No, avoid using 50% isopropyl alcohol spray on the CPU.

Are you certain the remaining substance isn't water while butane serves as the propellant? If the mixture is truly equal parts IPA and butane/propane, I’d steer clear from using it on tech equipment since other hydrocarbons might damage different plastic materials.
It seems these containers are likely filled with a mix of water or hydrocarbons rather than a balanced blend. This could indicate they contain more harmful substances than beneficial ones, potentially causing more damage than help.
I wouldn't apply any spray to electrical components nor use anything other than 70% or 90% isopropyl alcohol with careful, direct application. If you can't simply wipe the surface with medium pressure air and/or a Q-tip/towel using isopropyl, it might not be worth cleaning. ^^
You might consider applying the substance to a paper towel first before wiping it down. I usually use about 90% isopropyl alcohol for removing thermal paste, placing it on the towel and then using it to clean. Directly pouring it onto the CPU isn't advised. Compressed air often uses these materials safely when used properly, but it's still best applied away from components. Would you find rubbing alcohol more effective and less risky? Its quick evaporation can reduce damage chances. Is it easy to find locally or costly in your area?
You shouldn’t apply any flammable substances to electronic parts, particularly aerosol propellants. If the label doesn’t mention electronics, avoid using it. Butane and propane are generally safe for plastics but produce lingering flammable vapors longer than isopropyl alcohol. It’s not worth the risk—propane is inexpensive, widely available, and proven safe. I’m unsure if you’re aiming to cut costs; this isn’t a reliable solution.
