• Organic cotton is grown without synthetic pesticides, fertilizers, or GMOs, and it's processed without harsh chemical finishes

• In period products, organic cotton becomes the topsheet of pads and liners and the core of tampons, the parts in direct contact with skin

• Organic cotton matters for period products because intimate skin is sensitive 

• Cora uses organic cotton across its tampons, pads, and liners

Organic cotton is grown without synthetic pesticides, herbicides, fertilizers, or GMOs, using practices like crop rotation and cover cropping that support soil health. In finished textiles, processing is done without harsh chemical bleaching or finishing, which is why "organic cotton" usually appears alongside terms like elemental chlorine-free and fragrance-free. 

Certification systems like OCS verify cotton, so the label claim is backed by an audit, not just marketing.

For clean-ingredient period products, the cotton is the part directly touching your skin, the pad or liner topsheet, the tampon core, and the cord. Cora builds the full period lineup with 100% organic cotton in those layers, with elemental chlorine-free wood pulp in pad absorbent cores. Our tampons have an organic cotton core, security veil (fabric surrounding the outside of the tampon), removal cord, and sewing thread, whereas other brands sometimes use synthetic ingredients like polyester for some of these components. 

Plus, there's no fragrance, no dye, and we’re a Certified B Corp.

The skin of the vulva and the lining of the vagina are more permeable and more reactive than the skin on, say, your shoulder. Anything that sits there for hours can cause irritation, dryness, or sensitivity in people who are prone to it. 

Organic cotton skips the synthetic pesticide residues, dyes, and added fragrances that can trigger reactions. For people with reactive skin, eczema, or fragrance sensitivities, the switch can mean fewer flare-ups. Even for people without sensitivities, ingredient transparency and a shorter materials list are reasons enough to choose it.
