Basic 4-Oil Soap Recipe

User Rating 1 Star Rating (1 Review)


Here is a basic soap recipe with simple ingredients that makes great soap. I've made dozens and dozens of batches with this recipe, and use it as the basic recipe whenever I teach soap making classes.

Prep Time: 1 hour

Total Time: 1 hour


  • 6.5 oz. palm oil
  • 6.5 oz. coconut oil
  • 7.5 oz. olive oil
  • 1.3 oz. castor oil
  • 8 oz. water
  • 3.1 oz. lye
  • 1 oz. of fragrance oil or essential oil blend


Mix your lye solution first and set it aside to cool. Measure and heat your solid oils until completely melted. Measure and add the liquid oils to the melted solid oils. When both the lye and the oils are at about 100-110 degrees, slowly pour the lye solution into the oils. Stir with a stick blender, alternating short blasts with the blender and stirring. Mix the soap until it reaches a light trace. Add the fragrance oil. Mix them into the soap thoroughly. Pour the raw soap into your mold and let it sit for 12-24 hours until it has cooled off completely and is hard enough to cut. Remove it from the mold and slice into bars. Let it cure an additional 2-4 weeks.

Basic oil recipe....ethical?, Member tanyanne

I have been looking for a soap making recipe and was about to get my supplies ready when I did a bit of research on the different oils used. Palm oil cultivation is causing rainforest deforestation and the destruction of sensitive ecosystems and indigenious peoples way of life. There are ethical Palm oil plantations, and other options that everyone should be aware of. This recipe should be revised.
