| Can bar soap be stored in the attic without melting? It probably gets to about 140 degrees up there. |

I keep a bar of soap in a plastic bag in my truck. I'd imagine it gets pretty hot inside when it's parked out in the sun. So far, it's never melted. Some bar soap doesn't age well though. Especially those small hotel bars. They seem to dry out and get crumbly with age. |

I vacum sealed (in 3's) a LOT of soap bars. My attic hasn't gotten to over 110, I imagine. (I checked on the A-C air handler last week up there, and it felt deadly) I took another 3 bars down last night and they were fine.
The brands that come in boxes, I took them out of the boxes before I sealed them. |

I own a company that manufactures soap, and I can tell you without hesitation that once the fats and oils have saponified, they undergo a chemical change. They won't melt. They can however dry out. Does drying out really hurt soap in any way? It still works doesn't it? You are in WV...  What kind of soap do you make?

OK, I will come back to this thread.
Bar soap is a generic term. There's two types of bar soaps, detergent and oleochemical (true soap). If you follow this, its basic chemistry and makes sense. An oleochemical (true soap) is made from animal or plant. It therefore contains fats and complex carbohydrates, that which we think of oils, that will dry with time. Detergents on the other hand are made from petrochemical sources and unless additives (oils) are added won't dry as fast. To put this in simple terms, face soap is probably true soap or at a minimum has softening oils added. Body soaps tend to be more detergent based. I don't store facial soaps in my vehicles, at least not on purpose. Tj |

I have been drying bars of soap on purpose. They seem to last longer. (One bar, dried accidentally before I moved from a house to an apartment, lasted the entire time I had a lease there, 4 years. This, was daily use in a bathroom to wash up after using the facilities.) So now I buy and open them (just tear it open and leave the rest of the packaging). My GF uses the hand-squirt soap in a bottle so that's what's deployed. Those things are just a way to get people to pay for soap more often. Twice or three times the price, and fewer washings out of it. I have let my female friends know that any "old soaps" they don't want I'll take. Now I have a large ziploc bag of fru fru soaps stocked up, for free! The perfumes are slowly dissipating as they are all open, and the bag not quite sealed.

| Soap is a wondrous thing, really. Its so necessary for a persons health and well-being. Its amazing how many people actually dont use it as often as they should. Some of the guys I work with stink like hell. Yeah, this is kind of a rant, but I'm a pretty clean feller, so working with people who dont bathe and keep their clothes clean kind of pisses me off. |

I have an old powdered soap dispenser in my office, left by a previous tenant. It has old fashioned powdered hand soap in it that is at least 10 years old if not far older. It's very dry and feels like sand but it still lathers fine, just takes a but more work. The bottom line is that although bar soaps will dry out and lose their scent, they don't really degrade over time. Anyone ever try making soap out of home made potash? |
