I make this a clear distinction in my mind, not a complex or ambiguous definition like many people ascribe to it. When acting through non-attachment, the action is done for the JOY of creation. The joy of seeing yourself do the thing, the joy of seeing it created, etc.
I believe that only from this can something truly pure be created. Otherwise, it will be stifled and defiled by the filth of one's own neediness. And that sucks
