We would like to highlight here the very recently emphasized properties of ultrahigh-energy interactions and to study their bearing on the analysis of the nature of the cosmic-muon charge ratio at ultrahigh energies. It is interesting to note that by combining the recently observed properties of all the relevant aspects of the problem and using the updated values of the necessary parameters, we can give a reasonably good description of the data even with the help of a phenomenological model for particle production of Rossi et al. and also with the induction of a hand-inserted value for moderate violation of Feynman scaling at ultrahigh energies. Our results on the muon charge ratio and some other observables will be compared with those of the quark-gluon string model of Erlykin, Krutikova, and Shabelskii, which is also a version of empirical theoretical model with scaling violation as a basic feature.
