This work is focused on the exploration of the thermodynamics foundations of the matter creation scenario when a generalized form of the second law of thermodynamics for this scheme is implemented. In this scenario, we consider an expanding cosmology in which the produced particles are trapped by the apparent horizon. The scheme leads to phantom evolution but at first glance it lacks of physical consistency. However, we show explicitly that the inclusion of chemical potential into the description solves the thermodynamics issues of the model and determines the behavior of the cosmic fluid; in other words, the cosmic fluid now can behave as phantom dark energy or as quintessence one.
