I was just wondering, is it ok to pack aerosoles like deodorant and shaving cream, in the checkin luggage? I'm not thinking of airline policies, but the actual physical effects of flying, because I believe while the cabin is pressured to about 8,000 feet, the hold is not pressured?

What I mean is, deodorants and shaving cream leak/explode due to the change in air pressure? I'd buy them once I get overseas, the only trouble is, once I'm in Europe on holiday, I'll be flying around a bit there and don't want to keep buying new bottles/packets etc every week!
