<p>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)<SUB>x</SUB>-(hydrophile)<SUB>y</SUB>-(hydrophobe)<SUB>x</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)<SUB>y</SUB>-(hydrophobe)<SUB>x</SUB>-(hydrophile)<SUB>y</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.</p> |
