed in mass% unless otherwise specified.

Examples 1 to 8 and comparative examples 1 to 4

Oily cosmetics were prepared by a conventional method according to the formulations shown in tables 1 and 2 below.

Next, the obtained cosmetic was evaluated for (1) easiness of crushing the particles ((a) component), (2) usability (irritant effect of the matting agent), (3) easiness of handling at the time of production (the particles ((a) component) are not easily crushed in the production process), and (4) change in color tone by rubbing after coating. The evaluation methods of the respective items are as follows.

(1) Easiness of crushing of particles (component (a))

The cosmetic compositions of the respective examples (equal amounts) were applied to the same area of the nail on the hand of the subject to form a cosmetic coating film. Then, each coating film was rubbed by reciprocating a finger with a constant force, and the number of times of rubbing (reciprocating) until the color of the coating film was changed was evaluated.

A +: 3 times of reciprocating

A: 4 to 6 reciprocations

B: 7 to 10 reciprocations

C: more than 11 times of reciprocating

(2) Usability (stimulating effect of scrub agent)

The roughness felt when the cosmetic compositions of the respective examples (equal amounts) were applied to the lips and when the lips were rubbed against each other after application was evaluated.

A: strongly feel

B: slightly feel

C: can not feel

(3) Ease of handling during production (ease of crushing of the particles (component (a)) in the production process)

The cosmetics of each example were produced by mixing using a general-purpose mixing device (homogenizer), and evaluated as to whether or not the particles containing the pigment (component (a)) were crushed in the production process and whether or not the color tone of the cosmetics was changed.

A +: no change in hue was observed at all.

A: almost no change in hue was observed.

B: a faint change in color tone occurred, but the color tone of the entire cosmetic did not change.

C: the color tone of the cosmetic product as a whole is changed.

(4) Change in color tone caused by rubbing after coating

The evaluation was made by applying the cosmetic compositions of the respective examples (equal amounts) to the lips and then rubbing the lips with fingers or rubbing the lips against each other to change the color tone of the applied cosmetic composition. The application or rubbing is performed until the change in color tone of the cosmetics of each example is completed.

A +: the impression of the appearance of the lips varies significantly.

A: the appearance impression of the lips varies greatly.

B: the appearance impression of the lips hardly changes.

C: the appearance impression of the lips was not changed at all.

In the case of (4) "color change", the cosmetic in which "a +" or "a" is the evaluation result of color change when a warm pigment such as a red pigment is used as "(a) pigment-containing particles" also has an effect of improving a bloody feeling.

[ Table 2]

2; sucrose (about 300 μm)

As is clear from the results shown in tables 1 and 2, the oil-based cosmetic compositions (examples 1 to 8) satisfying the conditions that the water-soluble abrasive (b) is blended in a predetermined amount (2 to 20 mass%) and the blending ratio [ (b)/(a) ] of the (b) to the (a) is 0.5 or more and less than 2.5 can be produced satisfactorily without crushing the pigment-containing particles (a) in the production process. Further, it was confirmed that since a predetermined amount of the matting agent was added, the matting effect (or massage effect) was high, and the pigment-containing particles (a) were easily crushed by rubbing (rubbing) after coating, and the color tone was changed. However, in comparative example 2 in which the blending ratio [ (b)/(a) ] was 5, the particles (a) were crushed during the production process, and the color tone was not changed by rubbing (rubbing) after coating. Although comparative example 1 having a blending ratio [ (b)/(a) ] of 2.5 can avoid the problem that the particles (a) are crushed during the production process, the blending ratio of the matting agent is too high, and therefore the particles are crushed when the cosmetic is applied, and a change in color tone due to rubbing (rubbing) of the particles with each other after the application is observed. Although the color tone change was observed in comparative example 3 in which no matting agent was blended, the number of applications (rubbing against each other) required to obtain a color tone change was extremely large, and thus it was not practical. In comparative example 4 in which the pigment-containing particles were not blended, the color tone was not changed even when the coating (rubbing) was performed.
