The B-L symmetric SUSY model (B-LSSM) introduces a new $$Z'$$ gauge boson and two singlet scalars, which indicates there are more neutralinos in the B-LSSM comparing with the minimal SUSY extension of standard model (MSSM). These new neutralinos provide more dark matter (DM) candidates in the B-LSSM, we find that the super partner of the new scalar singlet can serve as the lightest supersymmetric particle (LSP) and be considered as a DM candidate. The properties of this new DM candidate are analyzed in this work. Taking into account the experimental constraints on Higgs boson mass, B meson rare decays and muon anomalous magnetic dipole moment, the numerical results are obtained and presented. The properties of new DM candidate in the B-LSSM satisfy the observed relic density $$\Omega h^2$$ and comply with the latest upper bounds on $$\sigma _\textrm{SI}^{\chi _1^0-n}$$ , and its mass is expected to greater than $$80\;\textrm{GeV}$$ approximately.
