Abstract:
Forty-three certified food, drug and cosmetic colours presently allowed by the Food and Drug Administration were screened for chemical photosensitizing activity by using photogeneration of singlet molecular oxygen as an evaluation parameter. Singlet oxygen production was estimated by electron paramagnetic resonance spectrometry by monitoring the conversion of 2,2,6,6-tetramethyl-4-piperidone to the N -oxide radical. Only xanthene- type dyes substituted with bromine or iodine (FD&C Red No. 3, D&C Red Nos. 21, 22, 27 and 28, and D&C Orange Nos. 5, 10 and 11) were found to generate singlet oxygen. © 1988 Taylor & Francis Group, LLC.
