Enhanced photoactivity of semiconductors and/or sunscreens
View Patent ↗A composition comprising a physical sunscreen, one or more adjuvants, and a carrier oil is provided. The composition also includes at least one of a compound having multiple phenyl groups, a film former or dispersant, and a silicone surfactant. The composition may also include an organic sunscreen.
