Embodiment 5

[0045] In Example 5, the W / O type emulsion foundation cosmetic composition in Reference Example 1 was impregnated into a porous polyurethane foam with a hardness of 40 (measured with an ASKER hardness tester (F type)), and then coated with a cosmetic The composition was applied to the skin using an NBR puff. In Comparative Example 5 and Comparative Example 6, the composition in Reference Example 1 was placed in a tube container or a press container, and then applied to the skin by hand. The skin temperature-lowering effect was determined by measuring the change in skin stabilization after each composition was applied to the skin. In Example 6, the O / W type emulsion foundation cosmetic composition in Reference Example 3 was impregnated into a porous polyurethane foam with a hardness of 40 (measured with an ASKER hardness tester (F type)), and then coated with a cosmetic The composition was applied to the skin using an NBR puff. In Comparative Example 7 and Comparative Example...

Abstract

The present invention relates to cosmetics containing a W / O or O / W UV-blocking composition with low viscosity which are packaged in a cosmetic container. More specifically, UV-blocking cosmetics are prepared by the steps of: impregnating the W / O or O / W UV-blocking composition with low viscosity in urethane foam; formulating the composition impregnated in urethane foam in a compact form; and packaging the compact formulation in a cosmetic container. Accordingly, the UV-blocking cosmetics have a cooling effect and can improve portability and convenience for users.

Description

technical field [0001] The present invention relates to a UV barrier product prepared by impregnating a low viscosity UV barrier W / O (water-in-oil) or O / W (oil-in-water) emulsion cosmetic composition into porous polyurethane foam, Thus allowing the active ingredients of the composition to be effectively applied to the skin, and convenient to use and carry. Background technique [0002] Exposure to ultraviolet rays from the sun is the main cause of skin erythema, edema, freckles or skin cancer. Recently, various diseases caused by ultraviolet rays have been actively researched. [0003] Generally speaking, ultraviolet rays are divided into UV-C (240-280nm), UV-B (280-320nm) and UV-A (320-400nm) according to wavelength. Due to being absorbed by the ozone layer, UV-C radiation cannot reach the earth's surface; while UV-B can penetrate the epidermis and cause erythema, freckles, edema, etc. UV-A is known to penetrate into the dermis of the skin causing skin aging and skin irr...
