Ewax is a common name for an emulsification system. It usually consists of several emulsifiers. For example: emulsifying wax NF contains Cetearyl Alcohol and Polysorbate 60. In this case Cetearyl Alcohol and Polysorbate 60 are INCI. Bottom line all ewaxes are different. When you list ingredients, you should list INCI name, so that everyone understands what exactly you are using. In my formula above, I listed INCIs except for Paraben DU and T-resveratrol, but I specified a manufacturer.
