I was advised to use corn starch, asked that worked fine.
The baby powder contains mineral oil. Mineral oil is a petroleum based product. Why would anybody use a petroleum by-product on their skin which absorbs? I use mineral oil to clean guitar strings and that’s about it.
The use of mineral oil got its start back in the patent medicine days of our country. Along with petroleum jelly I wouldn’t recommend it for use on human skin and definitely not internally.
Corn starch makes a mess in sweat.
