Olive oil is another ingredient I use when making soap and skin care products. Like coconut oil it is readily available at the grocery store and in my kitchen.
The definition of “castile soap” used to be soap that was made with 100% olive oil. Apparently through the years the definition has evolved, first to mean any soap that contained olive oil as an ingredient, and now apparently to mean any soap that contains only vegetable oils. I have seen soap that is made from 100% coconut oil labeled as “castile soap”. So in my opinion the term “castile soap” has absolutely no meaning, and the only way to know what you are getting is to read the ingredients on the label (if you can see them).
In soap making olive oil makes a creamy, conditioning and moisturizing bar. I have found that olive oil in the right combination with coconut oil makes the perfect soap. The proper ratios of these two oils can make a bar of soap with just the right degree of hardness, it is a cleansing soap that is creamy and lathers like crazy.
In skin care products olive oil offers vitamins A and E and has great moisturizing properties. Olive oil is also a great oil to infuse with herbs that can be beneficial to skin care.
