Glycerin Method

Hi,

I've been making LS for the past year using the Failor water/KOH method.  Now, I would like to try the glycerin method for a quicker trace.  My question is: Can the water in a water/KOH solution be substituted 1:1 with glycerin. I.e. if the calculator says 35oz of water is needed can I use 35oz of glycerin instead.

Yes, you could substitute

Yes, you could substitute glycerin for some or all of the water called for by our SBM Soap Calculator.

If you use our Advanced Calculator version and specify how much glycerin you wish to use, the Advanced Calculator will automatically reduce the water to be used by that same amount.

As glycerin is actually a form of alcohol, it speeds saponification as other alcohols would as well. Keep in mind, though, that too much glycerin can considerably reduce your finished soap's lathering ability.

i did not know that glycerin

i did not know that glycerin was alcohol-based of that it reduces lather. Good info; thanks, admin. 

i always substitute glycerin for water when I'm making liquid soaps and still get plenty of lather, tons 'o suds.

Question: So, when making cream soap, we mix the lye into the water, then add the glycerin, & then hit it w/ the stick blender, right?
