For children aged 2–5 years (toddlers and preschoolers): butylparaben carries moderate to high concern because studies show it can act like a hormone and there are animal studies suggesting effects on development. It can also cause skin allergy in some people. Because young children are still developing, it's safest to avoid it when you can.
Look for paraben-free products for daily skin care (especially for creams, lotions, and sunscreens that stay on the skin). If a product with butylparaben is the only option, prefer rinse-off products (like shampoos) over leave-on products, use a small amount, avoid applying to broken or irritated skin, and do a small patch test on a tiny area first. If you notice redness, a rash, or other skin changes, stop use and talk to your child's doctor.
Watch for skin redness, rashes, or irritation — there is strong evidence it can cause skin allergy in people (based on peer-reviewed studies). Also note that some regulators and scientific reviews (including the European Chemicals Agency and EU safety opinions) have raised concerns about hormone-like effects and recommend limits or restrictions, and some guidance has advised avoiding certain parabens in products for very young children. Because of these safety reviews and animal studies showing developmental effects at low doses, avoid routine use on young children and babies whenever possible.
