6 Common Toxins Found in Baby Nurseries (+ Safer Swaps)

Phthalates are a group of chemicals used to make plastics soft and flexible, often found in vinyl products like crib mattress covers, changing pads, and baby-proofing items. 

These chemicals have been linked to hormonal disruptions, developmental issues, and asthma.

Safer Swap

Opt for changing pads and mattress covers made from organic cotton or GOTS (Global Organic Textile Standard) certified materials. Natural rubber or organic latex mattresses and pads are excellent alternatives free of phthalates and other harmful plastics.

3. Flame Retardants in Upholstery and Mattresses

Flame retardants, such as polybrominated diphenyl ethers (PBDEs), are often added to baby mattresses, upholstered nursery chairs, and other cushioned items to reduce fire risk. 

Unfortunately, these chemicals can escape from the products over time, accumulating in dust and potentially entering your baby’s body through inhalation or ingestion. Flame retardants are associated with cognitive delays, developmental disorders, and hormone disruption.

Safer Swap

Look for nursery furniture and mattresses labeled as free from added flame retardants. Many brands offer products that meet fire safety standards without using these chemicals. Natural fiber options like wool, which is naturally flame-resistant, or organic cotton mattresses are excellent choices.

Parabens are synthetic preservatives used to prevent the growth of bacteria and mold in skincare products, including diaper creams and lotions. 

Parabens can disrupt hormone function by mimicking estrogen, which may lead to developmental and reproductive issues over time. They are easily absorbed through the skin, making them particularly concerning in products for babies as their skin is around 30% thinner than adult skin and their skin microbiome is still developing. 

Safer Swap

NOLEO 3-in-1 Diaper Care is a safer alternative to conventional diaper creams and lotions. It’s made with just five natural and organic ingredients, free from parabens, and provides a gentle yet effective solution for cleaning, moisturizing, and protecting your baby’s delicate skin. 

5. Pesticide Residues in Baby Clothing

Conventional cotton baby clothing often contains pesticide residues from farming practices, along with other toxic chemicals used during fabric processing. 

Chemical residues in non-organic cotton can cause skin irritation, especially in babies with eczema or sensitive skin. Additionally, long-term exposure to pesticide residues may lead to more serious health issues, including immune system disruption.

Safer Swap

Choose natural fibers such as wool and hemp, and when you can, opt for organic cotton clothing that is certified by GOTS, ensuring the fabric is grown and processed without harmful chemicals. A great option is TØY Baby Clothes, which offers soft, organic baby garments free of pesticides, synthetic dyes, and toxic finishes. 

6. Toxic Ingredients in Disposable Diapers

Many disposable diaper brands use toxic chemicals that can irritate your baby’s skin or cause more serious health concerns over time. 

Common ingredients to watch for include chlorine, used in the bleaching process, and sodium polyacrylate, a super-absorbent gel linked to skin rashes. Fragrances, dyes, and lotions added to diapers may also contain harmful substances like phthalates, which can cause hormone disruption.

Safer Swap

Look for diapers with OEKO-TEX® Standard 100 Certified and EWG-Verified certifications. Alternatively, consider using cloth diapers, which are reusable, gentle on the skin, and free from the harmful chemicals found in disposables.

Pro Parent Tip: Download a Toxic Baby Products App

Trying to find safe products for your baby with so many harmful ingredients in baby products can be overwhelming. We asked NOLEO founder, Lucas Nanini what he recommends parents do to simplify the process.

Lucas advises, “When in doubt, use a baby product ingredient checker. The Good Face App and the EWG Healting Living app are great options that allow you to research for products and ingredients so you really understand what you’re putting on and near your baby’s skin.”

Watch Out for Toxins in Secondhand or Vintage Products

While it’s possible to find ingredient and material information for modern baby products, that’s not always the case with secondhand or vintage products. 

Parents who buy old nursery items should be mindful of toxic chemicals that were commonly used in the past but are now largely banned or phased out. Here are a few to watch for.

Lead in Paint

Lead was commonly used in household paints before being banned in the U.S. in 1978. If you’re using secondhand furniture or vintage toys, there’s a chance they may contain lead-based paint. Exposure to lead can cause developmental delays, learning difficulties, and behavioral problems in children.

How to Avoid It

Test secondhand or vintage items with lead testing kits, especially if you notice chipping or peeling paint. If you suspect lead, it’s best to avoid using the item or have it professionally treated.

Asbestos in Insulation

Some older homes and nursery items may still contain asbestos, a material once used for fireproofing and insulation. Asbestos is now known to cause severe respiratory illnesses, including lung cancer and mesothelioma, particularly when its fibers are inhaled.

How to Avoid It

Be cautious when renovating an older home or purchasing vintage furniture with insulation components. Professional asbestos testing and removal services are recommended for homes built before the 1980s.

Mercury in Thermometers

Mercury was once commonly used in thermometers, particularly vintage glass ones. While most modern baby thermometers are mercury-free, older models may still pose a risk. Mercury is a potent neurotoxin, harmful if inhaled or ingested.

How to Avoid It

If you have an old mercury thermometer, dispose of it properly according to your local hazardous waste disposal guidelines. Opt for a digital thermometer for safer, more accurate readings.

Toxic Baby Product FAQs

What products are not good for babies?

Several baby products may contain harmful chemicals that can negatively impact your child’s health. Products to avoid include:

• Baby lotions and diaper creams containing parabens, phthalates, or fragrances, which can irritate sensitive skin or disrupt hormones.

• Furniture and mattresses made with formaldehyde, flame retardants, or VOCs (volatile organic compounds) found in adhesives and finishes.

• Plastic toys made with PVC or phthalates, which can leach harmful chemicals over time.

• Disposable diapers with chlorine bleaching, fragrances, or dyes, which can cause skin irritation and expose babies to harmful toxins.

• Clothing made from non-organic cotton treated with pesticides and chemical dyes.

Opting for products made with natural, non-toxic materials such as organic cotton, solid wood, and eco-friendly skin care products will help keep your baby safe.

What baby products contain PFAS?

PFAS (per- and polyfluoroalkyl substances), also known as “forever chemicals,” are sometimes found in baby products that are designed to be water-resistant or stain-proof. Products that may contain PFAS include:

• Waterproof crib mattress covers and changing pads, particularly those made with synthetic or treated materials.

• Stain-resistant baby clothing or outerwear with water-repellent coatings.

• Baby food packaging that uses grease-resistant linings, which can transfer PFAS to the food.

• High chairs and strollers with water-resistant fabrics.

To reduce exposure to PFAS, look for products labeled as PFAS-free or made from natural, untreated materials like organic cotton or wool.

What baby lotions contain formaldehyde? 

Some baby lotions and personal care products contain formaldehyde or formaldehyde-releasing preservatives, which act as antimicrobial agents. Formaldehyde can cause skin irritation, respiratory issues, and is considered a carcinogen. Ingredients to watch for include:

• Quaternium-15

• DMDM hydantoin

• Imidazolidinyl urea

• Diazolidinyl urea

• Sodium hydroxymethylglycinate

These chemicals release formaldehyde over time, potentially exposing your baby to this toxic substance. To avoid formaldehyde, choose baby lotions from brands that use natural preservatives or are explicitly labeled as free from formaldehyde and other harmful chemicals.
