Patent number: 5532029Abstract: This invention relates to novel compositions containing temporary visual indicators and methods for using these compositions. Specifically, this invention relates to a sunscreen composition containing an indicator that is visible when the substance is applied to the skin, but becomes invisible shortly after application. The continued presence of the indicator allows the indicator to be reactivated temporarily to the visible form so that a user can verify the presence of the sunscreen. The visible indicator ensures that the sunscreen is applied evenly and completely to the area to be protected, but becomes invisible so as not to interfere with the action of the sunscreen or discolor the skin.Type: GrantFiled: February 14, 1995Date of Patent: July 2, 1996Inventors: Ronnie S. Fuerst, Richard Melker, Christopher D. Batich
