Castile soap ranks amongst the oldest known soaps, and its popularity is ever-growing because it’s versatile, inexpensive, gentle on skin, and eco-friendly. It derives its name from Castile, Spain, where olive oil is found in abundance and was used as the main ingredient in the original Castile soaps.
Making liquid Castile soap is an easy process, referred to as saponification – which means soap making (‘sapo’ is soap in Latin).
Saponification is a process of combining base oils with an alkali, leading to a chemical reaction that yields liquid soap. The main ingredients are plant oils, potassium hydroxide (an alkaline solution, also called lye), and distilled water.
At Clean Rebellion, we use only organic products in our Castile soap which we put through a thorough saponification and purification process to create a lush, natural soap your skin will love.
Olive oil comprises long-chain fatty acids that cause a moisturizing lather that’s gentle on your skin. That’s why we only use organic olive oil in our Clean Rebellion soaps! Plus, it turns out that the saponification process transforms coconut oil into a tough cleanser that isn’t as well suited for your skin.
Making olive-oil-based Castile soap is a simple process, but it must be done correctly to create a high-quality, effective product.
