A common preservative used in baby wipes, named “allergen of the year” in 2013 by the American Contact Dermatitis Society, can now be found in a popular mouthwash.
The New York Times ran an article on methylisothiazolinone (MI), a preservative that deters the growth of bacteria but can cause severe rashes and skin irritations in people who are allergic to it. A European consumer safety group warns that MI should only be used in rinse-off products because there are “no safe concentrations” for leave-on products.
In spite of the warnings and a trend by personal product manufacturers to remove MI from products like baby wipes and lotions, Colgate-Palmolive uses MI in its Colgate Total Lasting White mouthwash.
