Well, tampon and pad manufacturers aren't actually required to tell you what exact ingredients make up the entirety of their product.
Seventh Generation's pads and tampons are made from organic cotton, are chlorine free and fragrance free.
Their ingredient list is as follows:
Components: Certified organic cotton (absorbent material, cover and string), water repellent wax (string), cotton (sewing thread).
*Processed 100% totally chlorine free (hydrogen peroxide).
Product Manufactured in: Germany
Ingredient Origins: Globally Sourced
If you want a tampon or pad that won't screw with your body and works just as well as some other brands without giving your vagina a scent, try Seventh Generation.
