COMPOSITIONS AND METHODS FOR CLEANING CONTACT LENSES

摘要

A composition for disinfecting a contact lens comprising an effective disinfecting amount of hydrogen peroxide and a surfactant comprising a copolymer of hydrophobe and hydrophile blocks the structure: HO - (hydrophobe)x - (hydrophile)y - (hydrophobe)x or HO - (hydrophile)y - (hydrophobe)x - (hydrophile)y - H where x and y are integers reflecting the respective hydrophile and hydrophobe blocks of said copolymer; and the hydrophile component of the block copolymer constitutes less than 50 weight percent of the block copolymer. The block copolymer has a Ross-Miles foam height (ASTM designation D-1173-53; 0.1%, at 50 DEG C) of less than 1mm.
