Most pads and pantiliners use absorbent fibers that have been bleached with chlorine creating dangerous toxins like dioxin. Studies have shown a direct link between dioxin exposure and cancer birth defects and reproductive disorders. The absorbent fibers in Seventh Generation pads and pantiliners are totally chlorine free. We also use a natural absorbent material derived from wheat. Not whitened with chlorine Safer for sensitive skin- no dyes or fragrances Soft cloth-like cover for comfort Reliable protection for moderate flow days Secure no-slip adhesive
