BPA (CAS No. 80-05-7) is classified as toxic to reproduction (category 1B) and skin sensitiser (category 1) under Regulation (EC) No 1272/2008. It also exhibits endocrine disrupting activity, adversely affecting female reproductive system and mammary gland. Recently, BPA has also been suspected to impair the development of the immune system, which may be due to its resemblance to oestrogen.
