Talcum powder as... antiperspirant?

Might be in your Gold Bond Powder - but Whack-a-Moles link and
other articles. say otherwise. Your granddaughter is either importing the talc-based one from somewhere outside North America or more likely is using one of the J&J cornstarch based powders . ( and since it’s your G granddaughter it’s less likely to be a talcum powder as the talc/asbestos/ovarian cancer issue has been a thing since my 33 yr old daughter was a baby. ( I have no idea how much talc is contaminated by asbestos . But I know cornstarch isn’t. )

Talc is also more abrasive than corn starch. Not as bad as asbestos but corn starch works great. If the starch is not consumed in ethanol production it should be very inexpensive too, and grocery store prices strongly indicate it is. Probably costs a lot less than the body powders that are just cornstarch.

Cornstarch does absorb water so readily that easily clumps in the container, I never noticed talc doing that back in the olden days. They may add some ‘anti-clumping’ ingredients but I see a 1 lb. box from Stop&Shop is priced at $0.08 cents an ounce. I think I’m gonna stop paying for CVS brand powder. It’s not a huge budget item but now my wife gets less out of complaining that I waste money when there’s powder all over the bathroom.

BTW, I just looked up various Gold Bond powders - didn’t see talc on the ingredient list for any. Cornstarch, tapioca starch but no talc , although I couldn’t find any information about when the talc was removed.

Johnson and Johnson says otherwise. The bottle of baby powder my granddaughter had came from her local Walmart. There is a warning on the bottle that says the powder contains talc and they say it is safe.

Website says it’s discontinued

and every article I’ve seen ( and the reviews on the product page) says it was discontinued 2 yrs ago. I suppose your granddaughter could have somehow gotten a 2 yr old container recently.

Looking at pictures on the Gold Bond website, I notice that almost all of their product labels say “New” right beside the phrase “Talc Free.”

I suspect that Gold Bond got rid of their talc fairly recently. I can tell you that I bought some of their spray-on body powder within the past year, and it contained talc at that time (I hadn’t looked too carefully at the ingredients, and only realized it after I had used it a few times).
