How to Read a Pad Label (and What 'Chlorine-Free' Actually Means)
Most pad boxes tell you almost nothing. Here's what the material lines mean, which claims are real (chlorine-free, FSC), which are fluff (dioxin scare), and the three ingredients worth avoiding.

Introduction
A customer once read our box and asked, "where's the dioxin?" She'd seen a viral post claiming pads are full of it. The short answer: modern pads aren't — and the label she was squinting at didn't list dioxin because there isn't any to list. Reading a pad label is mostly about knowing which claims are real and which are scare-flush. Let me walk the box.
What a real material line says
A transparent brand lists the layers. You're looking for:
- Topsheet — "nonwoven polypropylene" or "cotton-feel." Vague "soft top" tells you nothing.
- Core — "fluff pulp + SAP." This is honest and complete; there's no mystery ingredient.
- Backsheet — "breathable film" or "PE film." Breathable costs more and feels better.
- Additives — fragrance, if any, should be named. Its absence should be stated as "fragrance-free," not implied.
The claims that are real
- 1"Chlorine-free" / TCF. Pulp used to be bleached with elemental chlorine, which could leave dioxin traces. Modern mills use elemental-chlorine-free (ECF) or totally-chlorine-free (TCF) processes; TCF is the cleanest claim and is real and certifiable. So "chlorine-free" is a genuine material statement, not marketing fluff.
- 2FSC. Means the wood pulp comes from responsibly managed forests. Real, third-party, and worth something if you care about sourcing.
- 3"Fragrance-free" / "dye-free." Honest and useful — these are the two things most likely to irritate.
The claims that are fear, not fact
The "dioxin in pads" scare comes from old bleaching. Modern TCF/ECF pulp doesn't carry dioxin the way the posts imply, and reputable manufacturers test for it. If a label says chlorine-free and the brand shows a test report, you're fine. Don't pay a premium to a brand that just repeats the scare without showing data.
| Label claim | Real? | What to do |
|---|---|---|
| Chlorine-free / TCF | Yes | Good signal; ask for test report |
| FSC pulp | Yes | Real sourcing cert |
| Fragrance-free | Yes | Worth choosing |
| "Dioxin-free" scare | Misleading | Check bleaching method, not the word |
| "Natural" (no cert) | Vague | Ask what's certified |
Frequently asked questions
Do pads contain dioxin?
Modern pads made with chlorine-free (ECF or TCF) bleached pulp don't carry the dioxin risk that older bleaching processes did. Reputable manufacturers test for it. A "dioxin-free" scare claim is less useful than confirming the pulp is chlorine-free and the brand shows a test report.
What ingredients should I avoid in pads?
Fragrance is the most common irritant and worth avoiding on the part touching skin; added dyes on the topsheet are another. Beyond those, look for a transparent material list (topsheet, core, backsheet) so you're not buying an unnamed "super-absorbent" blend you can't assess.
Is "chlorine-free" the same as "bleach-free"?
Not exactly. "Chlorine-free" (TCF/ECF) means no elemental chlorine was used, which is the meaningful safety claim. "Bleach-free" can imply an unbleached, browner product but isn't a standardized term. TCF is the clean claim to look for, and it's certifiable.
