In case anyone is interested......In order to ensure the safety of chemicals and ingredients in formulations, a screening test exists and is regulatorily accepted - 3T3 NRU Phototoxicity test. The 3T3 NRU PT is an in vitro toxicity test that can determine the phototoxic potential of test substances using fibroblasts derived from a mouse tumor cell line (3T3 Balb/C). A monolayer of 3T3 cells are dosed with a test substance and then irradiated with simulated sunlight and viability is measured via MTT uptake.
