Detailed Analysis
Xanthopterin is a pteridine-class pigment naturally found in butterfly wings, wasp cuticles, and some microorganisms. It produces a yellow color and may have minor UV-absorbing properties. While naturally occurring, limited cosmetic safety data exists. Pteridines can be photosensitive, which may be a consideration in sun-exposed formulations.
