RECIPE FOR HARD SOAP


















RECIPE FOR HARD SOAP


598 g coconut oil
296 g vegetable oil (Canola Oil)
30 g of ground beeswax (protects the skin and makes hard soap)
58 g avocado oil
150 g NaOH
368 ml distilled water

1. Make the water-sodium hydrochloride mixture.
We have taken all safety measures (gloves, long shirt, mask and do not breathe in the vapours!). We measure out the exact quantities. Put the distilled water in a plastic bowl that can withstand high heat and add the sodium hydroxide, little by little, stirring with a plastic or wooden spoon. Never pour water into the caustic potash and never use hot water. As you stir, the temperature of the water will rise and the water will become clear.

2. Make the oil mixture
In a large saucepan, add the oils and place it on a very low heat so that the oils mix perfectly.

3. Control the temperature of the oil mixture and the water-NaOH mixture.
Both must be at a temperature of 43 degrees Celsius. We put a thermometer on each and depending on if it wants to raise its temperature, we put it in a basin of hot water. If we want it to go down in cold water. So at some point we will get the temperature to be the same in both mixtures to mix them.

4. Combine the oils with the water - NaOH (gloves - mask are worn until the end of the process) Slowly pour the water-NaOH into the oils (without splashing) and stir gently with a spoon. Stir continuously. You can continue stirring for about an hour or so. But if we get a stick blender we will mix for about 10 minutes. We will stop mixing when the mixture starts to thicken and change color, and when we take a little bit with the ladle and pour it on the mixture, a line should form which will take a while to erase.

5. Pour the mixture into the moulds
In the moulds beforehand you should put petroleum jelly (so that the soap comes out easily when it is done). This mixture has been 80% soaped, put it into molds with a deep ladle. Caution is still the mixture is caustic!!!
(If you use pvc tubes at the bottom put a rap and tie some rubber band)

6. Cover the soap and leave it for 24-48 hours
When the molds are full I wrap them very well with lots of warm cloth. And I don't shake them again for 24 to 48 hours until the soap is done.

7. I take the soap out of the moulds
After 24 or 48 hours the soap will still be warm. Try taking it out of the mold if it doesn't come out leave it in the freezer for a while.

8. Leave the soap to set for 1 to 2 months

Let the bars of soap air harden. As time passes it becomes whiter and a white powder is formed. The longer it stands the better it gets.
