Can a makeup airbrush be used for cake decorating airbrush?

Yes.

Cake decorating airbrushes and makeup airbrushes are very similar and function on the same principle.

They both use compressed air to spray a fine mist of liquid. The main difference is the type of paint or mixture being used.

Makeup airbrushes typically use water-based or alcohol-based paints, while cake decorating airbrushes use food-grade colorings or cocoa powder.

As long as the airbrush is properly cleaned after each use, it can be used for both makeup and cake decorating without any issues.
