It was once said on the Internet that waterproof putty was poisonous. Is waterproof putty poisonous?

Putty powder is a kind of decoration material and the basic material for repairing or leveling the wall. Only by scraping putty first can the next decoration work be started. There are many classification methods of putty powder, among which, according to the function of putty powder, there are flexible putty, anti-crack putty and waterproof putty. The main component of putty powder is semi-hydrated gypsum powder (that is, cooked gypsum powder), in addition to a small amount of paint base, filler and appropriate amount of color pigment. Among them, the main coloring pigments are iron red, carbon black and chrome yellow. The fillers are mainly heavy calcium carbonate and talcum powder. It can be seen that the raw material of putty powder is a natural inorganic mineral, which is not toxic in itself. Waterproof putty only adds waterproof and water-resistant materials to putty powder, such as organic rubber powder and water-retaining agent. Organic rubber powder and water-retaining agent are basically harmless, so waterproof putty is harmless and will not cause harm to human health.
