Are you wondering how to make olive oil soap? Fortunately, making this pampering beauty treatment is easier than you might think. Instead of paying sky-high prices for fancy soap at your local department store, you can create affordable olive oil soap in the comfort of your home.

About Olive Oil Soap

Olive oil soap, also known as Castile soap, has a long history. In fact, many people believe olive oil soap originated in Spanish Kingdom of Castile as early as 1567. Olive oil soap is created by mixing olive oil with lye, then adding colors and fragrances. Some people also like to add moisturizers such as glycerin to their homemade olive oil soap. Although it is slower to lather than other types of soap, olive oil soap is very mild. This makes it a great choice for people with allergies or sensitive skin.

Traditionally, olive oil soap was made with pure olive oil. Today, however, many people prefer to make their Castile soap with a mixture of oils. Soap made from 100 percent olive oil often has a lather that is slightly slimy. Oils that can be added to castile soap include:

  • Palm oil for hardness
  • Canola oil for creaminess
  • Coconut oil for a rich, bubbly lather

Choosing the Right Type of Oil

When learning how to make olive oil soap, it's important to understand what qualities are desirable in the oil you choose. Although high grade olive oil is recommended for cooking, a lower grade oil actually makes better soap. Lower grade oils work better for saponification and are also more cost effective. Instead of searching for extra virgin olive oil, look for products labeled as pure or pomace grade.Since the olive oils used for soap making are edible, you can generally find supplies for your project at your local grocery store. If you are planning to make a large quantity of soap as part of your home-based craft business, however, Olive Oil Source allows you to purchase olive oil in bulk.
