1. cosmetics-grade/household products 既talc 已經係asbestos-free
2. The International Agency for Research on Cancer (IARC)
is part of the World Health Organization (WHO). Its major goal is to identify causes of cancer.
IARC classifies talc that contains asbestos as “carcinogenic to humans.”
Based on the lack of data from human studies and on limited data in lab animal studies, IARC classifies inhaled talc not containing asbestos as “not classifiable as to carcinogenicity in humans.”
Based on limited evidence from human studies of a link to ovarian cancer, IARC classifies the perineal (genital) use of talc-based body powder as “possibly carcinogenic to humans.”
