摘要： In one aspect, provided is an aqueous antiseptic composition comprising glycerin 8.5-16%by weight; caprylyl glycol 0.45-3%by weight; and a first ingredient; wherein the first ingredient is acrylates/C10-30 about 0.01-0.1%by weight or ethoxydiglycol about 1-5% by weight. The glycerin, the caprylyl glycol and the first ingredient taken together form a first component. A sum of the first component is more than 13%by weight of the antiseptic composition. Other exemplary embodiments are also described. In certain embodiments, provided is an antiseptic composition useful for making skin or hand sanitizers that has a long-lasting, great antiseptic efficacy but at the same time having skin-moisturizing, low toxicity and low skin-irritating, hypo-allergenic properties, low inflammability, and low production cost.

摘要： In certain exemplary embodiments, an air purifier comprises a housing defining an enclosure and having an air entrance and an air exit; a particulate filter; a NCCO filter material configured to adsorb and decompose at least one gaseous pollutant; an AOG configured to generate at least one oxidant; an oxidant remover configured to remove at least one oxidant; a fan unit configured to generate airflow from the air entrance to the air exit; wherein the particulate filter, the NCCO filter material, the AOG, the oxidant remover and the fan unit are positioned within the enclosure such that during operation, a flow of air passes from the air entrance to the air exit through the particulate filter and the NCCO filter material along a direction of the flow of air. In certain embodiments, the air purifier may ensure safety to users while efficiency in removing contaminants can be greatly improved.

摘要： A respirator (100) includes a face mask (130), a porous filter (230) comprising a filtration material, an air flow system (120) in fluid communication with the porous filter (230) and the face mask (130), and an oxidant generator (850) configured to produce at least one oxidant. The air flow system (120) includes an enclosed container (121) and a blower (310) housed within the enclosed container (121). The air flow system (120) is configured to generate a flow of air such that ambient air passes through the porous filter (230) to the face mask (130). At least one contaminant in the flow of air is adsorbed by the porous filter (230), and the filtration material catalyzes an oxidation reaction between the oxidant and the contaminant to promote decomposition of the contaminant on the porous filter (230). According to another aspect, provided is an air purification system including at least one respirator (100) and a decontamination device (800).
