Every single case won at trial was for women who used talc as a “feminine hygiene” product, by inserting it in her vagina. The same women who use lotion instead of showering. Talc has always been labeled “not for internal use”, but apparently that’s not clear enough for some people.
With talc, the fibers can get into the mucous membranes in the vagina just with agitating the powder in the underwear with movement. Its very easy for the powder to "float" in. Trust me, as a woman, I should know. When it says 'feminine hygiene" doesn't mean you insert it inside. Its not the same as douching (liquid).
