It never hurts to save money, and a good place to start is with products that you use daily in your home. Liquid hand soap is convenient and less messy than bar soaps, but it's also expensive, even if you buy the generic brands. Making your own liquid hand wash not only saves you money but also allows you to choose your own scents and ingredients.
Pour 1 cup of distilled or filtered water into a bowl.
Add 3 tablespoons of liquid castile soap, 4 to 5 drops of lemon or orange essential oil, and 4 drops of tea tree oil.
Blend the ingredients with a small mixer, or pour them into a blender and mix until all ingredients are combined. Pour the soap into a clean pump bottle.
Grate 2 cups of cured castile soap and pour it into a double boiler. Add 1 tablespoon of palm oil, 1/2 tablespoon of glycerine, and 3 cups of distilled water.
Stirring constantly, simmer the mixture over low heat long enough to completely melt the castile soap.
Add 1 teaspoon of vodka, and remove the boiler from the heat. Allow the mixture to cool slightly.
Add 1/2 teaspoon each of lemon, grapefruit, and eucalyptus essential oils, and mix well.
Allow the mixture to cool completely for several hours. Pour the mixture into two 236ml pump bottles. If the consistency is too thick, add a small amount of distilled water and stir well.
Tea tree oil provides antibacterial properties and will make any soap a germ killer. You may use any essential oils you prefer in place of the lemon, grapefruit, and eucalyptus oils.
