The escape speed at 150 Gm is about 42 km/s, namely $\sqrt{2}$ times Earth's orbit velocity of bout 30 km/s. This is vastly exceeded by the value of 450 km/s that you give, without reference. The conclusion is that the final whereabouts of the solar wind is not restricted by the Sun's gravity.

As to where the matter of the solar wind ends up, I would suspect in the Oort cloud but I give my conjecture for an expert opinion.
