Abstract:
The present invention provides a sunscreen cosmetic comprising, relative to the total amount of the sunscreen cosmetic, 10-90 wt % of agar microgel (wherein the agar content in the agar microgel is 0.4-1 wt %) and 0.1-5 wt % of a water soluble ultraviolet absorbent.It was necessary to blend in an organic ultraviolet absorbent and such to give sunscreen cosmetics a high SPF value. However, there was a problem in that it was hard for a water soluble ultraviolet absorbent in the formulation to achieve the expected SPF function. Also, sunscreen cosmetics are particularly desired to give a freshing texture upon use.In view of the fact that a high blend ratio of an oil soluble ultraviolet absorbent inhibits the freshing texture upon use, the object of the present invention is to provide a sunscreen cosmetic that achieves a high SPF value and a freshing texture upon use by mainly blending in a water soluble ultraviolet absorbent.
