  • Patent number: 11214759
    Abstract: A polymerizable composition, polymer capsules and a fabric softener composition are provided. The fabric softener composition includes polymer capsules in which cationic groups are introduced on the surfaces thereof, so that early release of a fragrance can be suppressed and aromas can be generated depending on rupture of a shell material of the polymer capsules by light friction at certain times. In addition, the polymer capsules have high adhesion to fibers and are not attached to fibers during washing to minimize the discharged fragrance, so that sufficient aromas can be provided even if a small amount of fragrance is used.

  • Patent number: 10130733
    Abstract: The invention is directed to a method of cleaning and disinfecting a contact lens. The method includes instructing a consumer to disinfect their contact lens comprising the following steps: remove a contact from an eye and position the lens in a lens assembly that includes a cap member; add a disinfection solution to the lens case such that the lens is submerged in the solution upon closure of the lens case with the cap member. The disinfection solution will comprise 0.5 wt. % to 6 wt. % hydrogen peroxide or a chemical precursor of hydrogen peroxide, and a P-metal modulating compound. The presence of the P-metal modulating compound in the disinfection solution decreases the neutralization rate of the hydrogen peroxide. The disinfection system exhibits a pseudo first-order, half-life of hydrogen peroxide from 12 minutes to 30 minutes over an initial sixty minutes of neutralization following exposure of the disinfection solution to a catalyst comprising a P-metal.

  • Patent number: 7550418
    Abstract: An buffered aqueous contact lens disinfecting solution having much lower concentration of disinfecting agents, and less irritating to the eye. The solutions have a tonicity of 200 to 450 mOsm/kg, a pH of between 6 and 8, and a concentration of chloride ions below 1500 ppm. Despite having less than 1 ppm of antimicrobial, the solutions are effective against C. albicans within 15 minutes of contact.
