For infants (0–6 months): Oleic acid is a fatty oil used to make skin feel soft. In most people it is low risk, but babies’ skin is thin and still developing, so it can be absorbed more easily and may cause irritation.
Avoid products that contain concentrated or pure oleic acid on newborn skin. Use only products made for babies or newborns. If using a product that lists oleic acid, apply a very small amount to a tiny area first and watch for 24 hours. Do not apply to broken, red, or irritated skin. Keep the product away from the baby’s eyes and mouth.
Watch for redness, rash, swelling, or any unusual breathing changes after use. Limited evidence of skin and eye irritation comes from the European Chemicals Agency, and one laboratory test showed a mutation result in cells (Environmental Protection Agency). Industry reviewers recommend limits on concentration and product types (Cosmetic Ingredient Review). Because of these findings and babies’ immature skin, avoid concentrated forms and stop use and contact your pediatrician if you see any reaction.
