PFAS, Formaldehyde and Baby Clothing: Should Parents Be Concerned?

As parents, we all want to know the same thing: Is what touches my baby's skin safe?

With growing awareness of "forever chemicals", formaldehyde and other substances found in some everyday products, it's understandable that many parents are asking more questions about the clothes they buy for their children.

So, should you be worried about PFAS or formaldehyde in baby clothing?

Here's what you need to know—and what to look for when choosing clothes for your little one.

What Are PFAS?

PFAS (per- and polyfluoroalkyl substances) are a large group of man-made chemicals often called "forever chemicals" because they break down extremely slowly in the environment.

They're commonly used to make products resistant to water, stains or grease and have historically been found in items such as outdoor clothing, waterproof textiles, carpets and food packaging.

PFAS aren't intentionally used in most everyday baby sleepsuits, but they may be present in some treated textiles designed to repel liquids or stains.

Scientists are continuing to study the long-term health effects of PFAS exposure, particularly because these chemicals can build up in the environment and in our bodies over time.

What About Formaldehyde?

Formaldehyde is a chemical that has historically been used during textile manufacturing to help fabrics resist creasing, shrinking or mildew during transport and storage.

The amount present in finished clothing is typically very low and is regulated in many countries. However, some people—particularly babies with sensitive skin or eczema—may be more prone to irritation from certain textile finishes.

This is one reason many parents choose to wash new baby clothes before they're worn for the first time.

How Can Parents Choose Safer Baby Clothes?

Rather than worrying about every chemical you've read about online, it's more helpful to focus on buying from brands that prioritise transparency and recognised safety standards.

When shopping for baby clothing, consider:

  • Fabrics that have been independently tested for harmful substances.

  • Brands that clearly explain what their clothing is made from.

  • Quality manufacturing standards.

  • Durable clothing that's designed to last, reducing waste and the need for constant replacement.

What Does OEKO-TEX® STANDARD 100 Mean?

One certification many parents look for is OEKO-TEX® STANDARD 100.

This internationally recognised certification tests textiles and their components for a wide range of harmful substances. Every certified product must meet strict safety limits before it can carry the OEKO-TEX® label.

While no certification can guarantee that a product is completely free of every chemical, OEKO-TEX STANDARD 100 provides reassurance that fabrics have been tested against strict safety criteria designed with human health in mind.

For babies and young children, the requirements are particularly stringent.

Should You Be Worried?

It's completely natural to want the very best for your baby.

The good news is that many reputable baby clothing brands already meet strict safety requirements and use independently tested fabrics.

Looking for recognised standards such as OEKO-TEX® STANDARD 100, washing new clothes before first wear and investing in durable, high-quality pieces are all sensible steps parents can take.
