• Partial transposition
• Separable state
• Entanglement

We study the stability of NPT property of an arbitrary pure entangled state under the mixture of arbitrary pure separable states. For bipartite pure states with Schmidt number n (n > 1) which is NPT, we show that this state is still NPT when it is mixed with no more than arbitrary pure separable states. This result is generalized to multipartite case.
