Natracare organic cotton tampons and organic and natural pads 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 feminine hygiene. Women can be reassured that Natracare Ultra pads do not contain synthetic materials, chemical additives such as binders or surfactants, fragrances or dyes and because of the organic and natural materials used, are over 95% biodegradable and compostable. The absorbent core of the pad is made from Forest Stewardship Council certified pulp (FSC) and the cover that is next to your skin is certified organic 100% cotton. The pads are individually wrapped in biodegradable purse packs.
