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.
Abstract:
Described is a kit for clearing drain pipes. The kit may include a bottle having a reservoir containing drain-clearing composition and a neck extending from the reservoir. The neck may have a first engagement member. The kit also may include a drain-clearing tool formed of plastic and having a handle at one end, a flexible shaft extending from the handle for placement into a drain pipe, a ribbed surface extending along a length of the shaft for scouring a surface, and a plurality of longitudinally-spaced barbs covering a substantial portion of the length of the shaft. The bottle and drain-clearing tool may be assembled together, using a package, into a kit. The package may define an interior space to house the drain-clearing tool and/or a neck-receiving portion having a second engagement member that may complement the first engagement member of the neck of the bottle. Methods of using such kits are also disclosed.
Abstract:
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.
Abstract:
Pop-up dispensing systems for dispensing substantially dry wipes while minimizing “clumping” and “fallbacks”, or sticking of tacky, adhesive binder loaded wipes within the interior of the container body. The dispensing system includes a container having a container body forming an interior region, and a plurality of stacked substantially dry wipes or other substrates. The wipes may be loaded with an adhesive binder or other material. By selecting and providing particular characteristics relative to the cross-sectional area of the dispensing orifice (e.g., 22 cm2 to 75 cm2) and the separation force profile (e.g., 1 gf/cm2 to 6 gf/cm2), wipes which are loaded with an adhesive, tacky binder material can be dispensed one at a time, while minimizing clumping and fallbacks, and any tendency of the wipes to becoming stuck within the container body.

Abstract:
The invention relates to compositions including a hypohalite or hypochlorous acid and a soluble salt of 2,4,6 mesitylene sulfonate. The compositions may include a surfactant, a buffer, or combinations thereof. Other adjuvants may also be present. Such compositions do not require the inclusion of high concentrations of sodium hydroxide or other soluble hydroxide salts to drastically increase pH (and thus stability), although such hydroxides may be present if desired.
Abstract:
The invention relates to preloaded cleaning and sanitizing wipes comprising a nonwoven substrate, and a cleaning formulation loaded onto or within the nonwoven substrate. The cleaning composition may include about 0.001% to about 10% by weight of an antimicrobial compound comprising a quaternary ammonium compound, less than about 4% by weight of an alcohol solvent containing a single hydroxyl group, a preservative, about 0.05% to about 10% by weight of a glycol solvent (e.g., preferably a glycol ether solvent), about 0.05% to about 10% of one or more surfactants, and water. The composition may have a pH from about 4 to about 8.
Abstract:
Animal litter having up to a sixty percent reduction in bulk density can be produced by combining flat-shaped cellulosic materials and sodium bentonite clay. Not only is the resulting litter lighter, but it also maintains a high clump strength as compared to clay-based animal litters that contain greater than ninety percent by weight sodium bentonite clay.
Abstract:
The invention relates to applicators for applying a solution or other composition (e.g., an antiseptic composition) to skin of a patient. The applicator may include a container body having a proximal end, a distal end, and a frangible member disposed at the distal end of the body. The applicator includes a first position where the container body and frangible member are a unitary piece (e.g., blow molded as a single piece), and a second position when the frangible member is rotated relative to the body to irreversibly break a weak point therebetween, releasing the composition in the hollow body through an opening. A porous applicator head may be positioned adjacent the distal end of the body and frangible member, so that the composition flows out the body, through the opening, and onto the head. The applicator may be formed in a blow-fill-seal process for improved sterility and ease of manufacture.
