This molecule also displays photophysical properties that vary greatly from benzophenone, possessing both lower energy absorption and emission bands. |
Typical examples are aromatic ketones such as acetophenone, benzophenone, benzoin ethyl ether and benzyl dimethyl ketal. |
The main chemistries of UV absorbers are hydroxy benzophenone, hydroxy phenyl benzotriazoles, and hydroxy phenyl triazines. |
Many sunscreen products contain benzophenone or one of its derivatives. |
