I am telling how much Essential Oil to put in Soap. Peppermint, Lavender, Tea Tree and Black Cumin. How to make Hot Process Soap with Essential Oils. Amounts and Percentages. My opinion ofcourse not anyone or any companies but mine thoughts and sharing to try to help you. I found this on a blog speaking from a ladies opinion “which is what i am doing here” so i wish to share it with you…….
Some Essential Oils can be quite irritating to the skin, so you should really educate yourself on their usage if you decide to use them. Essential Oils are more than just fragrance…many have medicinal properties than can interfere with medicines and medical conditions. Some common well known irritants include Clove, Cinnamon, and Peppermint. Some people are sensitive to Citrus oils. You can still use them in soap, just at a lower ratio. For most essential oils, I use 1 oz (by weight) per pound of base oils, which is a 6.25% rate. Some people would think that rate is too high, but in my experiences with safe essential oils, it works fine in CP soap. I however would NEVER use that much in a leave-on product and would keep it UNDER 3%. So for a 4 pound soap batch, I use 4 oz TOTAL essential oils. Many soapers use 0.7 oz essential oil per pound of soap. If I’m using an oil that can be irritating, I only use it at a rate of 0.25 – 0.5 oz per pound of oils, which is a 1.5% – 3% rate. It really depends on which EO you are using.
MP soap requires much less FO or EO as there is no saponification that needs to occur, which destroys some of the volatile constituents of essential oils.
