A composition for use as a hard surface cleaner, sanitizer and/or disinfectant is disclosed. The composition according to one embodiment comprises an arylsulfonic acid, a source of peroxide, an effective amount of a stabilizer and water. A method is provided of cleaning, disinfecting and/or sanitizing a hard surface, the method comprising providing the composition, providing a surface which requires cleaning and applying the composition onto the surface for a duration of time sufficiently long enough to destroy micro-organisms present on the surface.

A sterilization validation system and method are disclosed that ensure sterilization of packaging materials that contain certain sterilized items that have been sterilized in a cleanroom environment. In accordance with the disclosed subject matter, garments (or other items or materials) that are sterilized inside autoclave or breather bags may be secured within tote liners that ensure sterility of the exterior of the breather bags containing the garments. Not only is it possible to ensure a recipient that the garment is sterile, but it is also possible to verify that the outside of the breather bag itself is also sterile, since the breather bag will remain sterilized inside the tote liner during shipping.

The patent disclosure covers antibiofilm compositions, wound dressings, cleaning methods and treatment methods. The antibiofilm composition is comprised of between about 0.05% (w/w) to about 0.20% (w/w) benzalkonium chloride; between about 0.20% (w/w) to about 0.50% (w/w) 3-(tri-methoxysilyl)propyldimethyl octadecyl ammonium chloride; between about 0.25% (w/w) to about 0.75% (w/w) phenoxyethanol and between about 98.55% (w/w) to about 99.5% (w/w) deionized water. Disclosed are wound dressings having a reservoir of the antibiofilm composition. In the field of inanimate surfaces, disclosed are methods to clean and clean and protect inanimate surfaces. In the field of animate surfaces, disclosed are methods for the treatment of nose, ear and skin/facial disorders associated with biofilms.

Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.

A preform is sterilized by a preform sterilizer. The preform is blow-molded by a blow-molding device to manufacture a container. Next, the container is filled with a culture medium by a filling device without sterilizing the container by a container sterilizer, and the container is plugged by a plugging device. Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container. A degree of sterilization in the container sterilizer is adjusted on the basis of a verification result.

A device capable of stably obtaining gas of a sterilizer containing hydrogen peroxide for a long time is provided. A cleaning device that cleans a heating surface that gasifies a sterilizer of a gasifier for a sterilizer is provided, and after an operation for a fixed time period, the heating surface is cleaned.

The present invention is directed to a composition in solution (often, an aqueous solution) which comprises a combination of molecular iodine (I.sub.2) and an acceptable source of iodate (IO.sub.3), and an acid (inorganic or organic), wherein iodide and iodate are present in the composition at a molar ratio of about 0.1 to about 25, the concentration of uncomplexed molecular iodine is a disinfectant, biocidal and/or antimicrobial (depending upon the end use of the composition) effective amount the concentration of acid in the composition is effective to provide a buffering pH in the composition ranging from about 1.5 to about 6.5. Compositions according to the present invention are storage stable for unexpectedly long periods of time (up to about 5 years), and find use as dis infecting solutions, as germicides and/or biocides (e.g. antiviral, antibacterial, antifungal, antispore etc.) for various surfaces and solutions including living and inanimate surfaces and are particularly useful because of their low cost, their reduced use of iodine, their activity (because of the high concentration of free molecular iodine in solution), their reduced environmental impact, their long term storage stability and their reduced toxicity. They also have particular utility in treating food surfaces to retard spoilage, increase useful shelf-life and minimize the human and economic cost of food waste. The compositions inactivate viruses, bacteria (both gram negative and positive), spores and fungi. Compositions according to the present invention may be used and stored in a variety of materials, given the substantial absence of corrosion (non-corrosive) these compositions display. Dental compositions (e.g. preprocedure rinses and other compositions) and methods related thereto are also disclosed.

The present invention relates to a method for sterilizing stretching means (12) of a container moulding device (10) fitted to a plant for manufacturing thermoplastic containers obtained by stretch-blow-moulding from production preforms, the said method for sterilizing the stretching means (12) comprises at least the steps consisting in: —introducing a determined quantity of a sterilizing agent into a sterilization preform (30), —during a step referred to as a conversion step, converting said sterilization preform (30) into a hollow body (50) by stretching—blowing into the said moulding device (10), said introduction of the sterilizing agent being performed in the vapour state in a sterilization preform (30) at a temperature that allows a uniform film of mist to be deposited by condensation onto an internal surface (32) of said sterilization preform (30), and in that at least two sterilization preforms (30) are then converted successively into hollow bodies (50) in the one same moulding device (10).

Aspects of the invention include methods for reducing a pathogen population. Methods according to certain embodiments, a source of the pathogen is contacted with a plurality of microdroplets having one or more reactive oxygen species. In certain embodiments, methods include producing the microdroplets by outputting an aqueous composition from an orifice of a flow channel to produce a plurality of microdroplets having one or more reactive oxygen species. In certain embodiments, methods include producing microdroplets through the condensation of water by contacting solid carbon dioxide with an aqueous composition such as by dropping the aqueous composition on the solid carbon dioxide or submerging the solid carbon dioxide in the aqueous composition to produce a plurality of microdroplets having one or more reactive oxygen species. Compositions of a plurality of microdroplets having one or more reactive oxygen species are also provided. Systems for practicing the subject methods are also described.
