Ascorbic Acid is a cleaning agent, commonly known as Vitamin C, that can be found in bath products, soaps and moisturizers. It alters the pH of a product to improve stability and functions as a chelator. The word chelator (pronounced "key-lay-tor") comes from the Greek word chele, or claw. Think of a chelator as a lobster claw that reaches out and grabs the minerals in soap scum or soils, to keep them from depositing on a surface. We use ascorbic acid in products to remove soap scum and mineral deposits that are caused by hard water. By binding to the soap scum or deposit, it allows them to be rinsed away.
