Just keep it in away from heat, that can cause the cream to break down. Keep the cream from exposure to air. If you want to decant, you might be able to use an airless pump bottle, similar to these.I recently bought a 500ml barber sized tube of Proraso green shaving cream & a 500 ml jar of the green pre/post shaving cream...Has anyone else ever used one of these bags or have any opinions they would like to share?
Things to avoid: leaving the cream on a sunny windowsill, in the trunk of a car, on top of the radiator, etc.
