0-6 month old newborns • Skin contact product
For infants (0–6 months) this ingredient is best avoided when possible. It’s a plastic-like film former with limited safety testing on newborn skin and some reports of irritation, allergic reactions, and possible contamination by harmful chemicals.
Prefer products made for babies that do not list this ingredient. If a product with this ingredient must be used, first check the brand’s safety testing and impurity controls, ask your pediatrician, and avoid applying it to large areas or broken skin. Use the smallest amount necessary and keep it away from the face, mouth, and nose.
Watch for redness, rash, swelling, fussiness, wheezing, coughing, or breathing changes after use — these can be signs of irritation or an allergic reaction. The caution comes from government and industry reviews that note possible contamination by methacrylic acid, acrylic acid, or benzene and reports of respiratory or immune system effects (sources: Cosmetic Ingredient Review, Environment Canada, Association of Occupational and Environmental Clinics, U.S. National Library of Medicine). If you see any of these signs, stop use and contact your pediatrician or seek urgent care if breathing problems occur.
