Can phthalates from personal care products affect kids' antibody response?
Phthalates are used in some fragranced personal care products. New research links pregnancy exposure with changes in children's antibody response, so fragrance-free baby care is a smart swap.
What we know
Phthalates are chemicals used to soften plastics and carry fragrance. They can show up in some skin care, hair care, and scented products. Labels often do not list each fragrance chemical.
A 2024 Environmental Health Perspectives study found that children's use of some skin care products was linked with higher phthalate and phthalate-replacement levels in urine. A 2026 European Journal of Epidemiology study looked at pregnancy exposure and found links between some phthalates and children's serum antibody response.
What this means for your family
This research does not prove that one soap changes a child's immune system. It does show that personal care products can be a real exposure source, and that pregnancy and childhood are important windows for safer choices.
The easiest move is to use fewer scented products on babies and young kids.
Simple safer steps
Choose fragrance-free baby soap, lotion, and wipes when possible. Skip perfume on or near babies. Use simple products with short ingredient lists, and avoid products that list fragrance or parfum.
If your child has sensitive skin, ask your pediatrician about the best gentle options.
