Is this safe for 0-6 month old newborns to use Methylisothiazolinone?
ℹ️General Overview
For infants (newborns to 6 months): not recommended. This preservative can cause strong skin allergies and rashes in babies, and has been linked to reactions from baby wipes and other products.
✅What to Do
Avoid products that list 'Methylisothiazolinone', 'MI', or similar names on the label for babies under 6 months. Choose plain, fragrance-free products made for newborns, or use water and an approved gentle cleanser. Do not use wipes or lotions that list this ingredient. If you must use a product, pick one specifically labelled as free of methylisothiazolinone. If your baby develops redness, bumps, oozing, or worsening eczema where a product was used, stop use and contact your pediatrician or a dermatologist.
⚠️Warnings
Watch for signs of an allergic reaction: redness, swelling, small blisters, oozing, or a sudden worsening of eczema at the area of contact. These concerns are based on human case reports linking baby wipes to allergic contact dermatitis and on government safety opinions and restrictions (for example Health Canada and the German safety authority) and industry safety reviews that document sensitization risks. Do not perform at-home patch tests on infants; seek medical advice if you suspect a reaction.
