How we test our products (and what it proves)

June 5, 2026 by Blossom Wings

It's easy to put a reassuring word on a box. It's harder — and more honest — to test the product and show what came back. Here's what testing actually covers, and what it tells you.

What a real test checks

Independent testing of a pad against international hygiene standards looks at concrete, measurable things — not vibes. The meaningful ones include:

• Absorbency — how much fluid the pad holds, and how fast it absorbs.
• Formaldehyde — a chemical you do not want near your skin.
• Optical brighteners (fluorescent whitening agents) — additives used to make products look whiter than they are.
• pH — whether the surface sits in a skin-friendly range.
• Hygiene — that the product is clean and free of harmful bacteria.

Each of those is a number with a pass/fail line. That's what makes a test more useful than a slogan.

What ours has been measured against

Our pads have been independently lab-tested against international hygiene safety standards (GB 15979-2002 and GB/T 8939-2018 — the kind of standards applied to leading global brands). Across the measures above, the results came back clean:

• High absorbency, well beyond the minimum the standard requires.
• No formaldehyde detected.
• No optical brighteners detected — the colour you see is the natural colour of the cotton, not a chemical trick.
• A skin-friendly pH.
• Passed hygiene checks for bacteria and contaminants.

Why we say it this way

We deliberately describe what was tested and what passed, rather than reducing it to a single badge. Numbers you can understand build more trust than a logo you can't verify. As more of our range is tested, we'll report that here too.
