Natracare
The original organic, plastic-free period — now employee-owned.
Period Care
Period care sits against the body's most absorbent tissue, so what it's made of genuinely matters — organic cotton or conventional rayon, chlorine-free or not, fragrance-free or not, and, for period underwear, PFAS-free or not. It's also one of the most-acquired corners of "clean," where the female-founded story often outlives the founder's ownership: Thinx? Kimberly-Clark. Knix? Essity. The Honey Pot? Compass Diversified. Here are the organic tampons and pads, PFAS-free underwear, and menstrual cups that are still owned by the people who make them.

Buyer Beware
Marketed as clean and indie, but owned by conglomerates or holding companies. What to use instead: any of our vetted picks above — each is independently owned, scored for materials safety, and has a full review plus a buy link.
Note: Being conglomerate-owned doesn't make a period product unsafe. The point is ownership and materials — a brand marketed as a clean, female-founded choice may quietly send your money to a paper-goods giant, and acquired products can quietly change.
The single biggest materials decision is the fiber. Conventional tampons are often rayon (or a cotton/rayon blend), a processed fiber; 100% organic cotton is grown without synthetic pesticides and is what the cleanest brands use. Cotton is also less associated with the fiber-shedding concerns of rayon. Look for GOTS-certified organic cotton, not just "natural."
Dioxins can form as a trace byproduct when fibers are bleached with chlorine. US brands have largely moved off elemental chlorine, but "totally chlorine-free" (TCF) bleaching removes the question entirely — the mark to look for on organic cotton products.
"Fragrance" or "parfum" on a tampon, pad, or wash means undisclosed chemicals against sensitive, absorbent tissue — a common cause of irritation and a place phthalates can hide. For intimate care we favor genuinely fragrance-free products, full stop.
Period underwear relies on stain- and moisture-resistance, which is exactly where PFAS "forever chemicals" get used. Independent testing has found them in some products, and Thinx settled a PFAS class action in 2023. Choose brands that explicitly test for and disclose PFAS-free, ideally with OEKO-TEX-certified fabric.
For textiles, GOTS (organic) and OEKO-TEX Standard 100 (tested for harmful substances) carry real weight; for cups, medical-grade silicone and FDA registration. As always, third-party certification beats an adjective like "clean" or "natural" on the box.
"Clean period" is a story consumers pay a premium for, which is exactly why the big hygiene companies buy the brands that own it. After an acquisition the pressure to cut cost and chase margin grows, and materials can quietly change while the female-founded packaging stays the same. Founder-owned brands answer to their customers, so they're more likely to keep the product honest.
Three things: 100% organic cotton (not rayon or a cotton/rayon blend), "totally chlorine-free" bleaching (so there is no dioxin byproduct), and fragrance-free. That is the whole checklist. Certifications that back it up are GOTS (organic textiles) and OEKO-TEX. Skip anything scented, and be wary of "purified rayon" or undisclosed "fibers" — organic cotton brands tell you exactly what the product is made of.
Modern US tampons are no longer bleached with elemental chlorine gas — that was phased out — but the concern that remains is dioxin, a persistent pollutant that can form as a trace byproduct of chlorine-based bleaching of the rayon or cotton. The FDA says levels in tampons are very low, but because a tampon sits against absorbent mucosal tissue for hours, many people prefer "totally chlorine-free" (TCF) organic cotton, which sidesteps the question entirely.
It has been found in some. Independent testing detected PFAS ("forever chemicals") in certain period underwear, and Thinx settled a class action over undisclosed PFAS in 2023 (without admitting wrongdoing). PFAS are used for stain- and water-resistance, exactly what period underwear is designed to do, so it is a real thing to check. Look for brands that explicitly test for and disclose "PFAS-free," and favor OEKO-TEX-certified fabrics.
A 2024 study led by UC Berkeley and Columbia researchers detected measurable levels of metals — including lead, arsenic, and cadmium — across 30 tampons from 14 brands, in both organic and non-organic products. These are contaminants (from soil, water, or processing), not intentional ingredients, so they will not appear on a label. The research is early and the health significance is still being studied, but it is a genuine open question, and it is one reason we favor brands with transparent sourcing and third-party testing.
For material safety, reusable cups and discs are a strong choice: quality ones are a single piece of medical-grade silicone (or medical TPE) with nothing bleached, scented, or absorbent-polymer-based, and they are reusable for years, which also removes the packaging and additive load of disposables. The main caveats are proper cleaning and following wear-time guidance. We look for medical-grade silicone and, ideally, FDA registration.
Because the "clean period" space has been heavily acquired. Thinx, the period-underwear pioneer, is owned by Kimberly-Clark (the maker of Kotex); Knix belongs to the Swedish hygiene giant Essity; The Honey Pot is owned by the holding company Compass Diversified. Corporate ownership does not automatically make a product unsafe, but it does mean the formula and materials answer to a margin target — and this is a category where the marketing leans hard on "female-founded" and "clean." When a brand is still founder-owned, the person who made that promise is the one keeping it.
