For children 5 years and older (school-age kids and teens), caprylyl methicone is generally low risk when used on normal skin in amounts found in lotions and sunscreens. Most safety notes are low-level issues, though contamination with other silicones has been flagged.
Use products with this ingredient the same way you would for other lotions: apply to clean, intact skin; avoid the eye area; test a small amount on the arm first (patch test) and wait 24 hours; choose products made by brands that test ingredients for purity if you’re concerned about contamination.
Stop use and talk to your child’s doctor if you see redness, rash, swelling, or eye irritation after use. The safety data shows possible contamination with other silicones (cyclopentasiloxane and cyclotetrasiloxane) and some animal studies reported irritation and hormonal effects only at moderate to high doses (from regulatory and scientific reviews). Because of that contamination concern, avoid this ingredient in products meant for very young babies (infants and newborns) and in products for raw or broken skin, and prefer brands that can show ingredient purity testing.
