I was downvoted incorrectly. I sourced my info from a team working on talc litigation. 686 of 1032 tests produced in litigation revealed the presence of asbestos in talcs used in cosmetics from 1948 to 2017. That's "often". Asbestos is a carcinogen, and it often contaminates talcs. Citation: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6784763/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6784763/
