A groundbreaking NIH-funded study published in Environmental Science & Technology by the American Chemical Society, revealed alarming levels of chemical exposure in young children aged 2-4. Researchers tested urine samples from 201 toddlers across four states and detected 96 different chemicals, with many originating from everyday cosmetic and personal care products. Among these 96 chemicals some were cosmetic ingredients:
Cosmetic Ingredients of Concern
Parabens – Widespread Detection
- Found in: Cosmetics, lotions, shampoos, and pharmaceuticals
- Status: Commonly detected across 90% of children
- Trend: Levels decreased from 2010-2021, but remain prevalent
Triclosan – Declining but Present
- Found in: Antibacterial soaps and personal care products
- Status: Previously widespread, now showing declining trends
Benzophenones – UV Filter Chemicals
- Found in: Sunscreens, cosmetics, and plastics
- Exposure Route: Direct skin application and environmental contamination
Phthalates – Plasticizer Exposure
- Found in: Personal care products, cosmetics, and household items
- Detection Rate: Multiple phthalates found in over half of children
- Trend: Most phthalates showing declining levels
Demographic Disparities
Higher Risk Groups:
- Children from racial and ethnic minority groups showed elevated levels of parabens and several phthalates
- Younger children (age 2) had higher chemical levels than 3-4 year olds
- Later-born siblings had higher exposure than firstborn children
