While commercially available suncare products are effective at absorbing ultraviolet (UV)-light, recent studies indicate systemic toxicities associated with many traditional chemical and physical UV-filters. We demonstrate the application of xanthommatin, a biochrome present in arthropods and cephalopods, as an alternative chemical UV-filter that is cytocompatible while maintaining its photostability and photoprotective properties.
COSMETIC AND DERMATOLOGICAL COMPOSITIONS
-
Paragraph 00126-00128, (2019/04/16)
Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.
Oxidation of 3-Hydroxykynurenine. An EPR investigation
Bolognese, Adele,Bonomo, Raffaele P.,Chillemi, Rosa,Sciuto, Sebastiano
, p. 2207 - 2208 (2007/10/02)
A weak alkaline solution of 3-hydroxykynurenine was oxidized using potassium ferricyanide.A stable epr signal was recorded, probably arising from a phenoxazine intermediate.A plausible radical mechanism for this reaction is presented.
