Polyol solvents were used to extract Camellia oleifera Abel dregs and sunscreen properties of the extracts were examined in the present paper. The effects of extracts obtained with water and ethanol were compared. This study found that polyols were more efficient at extracting flavonoid glycosides, triterpenoid glycosides, and other polyphenols in the C. oleifera Abel dregs, resulting in a more efficient sunscreen. The polyphenols in the extract had peak absorbance at wavelengths of 254, 280, and 329 nm, the triterpenoid glycosides had a peak at 200–240 nm and the flavonoid glycosides showed a broad range of absorption (at 230–400 nm). The extract obtained with polyol solvent had strong absorption at wavelengths of 200–400 nm. The interaction of the polyol extracts with organic UV-absorbers or inorganic sunscreen agents showed synergic effects and the extract can significantly improve the sunscreen effect of organic UV-absorbers or inorganic sunscreen agents. Therefore, this extract can decrease the amount of organic UV-absorbers and inorganic sunscreen agents used and can increase protection against UVA and UVB. It can be used in maintenance and sunscreen products.
