The Women's Environmental Network's Sanpro campaign first raised concerns about chemicals in sanitary pads and tampons in 1989. Their concern about dioxins resulting from the bleaching process led manufacturers to switch to chlorine dioxide or hydrogen peroxide, while the risks of toxic shock syndrome led them to recommend 100% cotton tampons
Natracare manufacture a range of feminine hygiene products, including organic tampons and washable menstrual pads.
A menstrual cup, worn internally during menstruation, is reusable, works well and reduces the waste disposal issue of upwards of 100 tampons and/or towels per year. The Mooncup made of synthetic silicone, might suit women who have an allergy to rubber.
