| Abstract: | Backscattered electron (BSE) imaging was used to study ultrafine TiO2 crystals distribution in a test cream. The cream was fast frozen, cryofractured and observed uncoated at low temperature. The BSE detector was a microchannel plate. The results demonstrate that up-to-date photoprotective preparations can be investigated by this technique. |
