Q&A for How to Make Glycerin Soap

Use a hammer/mallet on the bottom of the pan.

Glycerin soap is not glycerin, but soap with the addition of glycerin. Glycerin (glocerol, propanetriol is not soap, but an alcohol, and will not harden into a bar.

Typically, a controlled amount of lye is added to liquid glycerin/glycerol so that it will harden after heating.

No, any alcohol with a high percentage alcohol content will be fine,

Yes, since there no lye is used. It hardens pretty fast. You need to work with it fast if you want to add additives such as color, herbs or toys.

Yes, these items can be added to the soap.

Wait for the first layer to set. Once the first layer is set, you can pour the other color, which should not be fuming hot.

Not now, but in the future, I would recommend using any alcohol like Everclear that doesn't have such a powerful smell.

No, because it will not harden.

Yes, it bubbles less than regular soap but it does make bubbles.

Yes! However, it will not work as well as a cleanser.

You can add leaves after melting glycerin, but the glycerin should not be very hot and fuming.

Yes, this does help with demolding if you're using a solid (not silicone/thin plastic) mold. Just be careful not to spray too much, or you'll find you have to wipe down the soap afterwards, or you might even get an uneven surface in your soap from uneven oil application. Try using something like coconut oil or shea butter if possible.

You can buy rubbing alcohol sprays at online candle/soap suppliers. You can also but wooden loaf moulds online, as well as differently shaped silicone moulds. If you are thinking of making soap cupcakes, you can find silicone moulds in most general stores.

You cannot make basic soap with a pH7, there is no such thing. Any substance that has a pH above 7 is considered to be basic.

No, it's for skin. Glycerin is commonly used to give the skin a “soft” texture after washing.
