OEKO-TEX® Standard 100 appears on a lot of bedding labels. Here is what it actually means, what it tests, what it doesn't cover, and whether it should influence your buying decision.
Is OEKO-TEX certification important for bedding?
Yes — for one specific reason: it independently verifies that the fabric has been tested and found free from harmful substances. This matters for bedding because you spend 6–8 hours per night in direct skin contact with your sheets. OEKO-TEX® Standard 100 tests for over 100 harmful substances including pesticide residues, heavy metals, formaldehyde, and pH levels. It is not self-declared — it requires third-party laboratory testing and annual renewal.
What does OEKO-TEX Standard 100 actually test?
- Pesticide residues — including those used in conventional cotton and flax farming
- Heavy metals — lead, cadmium, chromium, and others
- Formaldehyde — used in some fabric finishing processes
- pH value — fabric that is too acidic or alkaline can irritate skin
- Colorfast dyes — dyes that don't bleed or transfer to skin
- Allergenic dyes — dyes known to cause allergic reactions
What doesn't OEKO-TEX Standard 100 cover?
OEKO-TEX® Standard 100 tests the finished fabric — it does not certify the entire supply chain, labor conditions, or environmental impact of production. For supply chain and environmental certification, OEKO-TEX® STeP or GOTS (Global Organic Textile Standard) are more comprehensive. For most consumers buying bedding for skin safety, Standard 100 is the relevant certification.
How do I know if a brand's OEKO-TEX claim is real?
Every legitimate OEKO-TEX® Standard 100 certificate has a unique certificate number that can be verified at oeko-tex.com/certificate-check. If a brand claims OEKO-TEX certification but cannot provide a certificate number, the claim is unverified. SCANDALINEN's OEKO-TEX® Standard 100 certificate is available on request — contact us at scandalinen@gmail.com.
Does linen need OEKO-TEX certification?
Linen (flax) is naturally more resistant to pests than cotton and is traditionally grown with fewer pesticides. However, the dyeing and finishing process — stonewashing, pre-washing, color treatment — introduces chemicals that can remain in the fabric. OEKO-TEX® certification covers the finished fabric including dyes and finishes, not just the raw fiber. For colored linen bedding especially, certification matters.
Frequently Asked Questions
What is OEKO-TEX Standard 100 certification?
OEKO-TEX® Standard 100 is an independent certification that verifies a fabric has been tested and found free from over 100 harmful substances including pesticide residues, heavy metals, formaldehyde, and allergenic dyes. It requires third-party laboratory testing and annual renewal — it is not self-declared.
Is OEKO-TEX the same as organic?
No. OEKO-TEX® Standard 100 tests for harmful substances in the finished fabric — it does not certify that the fiber was grown organically. Organic certification (GOTS) covers the entire supply chain from farming to finished product. A fabric can be OEKO-TEX certified without being organic, and vice versa.
Does SCANDALINEN have OEKO-TEX certification?
Yes. All SCANDALINEN French linen and bamboo linen fabric is OEKO-TEX® Standard 100 certified. The certificate is available on request at scandalinen@gmail.com.
