For babies 6–12 months, octisalate is not the best choice. It soaks into skin and has had rare allergy reports and some laboratory findings that raise concern about hormone and developmental effects. It is safer than for newborns under 6 months, but still worth avoiding when you can.
Keep infants out of direct sun, use hats and sun-protective clothing, and stay in shade during peak sun hours. If a doctor says your 6–12 month old needs sunscreen, choose a mineral (zinc oxide or titanium dioxide) product labeled for babies when possible. If you must use a product with octisalate: test a small patch on the baby’s thigh first, apply only to exposed skin (not near eyes or mouth), use the smallest amount needed, avoid broken or irritated skin, and reapply only as directed. Stop use and call your pediatrician if you see a rash, redness, swelling, or any breathing trouble.
Watch for skin redness, rash, swelling, or breathing problems and stop use immediately if these occur. There have been case reports of allergic skin reactions to octisalate (human case reports). Tests and reviews note that octisalate can be absorbed through the skin and may act as a penetration enhancer. Contamination with salicylic acid has been reported (contamination concern). Some safety reviews and regulatory assessments recommend limits on use or concentration (Cosmetic Ingredient Review; Japan restrictions), and government reviews raise concerns about endocrine effects (National Toxicology Program) and developmental/reproductive effects in animal studies (ECHA). Environment Canada has noted contamination and environmental toxicity concerns. If you have questions or your baby has a history of eczema or sensitive skin, check with your pediatrician before use.
