Second, many advanced techniques require that you work with a somewhat cooler soap base. Generally, our soap base will accept up to 1 cup of extra liquids per pound of soap. These extra liquids include scents and oils. I like to use beeswax. Wax will make the soap less clear.
Alcohol can make the soap more drying and impart an odor.
This will also make the soap softer. This will make the soap clearer and softer and can make it more sticky. How much to add depends on what you are adding. Generally, I recommend you experiment with about 1 teaspoon to 1 Tablespoons per pound of soap. Too much of a good thing can result in soap that's soft and causes lots of oily residue in the tub.
