Q:

Looking for a comprehensive list of products free of Cl- Me+ isothiazolinone. My mother has a severe allergy to it and we are having difficulty finding products and manufactures have not been real helpful.

A:

Thank you for your inquiry.

Below you will find links to web sites which will be helpful to your mother in avoiding C1- Me+ isothiazolinone. However, unfortunately, I am not aware of any list of Cl- Me+ isothiazolinone-free products. In addition, I could not find such a list using a literature search. However, this is not uncommon. The information that we have on almost all contactants is related to substances which commonly contain these contactants rather than providing a list of substances which are known not to contain them. Unfortunately one must therefore read labels and employ the other strategies which are detailed for you on the sites identified by the links below.

Thank you again for your inquiry and we hope this response is helpful to you.
