Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an oil-in-water emulsion cosmetic characterized by blending a hydrophobically treated powder and an oil-soluble resin, and the use of the cosmetic This provides a new cosmetic that is water resistant, oil resistant, and has secondary adhesion prevention effects.

[Prior Art] It has been desired to improve the longevity of cosmetics, especially makeup cosmetics and sunscreen cosmetics. To this end, cosmetics must have water resistance, oil resistance, and secondary adhesion prevention functions. Conventional emulsified cosmetics employ methods such as hydrophobicizing the pigments used, blending oil-soluble resins and water-soluble resins, or creating water-in-oil emulsified cosmetics. However, the long-lasting effect of makeup is insufficient, and a satisfactory effect has not been obtained. In addition, water-in-oil emulsion cosmetics are sticky due to oil and do not have a rough feel, making it difficult to obtain satisfactory usability.

[Problems to be Solved by the Invention] In view of the above circumstances, the present inventors have worked diligently to obtain a makeup emulsified cosmetic and a sunscreen emulsified cosmetic that are non-sticky, light, easy to use, and have good makeup retention. As a result of repeated research, we focused on a hydrophobically treated powder and an oil-soluble resin with high water resistance, oil resistance, and secondary adhesion prevention effect, and found that by blending these, we could solve this problem. The present invention has now been completed.

[Means for Solving the Problems] That is, the present invention is an oil-in-water emulsion cosmetic characterized by blending a hydrophobically treated powder and an oil-soluble resin.

Hereinafter, the configuration of the present invention will be explained in detail.

The powder used in the present invention may be any powder commonly used for cosmetics, such as titanium oxide, talc, kaolin, mica, calcium carbonate, calcium phosphate, zinc white, ultramarine, iron oxide titanium-mica pearl agent. Inorganic powders such as Red No. 202, Red No. 204, Yellow 401
It is an organic dye or pigment such as Blue No. 404. One or more of these may be selected and used depending on the required color tone and usability.

The hydrophobization treatment method referred to in the present invention includes treatment with silicone compounds such as methylhydrodiene polysiloxane, high viscosity silicone oil, and silicone 41 fat, treatment with surfactants such as anionic surfactants and cationic surfactants, treatment with nylon, polyester, etc. Treatments include treatments with polymeric compounds such as methyl methacrylate, polyethylene, Teflon, and polyamino acids, treatments with metal soaps, lipophilic waxes, polyhydric alcohol partial esters or complete esters, and the like. However, any method generally applicable to hydrophobizing treatment of powder may be used, and the method is not limited to these methods. Further, the hydrophobizing method for the powder may be carried out during the process of producing the cosmetic, or the powder may be blended after being hydrophobized in advance.

The blending amount of the hydrophobized powder used in the present invention is:
It is preferably 0.01 to 90% by weight based on the total amount of cosmetics.

Examples of the oil-soluble resin used in the present invention include fluororesins, silicone resins, hydrocarbon resins, and the like. Fluororesins include those that have pendant perfluoroalkyl groups in a straight hydrocarbon chain, such as perfluoroalkyl group-containing acrylic resins and perfluoroalkyl group-containing methacrylic resins, and those that have fluorocarbons in the main chain themselves, such as vinylidene bofluoride. Silicone resins include those that have both a hydrocarbon part and a fluorocarbon part in the main chain obtained by radical copolymerization of fluoroethylene and hydrocarbon vinyl ether.

As shown in Table 3, even if an oil-soluble resin is blended, powders that have not been hydrophobized are inferior in terms of water resistance and makeup discoloration due to sebum, but those that are blended with oil-soluble resins are inferior in terms of water resistance and makeup discoloration due to sebum. Cosmetics have excellent water resistance and are less likely to be transferred to clothing.
