NoNo SUSY or SM particle can break any of the conservation laws. I don't think you can connect quintessence with the higgsino if memory serves me correct it is the fermionic superpartner to the Higgs boson and thus will have fractional spin. While quintessence is spin 0 (bosonic).

I will of course check that 

Edit confirmed each SM boson will have a fermionic superpartner under SUSY.
