Abstract
The present invention provides an emulsion cosmetic that forms a coating film having excellent water resistance and abrasion resistance, and also has formulation stability and good usability. An emulsified cosmetic comprising an oil phase comprising (a) a water-soluble cationic polymer and an aqueous phase comprising (b) a water-soluble anionic polymer.
Description
Technical Field
The present invention relates to an emulsified cosmetic, and more particularly, to an emulsified cosmetic containing an oil phase containing a water-soluble cationic polymer and an aqueous phase containing a water-soluble anionic polymer, and a method for producing the same.
Background
In recent years, demand for functional cosmetics has been increasing, and various functional cosmetics have been developed according to the purpose of use. There are many products which have been made functional by forming a coating film on the skin or hair, for example, products which impart a function of preventing this phenomenon during the daytime to hair which curls when humidity is high (japanese text: うねり), and cosmetics which have a high ultraviolet protection capability in foundation and sunscreen to protect the skin from UVA (long-wavelength ultraviolet rays having a wavelength of 320 to 400 nm) and UVB (medium-wavelength ultraviolet rays having a wavelength of 290 to 320 nm).
However, it is known that a coating film formed when a cosmetic is applied comes off with the lapse of time, and the functionality is degraded. In particular, when subjected to physical rubbing, sweating, bathing in a swimming pool or the sea, or the like, the coating film is more significantly peeled off, and therefore, development of a cosmetic with less deterioration in functionality has been desired.
Therefore, the following techniques have been developed: a technique of imparting high water resistance by selecting silicic anhydride as a gelling agent in order to cure an oily component containing fine particulate zinc oxide subjected to hydrophobic treatment and an oil-soluble ultraviolet absorber into a coating film (for example, jp 2018-76313 a); a technique of dispersing a particulate metal oxide coated with a specific compound on the surface thereof in an oil phase together with a specific partially crosslinked organopolysiloxane polymer and polyhydroxystearic acid, and combining the dispersion with a (sodium acrylate/sodium acryloyldimethyltaurate) copolymer to form an oil-in-water emulsion cosmetic, thereby forming a soft and uniform cosmetic film to impart water resistance (for example, japanese patent application laid-open No. 2017-137300); a technique in which a stable oil-in-water emulsion composition is obtained by using a polyion complex formed by a specific combination of a cationic polymer and an anionic polymer as an emulsifier, various oil components can be blended, and the obtained oil-in-water emulsion exhibits excellent water resistance (for example, japanese patent application laid-open No. 2011-32249).
Disclosure of Invention
However, the above techniques have problems of poor touch as a cosmetic and insufficient water resistance and rubbing resistance.
Accordingly, an object of the present invention is to provide an emulsion cosmetic which forms a coating film having excellent water resistance and abrasion resistance, and further has formulation stability and good usability.
In view of the above, the present inventors have tried to incorporate a cationic polymer and an anionic polymer in the same phase, and then have found that there are problems as follows: when the cationic polymer and the anionic polymer are complexed in the same phase, coagulation occurs and the formulation cannot be made. As a result of the diligent study, the following findings were found: the present inventors have found that the oil phase contains a water-soluble cationic polymer and the water phase contains a water-soluble anionic polymer, whereby the oil phase has stability as a preparation, and further, the water-soluble cationic polymer and the water-soluble anionic polymer aggregate to form a firm coating film during coating, whereby the coating film has improved water resistance and abrasion resistance and has excellent usability, and thus the present invention has been completed.
Namely, the present invention is as follows.
(1) An emulsified cosmetic comprising an oil phase comprising (a) a water-soluble cationic polymer and an aqueous phase comprising (b) a water-soluble anionic polymer.
(2) The emulsion cosmetic according to (1), wherein the emulsion cosmetic contains (c) at least one of a metal oxide and a plate-like powder.
(3) The emulsion cosmetic according to (1) or (2), wherein the emulsion cosmetic contains (d) stearylinulin.
(4) The emulsion cosmetic according to any one of (1) to (3), wherein the content mass ratio (a)/(b) of the water-soluble cationic polymer (a) to the water-soluble anionic polymer (b) is 0.05 to 20.
(5) The emulsion cosmetic according to any one of (1) to (4), wherein the water-soluble cationic polymer (a) is one or more selected from the group consisting of dimethyldiallylammonium chloride/acrylamide copolymer, 2-hydroxy-3- (trimethylammonio) propylpolyethylene oxide cellulose ether chloride (O- [ 2- ヒドロキシ -3- (トリメチルアンモニオ) プロピル ] ヒドロキシ エ チ ル セ ル ロ ー ス in the Japanese text) and guar hydroxypropyltrimonium chloride (O- [ 2- ヒドロキシ -3- (トリメチルアンモニオ) プロピル ] グァーガム in the Japanese text).
(6) The emulsion cosmetic according to any one of (1) to (5), wherein the water-soluble anionic polymer (b) is one or more selected from the group consisting of a carboxyvinyl polymer, an acrylic acid/alkyl methacrylate copolymer and a sodium acrylate/sodium acryloyldimethyltaurate copolymer.
(7) The emulsion cosmetic according to any one of (1) to (6), wherein the emulsion cosmetic is an oil-in-water emulsion cosmetic.
(8) The emulsion cosmetic according to any one of (1) to (7), wherein the emulsion cosmetic contains (e) a benzalmalonate polysiloxane (Japanese text: ジメチコジエチルベンザルマロネート).
(9) A method for producing an emulsified cosmetic, wherein the emulsified cosmetic comprises an oil phase and an aqueous phase, the oil phase comprising (a) a water-soluble cationic polymer, and the aqueous phase comprising (b) a water-soluble anionic polymer.

In the present invention, it is preferable that inulin fatty acid ester (component (d) be further contained (hereinafter, also simply referred to as component (d)). By containing the inulin fatty acid ester, the adhesion to the skin is improved, thereby further improving the water resistance, the rub resistance, the use properties (particularly, no slimy feeling), and the formulation stability. The component (d) may be incorporated in either of the aqueous phase and the oil phase, and is particularly preferably incorporated in the oil phase. By blending in an oil layer, water resistance, abrasion resistance, usability (particularly, no slimy feel) and formulation stability are further improved by the thickening effect of the oil phase.

The content of the component (d) in the present invention is not particularly limited, but is preferably 0.1 to 10%, and particularly preferably 1 to 5% in the emulsion cosmetic. When the amount is within this range, the dispersibility of (a) in the oil phase is improved, and when a powder (for example, component (c)) is blended, the dispersibility of the powder is improved, and a preparation having excellent water resistance, abrasion resistance and stability can be provided.
In the present invention, it is preferable that the silicone resin composition further comprises component (e), a benzalmalonate. It is known that INCI (International NOMENCLATURE of COSMETIC INGREDIENTS, International name of COSMETIC INGREDIENTS) of the benzalmalonate polysiloxane (component (e) used in the present invention is represented by polysiloxane-15, which is an organosilicon derivative in which about 7.5% of dimethylpolysiloxane having a chain length of about 60 is substituted with two substituents, has a high ultraviolet ray-shielding ability by itself, and increases the values of SPA and PA (boost effect) by a synergistic effect with other ultraviolet ray-shielding agents. In the present invention, the component (e) is preferably contained in the oil phase, and functions also as a component for improving the water resistance and rubbing resistance of the coating film, and contributes to the stability of the cosmetic. As a commercially available product, PARSOL SLX (manufactured by DSM Nutrition Products Co., Ltd.) can be exemplified.
The content of the component (e) in the present invention is not particularly limited, but is preferably 0.1 to 10%, and particularly preferably 1 to 5% in the emulsion cosmetic. Within this range, not only a high ultraviolet shielding effect can be obtained, but also the stability of the preparation is good, and therefore, it is preferable.

Further, the formulation of the cosmetic of the present invention, such as a water-in-oil emulsion system, an oil-in-water emulsion system and the like, is not particularly limited, but an oil-in-water emulsion system is preferable because improvement of water resistance is required in the oil-in-water emulsion type having lower water resistance from the viewpoint of usability by water wetting. That is, a preferred embodiment of the present invention is an oil-in-water type emulsion cosmetic. The cosmetic composition can be applied in the form of various cosmetics such as skin care cosmetics such as milky lotion, cream, lotion, lip gloss, sunscreen cream, foundation, makeup cosmetics such as foundation, blush, eye shadow, lipstick, lip gloss, scalp or hair cosmetics such as hair conditioner, hair cream, hair conditioner, etc.
In addition, one embodiment of the present invention is an emulsified sunscreen cosmetic. In addition, another embodiment of the present invention further includes an ultraviolet absorber. By improving the water resistance and rubbing resistance of the cosmetic coating film, a sunscreen agent having a high ultraviolet ray shielding ability and in which the ultraviolet ray absorber is not easily detached by sweat or water can be produced. The ultraviolet absorber may be used without any particular limitation as long as it is an ultraviolet absorber generally used in sunscreen cosmetics. Examples of the ultraviolet absorber include ethylhexyl methoxycinnamate, hexyl 2- [4- (diethylamino) -2-hydroxybenzoyl ] benzoate, ethyl p-aminobenzoate, benzophenone-1, benzophenone-3, benzophenone-6, benzophenone-9, 2,4, 6-tris [4- (2-ethylhexyloxycarbonyl) anilino ] -1,3, 5-triazine, dioctylbutanoylaminetrione, 4-tert-butyl-4' -methoxy-dibenzoylmethane, 2, 4-bis { [4- (2-ethyl-hexyloxy) -2-hydroxy ] -phenyl } -6- (4-methoxyphenyl) - (1,3,5) -triazine, 2' -methylenebis [6- (2H-benzotriazol-2-yl) -4- (1,1,3, 3-tetramethylbutyl) phenol ], polysiloxane-15, and the like, and one or more of them may be used. Of these, ethylhexyl methoxycinnamate, hexyl 2- [4- (diethylamino) -2-hydroxybenzoyl ] benzoate, 4-tert-butyl-4' -methoxy-dibenzoylmethane, 2, 4-bis { [4- (2-ethyl-hexyloxy) -2-hydroxy ] -phenyl } -6- (4-methoxyphenyl) - (1,3,5) -triazine, polysiloxane-15, more preferably ethylhexyl methoxycinnamate, hexyl 2- [4- (diethylamino) -2-hydroxybenzoyl ] benzoate, 2, 4-bis { [4- (2-ethyl-hexyloxy) -2-hydroxy ] -phenyl } -6- (4-methoxyphenyl) - (1,3,5) -triazine. The content of the ultraviolet absorber is, for example, 1 to 10% in the emulsion cosmetic.
Further, the method of using the emulsion cosmetic of the present invention includes a method of using it with hands, fingers, or cotton, a method of using it by impregnating it with a nonwoven fabric, a method of using it as a spray or an aerosol, and the like.
