摘要： The phosphate- and polyacrylate-free powdered compositions which can be used in machines are based on surfactants, builders and fillers and contain 0.5 to 5% by weight of at least one enzyme from the group of hydrolases, preferably amylases, proteases and lipases. The builders preferably used are citric acid as well as NTA and EDTA, and the fillers preferably used are urea, cellulose, cellulose derivatives, sugars, sugar derivatives, alkali metal or magnesium sulphates and polyethylene glycols. It is also possible for foam-suppressant compounds from the group of paraffins, hydrophobic silica and bis-stearamides to be present.

摘要： Liquid cleaning preparations for hard surfaces containing (a) 0.5 to 40% by weight, preferably 5 to 20% by weight, of a surfactant or a surfactant mixture; (b) 0.01 to 1% by weight, preferably 0.05 to 0.5% by weight, of cleaning enhancer; (c) 0 to 6% by weight, preferably 1.0 to 6% by weight, of at least one organic and/or inorganic builder; and up to a total of 100% by wiehgt, based on the total weight, of water, and optionally, one or more of solubilizers (solvents, hydrotropes), preservatives, antimicrobial agents, viscosity regulators, pH regulators, perfumes, and dyes. Component (b) is a mixture of (i) at least one polyacrylamide and (ii) at least one highly polyethoxylated monofunctional or polyfunctional alkanol.

摘要： A process and apparatus for the care of contact lenses in which the process comprises supporting contact lenses on a lens holder within a treatment container provided with a motor-driven stirrer and introducing into the container a liquid, e.g., salt water, and a two-component system including (1) a first component providing a peroxide-compound cleaning and sterilizing solution, preferably in solid form and (2) a second solid component containing a catalyst or reducing agent providing a neutralizing solution wherein the second component dissolution is delayed until after the first component has acted on the contact lenses, and wherein the action of both components is effected under stirring; and the apparatus for practicing this process comprises a housing, a treatment compartment in the housing to hold a liquid, a lens holder removably supported in the compartment, a stirrer movably positioned in the housing which is separate from the lens holder and which extends into the compartment and drive means to move the stirrer and agitate the liquid in the compartment.
