A new conservative replacing parabens – is it really a good idea?
A new conservative, Methylisothiazolinone, replacing the famous parabens in many cosmetics, is accused of causing skin allergies such as eczema.
Parabens, preservatives in cosmetics, suspected of being endocrine disruptors by binding to estrogen receptors, are now almost entirely banished from our creams, lotions and other shampoos.
And marketers do not hesitate to remind happily on the packaging of their products. A label with “paraben” is now a real selling point.
WHAT THE METHYLISOTHIAZOLINONE?
However, manufacturers have had to find another way to ensure the proper preservation of their products. And had no alternative but to turn to the methylisothiazolinone, a preservative used in hygiene products there twenty years.
Problem: this chemical is a known allergen dermatologists. In addition, to be as effective as parabens, it is necessary to use higher concentrations, which makes it much more irritating.
Dermatological days of Paris took place from 11 to 15 December 2012 were an opportunity for the teacher AnnickBarbaud, head of the dermatology and allergy unit of the University Hospital of Nancy, report a number of skin allergies in high progression.
MORE CONTACT DERMATITIS ON THE HANDS OR VISGE
“We are seeing more and more patients with contact dermatitis on the hands or face. This product is so volatile that some people suffer from breathing difficulties just when they are in a room where the floor was washed with a cleaner methylisothiazolinone, “says Dr. Barbaud, whose remarks were echoed by the NouvelObservateur.
The most sensitive of us have just scrutinized the labels of creams, shampoos, soaps, dishwashing liquids, etc., to avoid using products methylisothiazolinone.
