For a 6–12 month old baby, this ingredient is a cleansing agent that can irritate sensitive skin or eyes and may carry tiny amounts of manufacturing impurities. It’s not banned, but it’s not the gentlest choice for infants.
Use products made for babies or choose items labeled without this ingredient. If a product with it is used, keep it to short wash times, rinse thoroughly, avoid the face and eyes, and don’t use it as a leave-on product. If baby’s skin is dry, red, or easily irritated, switch to a milder cleanser.
Watch for redness, stinging, or eye irritation after use. Concerns come from industry safety reviews that report clear evidence of skin/eye irritation (Cosmetic Ingredient Review) and from government assessments noting non-reproductive organ system concerns (Environment Canada). Also be aware of potential contaminants reported in manufacturing (ethylene oxide and 1,4‑dioxane). If you see irritation or if the product label doesn’t say the product is purified or free of these contaminants, stop use and check with your pediatrician.
