Saponification is the traditional process that turns olive oil into soap. It works by breaking down the complex oils using sodium hydroxide (lye) and transforming them into fatty acids, which then solidify into soap. Here’s the cool part—in our soap, 10% of the extra virgin olive oil isn’t converted. It’s trapped in its pure form, meaning your skin gets direct benefits from the natural oils, delivering all the good stuff like moisture and antioxidants right to your skin. Unlike many soaps today, which rely on harsh chemicals like sodium dodecyl sulfate (SLS) and then add things back in like collagen to make up for it, our soap is 100% pure and natural. The lye we use is less than 0.02%, leaving you with a soap that’s incredibly gentle. With Notis Castile, you’re getting the real deal—no chemical fillers, just pure olive oil goodness.
