Proplyene Glycol (PG) in place of alcohol with great results as follows.
- The price - Alcohol can be 4X as expensive as PG.
- Alcohol (Enthanol) boils at 173.1°F(78.39°C); PG boils at 370.8°F(188.22°C)
- Alcohol like water will evaporate from the finished soap causing more shrinkage
- Alcohol is restricted in many areas(countries) and making is difficult to procure alcohol.
- 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
- Finally - people prefer (ethanol) Alcohol in a cocktail, instead of soap making process.
