For toddlers (1–2 years), potassium hydroxide can irritate or burn the skin if it’s not used in a very low, well-formulated concentration. It’s allowed in some products but manufacturers are required to limit how it’s used.
Choose products made for toddlers and babies from reputable brands. Prefer rinse-off products (like shampoos) over leave-on creams that list potassium hydroxide. Don’t apply products with this ingredient to broken, red, or very sensitive skin. If you must use a product that lists it, do a small patch test on a less sensitive area first and rinse immediately if there’s stinging.
Avoid using on newborns and infants, avoid on broken or irritated skin, and keep away from the eyes. This ingredient is subject to formal use and concentration limits in cosmetics under EU regulations and industry safety reviews (Cosmetic Ingredient Review); those limits exist because of its irritation and caustic properties. Also, some product-verification programs restrict this ingredient unless manufacturers provide safety data—so prefer products that are explicitly formulated to avoid irritation.
