Quick Answer: 8 Hydroxyquinoline Sulfate not recommended for 6-12 month old babies when used in topical products. Monitor for any reactions in older babies.

ℹ️General Overview

For infants 6–12 months (infant, baby, newborn), this ingredient is not clearly proven safe for routine use. Regulators limit or restrict its use in cosmetics and safety for leave-on baby products is not well established.

What to Do

Do not use products that list 8-hydroxyquinoline sulfate on babies unless the product label specifically says it is safe for infant use or your pediatrician tells you to. If instructed to use it, choose rinse-off washes rather than creams or lotions that stay on the skin, avoid the face and mouth, do not apply to broken or sore skin, and use the smallest amount for the shortest time. Watch closely for any redness, rash, swelling, itching, or change in behavior and stop use immediately if you see any of those signs. For repeated use or diaper-area treatment, ask your pediatrician first.

⚠️Warnings

Health Canada and some European regulations place restrictions on how this ingredient is used in cosmetics. A cosmetic safety review panel notes that safety for products left on the skin is unknown. A European chemicals agency has flagged possible concerns for reproductive or developmental effects. There is some limited evidence of skin sensitivity. Because of these official restrictions and data gaps, treat this ingredient cautiously for babies and follow product labels and your pediatrician’s advice.

Safety Risk Labels

This ingredient has the following documented risks:

Fertility: A European chemical agency (ECHA) flagged this ingredient as a possible human reproductive or developmental toxin. That means it may harm future fertility or other reproductive health if people are exposed.
Brain Development: The same European agency (ECHA) identified possible developmental harm. Developmental toxicity can include effects on early growth, including the brain, so this is a real concern for young children.
Banned: Health Canada and EU cosmetics rules put limits or bans on its use in cosmetics, industry reviewers note strict concentration limits, and the FDA prohibits it in food. Multiple agencies restrict or disallow this ingredient in some uses.
Absorbed: EU workplace hazard rules set low allowed exposures and hazard labels for workers, which shows the chemical can be harmful with contact and may get into the body during handling.
