It is not the anti freeze properties you should be to worried about. It 
is for the rust and scale inhibitors that you use "anti freeze", or 
better: coolant. So use at least 50% of concentrate or 100% ready mixed 
coolant.

..................Also, using a lower % anti freeze mixture such as 25% instead of the common
practice of 50% will improve heat transfer. Water has a better coefficient of
heat transfer than anti-freeze. Do not use more anti-freeze than your climate
conditions dictate. Finally, install a thermostat that has a moving sleeve
that blanks off the bypass port in the head when the engine gets up to
operating temperature. Using a thermostat without a sleeve allows significant
amounts of coolant to bypass the radiator & simply return to the engine
un-cooled.
