Resumen:
We examine the majorization properties of general thermal-like mixed states  depending on a set of parameters. Sufficient conditions which ensure the  increase in mixedness, and hence of {it any} associated entropic form, when  these parameters are varied, are identified. We then discuss those exhibiting a  power law distribution, showing that they can be characterized by two distinct  mixing parameters, one associated with temperature and the other with the  non-extensivity index  q. Illustrative numerical results are also provided.
