Prepare the work area:
Wear gloves, a mask and protective glasses. Perform the procedure in a ventilated area to avoid inhaling the fumes from the caustic soda.
Dissolve the caustic soda:
In a heatproof bowl, slowly add the 320g of caustic soda to the 500ml of water, never the other way around.
Stir carefully with a wooden or plastic spoon. The mixture will generate heat, so be cautious.
Filter and heat the oil:
If the oil is used, strain it to remove residue.
Heat it slightly (no more than 40°C) in a pot.
Mix the liquids:
Slowly add the caustic soda mixture to the oil, stirring constantly in gentle, circular motions.
Add the additional ingredients:
Add the chlorinated water, alcohol vinegar, baking soda, salt, and soap powder.
Stir until the mixture reaches a uniform texture and thickens.
Molding the soap:
Pour the mixture into heatproof molds and let it sit for 24-48 hours to harden.
Soap cure:
Remove the soap from the molds and let it dry in a cool, ventilated place for 4-6 weeks before using it. This time allows saponification to complete and ensures that the soap is safe for the skin.
Councils:

Customize your soap: Add essential oils, such as lavender or eucalyptus, to give the soap a fragrance.
