Why OEKO-TEX® STANDARD 100 Matters for Baby Clothes

Babies spend up to 20 hours daily in direct contact with clothing and bedding fabrics. Babies’ skin is thinner and more absorbent than an adult's, which means they are more likely to absorb chemicals or irritants through contact. Conventional baby clothes can contain unlisted chemical finishes, dyes, and manufacturing residues that may cause skin allergies or hormonal disruption. These effects are particularly concerning during infants' critical development stages.

OEKO-TEX® STANDARD 100 certification ensures that baby clothing has been independently tested and cleared for over 1000 harmful substances, helping remove uncertainty about fabric safety. Choosing OEKO-TEX® STANDARD 100 certified baby clothes is a proactive way to reduce a baby's exposure to harmful substances during their most vulnerable stages of development. Babies' delicate skin is protected and peace of mind is gained when choosing OEKO-TEX® STANDARD 100 certified baby clothes from day one.

What Is OEKO-TEX® STANDARD 100?

OEKO-TEX® STANDARD 100 is one of the most globally recognized certifications for textile safety. It confirms that every component of a textile product—including fabric, thread, labels, snaps, and zippers—has been independently tested for harmful substances. OEKO-TEX® STANDARD 100 updates its testing criteria annually to reflect the latest scientific research and regulatory standards. These requirements exceed national and international safety laws, providing extra protection when choosing baby clothing. Only textile products that pass rigorous lab testing are eligible to carry the OEKO-TEX® STANDARD 100 label. Manufacturers, retailers, and parents worldwide trust this certification for textile safety.

What Does OEKO-TEX® STANDARD 100 Test For?

OEKO-TEX® STANDARD 100 certification tests for over 1000 harmful substances, including both legally regulated and non-regulated chemicals that may harm human health. Testing covers formaldehyde, azo dyes, heavy metals like lead and cadmium, pesticide residues, volatile organic compounds, phthalates, flame retardants, and allergenic dyes. Even if a chemical isn't banned in your country, OEKO-TEX® STANDARD 100 may flag it as unsafe based on updated health research. The certification reflects current findings in toxicology, global legislation, and consumer safety. STANDARD 100 applies the strictest testing limits to products designed for babies under 36 months old.
Understanding OEKO-TEX® STANDARD 100 Product Classes

OEKO-TEX® STANDARD 100 divides certified products into four classes, based on how close they come into contact with the skin and who uses them. Class I products are designed for babies and toddlers up to age three and must meet the strictest limits for harmful substances. Class II covers items worn close to the skin, like underwear and t-shirts. Class III includes products not in direct contact with skin, such as jackets and outerwear. Class IV applies to home textiles like curtains and table linens.

When shopping for baby clothes, look for the OEKO-TEX® STANDARD 100 certification. Baby clothing automatically falls under Class I, which accounts for infants' unique sensitivity and includes the most comprehensive chemical testing in the OEKO-TEX® STANDARD 100 system.
