I bought a new innertube and it had some kind of powder on it. I thought this was strange and I checked an older tube I never used that was still in the box and it did not have any powder on it. I'm concerned that if there is anything abrasive on the tube I don't want it getting in my rims or tires because it could cause wear on the tube or even the next tube I put in.

I've attached a photo of the powder. Can anyone tell me what it is and if it is normal and if it is okay to use this inner tube?
