My shampoo is killer

What a bloody great story to wake up to. It turns out that my shampoo has an ingredient in it that has shown to kill a rat's brain cells.

"The chemical, methylisothiazolinone (MIT), belongs to a class of compounds called biocides. These are used in the manufacture of many common household products and industrial water cooling systems to prevent bacteria from developing."

Granted, I'm not a rat. But look at the suffix in biocide! Do you really trust something that has -cide at the end?
