From the MSDS sheet: > 6.2 Environmental precautions > Seal leaks when possible without risk. Impound spoiled product as much as possible with inert materials. Do not allow substance to flow into water ways, sewerage systems, basements or confined areas. I'm sure that's referring to the liquid substance; however there's no information on the site as to how the fluoropolymers biodegrade as the sprays wear with foot traffic and end up in the environment. Hopefully someone with chemistry background has more details about this process. https://rain.works/wp-content/uploads/2016/03/Rainworks-Invisible-Spray-MSDS.pdf https://rain.works/wp-content/uploads/2016/03/Rainworks-Invi...

For what it's worth, they address this (superficially) in their FAQ: > Are rainworks bad for the environment? > Heavens no! Once dry, rainworks are completely non-toxic, environmentally safe, and biodegradable. The solvent in Invisible Spray means you should not pour it down the drain, but when used as instructed, its solvent evaporates and does not enter the water system.

I'm skeptical, too. On their site [1] they claim it's "Eco-Friendly & Biodegradable" and that "Once a rainwork is dry, it is non-toxic to the environment!" A different page [2] says: "The spray is a solvent-based formula. Because of the solvent, it is not safe to drink the liquid or inhale the vapor. ... Once the Invisible Spray is sprayed on the ground, the solvent evaporates, leaving only the biodegradable water-repelling ingredients locked to the surface, making it superhydrophobic, creating the rainwork!" Not a chemist, but I don't think fluoropolymers are generally biodegradable. In fact, isn't non-biodegradability (and non-bioavailability) part of the point?
