摘要：
A method for forming a benzophenone derivative product that resistant to absorption by living tissue that includes binding a benzophenone-containing compound with an oxide-containing particle by acid-catalyzed condensation or Friedel-Crafts acetylation to provide a benzophenone derivative having a microscale size. The benzophenone derivative can then be mixed into a lotion. The microscale size of the benzophenone derivative obstructs absorption by cell tissue. The benzophenone derivative may be an oxybenzone derivative.
