Description

  The present invention relates to an oil-in-water cosmetic for cosmetics, and more specifically, an alkyl acrylate / vinyl acetate copolymer emulsion, an alkyl acrylate copolymer emulsion having a specific glass transition temperature, a high melting point wax, It has a high curling effect and water resistance against tears and sweat, but when removing makeup, the cosmetic coating peels off in the form of a film. However, the present invention relates to an oil-in-water cosmetic for cosmetics that is easy to remove and easy to wash and also has a glossy appearance on the cosmetic coating film.

  Cosmetics for the eyelids have a cosmetic effect that makes the eyes beautifully stand out by curling the eyelids or making the eyelids thick and long. More recently, with the expansion of the vaginal cosmetics market and the diversification of makeup expressions, the glossiness of makeup coatings and makeup removal required to create a more attractive impression by making the glaze look lustrous In this case, there is a demand for new added value such as easy washing that can be easily removed without darkening around the eyes.

  In oil-in-water cosmetics, a technique for blending a large amount of wax, resin, and various film-forming agents or blending a fine dispersion of wax in order to impart a curling effect (see, for example, Patent Document 1) )was there. However, if a large amount of wax, resin or film-forming agent is added, the curling effect and water resistance are improved, but the glossiness of the cosmetic coating film is lost and it is difficult to remove the cosmetic coating film. There are many users who feel bothered by the trouble of dropping the eyes and the area around their eyes darkening when they are dropped.

  On the other hand, examples of the cosmetic film that can be easily removed include film-forming cosmetics that can be removed using warm water (see, for example, Patent Document 2) and easy-to-wash cosmetics that can be easily removed with water. Fees (for example, see Patent Documents 3 and 4) have been studied.

Japanese Patent No. 29898929 JP 2003-137732 A JP 2006-257052 A JP 2011-184375 A

  However, in the technique using a specific ionic surfactant for the expression of easy washing, under the circumstances where hot water cannot be used at the time of makeup removal, the cosmetic coating film is disintegrated without peeling off in the form of a film. In that respect, there was an inconvenience in cleanability. In addition, the technology using a water-soluble film forming agent such as polyvinyl alcohol is sufficiently satisfactory in terms of curling effect because the drying speed of the cosmetic film is slower than that of an oil-in-water cosmetic for cosmetics that does not contain it. However, there was room for further improvement in the development of oil-in-water cosmetics that satisfy both easy washing and curling effects.

  Therefore, in the present invention, since the drying speed is fast, the curling effect is high, and the makeup coating film is peeled off in the form of a film when removing makeup while maintaining water resistance against conventional tears and sweat. An object of the present invention is to provide an oil-in-water cosmetic for eyebrows that is easy to remove even with water without being darkened around the eyes and that is excellent in glossiness of a cosmetic coating film.

In such a situation, the present inventor has intensively studied, and as a result, blended a specific emulsion type film-forming agent and a high melting point wax, and did not substantially blend a water-soluble film-forming agent. The present inventors have found that an oil-in-water cosmetic for salmon to be solved can be obtained, and have completed the present invention.
That is, the present invention includes the following components (A) to (C);
(A) Alkyl acrylate / vinyl acetate copolymer emulsion (B) Alkyl acrylate copolymer emulsion having a glass transition temperature of 5 to 15 ° C. (C) A wax having a melting point of 80 to 110 ° C. It is an oil-in-water cosmetic for cosmetics characterized in that the amount of the functional film forming agent is less than 0.1% by mass.

  The oil-in-water cosmetic for cosmetics of the present invention has a high curl effect and water resistance against tears and sweat, but when the makeup is removed, the cosmetic coating peels off in the form of a film, Is an oil-in-water cosmetic for cosmetics that has excellent easy-to-wash properties that can be easily removed even with water without darkening, and also has a glossy appearance on the decorative coating film.

Hereinafter, the present invention will be described in detail.
The film of the component (A) alkyl acrylate / vinyl acetate copolymer emulsion used in the oil-in-water cosmetic for cosmetics of the present invention is excellent in the gloss of the paint film, and is coated by being partially swollen by water. Since it has the property of peeling into a film while maintaining the continuity of the film, the component (A) is blended in order to improve the ease of washing with water and the glossiness of the decorative coating film. An alkyl acrylate / vinyl acetate copolymer emulsion is a resin obtained by emulsion polymerization of one or more alkyl acrylate monomers and / or alkyl methacrylate monomers and a vinyl acetate monomer as main components. These alkyl groups may be one type having 1 to 12 carbon atoms or two or more types. Any component may be used as long as it is used in cosmetics as the component (A), and any of them can be used. The polymer component is an INCI name (International Nomenclature Cosmetic Labeling Names), ACRYLATES / It is listed as VA COPOLYMER.

  Although the compounding quantity of the component (A) in this invention is not specifically limited, 2-12 mass% (henceforth only "%") in all cosmetics in conversion of solid content is preferable, More preferably, 4-8 %. Within this range, a satisfactory product can be obtained in terms of easy washing and glossiness of the decorative coating without impairing water resistance.

  The film of the alkyl acrylate copolymer emulsion of component (B) used in the oil-in-water type cosmetic for cosmetics of the present invention exhibits a curl effect because it has sufficient hardness, and from the high film strength Excellent water resistance and glossiness of the decorative film. The component (B) alkyl acrylate copolymer emulsion is mainly composed of two or more kinds of acrylic acid, methacrylic acid, or alkyl esters thereof, and usually a resin obtained by emulsion polymerization of these and water These alkyl groups may be one type having 1 to 12 carbon atoms or two or more types. The polymer component is listed under the INCI name as ACRYLATES COPOLYMER and AMMONIUM ACRYLATES COPOLYMER. Among these, an ammonium salt emulsion of an alkyl (meth) acrylate copolymer is preferable because of excellent curling effect. As a commercial item, vinylol 1086WP (made by Daido Kasei Kogyo Co., Ltd.) etc. can be illustrated preferably.

  Moreover, among the alkyl acrylate copolymer emulsions used in the cosmetics, those having a glass transition temperature (Tg) of 5 to 15 ° C. can be used as the component (B). When the glass transition temperature is lower than 5 ° C., the film becomes too soft and sufficient curling effect and water resistance are not exhibited. On the other hand, if the glass transition temperature exceeds 15 ° C., the film becomes brittle and the glossiness of the decorative coating film is reduced.

In this specification, the glass transition temperature (Tg) means the glass transition temperature of the copolymer, and can be obtained from the Fox formula shown in the following calculation formula and converted to Celsius.
1 / Tg = Σ (Wi / Tgi)
In the above formula, Tg represents the glass transition temperature (K) of the desired copolymer, Wi represents the mass fraction of each monomer, and Tgi represents the glass transition temperature (K) of the homopolymer of the corresponding monomer. . The Tg of the homopolymer may be a value described in a publication such as “POLYMER HANDBOOK” (4th edition; issued by John Wiley & Sons, Inc.).

  Although the compounding quantity of the component (B) in this invention is not specifically limited, 4-16% in all cosmetics is preferable in conversion of solid content, More preferably, it is 6-12%. If it is this range, what is satisfactory in the point of a curl effect, water resistance, and the glossiness of a cosmetic coating film will be obtained, without impairing easy water washing property.

  Moreover, in this invention, it is preferable that the mass ratio in conversion of solid content of a component (A) and a component (B) is (A) :( B) = 3: 1 to 1: 2. If it is this range, both water resistance and easy water washing property can be satisfy | filled, and the effect of this invention can be exhibited to the maximum.

  The wax of component (C) used in the oil-in-water cosmetic for cosmetics of the present invention is blended for the purpose of improving water resistance while exhibiting a high curling effect due to its excellent hardness. Of the waxes that are usually blended in cosmetics, there is no particular limitation as long as it has a melting point of 80 ° C to 110 ° C. For example, carnauba wax, candelilla wax, rice wax, fructooligosaccharide fatty acid ester, ceresin wax , Microcrystalline wax, polyethylene wax, ethylene propylene copolymer, Fischer-Tropsch wax, ozokerite wax, paraffin wax and the like. Moreover, these can be used 1 type or in combination of 2 or more types as needed.

  Although the compounding quantity of the component (C) in this invention is not specifically limited, 0.1 to 10% is preferable and 3 to 8% is more preferable. If it is this range, what is satisfactory in the point of a curl effect and water resistance will be obtained, without impairing easy water washing property and the glossiness of a cosmetic coating film.

  Further, in the present invention, the water-soluble film-forming agent has a slow drying speed, and the wrinkles are lowered by the weight before the vaginal cosmetics are completely dried. Since stickiness occurs in the coating film, the blending amount is desirably less than 0.1% (including 0%). The water-soluble film forming agent is a water-soluble polymer that forms a film after drying, and examples thereof include polyvinyl alcohol, polyvinyl pyrrolidone, vinyl pyrrolidone / vinyl acetate copolymer, and the like.
