<p>Ultraviolet shielding agents capable of strongly shielding ultraviolet rays which are produced starting with natural substances and safe to the skin. These ultraviolet shielding agents contain, as the main components, an optionally decarboxylated coral sand powder and a wild silkworm cocoon shell powder. The coral sand and the wild silkworm cocoon shells, which are both natural materials capable of strongly shielding ultraviolet rays, can be safely employed.</p> |
