For infants (0-6 months) β newborns and babies: this ingredient is risky. It can irritate or burn very young, delicate skin. Even if adults tolerate it, infants are more likely to get redness, soreness, or worse.
Avoid products that list potassium hydroxide on the label for babies under 6 months. If a product does use it, only use items that are clearly formulated and tested for newborns and state safe concentrations for infant skin. If you must use a product that might contain it (for example a cleanser), rinse the area thoroughly with water and avoid using on broken or irritated skin. Keep products with this ingredient out of reach of children.
Regulatory and safety reviews note use restrictions and potential for harm when not carefully formulated (EU Cosmetics Directive; Cosmetic Ingredient Review; EU GHS hazard labeling). Also limited medical reports show skin or eye irritation with exposure (U.S. National Library of Medicine). Watch for redness, blistering, persistent fussiness, or any eye contact β treat as a possible chemical burn and seek medical care right away.
