For infants 6–12 months (older babies and crawlers), sodium hydroxide in tiny, well-formulated amounts used only to adjust product pH is usually low risk. It is dangerous if present in concentrated form or if a product is not made to avoid irritation.
Choose products made for babies and from trusted brands that list baby-safe formulation. Avoid DIY or industrial cleaners. Do a small skin check: apply a little product on a small patch of your baby’s arm and watch 24 hours for redness or stinging. Stop use and rinse with water if your baby shows irritation. Keep any household or concentrated products with sodium hydroxide locked away and out of reach.
Do not use undiluted or industrial forms (corrosive ‘lye’) on a baby — these can burn skin and eyes (source: regulatory hazard labeling and occupational safety guidance). Some cosmetic rules and safety reviews restrict its use and say it must be limited or neutralized in finished products to avoid irritation (source: EU cosmetics rules and industry safety assessments). Watch for redness, blisters, swelling, coughing, or eye contact; seek medical care for severe reactions.
