APPLICATIONS |
||
| Benzophenone derivatives are used as an ingredient of sunscreening agent to absorb the UV radiation and to prevent the formation of free radicals. The principal structure is aromatic molecules conjugated with carbonyl group. Depending on substituents on benzophenone molecule, the pattern of the UV absorption applications can be selected. They are used extensively in plastics and cosmetics. 4,4'-Dihydroxybenzophenone has two hydroxyl substituents in the two para positions. | ||
