For a 1-2 year old toddler, this ingredient is commonly used in small amounts in shampoos and conditioners. It is generally not linked to cancer or common allergies, but there are manufacturing and regulatory concerns (notably possible traces of acrylamide and some government restrictions). Overall it is a moderate-low risk for toddlers if used correctly.
Use products that are rinse-off (shampoo, body wash) rather than leave-on creams or lotions when possible. Pick formulations made for children or labeled for sensitive skin and from brands that state they control impurities. Rinse thoroughly after use and avoid putting products in the eyes. If you prefer extra caution, choose products that do not list this ingredient for your toddler.
Watch for skin redness, rash, or eye irritation after use — stop use if these occur. Be aware that regulatory reviews and industry safety panels flag possible contamination with acrylamide and place use or concentration restrictions (sources: Cosmetic Ingredient Review, EU cosmetics restrictions). Environment Canada has also noted concerns about non-reproductive organ toxicity and environmental toxicity. These are reasons to avoid leave-on products and to prefer well-made, rinse-off children’s products.
