What is the white powder inside of bike inner tubes?

is it toxic? are the tubes safe to use ater the powder has been washed off?What is the white powder inside of bike inner tubes?
No it's not toxic and yes the tube is safe to use after it's been washed off. It's just talcum powder or something similar to make it easier to mount the tire and tube. It also helps keep the tube from getting stuck or caught on anything while it's being stored (in your bike bag or elsewhere).What is the white powder inside of bike inner tubes?
It's pixie dust.





The reason that bike tubes explode is because the faeries that are trapped inside finally manage to break through. All this effort causes them to drop their supply of pixie dust. The dust on the outside of the tubes is also pixie dust from when the mean innertube maker forces them inside, again, making them drop some dust.
More likely then not it is corn starch, it used to keep the tube from sticking together and will allow it to move inside the tire during inflation.. Washing it off will defeat this purpose. Talcum power has been known to cause respiratory problems.
Rubber softener to keep the rubber from becoming dry.


They used disulfiram for a short time till peple got sick after drinking alcohol. Now they call it Antabuse.
keeps the tube from getting pinched and cut. Makes it a little more slipery

Talc Safety


--


Several studies have established preliminary links between talc and pulmonary issues,[4] lung cancer,[5][6] skin cancer and ovarian cancer.[7] This is a major concern considering talc's widespread commercial and household use. In 1993, a US National Toxicology Program report found that cosmetic grade talc caused tumours in animals (animal testing), even though it contained no asbestos-like fibres.[5] Scientists have been aware of the toxicity of talc since the late 1960s, and in 1971 researchers found particles of talc embedded in 75 percent of the ovarian tumors studied.[8] However, the U.S. Food and Drug Administration (FDA) considers non-asbestiform talc, that is, talc which does not contain potentially carcinogenic asbestiform amphibole fibers, to be generally recognized as safe (GRAS) for use in cosmetics.
