5+ year old children • Skin contact product
For school-age children (5 years and older) this ingredient is usually safe when put on normal, unbroken skin. Most health reviews find low concern for long-term harm, but a few people have had allergic skin reactions.
If you use a product that lists Hydrogenated Castor Oil, try a small patch test on your child’s inner forearm and wait 24–48 hours before using it widely. Use products as directed, avoid applying to cuts or rashes, and rinse off if the product causes stinging or redness. If your child has known sensitive skin or a history of allergies, choose a product formulated for sensitive skin without extra fragrances.
Watch for new redness, itching, swelling, or a rash after using a product — there are published case reports of allergic contact dermatitis tied to this ingredient (see the human case reports 'Allergic contact dermatitis from 12-hydroxystearic Acid and hydrogenated castor oil' and 'Allergic axillary dermatitis due to hydrogenated castor oil in a deodorant' (2008)). Ingredient reviewers have also flagged possible irritation to skin, eyes, or lungs (Cosmetic Ingredient Review). Because it can also appear in food or additives, total exposure from multiple sources is possible (U.S. Food and Drug Administration). If you see a suspected allergic reaction, stop use and talk with your child’s healthcare provider.
