| TiO2 |
| Attenuation grade
TiO2 often
has a size of less than 100 nm.
Surface coated TiO2 with a
primary particle size of 15 nm and 35 nm are widely used for UV protection nowadays. TiO2 with a primary particle size of 10 nm is the latest development in TiO2 technology. They can be ground into finer particle and give higher UVB protection and better transparency. Attenuation grade TiO2 treated with crosspolymer treatment are now available for an easier dispersion in a wide variety of carriers. |

| ZnO |
| Because of the relatively lower reflective index, ZnO of a large size can be used in a formula without causing significant whitening. Nonetheless, ZnO of smaller size will give a better transparency, more UVB protection and, in general, more UVA protection when ZnO powder is used directly in a formula. |
