I am fairly certain that Cool-Whip is pareve, and it contains casein
(lots). I also remeber that Coffee-Mate and similar non-dairy creamers
contain casein and are considered pareve. A friend of mine who is quite
religious used to make pareve ice cream (before there was Tofutti or Rice
Dream) using frozen Cool Whip.

Casein, by definition, is protein derived from milk. You can't get milk
protein from anything but milk. One seller of casein puts its milk protein
content of casein at 93%. If you can find a source of casein derived from
other than milk, I'd be quite surprised.
