Quat-free surface treatment powders comprising a peroxide source, an acyl group donor and an alkalinity source are used to disinfect and/or sanitize hard surfaces. The surface treatment powders can be applied to a hard surface and left there for a period of time. The surface treatment powders are ambient moisture activated, which means that they can generate peracetic acid when a portion or all of the powder that is on the hard surface adsorbs water from the atmosphere. In addition or alternatively, the surface treatment powders are activated, i.e., generate peracetic acid through the incidental or purposeful addition of liquid thereto.

Provided herein are preservative composition of a preservative agent with a polyglycerol ester having a synergistic effect which allow for a reduction in the amount of the preservative agent necessary to be an effective preservative in an end-use formulation.

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 disinfecting 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.

A two-part formulation for creating a decontamination solution may comprise a first part comprising a peracid (e.g., peracetic acid (PAA), acetic acid, hydrogen peroxide) and a second part comprising a pH adjuster (e.g., a pH modifier, such as ethanolamine or disodium phosphate), in which the first part and the second part are maintained separately from each other. To assist in increasing the stability of the solution after the first part and the second part are mixed with water, including hard water, the first part and the second part should lack any chelants that could reduce the stability of the solution. Stability reducing chelants may include ethylenediaminetetraacetic acid (EDTA), tetrasodium EDTA, methylglycinediacetic acid trisodium salt, diethylenetriaminepentaacetic acid pentasodium salt, sodium citrate, nitrilotriacetic acid trisodium salt, and glutamic acid diacetic acid tetrasodium salt.

A disinfectant system, comprising a first aqueous composition having a peracid reactant compound that is either a peroxide compound or an organic acid compound, and a second aqueous composition comprising the peracid reactant compound not selected for the first composition. Each composition is applied separately to, and combined upon, a surface to form a reaction layer, within which a peracid is formed in situ, disinfecting the surface. The compositions can have a flash point, surface tension, and vapor pressure compatible for application as a spray, mist, aerosol, or fog, and can be formulated with an alcohol blend that enables the reaction layer to completely evaporate from the surface after disinfection is complete. In use, the disinfectant systems disclosed herein have up 99.999% antimicrobial efficacy against organism such as Staphylococcus aureus, Pseudomonasaeruginosa, and Candida auris.
