5+ year old children • Skin contact product
For children 5 years and older (school-age kids, children, tweens), Polyquaternium-73 is generally low risk when used on the skin or hair. Safety reviewers note only low-level concerns and possible irritation, not serious long-term risks.
Use products that list Polyquaternium-73 as directed. Do a small patch test on your child’s inner forearm before regular use. Avoid getting the product in the eyes and do not use it on broken or sore skin. If the product is a spray or aerosol, avoid spraying near the face or letting your child inhale the mist.
Safety reviewers (Cosmetic Ingredient Review) note this ingredient is allowed in cosmetics with some use or concentration limits and that there is a possible risk of skin, eye, or lung irritation. Watch for redness, itching, stinging, swelling, or eye irritation. If any of these happen, stop use and rinse the area; seek medical advice if symptoms are severe or do not improve. Do not apply to broken skin and keep products out of reach of younger children.
