Our all-natural castile soap is made of water, organic sunflower, organic coconut oil, glycerin, potassium citrate, citric acid and organic essential oils. No harsh chemicals to irritate. No alcohol to dry. This is the perfect soap for kitchen or bath. Glass soap dispenser, 8.5 oz. (Please review the link below for the 16 ounce refills.) Consumer Reports named this soap one of 19 Top Wellness Gifts in November 2023. As a result, our glass supply chain has been challenged to meet demand. Round glass, blown in Spain, may be substituted and will contain 8.5 ounces of liquid soap. We apologize for any inconvenience.
