Why does Gilette shaving cream have isobutane, propane, and Nonoxonol-9 as ingredients???

I just looked on the can!Why does Gilette shaving cream have isobutane, propane, and Nonoxonol-9 as ingredients???
As above, the alkanes are inexpensive propellants. The nonoxynol-9 is a nonionic surfactant with antimicrobial properties. So, it probably helps the foaming and is a preservative.Why does Gilette shaving cream have isobutane, propane, and Nonoxonol-9 as ingredients???
Environmentally safe propellents. Starting using about 20 years ago instead of harmful flourocarbons.
Isobutane and propane are propellants to get it out of the can as a foam. As for nonoxynol-9, that is a spermicide used in a lot of condom brands, but I think it's also for lubrication.
well, did you let some out of the can so you could taste it? How do you know it's not cherry whipped topping? LOL
