This is really easy basic recipe for beginners. I've used the recipe from GARTUR STITCH FARM. Don't forget to wear the protective goggles and gloves at all times!!
First you need all your appliances ready before you start the process.
450g coconut oil
450g olive oil
133g of lye (Sodium Hydroxide)
Up to 10g of essential oils of choice (optional)
A slow-cooker or a non- aluminium bowl for heating the oils
A digital scale
A stick blender
A wooden or metal spoon
Soap moulds (or an old cardboard box lined with parchment paper)
Gloves and sunglasses or eyewear
A large bottle of white vinegar for neutralising the lye mixture if it spills on anything.
Start by melting your coconut oil. You can do this in the microwave or in a pan.
Carefully measure the lye and water separately.
Pour the water into a bowl or large glass jar. With gloves and eye protection, slowly add the lye to the water. NEVER ADD THE WATER TO THE LYE (this is really important). Stir carefully with a spoon, making sure not to let the liquid come in contact with your body directly.
As you stir, this will create a cloudy white mixture that gets really hot. Let this mixture set for about 10 minutes to cool. It should become clear and not cloudy when it has cooled.
When you have your melted coconut oil, pour it into a bowl and add the olive oil.
Slowly pour in the water and lye mixture and stir.
Quickly rinse the container used for the water and lye mixture out in the sink. I rinse well and then re-rinse with white vinegar to make sure all Lye has been neutralized.
Use the metal or wooden spoon to stir the lye/water mixture into the oil mixture in.
Once it is evenly mixed, use the immersion blender to blend for about 4-5 minutes or until it is opaque and starting to thicken.
If you are going to use essential oils for scent, add them now.
Quickly and carefully spoon into moulds. Any container will work. I am using silicon moulds, but I started just with empty milk cartons at first.
Cover the moulds with parchment paper and set in a cool, dry place, away from kids and pets. I cover my soaps with extra blanket or towel.
After 24 hours, using gloves remove the soap from the moulds and cut into bars.
Leave the bars somewhere to cure for about 4-6 weeks. You can test if they are done by sticking your tongue on them (yes this is really what you do) to see if the lye is still active. It will zing you like a battery if they aren’t ready.
