For children aged 2–5 years (toddlers and preschoolers), sodium sulfite is probably low risk in small, short-contact (rinse-off) products, but it is not the safest choice for leave-on baby or child products because there are rules limiting its use and only limited safety data.
If possible, choose products for your 2–5 year old that do not list sodium sulfite. If a product with sodium sulfite is used: prefer rinse-off products (shampoos, bath products), do not apply to broken or irritated skin, avoid using on the face or near the eyes, and do a small patch test on the inner forearm 24 hours before wider use. Stop use and call your pediatrician if you see a rash, swelling, hives, or any breathing trouble. If your child has asthma or a known sulfite sensitivity, avoid products with this ingredient entirely and check with your child’s doctor.
Watch for skin rash, redness, swelling, hives, or any breathing difficulty after use — limited reports of allergic reactions exist (source: U.S. National Library of Medicine). Some regulatory bodies and industry reviewers restrict or limit this ingredient in cosmetics and note data gaps and concentration limits (sources: EU cosmetics rules and Cosmetic Ingredient Review). Because of those use restrictions, certified or baby-specific products may avoid it; when in doubt, pick products without sodium sulfite for young children.
