The present invention provides an oxygen absorbing composition which includes an oxygen reducing agent, water, a carrier, an electrolyte salt, and a humectant salt, which may be the same as the electrolyte salt, present in an amount sufficient to reduce the water activity of the composition to below 0.6. Also included are methods of using the composition.

Abstract: A method of dry coating oxidizable particles with activating particles. The method includes accreting at least portions of the activating particles onto surfaces of the oxidizable particles by mechanically induced juxtapositions to form composite particles; and abrading the composite particles to more evenly distribute the activating component over surfaces of the activating particles.

Abstract: The invention relates to improved resin bonded sorbent compositions and articles of manufacture fabricated therewith, such as housings, structural components and circuit boards. The introduction of sorbents into resinous molding compositions enables the elimination of more conventional bagged sorbent containments. The novel molding compositions of the invention and parts fabricated therewith are multi-functional, beneficially combining structural, mechanical and adsorptive capabilities without requiring the usual reinforcing additives. Consequently, with the omission of reinforcing additives the novel molding compositions of the invention are further characterized by higher adsorptive capacities by allowing for higher sorbent loading factors than prior adsorbent-containing molding compositions.

Abstract: A device for controlling relative humidity in an environment with a solidified humectant composition. The solidified humectant composition is made from a humectant salt, water, and a carrier. The solidified humectant may be formed into a tablet with the aid of a binder, or it may be contained within a thermoformed felt material, a sachet, or a water permeable canister. In a preferred embodiment, the sachet is made of a micro-perforated polyester/paper/polyethylene material. Preferred humectant salts include CaCl2, K2CO3, LiCl, NaCl, K2SO4, and combinations thereof. A preferred embodiment of the present invention includes the use of one or more of: an antimicrobial agent, activated carbon, a volatile organic, a moisture adsorber and an oxygen absorber, in combination with the solidified humectant salt.

Abstract: Heterogeneous oxygen-scavenging particles are formed by dry coating activating component particles onto oxidizable component particles, largely through a succession of mechanical motions. The component particles are repeatedly mixed, compressed, and sheared. Smaller activating component particles coat the surface of larger oxidizing component particles by force-induced contact, while irregularities are removed by abrasion among the particles. The oxygen-scavenging particles can be blended together with a base polymer into a masterbatch having a higher concentration than required for use as an active barrier to oxygen permeation. The masterbatch can be diluted with the same or a compatible polymer to form the active barrier.

Abstract: A hydrocarbon adsorber and a thermoplastic resin combined and formed to a porous scavenger for insertion into the air intake system of a motor vehicle engine. The resulting porous scavenger adsorbs volatile hydrocarbon molecules from raw fuel remaining in the air intake when the engine is shout off. The adsorbed molecules are then stripped or purged from the scavenger and reintroduced into the air intake when the engine is next started.

A method of absorbing acid gases from a confined environment utilizing the above tablet by inserting it into the confined environment.

Abstract: An absorbent mixture consisting of an absorbent such as sodium or potassium polyacrylate, a fluent wax and a channeling agent. A product consisting of a porous member containing a mixture including an absorbent such as sodium or potassium polyacrylate, a fluent wax and a channeling agent.

Abstract: A well dispersed oxygen scavenging particulate compounded in a polymer matrix. The oxygen scavenging formulation consists of iron powder with a mean particle sizes within 1-25 um and pre-coated with at least one or more activating and acidifying powdered compounds, usually in the form of solid organic and inorganic salts of alkaline and alkaline earth metals such as sodium chloride and sodium bisulfate. The pre-coated iron particulate is dispersed into a polymer resin by using a conventional melt processing method such as twin-screw extrusion. The oxygen scavenging compound is mixed with polymer pellets in the solid state prior to melting. The polymer resin pellets and the coated iron powder are preferably treated with a surfactant in the dry state to help dispersing the iron/salt powder with the resin pellets. The melt extruded compounds are pelletized and kept in the dry state to prevent premature activation.

Abstract: A hydrocarbon adsorber and a thermoplastic resin combined and formed to a porous scavenger for insertion into the air intake system of a motor vehicle engine. The resulting porous scavenger adsorbs volatile hydrocarbon molecules from raw fuel remaining in the air intake when the engine is shut off. The adsorbed molecules are then stripped or purged from the scavenger and reintroduced into the air intake when the engine is next started.
