Danish Study: MIT More Dangerous Than Thought

The Danish environmental authority is calling for a Europe-wide prohibition on the use of the preservative methylisothiazolinone (MIT) in cosmetics. The call arises from a study that shows a worldwide increase in allergic reactions because of MIT.

Above all, the experts criticize the use of MIT in leave-on products. Such products include creams or hair waxes that remain on the skin for a longer period. However, the substance is also used in shampoos and conditioners (rinse-off products).

The EU Cosmetics Regulation permits the use of preservatives in concentration of up to 100 ppm. Nevertheless, the members of the European Commission Scientific Committee warn that this value does not reflect safe usage. They suggest a threshold value of 15 ppm for rinse-off products.
