What Is OEKO-TEX® and Why Should You Care as a Parent?
Certification is the part of my job that sounds dullest and counts most. I read the test reports, so I can tell you what this label does and doesn't promise, including the parts that are less flattering to us. Turn over almost any good baby textile and you'll find a small OEKO-TEX label between the washing instructions and the size. It's easy to miss. But of all the claims sewn into a garment, it's the one that doesn't come from the brand. OEKO-TEX is an independent testing and certification system for textiles, run since 1992 by a network of research institutes across Europe and Asia. A third party tests the fabric in a laboratory and publishes what it finds.
What does OEKO-TEX Standard 100 test?
The certification you'll see most often is OEKO-TEX Standard 100, and the key word is every: every component of a certified product has been tested for harmful substances, not just the main fabric. The thread. The buttons. The zips, the elastic, the prints, the dyes.
Laboratories screen for hundreds of substances, including some that are still legal but raise health concerns: formaldehyde, certain azo dyes, pesticides and heavy metals among them. The criteria are reviewed and tightened every year as the science moves on.
What are the OEKO-TEX product classes?
Standard 100 divides into four classes, graded by how closely a textile lives against the skin. This is the part most parents are never told.
- Class I: products for babies and toddlers up to 3 years, tested to the strictest limits
- Class II: textiles worn next to the skin, such as underwear and adult bedsheets
- Class III: textiles worn away from the skin, like jackets and outerwear
- Class IV: furnishing materials such as curtains and upholstery
Class I is the most exacting of the four. Its limits are tighter because babies chew, suck and sleep face-down on their textiles, and skin this thin absorbs more of whatever it touches. Certain Class I criteria account for saliva resistance, for exactly this reason: everything, eventually, finds a baby's mouth.
Where certification matters
Why OEKO-TEX matters for baby skin
A newborn's skin barrier is still developing, so residues that would never bother you can give your baby a rash. And the contact isn't brief: a cot sheet, a blanket or a swaddle lies against her skin for most of every day and night. I'm not certain anybody has measured, outside a lab, how much of a residue crosses a newborn's skin. The certification exists so that nobody has to find out.
Singapore adds one more reason. Warm, damp skin absorbs more easily, so what's in the fabric your baby sweats into counts for more here than in cooler places. A rash that doesn't clear is always one for your paediatrician. Tested fabric at least rules out one common cause.
How to check a product is certified
Every genuine OEKO-TEX label has a certificate number and the name of its testing institute. Enter the number on the OEKO-TEX website's label check and you can see the certificate yourself. A brand that says certified and can't produce a number has answered the question already.
Certificates expire after a year and are renewed only with fresh testing. A current number means recent results.
One more distinction: OEKO-TEX isn't the same as organic. Organic labels describe how the raw fibre was farmed. Standard 100 tests what's in the finished piece you take home, dyes and trims included. They answer different questions. For a fabric that lies against your baby's face all night, the test of the finished piece is the one we care about most.
What this means when you shop
For anything that touches your baby, look for both on the tag: OEKO-TEX Standard 100 and Class I. Our bamboo bedding and softlines are certified because we wouldn't lay an untested fabric on our own children's cots. Ours is renewed every year, and if you ask us for the number we'll give it to you.

What does OEKO-TEX Standard 100 mean?
It means every component of the product, from fabric to thread to buttons, has been independently laboratory-tested for harmful substances against strict annual criteria.
Which OEKO-TEX class should baby fabric carry?
Class I is the strictest product class, covering textiles for babies and toddlers up to 3 years. It applies the tightest substance limits, including saliva-resistance criteria.
Is OEKO-TEX the same as organic?
No. Organic describes how the raw fibre was grown, while OEKO-TEX tests the finished textile for harmful substances. A product can be either, or both.
How can I verify an OEKO-TEX label?
Every genuine label has a certificate number you can enter on the OEKO-TEX website's label check to confirm it is current and authentic.
Does OEKO-TEX certification expire?
Yes, certificates are valid for one year and must be renewed with fresh testing, so a valid number reflects recent laboratory results.
