Abstract: This invention is directed to an aqueous composition and methods for clean lipid deposits on contact lenses. In particular, a combination of non-ionic surfactants, branched and/or straight poly(ethylene oxide-propylene oxide) (PEO-PPO) block copolymers having HLB value greater than or equal to 18, with an additional straight poly(ethylene oxide-propylene oxide) (PEO-PPO) block copolymers having HLB value less than or equal to 15, has been found to improve the lipid cleaning properties of an aqueous composition for contact lenses and prevent the overgrowth of harmful bacteria, yeast and molds without adversely affecting the comfort or safety in terms of the level of toxicity to eye tissue.

Abstract: This invention is directed to a method of treating a silicone hydrogel lens to cleaning lipid deposits thereon. The method comprises administering to the contact lens a solution comprising a first straight chain polyether surfactant. The first straight chain polyether surfactant has an HLB value that is a minimum of about 18. The second straight chain polyether surfactant has an HLB value that is a minimum of about 12 and a maximum of about 18. The second surfactant is present in an amount effective to improve the ability to remove lipids from a silicone hydrogel lens.

Abstract: This invention is directed to an aqueous composition and methods for cleaning lipid deposits and/or prevention of lipid deposition on contact lenses. In particular, a combination of non-ionic surfactants, straight chain poly(ethylene oxide-propylene oxide-ethylene oxide) (PEO—PPO—PEO) block copolymers having HLB value greater than or equal to 18, with an additional straight chain poly(ethylene oxide-propylene oxide-ethylene oxide) (PEO—PPO—PEO) block copolymer having an HLB value less than or equal to 11, has been found to improve the lipid cleaning properties of an aqueous composition for contact lenses and prevent the overgrowth of harmful bacteria, yeast and molds without adversely affecting the comfort or safety in terms of the level of toxicity to eye tissue.

Abstract: A portable filtration system for a deep fat fryer capable of operation in a stationary mode in which the filtration process is conducted internally within the fryer. The filtration system may alternatively be operated in a portable mode in which an external wand is used to return the filtered oil to the fryer or other vessel such as a disposal vessel.
