Pure Castile Soap.
Ingredients: Olive Oil, Coconut Oil, Lye, Water, Essential Oils
This bar has lemongrass and other citrus essential oils. Nice clean fragrance. This soap is made to fit in shaving kits using bristle brushes. I will be completely honest. I do not shave. I do not remember the last time I did. I do not think you should either, but apparently some people like it. To each their own. I know other people who use this bar for the “s” word. I am not going to name them, but they have been very happy with the results. Just an FYI (if you are still reading) it makes a great bar for washing everything else if you prefer round bars.
How does soap work? Just a quick explanation since I used to teach science! There are two types of molecules to worry about here: hydrophillic (water loving) and hydrophobic (water avoiding). Most dirt, grime, and grease that will not simply rinse off is because it is hydrophobic and will not mix with water. Think about oil floating in water = hydrophobic. Your skin is made of non-polar lipids (fats/oils). Grime and grease made of lipids sticks to other lipids (your hand). Soap is made through a process called saponification. It involves lipids (fats/oils) and lye (NaOH). The lye changes the oils in the soap to a new molecule that is essentially a non-polar lipid on one end allowing it to stick to lipids (the grime and grease on your skin). The other end thanks to the lye is now polar. An ion with a charge that can stick to water (think magnets here). If one end sticks to the grease/grime and the other will now stick to water it can be washed away! This is why you need soap to wash off oil and grease and can not simply use water alone. Thanks soap.
