Whoops, sorry, misread that.

comment Non-embeddable varieties
This is not exactly what you want, but there are results of the form: a variety $X$ admits an embedding into a smooth toric variety if and only if any two points can be contained in an affine open set which is the complement of a Cartier divisor. Sort of generalizing Kleiman's result about which things can be embedded into projective space. See the work of Wlodarczyk, Hausen, etc.

comment Blowing-up a point in the singular locus
You completely changed the question so that the previously accepted answer didn't make sense, I rolled it back. If you have a new question, you should post a different question.
