To make a successful batch of organic soap, it is important to use a base of oils that will be cleansing to the skin, as well as nourishing. Olive oil is just such an oil. When selecting an olive oil to use for soap making, look for one that is organically produced. Organic olive oil will not contain pesticides or herbicides, which could potentially irritate the skin. You can find organic olive oil to use for soap making at any health food store or natural market.
Pour 946ml of organic olive oil into a pot. Place a cooking thermometer into the pot to monitor the temperature. Heat the olive oil until it reaches 43.3 degrees Celsius.
Pour 227gr of lye into a glass. Add 473ml of water to the lye and stir well. Place a second cooking thermometer into the lye water. The lye will chemically react with the water and will create heat. When the lye water is 43.3 degrees Celsius, pour it into the olive oil.
Pour 1 tsp of an essential oil of your choice into the mixture. Stir the mixture with a wooden spoon until it thickens. This can take around 30 minutes.
Pour the mixture into a rectangular soap mould. Place the soap mould into a dark room for 7 weeks. This will allow the soap to cure and harden.
Remove the soap from the mould. Cut the soap into 1-inch thick squares.
