All Crunchy Chemist products are non-toxic, greywater-safe & biodegradable. Every product is made with only 4 ingredients or less, all of which are food grade and organic. We do not use preservatives of any kind. All of our products are highly concentrated, which not only means you get a lot of "bang for your buck" but this allows them to preserve for years without any refrigeration necessary.
Please note that while all Crunchy Chemist products are non-toxic and made with only food grade ingredients, they are NOT intended for ingestion and the FDA has NOT approved any of them for internal use.
