  • Patent number: 10858617
    Abstract: The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

  • Publication number: 20200230277
    Abstract: This invention relates to systems, methods, and disinfecting compositions for spraying onto surfaces to be sanitized or disinfected. Methods may include providing an aqueous hypohalite disinfecting composition, and providing a spraying system that may include a hand-held spray nozzle through which the composition is sprayed during use, and a pump and associated tubing for conveying the composition to the hand-held spray nozzle. The tubing may be specifically selected to exhibit at least a 65% recovery (no more than 35% loss) of hypohalite after 24 hours of contact between the composition and the tubing. The method may further include conveying the composition from the reservoir to the spray nozzle, and spraying the composition through the nozzle, e.g., onto the target surface. A related system may include similar components. A dilute hypohalite disinfecting composition may be provided for use with the system and/or method.

  • Patent number: 10450536
    Abstract: The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is ?3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.

  • Publication number: 20180355289
    Abstract: This invention relates to extend the benefits of using hypochlorite compounds such as sodium hypochlorite to clean and disinfect articles while reducing or eliminating the side effects of treating an article with a strong oxidant material. The invention relates to a single step process involving mixing of precursor compositions of a suitable hypohalite or hypohalous acid with a solution of a reducing agent. Optionally a buffer may be present in either or both precursor compositions, such that at time of use such active hypohalous acid concentration in the resulting aqueous mixture remains at a sufficient activity level to effect one or more desired benefits against a target substrate for a desired period of time. The oxidant is substantially consumed by reaction with the reducing agent after the time needed for achieving the desired benefit has passed.
