Description

Oily cosmetic

Technical Field

The present invention relates to an oily cosmetic capable of changing color tone by applying a light friction force to a coating film at a desired timing after applying the cosmetic to the skin, and obtaining a good frosting effect.

Background

In recent years, not only the color of a coating film when applied to the skin is excellent, but also the novelty of the appearance color of the cosmetic itself and the specialization of the use have become important factors for commercial value for cosmetics, particularly make-up cosmetics.

For example, a cosmetic product containing particles in which a part or all of a coloring material such as a pigment is masked can be modified in color tone at the time of application or after application because the masking is removed to expose the coloring material.

Patent document 1 describes: a soft resin capsule in which an oily inner coating is coated with a shell (capsule film) formed of a soft resin insoluble in the inner coating, and a makeup cosmetic containing the soft resin capsule. The soft resin capsule is a capsule having a compression disintegrability, which comprises an inner coating containing one or more pigments selected from the group consisting of colored pigments, colored pearlescent pigments and oil-soluble dyes and an oil component, and a shell (capsule film) covering the inner coating. In the cosmetic described 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-resistant (breaking) strength of the capsule, and the coloring material such as the pigment contained therein is discharged. 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 a large force to the skin, and the damaged capsule remains on the skin, so that the cosmetic film may be adversely affected.

In view of the above problems of patent document 1, patent document 2 describes a cosmetic capable of changing the color tone of a coating film even if the coating is not applied with a large force. The water-in-oil cosmetic of patent document 2 contains soft aggregated particles containing a non-coloring pigment and carrageenan and/or xanthan gum in an inner aqueous phase, and the soft aggregated particles disintegrate and develop color only by applying the cosmetic. As a result, a cosmetic film having a color tone different from the original appearance color is formed.

Further, patent document 3 discloses a cosmetic which incorporates a multilayer capsule containing a large amount of an ultraviolet scattering agent and a pigment. When the cosmetic is applied to the skin, the multilayered capsule disintegrates, and the appearance color of the exposed pigment can alleviate whiteness caused by a large amount of ultraviolet scattering agent. However, the cosmetics described in patent documents 2 and 3 are each cosmetics in which the 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 product which is capable of easily changing the color tone of a cosmetic film after application at any timing, while the color tone is substantially unchanged when the cosmetic product is applied to the skin.

Solution for solving the problem

As a result of intensive studies to solve the above problems, the present inventors have found that, by combining and blending particles containing a pigment and having a part or all of the appearance color of the pigment masked with a water-soluble abrasive and having a particle diameter and a blending amount of the abrasive within predetermined ranges, the appearance color of the masked pigment is exposed and the color tone is changed only by lightly rubbing a cosmetic coating film after application or only by lightly rubbing the skin on which the cosmetic coating film is formed, and have completed the present invention.

Namely, the present invention provides an oily cosmetic comprising:

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

(b) A water-soluble abrasive agent with the particle diameter of 50-600 mu m,

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

ADVANTAGEOUS EFFECTS OF INVENTION

When the oily cosmetic of the present invention contains particles containing a pigment having a different hue from the cosmetic, the color tone can be changed by merely lightly rubbing or wiping at any timing after the application of the cosmetic, and the oily cosmetic has an effect of stimulating the user's mind. Further, if particles containing a pigment of the same color system (color phase close) as the oily cosmetic are blended, vivid color development 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 the abrasive agent having an appropriate particle diameter, the phenomenon that particles are crushed is not easily generated in the cosmetic production process, and the color tone is changed, and a good abrasive effect and a good massaging effect can be simultaneously perceived. In addition, since the water-soluble substance is used as the abrasive, the abrasive does not remain on the skin, and thus the feeling of use is excellent.

Detailed Description

The oily cosmetic of the present invention (hereinafter also simply referred to as "cosmetic") contains (a) particles containing a pigment and (b) a water-soluble abrasive having a particle diameter of 50 to 600 μm as essential components.

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

(a) particles comprising pigment

The particles (a) containing a pigment (hereinafter, may be simply referred to as "component (a)") blended in the cosmetic of the present invention may be in any form as long as part or all of the apparent color of the pigment usually used in cosmetics is masked. Examples of the particles include multilayered capsule particles in which pigment is encapsulated, and aggregated particles in which pigment and other components are integrated. Among them, from the viewpoint of easy adjustment of the discharge of pigment from the particles, multilayer capsule particles in which pigment is encapsulated are preferably used.

The pigment-encapsulated multilayer capsule particles have a structure comprising an inner layer and 1 or more outer layers. The inner layer is covered with an outer layer containing a color tone pigment such as a red inorganic pigment or a yellow inorganic pigment as an essential component and a polymer as a base material. The outer layer made of a polymer as a base material may be further coated with a layer containing a functional pigment. The outer layer made of a polymer as a base material 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. The inner and outer layers may optionally contain inorganic powders therein.

The polymer to be the base material is not particularly limited as long as it is a polymer that is used for a normal cosmetic product, and examples thereof include (meth) acrylic resins such as polymethyl methacrylate, and organic polymers such as nylon, polyester, polyethylene, polystyrene, polyurethane, silicone resins, 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 cosmetics. Examples of pigments commonly referred to as "coloring pigments" include red inorganic pigments such as red iron oxide, iron oxide/titanium oxide sinter, cadmium red, and molybdenum red, and yellow inorganic pigments such as yellow iron oxide, cerium oxide, bismuth vanadium oxide yellow, chrome yellow, and cadmium yellow.

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

The commercial product may be a product of the type of Magicolor (registered trademark) (Biogenic co., ltd), sugarcapsule Magic SP Series (manufactured by dado industries), tagraCap (manufactured by tarring corporation), microblads (manufactured by tarry corporation), and microblads (manufactured by tarry corporation).

The pigment-encapsulated multilayer capsule particles can be produced, for example, as follows: as described in U.S. patent publication No. 2011/0165208 A1 (corresponding japanese patent application 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, core particles having the color tone pigment covered with the polymer are formed by spray-drying the prepared solution, a 2 nd mixed solution is prepared by uniformly mixing the formed core particles and functional pigment in a 2 nd solvent, and a 2 nd mixed solution is spray-dried to produce multilayered capsule particles having a coating layer of the functional pigment formed outside the core particles.

In the multilayered capsule particle, the number of layers is 2 or 3 or more, preferably a 2-layer structure composed of an inner layer of an encapsulated pigment and an outer layer of a polymer as a base material, or a 3-layer structure in which the inner layer of the encapsulated pigment and the outer layer of the polymer as a base material are further coated with a layer containing a functional pigment.

The shape of the multilayered capsule particles may be not limited, and may be an irregular shape, other than spherical shape, square shape, elliptical shape, or the like.

The component (a) of the present invention may be used as it is, or may be used after the surface thereof is subjected to a hydrophobization treatment with a conventionally used hydrophobization agent. The hydrophobizing surface treatment is not particularly limited, and examples thereof include silicone treatment (treatment with methyl hydrogen polysiloxane, dimethyl polysiloxane, methyl phenyl polysiloxane, and other silicone oils; methyl trimethoxysilane, ethyl trimethoxysilane, hexyl trimethoxysilane, octyl trimethoxysilane, and other fluoroalkyl silanes; trifluoromethyl ethyl trimethoxysilane, heptadecafluoro decyl trimethoxysilane, and other), fatty acid treatment (treatment with palmitic acid, isostearic acid, stearic acid, lauric acid, myristic acid, behenic acid, oleic acid, abietic acid, 12-hydroxystearic acid, and other substances), fatty acid soap treatment (treatment with aluminum stearate, calcium stearate, and other substances), fatty acid ester treatment (treatment with dextrin fatty acid ester, cholesterol fatty acid ester, sucrose fatty acid ester, starch fatty acid ester, and other substances), and the like. These hydrophobization treatments may be carried out according to conventional methods.

The particle diameter of the component (a) of the present invention is less than 300. Mu.m, preferably 280. Mu.m, more preferably 250. Mu.m, still more preferably 150. Mu.m, still more preferably 100. Mu.m, and most preferably 60. Mu.m. The particle diameter herein means a number average particle diameter. When the particle diameter is 300 μm or more, the feel of the cosmetic tends to be poor.

The amount of the component (a) blended in the cosmetic of the present invention is not particularly limited as long as the amount is such that the desired visual effect is achieved in the coated surface. For example, the content 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. If the blending amount is less than 0.1 mass%, it is difficult to obtain a change in color tone, and if it exceeds 10 mass%, the usability tends to be poor.

(b) Water-soluble abrasive agent with particle size of 50-600 mu m

The water-soluble abrasive (b) (hereinafter, sometimes simply referred to as "component (b)") to be incorporated in the cosmetic of the present invention is not particularly limited as long as it is a powder having water solubility and a particle diameter of 50 to 600 μm. From the viewpoints of less skin irritation and high safety (no problem even when entering the mouth), a powder containing a saccharide is preferably used. As the saccharide, monosaccharides, polysaccharides, sugar alcohols, and the like can be used.

"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 monosaccharides include glucose, fructose, xylose, mannose, galactose, and examples of polysaccharides include sucrose, trehalose, lactose, maltose, and cellulose.

As sugar alcohols, sorbitol, maltitol, xylitol, mannitol, lactitol, erythritol and the like can be mentioned.

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) blended 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. If the amount is less than 2% by mass, the following tends to be present: the abrasive agent is insufficient in stimulus, and it is difficult to feel a massage effect and to obtain a change in color tone due to light friction. When the content exceeds 20% by mass, the pigment-containing particles may be crushed (a) in the production of cosmetics.

In the cosmetic of the present invention, the blending ratio (mass ratio) of the component (b) to the component (a) is (b)/(a) =0.5 or more and less than 2.5, more preferably 0.5 or more and less than 2.0. From the viewpoint of the component (a) being easily crushed after application and the component (a) being less likely to be crushed when a cosmetic is produced, (b)/(a) is preferably 1.5 or less, more preferably 1.25 or less, and even more preferably 1.0 or less.

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

The cosmetic of the present invention is preferably prepared as a solid cosmetic, and its hardness is preferably 10 to 70gf (gram weight). In particular, in the case of producing a stick cosmetic, hardness of 20 to 60gf is preferable. "hardness" herein refers to the following values: the sample molded into a rod shape was subjected to a load (after extrusion at 20mm/s and release of 50 gf) by a durometer (manufactured by FUDO Co.), and the number of times of load until the sample was bent was measured to evaluate the value at the time of brittleness.

When the hardness of the cosmetic is less than 10gf, the base is too soft, and the pigment-containing particles are not crushed, and sufficient color development is not obtained. On the other hand, when the hardness exceeds 70gf, the base is too hard and the use becomes poor.

The oily cosmetic of the present invention may be provided in the form of a cosmetic or quasi-drug having a frosting effect or a massaging effect and capable of enjoying a change in color tone at any timing. As the product form, make-up cosmetics for skin or hair, skin care cosmetics, and the like are set, but are not limited thereto. Among makeup cosmetics, the solid makeup cosmetics for lips, eyes and cheeks are particularly suitable, and by adopting these means, the effects of the present invention can be effectively exhibited.

The cosmetic of the present invention can be manufactured based on a method conventionally used. For example, the above-described components can be produced by heating, stirring, mixing, degassing, filling a container, and cooling.

Examples

The present invention will be further illustrated in detail by the following examples, but the present invention is not limited to these examples. The amount is expressed as mass% unless otherwise specified.

Experimental 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, with respect to the obtained cosmetics, (1) the crushing easiness of the particles ((a) component), (2) the usability (the irritation effect of the abrasive), (3) the handling easiness at the time of manufacture (the particles ((a) component) are not easily crushed in the manufacturing process), and (4) the change in color tone due to the rubbing after the application were evaluated. The evaluation methods of the respective items are as follows.

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

The cosmetics of each example (equal amount) were applied to the same area of the hand of the subject as the nail, to form a cosmetic coating film. Then, each coating film was rubbed by reciprocating a finger with a constant force, and the number of rubs (reciprocations) required until the coating film color was changed was evaluated.

A+: less than 3 times of reciprocation

A: 4-6 times of reciprocating

B: 7-10 times of reciprocating

C: more than 11 times of reciprocation

(2) Usability (stimulation effect of abrasive)

The evaluation was made by the feeling of roughness felt when the lips were rubbed against each other when the cosmetics of each example (equal amount) were applied to the lips and after the lips were applied.

A: strongly feel

B: slightly feel

C: not feel it

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

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

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

A: almost no change in hue was observed.

B: a weak change in hue was produced, but the hue of the entire cosmetic was not changed.

C: the color tone of the entire cosmetic changes.

(4) Color tone change caused by rubbing after coating

After the cosmetics (equivalent amount) of each example were applied to the lips, the lips were rubbed with a finger or rubbed against each other to change the impression of the color tone. The rubbing or rubbing was performed until the color tone change of each example of the cosmetics was completed.

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

A: the appearance impression of the lips varies greatly.

B: the appearance impression of the lips was hardly changed.

C: the appearance impression of the lips was completely unchanged.

In the above-mentioned "color change", the effect of improving the blood color feeling is obtained in the cosmetic having the evaluation result of "a+" or "a" of the color change when the warm color pigment such as the red pigment is used as "(a) the pigment-containing particles".

TABLE 2

*1, a step of; magicolor 103YP (Biogenic co., ltd.)

*2; sucrose (about 300 μm)

As is clear from the results shown in tables 1 and 2, the oily cosmetics (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 amount ratio [ (b)/(a) ] of (b) to (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 prescribed amount of the abrasive agent was blended, the abrasive effect (or massage effect) was high, and the pigment-containing particles (a) were easily crushed by rubbing (rubbing) after application, and color change was caused. 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 change could not be caused by rubbing (rubbing against each other) after the coating. In comparative example 1 in which the blending ratio [ (b)/(a) ] was 2.5, although it was possible to avoid crushing the particles (a) during the production, the particles were crushed at the time of applying the cosmetic because the blending ratio of the abrasive was too high, and a change in color tone due to rubbing (rubbing against each other) after the application was observed. Although the color tone change was observed in comparative example 3 in which no abrasive was blended, the number of rubs (rubbing against each other) required to obtain the color tone change was very large, and the use was not practical. In comparative example 4, in which pigment-containing particles were not blended, no change in color tone was caused even when the particles were rubbed (rubbed against each other).
