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.

Precursor polyelectrolyte complexes compositions

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. The system may allow interchangeable use of a quaternary amine disinfecting composition.

Precursor polyelectrolyte complex compositions in dual chamber dispensing system

The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency. Also provided are means to form stable associative polyelectrolyte complexes in aqueous solutions having R values from about 0.10 to 20, including near stoichiometric R values approaching 1, being the ratio of charged groups present on the component polyelectrolytes employed.

Polyelectrolyte complexes

A temperature sensor assembly is described that includes a sensor probe including a probe head and a probe shaft. At least a tip of the sensor probe includes a material with a thermal conductivity proportionality constant greater than stainless steel. A temperature sensor is positioned within the probe shaft adjacent to the tip. A nose piece is positioned on the probe shaft opposite the probe head. The nose piece includes a material with a thermal conductivity proportionality constant greater than stainless steel. The temperature sensor assembly also includes a collar positioned around the probe shaft between the probe head and the nose piece, the collar is capable of rotating relative to the probe shaft during installation of the sensor assembly.

Temperature sensor assembly

The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide a cleaning benefit and surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions and at least one oxidant selected from the group: alkaline metal salts and/or alkaline earth metal salts of hypochlorous acid, hypochlorous acid, solubilized chlorine, any source of free chlorine, acidic sodium chlorite, active chlorine generating compound and any combinations or mixtures thereof. Also provided are means to form stable associative polyelectrolyte complexes with at least one oxidant in aqueous solutions having R values from about 0.10 to 20.

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 M(OCl)(O)(OH)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 &#x2265;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.
