7 Hidden Chemicals in Baby Products You Should Avoid

When I had my first baby, I thought I was doing everything right. I bought the cutest lotions, the best-smelling nappies, and all those “gentle” baby products lining the supermarket shelves. It wasn’t until a stubborn rash appeared on my daughter’s skin that I started flipping those bottles over and actually reading the ingredients.

What I found shocked me. Words I couldn’t pronounce. Chemicals linked to hormone disruption. Fragrances hiding dozens of undisclosed ingredients. I felt frustrated, overwhelmed, and honestly a bit betrayed. Why wasn’t this information easier to find?

If you’re feeling the same way, you’re not alone — and you’re in the right place. Let’s break down seven hidden chemicals commonly found in baby products that you might want to avoid, without the overwhelm or the guilt trip. Just one mum to another, sharing what I wish I’d known from the start.

1. Fragrance (Parfum)

This one tops the list because it’s everywhere — and it’s sneaky. The word “fragrance” or “parfum” on a label can actually represent dozens (sometimes hundreds) of different chemicals. Companies aren’t required to disclose what’s in their fragrance blends because they’re considered “trade secrets.”

The problem? Many fragrance ingredients are linked to allergies, skin irritation, respiratory issues, and even hormone disruption. That lovely “baby fresh” scent? It might not be so innocent after all.

What to do: Look for products labelled “fragrance-free” (not just “unscented,” which can still contain masking fragrances). Or choose products scented only with pure essential oils — though even these should be used sparingly on little ones.

2. Parabens (Methylparaben, Propylparaben, Butylparaben)

Parabens are preservatives used to extend the shelf life of products like baby lotions, shampoos, and wipes. They’re effective at preventing mould and bacteria growth, but research has raised concerns about their potential to mimic oestrogen in the body.

For tiny, developing bodies, this is something many parents prefer to avoid. While the debate continues in scientific circles, I personally choose to err on the side of caution with my kids.

What to do: Check ingredient lists for anything ending in “-paraben” and opt for paraben-free alternatives. Many natural brands now use safer preservatives like vitamin E or rosemary extract.

3. Sodium Lauryl Sulphate (SLS) and Sodium Laureth Sulphate (SLES)

These foaming agents are what make baby wash get all bubbly. The problem is, they can be harsh on delicate skin, stripping away natural oils and potentially causing irritation or dryness — especially for bubs prone to eczema.

SLES can also be contaminated with 1,4-dioxane, a byproduct of manufacturing that doesn’t have to be listed on labels. It’s a known irritant and possible carcinogen.

What to do: Choose sulphate-free baby washes and shampoos. They might not foam as much, but they’re much gentler on sensitive skin. I’ve linked the ones I use below — they work beautifully without all the nasties.

4. Phthalates

Phthalates are plasticisers often hidden under the “fragrance” umbrella or found in plastic baby products like teethers and bath toys. They help products feel smooth and help fragrances last longer.

Research has linked phthalates to developmental issues, hormone disruption, and reproductive problems. The tricky part? They’re rarely listed on labels directly.

What to do: Avoid products with “fragrance” or “parfum” listed. For plastics, look for phthalate-free labels and choose silicone or natural rubber alternatives for teethers and toys.

5. Formaldehyde-Releasing Preservatives

This one sounds alarming — because it is. Certain preservatives slowly release small amounts of formaldehyde over time to prevent bacterial growth. You might see them listed as DMDM hydantoin, quaternium-15, imidazolidinyl urea, or bronopol.

Formaldehyde is a known carcinogen and can cause skin irritation and allergic reactions. Not exactly what we want in our baby’s bath products.

What to do: Learn to spot these sneaky preservatives on labels. This is the brand I swear by for baby skincare — they’re completely transparent about their ingredients, and they never use formaldehyde releasers.

6. Mineral Oil and Petroleum-Based Ingredients

Mineral oil, petroleum jelly, and paraffin are derived from petroleum and are commonly found in baby oils, nappy creams, and moisturisers. While they create a barrier on the skin, they don’t actually nourish it — they just sit on top.

The concern here is potential contamination with polycyclic aromatic hydrocarbons (PAHs), which have been linked to cancer. Plus, they can clog pores and prevent skin from breathing naturally.

What to do: Choose plant-based alternatives like coconut oil, shea butter, or jojoba oil. These actually absorb into the skin and provide real moisture and nutrients.

7. Talc

Talcum powder was once a nursery staple, but it’s fallen out of favour for good reason. Natural talc can be contaminated with asbestos, a known carcinogen. Even asbestos-free talc has been linked to respiratory issues when inhaled.

Those little lungs are still developing, and inhaling fine powder particles isn’t ideal for anyone — especially babies.

What to do: Skip the talc altogether. If you want something for nappy changes, try arrowroot powder or cornstarch-based alternatives. Or simply use a good barrier cream instead.

How to Make Safer Choices Without the Overwhelm

I know this can feel like a lot. When I first started reading labels, I wanted to throw out everything in my bathroom cupboard and start fresh. But here’s what I’ve learned: progress over perfection, lovely.

You don’t have to switch everything at once. Start with the products that stay on your baby’s skin the longest — like lotions and nappy creams. Then work your way through washes, wipes, and laundry detergents as you run out.

• Keep a list of the chemicals above on your phone for easy reference when shopping
• Look for certifications like Australian Certified Organic or Choose Cruelty Free
• Don’t trust marketing words like “natural” or “gentle” — always flip the bottle and read the actual ingredients
• Support smaller Australian brands that prioritise transparency

Remember, you’re already doing an amazing job by caring enough to learn about this stuff. Every small swap is a win for your family’s health.
