Natracare tampons were developed as a direct response to health and environmental concerns about dioxin pollution caused by chlorine bleaching, the extensive use of pesticide spraying on conventionally grown cotton, and the use of rayon and other synthetics in tampons. Natracare tampons are made from only certified organic 100% cotton and are the only fully certified organic cotton tampons available in the world today. They are non-chlorine bleached and women can be reassured that they do not contain synthetic materials, such as rayon, or chemical additives such as binders or surfactants. Certified organic cotton removes the risk of direct exposure to residues from chemical pesticides and fertilisers used on traditional cotton.
