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: ?in-line-formulae description="In-line Formulae" end="lead"?HO-(hydrophobe)SUBx/SUB-(hydrophile)SUBy/SUB-(hydrophobe)SUBx/SUB-H?in-line-formulae description="In-line Formulae" end="tail"? ?in-line-formulae description="In-line Formulae" end="lead"?or?in-line-formulae description="In-line Formulae" end="tail"? ?in-line-formulae description="In-line Formulae" end="lead"?HO-(hydrophile)SUBy/SUB-(hydrophobe)SUBx/SUB-(hydrophile)SUBy/SUB-H?in-line-formulae description="In-line Formulae" end="tail"? 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° C.) of less than 1 mm.
