Grate or cut the soap base into small pieces to make it easier to melt.
Have all the ingredients ready and on hand.
Melt the soap base:
In a saucepan or microwave-safe container, melt the soap base over low heat or in 30-second intervals in the microwave, stirring each time to prevent burning.
Mix the vinegar and baking soda:
In a separate container, combine the white vinegar with the baking soda. Mix slowly, as it will generate effervescence.
Incorporate the ingredients:
Once the soap base is melted, add the vinegar and baking soda mixture.
Stir well until the mixture is completely integrated.
Flavor (optional):
If you want an aromatic soap, add the drops of essential oil of your choice and mix again.
Pour into molds:
Pour the mixture into the soap molds before it solidifies.
Gently tap the molds against the table to remove air bubbles.
Let solidify:
Let the soaps cool and solidify for at least 24 hours in a cool, dry place.
Unmold and use:
Once solid, unmold the soaps and store them in an airtight container or use them directly.
Preparation time: 15 minutes
Cooling time: 24 hours
Servings: Depending on the size of the mold, approximately 6 small soaps.
