Safe for preschoolers to use Quaternium 91?
ℹ️General Overview
For toddlers and preschoolers (ages 2–5), this ingredient is likely low risk when used sometimes in rinse-off or short-contact products. There are some lab and animal findings that suggest caution, so it’s best not to use it a lot or on damaged skin.
✅What to Do
If a product your child will use contains this ingredient: choose rinse-off items (like shampoos) over leave-on products, avoid using it on broken or irritated skin, do a small patch test on a tiny area first, do not apply near the eyes or mouth, and stop use and see a pediatrician if you notice redness, swelling, or persistent irritation.
⚠️Warnings
Watch for skin redness, itching, or rash after use. The caution comes from animal and lab studies that showed possible effects on fertility, hormone-related pathways, and nerve cells (see study titles such as “Quaternary Ammonium Disinfectants Cause Subfertility in Mice...”, “Exposure to common quaternary ammonium disinfectants decreases fertility in mice”, “Identification of Environmental Quaternary Ammonium Compounds as Direct Inhibitors of Cholesterol Biosynthesis”, and “Benzalkonium Chloride Disinfectants Induce Apoptosis...”). Because these come from animal and laboratory work rather than large studies in children, we recommend being cautious with frequent or long-contact use in young children.
