Soap is made by combining a lye (sodium hydroxide) and water mixture with various oils. A chemical reaction occurs and the oils are saponified giving you soap (no lye remains.) Each oil used in soap making has a different saponification value which means that each oil requires a different ratio of lye to water depending on the amount and type of each oil used. A soap calculator can help you to figure this out by allowing you to enter the amounts and types of oils you will be using and telling you how much water and lye to use. Different oils also have different benefits when making soap. For example, coconut oil makes a hard bar that has good cleaning properties while olive oil makes a soft bar with moisturizing benefits. The trick to soap making is to find the right combination of oils to give you a perfect balance for your needs. For our shampoo bar we are going to use: olive oil coconut oil castor oil tallow or Palm oil can be substituted for the tallow for a purely vegetable soap. Coconut oil-makes a nice hard bar that cleans and lathers well, but it can be drying so it is recommended to use no more than 30%. Olive oil-makes a softer bar that has wonderful moisturizing properties, but does not give much of a lather. Up to 50% is recommended. Castor oil-helps stabilize the lather created by the other oils. While it is recommended to use no more than 10% because too much castor oil can make your bar feel sticky, we are going to use slightly more in this recipe because the lathering properties really help when working the soap through your hair. I have never had a problem with my shampoo bar felling sticky. Tallow-makes a hard bar with great cleansing properties. Use up to 50%. (I rendered the beef fat from a cow we had butchered to make tallow. You can substitute palm oil in this recipe which has the same benefits as beef tallow. Just be sure to recalculate your ingredients to be sure your lye/water ratio is accurate.) Essential oils also make a wonderful addition to shampoo bars, but are not necessary. I have used a combination of tea tree, rosemary, and peppermint and also peppermint and orange. Both were lovely. https://wellnessmama.com/26682/shampoo-bar-recipe/
