The dispersion relation for the near perpendicular propagation of the electromagnetic ion cyclotron wave, having a wavelength much larger than the ion Larmour radius, rL, and a frequency approximately equal to the ion cyclotron frequency, has been derived for a plasma consisting of a hot and cold ion component. The hot ions and electrons have been described by loss-cone distribution functions; an ordering of the parameters was used to derive the cold ion contributions. Two modes, one with an increasing frequency and another with a constant frequency can propagate in the plasma. The two modes interact resulting in an instability of the former in the wavelength range k-perpendicular rL = 0.4 - 0.6 (for nC/nH = 0) and from k-perpendicular rL = 0.5 - 0.8 (for nC/nH = 1.0) for a propagation angle of 70 deg. The instability of the mode is found to decrease with increasing cold ion densities and propagation angles.
