Provided is a sun protection composition including an UV absorber and a plurality of porous titanium dioxide microsphere. The UV absorber absorbs at least one of UVA wavelength and UVB wavelength. A particle size of the porous titanium dioxide microsphere is between 100 nm and 300 nm, and that may scatter a light of a wavelength range between 200 nm and 400 nm. A cosmetic and a fabric containing the sun protection composition also may scatter a light of a wavelength range between 200 nm and 400 nm. And the UV protection of the cosmetic and the fabric is enhanced by the sun protection composition.一種防曬組成物包括紫外光吸收劑以及多數個多孔性二氧化鈦微球。紫外光吸收劑吸收UVA、UVB之至少其中之一波段的光線。多孔性二氧化鈦微球的粒徑為100nm至300nm，其可散射波長範圍為200nm至400nm的光線。而包含此防曬組成物的化妝品以及織品，亦可散射波長範圍為200nm至400nm的光線，以提升上述化妝品以及織品的紫外光防護能力。
