I first used this soap when working at a building and asked maintenance person what soap was that. I lived in CO at the time and the water there is very hard (with minerals) and dries your skin terribly. She showed me the soap and I started using that in my home many years ago. This soap comes in large gallon size, which is cost effective, despite the higher cost of the product lately. Simply outstanding hand soap for hand washing in dry climate/hard water!If you wash your hands often and want a soap that will not over dry skin and cause it to crack and like a nice scent on soap, this will amaze you. Worth every dime paid for the 4-gallon (4x 1 gallon bottles) box! A+ product, I order it here all the time.
