Does washing organic cotton with biological detergent defeat the object? Read our advice on fabric care for eco baby clothing and toys.

When we choose organic cotton for our babies, it's often with the best intentions to protect their sensitive skin, reduce chemical exposure, and support more sustainable farming practices. But what happens once those clothes, muslins, and toys come home? If we then wash them with conventional biological detergents or treat them with chemical-laden sprays, are we unintentionally undoing the very benefits we chose organic for?

Why it matters Babies’ skin is around 30% thinner than an adult's, which means it's more absorbent and vulnerable to irritation from anything left behind on their clothes or toys. But it’s not just about skin contact. Babies and young children often explore the world through touch and taste chewing on muslins, mouthing teddies, and sucking on the tags of toys. Whatever you wash those items in could end up inside their mouths.

The problem with biological detergents and fabric conditioners Biological detergents contain enzymes and optical brighteners designed to break down stains and improve whiteness. While effective, these chemical residues can remain in fabric and may irritate delicate skin or be ingested if the item ends up in a baby’s mouth. Fabric softeners are often even worse, leaving heavy synthetic coatings on fibres. And many antibacterial sprays used on toys or highchairs contain synthetic fragrances, preservatives, and surfactants that simply aren't designed with a child’s developing system in mind.

A gentler, safer approach If you’ve made the conscious choice to buy organic cotton or natural toys, the best way to protect that choice is to care for those products in a way that’s aligned with your values. Choose natural, non-bio laundry detergents with simple, plant-based formulations. Avoid fabric conditioner completely on anything your child wears, cuddles, or chews. And when it comes to cleaning toys, opt for natural antibacterial sprays made from vinegar or plant-based alcohol products designed to clean safely without introducing new risks.

What to avoid and what to look for Avoid:

• Enzymes (e.g. cellulase, protease, amylase)

• Optical brighteners

• Synthetic fragrances and dyes

• SLS (sodium lauryl sulfate) and harsh surfactants

• Preservatives like methylisothiazolinone

• Fabric softeners

Look for:

• Non-bio detergents with simple, plant-based ingredients

• White vinegar (for softness in the rinse cycle)

• Bicarbonate of soda (to lift odours and soften water)

• Castile soap for delicate items

• Natural antibacterial sprays with recognisable, safe ingredients

Who else needs to hear this message? This post isn’t just relevant to parents, it's a message that also needs to reach brands, suppliers, and manufacturers.

It's not just about raising consumer awareness. It’s also about equipping buyers, product developers, and production teams with the information they need to ask the right questions and make safe, consistent choices throughout the product lifecycle.

If a buyer or sourcing manager is committed to selecting organic fabrics to reduce chemical exposure and support child safety, they also need to consider the care guidance provided to their customers. That guidance is part of the product’s safety journey, not an afterthought.

Equally, if you're a brand working with certified organic materials, your team has a role to play in educating customers not only about the benefits of those materials, but also about how to maintain them in a way that protects children and preserves the product’s value.

And if you work anywhere in the industry with a mission to protect children and our planet, these conversations belong in your toolkit with your team, your suppliers, your friends, and your family. Because the more we share this knowledge, the more empowered we all become to make safer, more sustainable choices for the next generation.

Conclusion The way we care for baby products matters just as much as how they’re made. If you want to be sure you’re supporting your child’s health and protecting your investment in organic, chemical-free goods, it makes sense to follow through with safer care practices at home.

This isn’t about fear, it’s about knowledge and consistency. The more we learn, the more empowered we become to make small changes that add up to a big difference. Let’s keep protecting our children’s future, one gentle wash at a time.
