Ultraviolet rays contained in sunlight perform medically various useful functions and also help skin health when an appropriate amount is irradiated to the exposed skin surface of the human body. Damage and, in some cases, side effects that cause diseases such as skin cancer. In order to protect human skin from the damage of ultraviolet rays, recently applied creams or lotion-type sunscreens containing pharmacological ingredients exhibiting the ability to block ultraviolet rays when applied to the skin. Organic and inorganic inorganic sunscreen agents include UV-blocking materials, titanium dioxide dispersions for inorganic systems, and octylmethoxycinnamate, butylmethoxydibenzoylmethane, octyltrizone, and oxybenzone. It is used. Conventional sunscreens based on these active ingredients are usually water-in-oil type with oil on the outside and water dispersed therein in order to prevent the washing away by sweat after application to the skin. W / O type) lotion or cream. However, the W / O type sunscreen has excellent durability against sweat, but has a disadvantage in that the feeling of use of the product is heavy, sticky, and slippery. In addition, lotions and creams are stored in a certain container, so it is inconvenient to carry, and when applied to the skin by applying a certain amount to the fingers or the like, after applying to the skin by inorganic pigments contained in most formulations, a white cloud phenomenon occurs for a certain time. In addition, it takes a relatively long time to get rid of it, and there is a possibility that the lotion or cream ingredient remaining on the finger after use may become sticky due to sweating, and the feeling of use is greatly reduced. Moreover, since these sunscreens are mainly used during the summer months, if only a part of the sunscreens in the large containers are used, the remaining amount must be stored for almost one year until the next summer, which is inconvenient and uneconomical. There is also the problem of deterioration.

Therefore, the present inventors have developed a tissue-type sunscreen obtained by absorbing a sunscreen composition having a short skin absorption time into a tissue as a result of research on developing a sunscreen agent that is easy to carry and easy to apply to the skin and has excellent usability. The invention was completed.
