BillA: you might be interested by Silkolene ProCCA.

Contents are:
Highly refined mineral oil: 40 - 50%
Diethoxyethanol: <5%
Fatty Alcohol ethoxylate: <5%
Sodium Sulphonate: 5 - 15%

So no glycols (your first criteria). As for its effectiveness (#2), hmale uses it: you might be familiar with his rig, that has a copper block (?) and a SS pump. He reports that the coolant is still completely clear, after four months, but that's all I know.
