The quick answer
BPA has been banned from baby bottles and sippy cups since 2012, but some replacements (like BPS) may have similar concerns. Phthalates remain in many soft plastics and scented products. The safest approach: minimize plastic food contact, especially with heat. Glass, stainless steel, and silicone are reliable alternatives.

Editor's note. This guide synthesizes FDA food contact regulations, peer-reviewed endocrine disruption research, and independent product testing. We focus on practical risk reduction rather than fear-based messaging.
01
What are BPA and phthalates, really?
BPA and phthalates are both plasticizers, chemicals that make plastics flexible and durable. They've been used for decades but have come under scrutiny for potential health effects.
BPA (Bisphenol A):
- An industrial chemical used since the 1950s to make hard, clear polycarbonate plastics and epoxy resins
- Found in some food containers, water bottles, and can linings
- Banned by the FDA from baby bottles and sippy cups in the US since 2012
- Concern: mimics estrogen, potential endocrine disruption
Phthalates:
- Make PVC plastic soft and flexible
- Found in vinyl toys, teethers, food packaging, and scented products (hidden in "fragrance")
- Several specific phthalates banned by the CPSC from children's products in the US
- Concern: potential hormone disruption, linked to developmental effects
The "regrettable substitution" problem: When BPA was banned in 2012, manufacturers often switched to BPS or BPF, similar chemicals that may have similar effects. "BPA-free" doesn't mean "free of endocrine-disrupting chemicals." This is why material choice (glass, stainless steel) is often better than relying on "BPA-free" plastic.
BPA-free doesn't mean safe: many replacements like BPS may have similar concerns. That's why we recommend glass or stainless steel for food contact.
In short
- BPA banned from baby bottles since 2012
- Some phthalates banned from children's products
- "BPA-free" replacements may have similar issues
- Material choice matters more than labels
02
Where these chemicals hide in baby products
BPA and phthalate exposure in baby products comes from a handful of predictable places, and CDC biomonitoring data detect phthalates in most Americans, so knowing where these chemicals hide helps you prioritize. The 2012 US ban removed BPA from baby bottles and sippy cups, but plenty of other products still carry plasticizers:
Highest exposure risk (food contact + heat):
- Plastic bottles and sippy cups: Especially when warmed. Heat accelerates chemical leaching.
- Plastic food storage containers: Particularly with fatty or acidic foods, or when microwaved.
- Plastic utensils and plates: Direct food contact during eating.
Moderate exposure (regular contact):
- Teethers and pacifiers: Go in mouths frequently. Look for silicone or natural rubber.
- Bath toys: Soft plastic bath toys (often #3 PVC) can leach phthalates in warm water.
- Changing pads with vinyl covers: Regular skin contact.
Lower direct exposure but worth noting:
- Scented products: Phthalates hide in "fragrance" on labels. Includes baby lotions, shampoos, and laundry detergent.
- Vinyl flooring and shower curtains: Off-gas phthalates into air.
- Plastic toys: Unless mouthed regularly, exposure is limited.
The heat factor matters enormously: Chemical leaching increases dramatically with temperature. Never microwave plastic. Avoid putting hot foods or liquids in plastic containers. Don't leave plastic bottles in hot cars.
Heat is the biggest multiplier for BPA and phthalate leaching, so plastic that touches warm food or liquid (bottles, containers, microwaved anything) is the first thing worth swapping.
In short
- Heat dramatically increases leaching
- Never microwave plastic
- Teethers: choose silicone or natural rubber
- Fragrance can hide phthalates
03
Safe alternatives for every category
Safe alternatives to BPA and phthalate plastics exist for every baby product category, and they matter because the FDA's 2012 BPA ban covered baby bottles and sippy cups while phthalates remain in many soft plastics and scented products. Here's what we recommend for each product type:
Bottles and feeding:
- Glass bottles: Most inert option. Brands like Lifefactory add silicone sleeves for grip.
- Stainless steel bottles: Durable, no breakage risk. Good for older babies.
- Medical-grade silicone nipples: Standard across quality brands. Safe for food contact.
- If using plastic: Choose polypropylene (#5) which has lowest leaching potential.
Food storage:
- Glass containers with silicone lids: Best for leftovers and meal prep.
- Stainless steel containers: Great for packed lunches. No leaching concerns.
- Silicone storage bags: Food-grade silicone for replacing plastic bags.
- If using plastic: Never microwave. Hand wash to preserve any coatings.
Teethers and pacifiers:
- Natural rubber: From rubber trees. Brands like Hevea and Natursutten.
- Medical-grade silicone: Stable, doesn't leach, easy to clean.
- Avoid: Soft vinyl/PVC teethers, which may contain phthalates.
Bath toys:
- Solid plastic or natural rubber: No water entry means no mold and fewer chemicals.
- Avoid: Squeeze toys that fill with water (mold risk + soft PVC).
Glass and stainless steel eliminate the guessing game entirely. You don't need to decode plastic numbers or track which chemicals are banned this year.
In short
- Glass bottles: most inert option
- Polypropylene (#5): lowest leaching if using plastic
- Natural rubber or silicone for teethers
- Never microwave any plastic

Frequently asked questions
Common questions about plastic safety, answered by our research team.
QWhat is BPA and why is it used in plastics?
**BPA (Bisphenol A)** is an industrial chemical used since the 1950s to produce polycarbonate plastics and epoxy resins, making hard, shatterproof items like water bottles, baby bottles, and food can linings. It can leach into food, especially when heated, raising concerns for fetal, infant, and child development, including brain, prostate, behavior, blood pressure, diabetes, and heart risks.[3][4]
QWhat are phthalates and their role in products?
**Phthalates** are a group of chemicals added as plasticizers to make plastics flexible and durable, found in toys, bottles, cosmetics, lotions, shampoos, and food packaging. They leach out, especially with heat, and are ubiquitous in humans per CDC data; certain types are restricted in children's toys and food contact but replacements may pose similar risks.[1][2]
QWhere do BPA and phthalates hide in baby products?
BPA appears in **hard polycarbonate baby bottles, sippy cups, formula cans, and plastic containers** (often recycling code #7); phthalates in **flexible plastics like teethers, pacifiers, bottles, toys, and personal care items**. Both leach more when heated or into liquids, entering food or skin.[1][2][3]
QWhat health risks are linked to BPA exposure?
BPA exposure, via leaching from plastics and cans, is concerning for **fetal and child brain/prostate development, behavior changes, higher blood pressure, type 2 diabetes, and cardiovascular disease**. It mimics hormones and appears in breast milk; substitutes like BPS/BPF may have similar effects.[3][4][1]
QWhy are phthalates a concern for children's health?
**Phthalates** disrupt endocrine function, acting like hormones, with widespread exposure detected in most Americans. They're linked to reproductive issues, especially risky for children; bans exist for toys/pacifiers/bottles, but nine remain in food contact, and new replacements lack full safety studies.[1][2][5]
QWhat are safe alternatives to BPA and phthalate-containing plastics?
Safe alternatives to BPA- and phthalate-containing plastics include **glass, stainless steel, or certified BPA-free/phthalate-free plastics** (e.g., polypropylene #5, polyethylene #2/#4). Avoid heating plastics; use silicone for baby items. Look beyond 'BPA-free' labels as bisphenol substitutes exist. Recent FDA bans PFAS in food packaging aid transitions.[1][2][5]
QHow can parents reduce BPA and phthalate exposure in babies?
Parents can reduce babies' BPA and phthalate exposure by **avoiding microwaving/dishwashing plastics, hot liquids in plastic bottles, and code #3/#6/#7 plastics**. Opt for glass/stainless feeding items, fresh foods over canned, and phthalate-free cosmetics/toys. Handwashing plastics reduces leaching; exposure occurs via air/dust too.[2][5][7]
QAre BPA-free products truly safe from chemical risks?
BPA-free products are not always free of chemical risk: the **BPA-free** label often means substitutes like BPS, BPF, or phthalate replacements, which may mimic BPA's hormone effects with less-studied risks. Experts recommend non-plastic options like glass/steel for certainty, as polycarbonate (#7) and PVC (#3) commonly harbor these.[1][3][6]
