I didn't know they got that warm! Interesting!
So I wonder, how does (say) Dial do it? While I don't think Dial is nearly as good as my soap, it doesn't give my hands the same feel as new-uncured soap does. It's drying but not irritating. So is Dial curing soap for 4+ weeks in ginormous warehouses?
The crystal structure is determined by the milling/extruding/pressing. That's one of the main points of all that manipulation.
Traditional methods have no way to emulate that. But as I said in another thread recently, there is no real reason to speed cure. Just make soap more often and build a stock so you always have properly aged soap to use.
I requested a tour of local natural soap manufacturer's factory and was told they don't offer tours. I bet anything the soap is made from Asian noodles...and not the delicious kind.
Interesting. Is that why some soap is "triple-milled"?
So the milling extruding process speeds up the crystallization? We're guessing?
To be fair, they may not be allowed to have tours b/c of insurance. The Golden Flake potato chip company in my area used to do all kinds of field trips, tours, etc. It was one of the most fun field trips we did during school - lots of samples! But they had to discontinue it for liability purposes.
...chemists actually measure the different types of crystal structures, know the properties created by the different types, and do their best to tailor the soap production process to make the kind of product they want...
No, that's a common but false assumption. All evaporation does is just that, evaporate the liquids. Curing is a chemical change within the soap structure itself, and nothing but time can make that happen.That means that probably not with a dehydrator, but something that can speeden up the evaporation process may help with the curing?
This was actually my mistake. What I meant was an oven.
In case the temperature reduces, it makes the pH increase. Also, in case of pure water, the pH recorded at 0C was 6.14 and the pH recorded at 100C was 7.47
FYI, this thread is over 4yrs old, and the person you quoted hasn't been in here since then, so is not likely to see your post.I think you got the temp/pH backwards. pH of water at 100C should be 6.14 and 7.47 @0C.
And to be clear, (pure) water is still neutral at a pH of 6.14 and 7.47 at those temps. Changing the pH by changing temperature doesn't affect how basic the soap is. When we talk about pH=7 as neutral, that is assuming 25C (77F) which is considered "room temp" or standard temp in many sciences
I saw that and then realized I was reading the thread so others might be looking here too, so I posted anyway.FYI, this thread is over 4yrs old, and the person you quoted hasn't been in here since then, so is not likely to see your post.
