The present application provides water-enhancing, fire-suppressing hydrogels that are formulated to minimize toxicity and negative environmental impact. The present application provides a composition comprising: (i) at least one thickening agent; (ii) at least one liquid medium; and, optionally, (iii) one or more suspending agents, wherein the composition consists of &#x3e;75%, by weight, consumer-grade components and wherein the composition is a concentrate that can be mixed with water or an aqueous solution to form a fire-suppressing, water-enhancing hydrogel. Each of the at least one thickening agent, suspending agent and liquid medium can be non-toxic and biodegradable. Also provided are the fire-suppressing, water-enhancing hydrogel and methods of production and use thereof during fire fighting or fire prevention.

Water-enhancing, fire-suppressing hydrogels

The present application provides switchable, homogeneous paint composition and methods of painting and/or forming films or coatings using the composition. The composition includes a liquid having an aqueous solution and dissolved acid gas (e.g., carbonated water), and a switchable polymer. The switchable polymer converts from a protonated, water-soluble form in the liquid to a water-insoluble unprotonated form following removal or substantial removal of the liquid and acid gas.
