Safe for preschoolers to use Methylchloroisothiazolinone?
ℹ️General Overview
For children 2–5 years (toddlers and preschoolers): this preservative can cause skin allergies in some kids. The chance of a reaction is lower than for babies, but it still happens, especially in children with sensitive or eczema-prone skin.
✅What to Do
Avoid products that stay on the skin (leave-on) such as wipes, creams, and lotions that list this ingredient. Prefer products labeled for sensitive skin or preservative-free. Rinse-off products (like shampoos or body washes) are lower risk, but still watch for irritation. If you must try a product that contains it, do a small patch test on the inside of the forearm and wait 48 hours. Stop use and contact your pediatrician if you see redness, swelling, blisters, or persistent itching.
⚠️Warnings
Do not use on broken or inflamed skin. Government safety reviews and clinical reports (for example Health Canada, Cosmetic Ingredient Review, and published case reports) have noted allergic reactions in children and have placed restrictions on use in some products. Avoid baby wipes and other leave-on products that list this preservative. Watch for signs of allergic contact dermatitis: redness, itching, swelling, scaling, or blisters. This ingredient may appear under related names such as 5-chloro-2-methylisothiazolin-3-one or in combination with methylisothiazolinone.
