To start, I want to inform everyone I can, and email is the fastest way that I know how. The tampon industry is convinced that we, as women, need bleached white products in order to view the product as pure and clean. The problem here is that the dioxin produced in this bleaching process can lead to very harmful problems for a woman. It has also been linked to endometriosis and lower sperm counts for men. For both sexes, it breaks down the immune system.
Rayon contributes to the danger of tampons and dioxin because it is a highly absorbent substance.
It also stays in a lot longer than it would with just cotton tampons. Using feminine hygiene products that aren't bleached and that are all cotton. Unfortunately, there are very few companies that make these safe tampons. They are usually only found in health food stores. In 1989, activists in England mounted a campaign against chlorine bleaching.
