Said cosmetic exhibits not only the refreshed feeling on use without unfavorable stickiness after application, but also proper oily feeling. There are obtained good affinity to the skin, little occurrence of creasing and/or make-up deterioration, no oily sheen upon the elapse of long periods of time after application, and little irritation to the skin and excellent safety to the skin. In addition, the present cosmetic is able to be removed with commercially available cleansing agents. Moreover, the dispersibility of pigments as well as the storage stability is excellent. A water-in-oil type emulsified cosmetic comprising (A) 10 to 60 parts by mass of a diester represented by the following formula (I): (B) 1.0 to 11 parts by mass of a nonionic surfactant, (C) 0.3 to 11 parts by mass of an oil-soluble and/or water-soluble thickener, (D) 0.1 to 30 parts by mass of fine particles, and (E) 5.0 to 75 parts by mass of water, wherein the total of (A), (B), (C), (D) and (E) is 100 parts by mass. ## Claims ### Claim 1 A water-in-oil emulsified cosmetic comprising (A) 10 to 60 parts by mass of a diester represented by the following formula (I): (B) 1.0 to 11 parts by mass of a nonionic surfactant, (C) 0.3 to 11 parts by mass of an oil-soluble and/or water-soluble thickener, (D) 0.1 to 30 parts by mass of fine particles, and (E) 5.0 to 75 parts by mass of water, wherein the total of (A), (B), (C), (D) and (E) is 100 parts by mass. ### Claim 2 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the diester represented by the formula (I) is 12 to 55 parts by mass. ### Claim 3 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the diester represented by the formula (I) is 14 to 50 parts by mass. ### Claim 4 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the nonionic surfactant (B) is 1.1 to 9.8 parts by mass. ### Claim 5 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the nonionic surfactant (B) is 1.2 to 9.6 parts by mass ### Claim 6 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the oil-soluble and/or water-soluble thickener (C) is 0.4 to 9.8 parts by mass. ### Claim 7 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the oil-soluble and/or water-soluble thickener (C) is 0.5 to 9.6 parts by mass. ### Claim 8 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the fine particles (D) is 0.2 to 28 parts by mass. ### Claim 9 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of the fine particles (D) is 0.3 to 26 parts by mass. ### Claim 10 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of water (E) is 10 to 68 parts by mass. ### Claim 11 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the amount of water (E) is 15 to 66 parts by mass. ### Claim 12 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the nonionic surfactant (B) is at least one selected from the group consisting of sorbitan monoisostearate, lipophilic glycerin monostearate, glyceryl stearate (SE), sorbitan sesquiisostearate, polyglyceryl-2 isostearate, polyglyceryl-2 diisostearate, polyglyceryl-2 triisostearate and sorbitan oleate. ### Claim 13 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the nonionic surfactant (B) is at least one selected from the group consisting of sorbitan monoisostearate, lipophilic glycerin monostearate, sorbitan sesquiisostearate, polyglyceryl-2 isostearate and sorbitan oleate. ### Claim 14 (depends on 1) The water-in-oil emulsified cosmetic according to claim 1, wherein the cosmetic is a make-up or sun-care cosmetic. ### Claim 15 (depends on 1) A method of making-up a person comprising applying to the person a cosmetic according to claim 1.
