For infants (6–12 months), calcium hydroxide can irritate the skin, eyes and breathing. It is not a common cancer or developmental concern, but it can cause burning, redness or eye injury if it touches the face or broken skin. Because babies have very sensitive skin, this ingredient should be used very cautiously or avoided.
If you see this ingredient on a baby product: choose products made for babies that list safe low concentrations; avoid products with it on the face, diaper area, or on broken or raw skin; do a small patch test on an area of clean skin and wait 24 hours; if you get any stinging, redness, blistering or eye contact, rinse with plenty of water and stop use; for any breathing trouble, severe pain, or lasting eye injury, seek medical care right away. Keep powders or concentrated forms away from baby and never let the baby inhale dust.
Do not use on broken skin, near the eyes, nose or mouth, and do not let the baby inhale powder. Sources noting the irritation risk and use restrictions include chemical safety guides and cosmetic safety reviews (listed in safety literature such as the Pocket Guide to Chemical Hazards, the US National Library of Medicine summaries, and cosmetic regulatory guidance/CIR assessments). These sources classify calcium hydroxide as an eye/skin/lung irritant and indicate it is restricted or limited in cosmetic use unless formulated to avoid irritation.
