Steph's Opinion:

There is only ONE published study regarding the safety of this ingredient.  The MSDS sheet is also not made public. Although the database scores it as a 0, it doesn't necessarily mean that it's safe--it's just means that there is no data on the ingredient. So, while it doesn't have a history of being harmful, it also doesn't have a history of being safe.  If you have skin sensitivies, eczema, reactions, and such, I would personally suggest avoiding this ingredient.
