OEKO-TEX Standard 100: What Touches Your Skin

OEKO-TEX Standard 100 is the most widely held textile certification in the world. It appears on everything from baby clothes to hotel bedding. But it certifies something very specific — and it is worth understanding what that is.

 

What OEKO-TEX Standard 100 tests

It tests the finished product for harmful substances. That is it. The certification confirms that the fabric, as manufactured, does not contain chemicals above defined thresholds that could pose a risk to human health.

The test covers pesticide residues, heavy metals, formaldehyde, certain azo dyes, pH levels, and colourfastness. The limits are strict — stricter than many national regulations — and they are updated regularly as new scientific evidence emerges.

Products are tested by independent laboratories. The certification is renewed annually.

What OEKO-TEX Standard 100 does not test

It does not certify how the fabric was produced. Not the farming, not the dyeing process, not the wastewater, not the working conditions. A fabric can be OEKO-TEX certified and still come from a factory with no wastewater treatment and no social auditing.

OEKO-TEX Standard 100 is a product test, not a process audit. It answers one question: is this fabric safe to wear? It does not answer: was this fabric made responsibly?

Why it still matters

Because the question it answers is not trivial. Residual chemicals in clothing can cause skin irritation, allergic reactions, and long-term health effects. Knowing that the fabric against your skin has been independently tested for harmful substances is a basic assurance that most consumers do not think to ask for — but should.

How AVE uses OEKO-TEX

Our Stanley/Stella blanks hold OEKO-TEX Standard 100 certification (Certificate No. 1112055, Centexbel). Combined with GOTS certification for the supply chain and OCS for organic content traceability, OEKO-TEX adds the final layer: the finished fabric is tested and confirmed safe. Three certifications, three different questions answered.
