New thread is fine by me. Why do people think it all ends just because MN only allows a 1000 posts on a thread?
Oh Bloomed, I somehow managed to miss that gem
. It all makes perfect sense now not.
I wasn't on the soap/shower gel thread (never used shower gel myself) but if we're talking pits, then I think it's a two-fold thing, most deodorants are silicon-based which creates an artificial seal on the skin, so it doesn't actually remove perspiration, it just locks it in and adds a touch of fragrance to mask anything that does somehow get through. If it's not removed properly (especially the extra strength, long lasting ones) it builds up (much like silicone can build up in your hair) and it's therefore not working as it should and storing up old transpiration under a nice warm little seal at the same time that positively reeks when it breaks through (think of it a bit like clogged pores). You have to view traditional soaps a bit like a solid oil cleanser, oil dissolves oil better than anything else but needs a surfactant to help it along (soap saponifies). Silicon has properties like an oil, so it tends to be more effective at keeping away that buildup as it actively breaks it down. I don't see why a shower gel with a heavy duty surfactant wouldn't do that job as well, but those tend to be the really drying types so probably not that popular and best avoided on those grounds.
I've always been a fan of traditional soap for the pits and a liquid cleansing oil for the rest of the body. French pharmacy is great for these, giant bottles that cost next to nothing. Usually marketed at eczematic skin, which is great as it doesn't dry your skin out or rob it of natural lipids, I rarely use body lotion.
