For toddlers and young children (1-2 years): small amounts of acetic acid used in watered-down products (like mild toners or as a small pH ingredient) are usually low risk, but this ingredient can sting or irritate delicate toddler skin. Strong or concentrated forms are harmful and must never be used on a child.
Only use products made for babies/toddlers or labeled gentle for children. Do not use household vinegar or concentrated products on your child’s skin. Before full use, do a small patch test on the inside of the forearm and wait 24 hours to check for redness or irritation. Keep products away from the eyes and broken skin. If any stinging, redness, blistering, or swelling happens, wash the area with water and stop use.
Avoid any product that lists 'glacial acetic acid' or shows very strong concentrations — those are corrosive. The ingredient safety listing also notes handling hazards and some concerns about organ-system effects at higher exposures (referenced from Environment Canada) and guidance about concentration limits from agencies like the FDA and industry reviewers. Watch for skin irritation, and seek medical care if you see a severe reaction.
