Traditionally alcohol has been used as the solvent in making M&P soap. It works well and help produce a transparent bar, but it does some have some drawbacks. Many people have used Proplyene Glycol (PG) in place of alcohol with great results. Below a list of reasons why I prefer PG over alcohol
- The price - Alcohol can be 4X as expensive as PG.
- Alcohol (Enthanol) boils at 173.1°F; PG boils at 370.8°F
- Alcohol like water will evaporate from the finished soap causing more shrinkage
- Alcohol is restricted in many areas making is difficult to obtain.
- You may need a special permit to purchase large quantities for soap making
- You can purchase Specially Denature Alcohol (SDA) but these are also very expensive compared to PG
- PG allows the soap to be re-meltable
- And Finally - I prefer my Alcohol in a cocktail, not my soap
