I think it might have come the Wikipedia site for emulsifying wax NF or WiseGeek's entry on emulsifying wax NF (which is word for word what you see on the NDA site). But here's the thing...the INCI for Polawax is emulsifying wax NF, but emulsifying wax NF isn't necessarily Polawax. So you can't say that the ingredients for Polawax are the same as e-wax NF.
What is in Polawax? As I mentioned above, we don't know. There has been some speculation that it's cetearyl alcohol and polysorbate 60, but nothing has been confirmed.
Let's take a look at some of our emulsifiers again over the next few days! Join me tomorrow for more fun with emulsifiers!
