What are phthalates? Phthalates – the "everywhere chemical" – can be hard to pronounce, hard to spell, hard to locate, and even harder to make sense of.
Phthalates are chemicals commonly used to make plastics more flexible and durable, which is why they appear in everything from food packaging to personal care items to crib mattresses. The tradeoff, however, has led to growing questions around exposure and long-term impact.
In this guide, we'll break down what phthalates are, where they're found, how they may affect health, and how to identify phthalate-free alternatives.
- What they are: Chemicals used to make plastics more flexible and durable
- Where they're found: Vinyl products, food packaging, personal care items, and some mattresses
- Why they matter: Linked to potential hormone disruption and developmental concerns
- How exposure happens: Through air, dust, food contact, and skin absorption
- What to look for: Phthalate-free labels and materials that avoid PVC or vinyl
What Are Phthalates?
Phthalates are a group of chemical compounds commonly used as plasticizers in various industrial and consumer products. They are added to plastics to increase their flexibility, durability, and transparency, per the EPA.
Odorless, colorless, and highly versatile, some of the most commonly used phthalates include:
- Dioctyl phthalate (DOP)
- Diethyl phthalate (DEP)
- Diisodecyl phthalate (DIDP)
- Diisononyl phthalate (DINP)
- Di-n-butyl phthalate (DBP)
Some phthalates, including DINP and DBP, have already been restricted by the Consumer Product Safety Commission (CPSC) due to studies showing their toxic and harmful effects. However, these restrictions only apply to baby and children's products at levels greater than 0.1% by weight. Read more about the CPSC restrictions here.
Other phthalates may be just as toxic but, as yet, no action has been taken.
How do you pronounce phthalates? It's pronounced "THAL-ates." The "ph" is silent, which is why the word looks more complicated than it sounds.
What Are Phthalates Found In?
Phthalates show up in far more places than most people realize. Because they're used to make plastics more flexible and to help fragrances last longer, they've become common in both household items and personal care products.
You'll often find phthalates in:
- Household materials: Vinyl flooring, shower curtains, food packaging, and containers
- Personal care products: Shampoo, soap, lotion, fragrances, deodorant, and nail polish
- Baby products: Some crib mattresses, pads, plastic toys, and accessories
- Medical materials: Tubing, medical devices, and other flexible plastic components
And that list only scratches the surface. Because phthalates are used across so many industries, they've become a common part of everyday products — often in places you wouldn't expect.
How Does Phthalate Exposure Happen?
People can be exposed through ingestion, inhalation, and skin contact. In practical terms, that means phthalates can enter your body through:
- Food and drink: when phthalates migrate from plastic packaging or processing equipment
- Air and dust: as phthalates slowly escape from products like flooring, furniture, or synthetic materials
- Skin contact: through personal care products like lotions, cosmetics, and fragrances
Unlike some chemicals, phthalates are not chemically bound to the materials they're added to. Over time, they migrate out of products and into the surrounding environment — settling into household dust, circulating in the air, or transferring through direct contact. Even small, repeated interactions can add up over time.
Why Are Phthalates Harmful?
Phthalates have been studied for their potential impact on human health, particularly their ability to interfere with the body's endocrine system — the network of glands and hormones that regulate growth, development, and reproduction.
Risks of Phthalate Exposure
According to the EPA, some phthalates are classified as endocrine disruptors, meaning they can mimic or interfere with the body's natural hormones. Research has linked certain phthalates to:
- Hormonal disruption: which may affect reproductive health and development
- Developmental concerns: particularly in infants and children during critical growth stages
- Reproductive effects: including impacts on fertility and pregnancy outcomes
- Respiratory issues: with some studies suggesting links to asthma and allergies
A 2025 review by RTI International determined that even with current alternatives and regulation, phthalate exposure remains widespread — making even small, repeated exposures worth understanding.
Who Is Most Vulnerable?
While phthalate exposure can affect anyone, some groups may be more sensitive to its effects:
- Pregnant women: due to potential impacts on fetal development
- Infants and children: whose bodies are still developing
- People with frequent product exposure: such as through personal care or occupational environments
What About Regulations?
In the U.S., certain phthalates have been restricted in children's products by the CPSC, particularly at levels above 0.1% in items like toys and child care articles. However, not all phthalates are regulated equally, and in some cases similar chemical substitutes may be used in place of restricted compounds.
Are Phthalates Harmful to the Environment?
Phthalates can leach into soil, water, dust, and air. While they break down relatively easily, they're released at high enough levels to be concerning — especially due to their endocrine-disrupting properties, which can harm wildlife and ecosystems.
Phthalates have been linked to reproductive and developmental issues in aquatic organisms. The phthalate DBP has been linked to the decline of amphibian species even at low concentrations, and as phthalates accumulate in the environment they can re-enter the human food chain.
Why Are Phthalates Used in Crib Mattresses?
Phthalates are most commonly found in crib mattresses as part of vinyl (PVC) waterproof covers — popular because they're inexpensive, flexible, and effective at blocking moisture.
Waterproofing matters in a crib mattress. Without it, diaper leaks and spills can seep inside and allow mold, bacteria, and odors to develop. But phthalates aren't a safe trade-off — especially given that newborns sleep up to 18 hours a day, making prolonged exposure a real concern for a vulnerable population.
How an Organic Crib Mattress Can Help
Naturepedic uses a food-grade polyethylene waterproof layer made from non-GMO sugarcane instead of vinyl. This creates an effective moisture barrier without the need for phthalates — so parents don't have to choose between a hygienic mattress and a chemically safer one.
Frequently Asked Questions About Phthalates
What Are Parabens and Phthalates?
Parabens and phthalates are two different types of chemicals commonly used in consumer products. Parabens are preservatives that prevent bacteria and mold growth, mostly in cosmetics. Phthalates are plasticizers that make materials more flexible or help fragrances last longer. Both are often discussed together because of concerns about how they may interact with the body's hormonal systems.
How Can I Find Phthalate-Free Products?
Look for "phthalate-free" labels and avoid vinyl (PVC) and flexible plastics where possible. Choosing fragrance-free personal care products also helps, since phthalates are sometimes used to extend scent. Opt for brands that clearly disclose their materials and certifications.
What Is Dioctyl Phthalate (DOP)?
Dioctyl phthalate (DOP) is a phthalate commonly used to make plastics more flexible and durable, historically found in vinyl materials, flooring, and synthetic leather. Like other phthalates, it has faced increased scrutiny and regulation due to its potential health and environmental impacts.
Are Phthalates and Fragrances Related?
Yes — phthalates are sometimes used in fragranced products to help scents last longer. Because fragrance formulas are often considered proprietary, phthalates may not always appear clearly on ingredient labels, which is why fragranced products frequently come up in discussions about phthalate exposure.
Are Phthalates Found in Clothing?
Not typically in most fabrics, but they can appear in synthetic leather (PVC), plastic prints, waterproof coatings, and some accessories or textile finishes. To reduce exposure, choose simple untreated fabrics, look for GOTS-certified options, and avoid vinyl-based materials.
Don't Sleep With Phthalates
Phthalates are a part of modern life. While it's nearly impossible to avoid them entirely, understanding where they show up helps you make more informed decisions — and few places matter more than where you sleep. Your bedroom is where your body rests, resets, and recovers every night. The materials closest to your body can play a meaningful role in your overall health.
