Bubble Up or Cocamidopropyl betaine is a mild surfactant that comes from coconut oil, and is commonly used as a secondary foaming agent in liquid washes. We love it because it produces gorgeous "Hollywood" style bubbles in our bubble cake recipes. It can be used to foam boost body washes and bubble bath.
