Raspberry seed oil offers natural UVA + UVB protection similar to titanium dioxide with a 28-50 SPF protection factor against UVB rays and 8 SPF against UVA rays. A study was conducted in 2000 on the properties of oil extracted from raspberry seeds. Raspberry seed oil showed absorbance in the UV-B and UV-C ranges with potential for use as a broad spectrum UV protectant. Oil yield from the seed was 10.7%. Physicochemical properties of the oil include: saponi®cation number 191;
