A couple of other ingredients in Curlkeeper that I was curious about and found out this:

propylene glycol: "is able to lower the melting point of water, and so it is used as aircraft de-icing fluid. It is similarly used as automotive antifreeze."

DMDM Hydantoin: "A preservative that contains formaldehyde."

Gah! Who knew?
