    摘要： Methods, compositions, and devices for alleviating the problems of toxic discharge of aldehydes present in waste streams are disclosed. The methods relate to reducing neutralized aldehydes wherein the neutalized aldehydes are formed by treating aldehydes with amino acids and thereinafter are reduced. These reduced, neutralized aldehydes do not revert back to toxic aldehydes, but form amino acids and thus allow waste containing aldehyde to be more environmentally safely disposed.

    摘要： Hydrogel contact lenses that are derived from a polymerizable composition including at least one hydrophilic monomer and at least one phosphine-containing component are described. The hydrogel of the contact lenses can be a silicone hydrogel or a non-silicone hydrogel. Use of polymerizable compositions comprising a phosphine-containing component can be cured under both inert and air atmospheres, and can be used to form hydrogel contact lenses having improved shape retention properties, having improved resistance to discoloration. Batches of hydrogel contact lenses and methods of making hydrogel contact lenses are also described.

    摘要： The effectiveness of an oxidative sterilization process is determined by exposing a substrate having a known amount of a primary amine or aldehyde indicator chemical to an oxidative germicide. The oxidative germicide reacts with the indicator chemical. The amount of indicator chemical remaining after exposure to the germicide is determined by reacting the indicator chemical with a dye precursor chemical to form a colored product. The amount of indicator chemical remaining on the substrate is determined from the intensity of the color of the colored product. The amount of indicator chemical remaining on the substrate is a measure of the effectiveness of the germicidal treatment. The dye precursor is an aldehyde when the indicator chemical is a primary amine and a primary amine when the indicator chemical is an aldehyde. An integrator for determining the effectiveness of the germicidal process includes a substrate and an indicator chemical, where the indicator chemical is a primary amine or an aldehyde.
