Squeaky clean meets minty clean. Scented with peppermint essential oil for a cooling, refreshing wash. Our Castile soaps are multi-purpose and cost-effective—use them as a hand soap, body wash, shampoo, house cleaner and more. Plus, they’re plant-based and biodegradable (as we do).> About Castile Soaps Hailing from the Castile region of Spain, Castile soaps were traditionally made with olive oil. Today, most Castile soaps are made with coconut oil, which can dry out the skin—but ours are made with castor and avocado oils to hydrate. (Trust us, your skin will thank you.)
