Applicatio

Avobenzonum est syntheticum absorbens ultraviolaceum, quod bonum est absorbens ultraviolaceum UV-A (>320nm). UVA plena longitudine undae (320-400nm) impedire potest. Est efficax filtrum UVA lato spectro in oleo solubile. Cum aliis agentibus solaris UVB coniunctum, protectionem contra omnes radios UVA et UVB praebere potest, ne cancer cutis a luce causatus fiat.
