I would assume that since they died as a fusion in a monster body - their dust essence would also be a fusion between both of their souls. So Chara's soul and essence became dust along with Asriel.

Monster dust when scattered on something - allows their essence to live on. In addition to the golden flowers, Asriel/Chara died while clutching Chara's empty body - I would assume much of their dust was scattered on top of it. Perhaps most of Asriel's dust fell on the golden flowers, while most of Chara's share of dust fell upon their own body. So when Toriel carried Chara's body back to the ruins to give it a burial - she actually carried a significant part of Chara's soul essence as well.

Having some of Chara's dust could explain why Flowey was such a powerful vessel for Alphys' determination experiment and why he was able to retain it without melting - he had some essence of a human's soul in him.

It could also explain why when Chara somehow becomes linked to Frisk when they fall through the barrier and lands on top of the flower bed growing from Chara's grave, their soul starts inhibiting some aspects of a monster soul - such as the inability to persist for very long after death. Notice how our SOUL breaks and scatters whenever we die, much like the monsters?
