Along with many thousands of others, I have started to suffer from eczema, after being eczema-free for 53 of my 56 years, I have tracked down the culprit:  Methylisothiazolinone.  I have contacted the manufacturers of a number of products which have adopted this chemical as a preservative, and they tell me that scientists tell them that it is perfectly acceptable and harmless in a rinse-off product.  Forget that... I know that's not true.  MI in my shampoo gave me eczema across my eyelids.  Me, my sister, my cousin, my friend... I think the explosion of dermatitis caused by these chemicals is going to affect many people, especially those who look like car crash victims after contact with premises that have been painted with an MI containing paint.  I think you had better take your smug assurances and get back to the laboratory and find out what's going on.  Before a horde of angry consumers put companies which include these chemicals out of business by refusing to buy them.
