Two chemicals widely used in baby lotions, fragrances, and personal care products may be connected to nearly 2 million premature births and approximately 74,000 newborn deaths globally in 2018 alone. A new study published in eClinicalMedicine examined the link between phthalates and adverse pregnancy outcomes, raising important questions about what's really in the products we use on our babies' delicate skin.

What Are Phthalates and Where Are They Found?

Phthalates are chemicals added to plastics to make them softer and more flexible, but they show up in far more places than just plastic toys. Di(2-ethylhexyl)phthalate (DEHP) and diisononyl phthalate (DINP), the two chemicals examined in the study, are commonly found in food packaging, vinyl flooring, medical equipment, and personal care products including shampoos, lotions, and fragrances. For parents trying to create a clean environment for their babies, understanding where these chemicals hide is the first step toward reducing exposure.

The concern isn't just theoretical. Researchers worry that phthalates can interfere with hormones that regulate growth and development. Even small hormonal disruptions during pregnancy might have lasting effects on a developing baby, which is why the connection between phthalate exposure and premature birth deserves serious attention.

What Did the Research Actually Show?

The study investigated the connection between DEHP, DINP, and premature births across 200 countries and territories. Researchers found that Africa, the Middle East, and South Asia had particularly high rates of premature births, alongside rapidly expanding plastics industries and high levels of global plastic waste. While the study did not prove that DEHP and DINP directly or alone cause preterm birth, it adds to growing evidence that phthalate exposure can lead to negative pregnancy outcomes.

To put the scale in perspective, premature birth occurs when a baby is born before 37 weeks of pregnancy. Infants born too early face serious health risks including breathing and feeding issues, developmental delays, cerebral palsy, and sensory problems. In the United States, about one in 10 babies were born prematurely in 2024, making this a significant public health concern.

How to Reduce Phthalate Exposure During Pregnancy and Infancy

• Read Personal Care Labels Carefully: Look for products labeled "phthalate-free" or "fragrance-free" when shopping for baby lotions, shampoos, and skincare items. Many conventional baby products contain synthetic fragrances that may harbor hidden phthalates, so choosing fragrance-free alternatives reduces exposure.
• Minimize Plastic Contact with Food and Skin: Avoid storing baby products in soft plastic containers or using plastic applicators when possible. Choose glass or stainless steel alternatives for storing lotions and oils, and be mindful of vinyl flooring or plastic mats in nurseries.
• Choose Products with Transparent Ingredient Lists: Select brands that disclose all fragrance components rather than listing "fragrance" as a single ingredient. This transparency makes it easier to identify whether phthalates or other endocrine-disrupting chemicals are present.
• Advocate for Cleaner Regulations: Support efforts to strengthen regulations on phthalates in consumer products. Many countries have banned or restricted certain phthalates, but enforcement and labeling standards vary widely.

The study's findings underscore an important reality for health-conscious parents: the products we assume are safe for babies may contain chemicals that warrant closer scrutiny. While the research did not examine all types of phthalates, it reinforces the value of choosing personal care products with clean, transparent ingredient lists and minimal synthetic fragrance.

For expectant parents and those caring for infants, this research serves as a reminder to ask questions about what's in the products touching your baby's skin. The connection between phthalate exposure and premature birth is still being studied, but the evidence is compelling enough that reducing unnecessary exposure makes sense as part of a broader clean living approach to pregnancy and early childhood.
