Tube / Tire Talc?

[weathers]

I've heard people say they used baby powder between the tire and tubes. I've read that the fragerance used in common baby powder is an oil that will degrade the rubber. Is there such thing as an unscented talc that can be purchased locally or do you have to order "tire talc" from spruce. I've also read that someone used glass bubbles instead of talcum powder. I'm just being lazy and would like to pick up something locally rather than putting another order into spruce. Any opinions or experiences would be great.
