🚨
NOT RECOMMENDED
Danger Score: 7 (Lower is safer)
Quick Answer: 8 Hydroxyquinoline Sulfate not recommended for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For newborns and babies under 6 months this ingredient is not a good choice for everyday skin care. Babies’ skin is more absorbent and the ingredient has rules and limited safety data for products that stay on the skin.

What to Do

Avoid products that list this ingredient on babies under 6 months. If a product is prescribed by a doctor, follow their instructions exactly. Prefer rinse-off products (bath cleansers) over lotions or creams that stay on the skin. If you must use a product with this ingredient on an older child, use only as directed and patch-test a small area first.

⚠️Warnings

Do not use on broken or irritated skin. Stop use and contact your pediatrician if you see redness, swelling, rash, or other signs of irritation. Authorities have restricted or limited its use in cosmetics (Health Canada, Cosmetic Ingredient Review) and one agency has noted possible concerns for development/reproduction (European Chemicals Agency). Data on safety for products that remain on the skin is limited (Cosmetic Ingredient Review). Also avoid ingestion — it is not allowed in food (U.S. FDA).

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.
