Abstract: To provide a transparent solid composition having a high ultraviolet ray blocking effect, as well as superior moldability and stability. A transparent solid composition includes: (a) 12-hydroxystearic acid in an amount within a range from 1 to 15% by mass; (b) an oil having a refractive index within a range from 1.5 to 1.7; (c) an oil having a refractive index of 1.3 or greater and less than 1.5; and (d) one type or two or more types of an ultraviolet ray absorbing agent in an amount within a range from 5 to 50% by mass. The refractive index of the transparent solid composition is within a range from 1.47 to 1.55.
