Wondering what type of oils to invest in to make your own cold processed soap? These are the cold processed soap base oils I use. It’s easy to want to buy every type of oil available, however that would get extremely expensive, especially when you’re just starting out making soap.

Olive Oil

Good olive oil is key in making soap. I like to buy it from a warehouse type store, since most recipes require a large amount of olive oil. Some soaps are only made out of olive oil, however these take a long time to cure prior to using them. When using a soap calculator to formulate a recipe, I like to use 30% olive oil.

Coconut Oil

Coconut oil is another good base oil, I also like to buy it at warehouse stores. I tend to keep coconut oil at a little less than olive oil, such as 25% of the recipe. This is due to coconut oil being slightly drying to the skin. You can also order it on Amazon.

Hemp Seed Oil

Hemp seed oil is another good base oil, it contains essential fatty acids that can soothe skin. I like to use 15% in my recipe. I found this hemp seed oil on Amazon. I like this brand because it’s organic. Contrary to belief, hemp seed oil does not contain any CBD or THC.

Castor Oil

Castor oil is used in a small amount in soap to provide lather. I like to keep the percentage less than 10 %. I found this castor oil on Amazon. It also has a lot of skin benefits.


Lard, or pig fat, is a rather controversial ingredient. However, soap really needs a substantial oil to make a good bar. If you do not want to use lard, you can substitute with other butters. Lard is used in a large amount of the recipe, up to 30%. It makes a very creamy soap that really moisturizes the skin. I am a firm believer in using and appreciating the whole animal. This is the brand I use. One day I would like to get unprocessed fat from the butcher and attempt to render it myself.

In summary, whatever oils you end up choosing, make sure to research the skin benefits. I found adding a few specialty oils really helped my soap become a more quality product. Learning about the different oils has also helped my knowledge as a soap maker.
