Centraliser of \Delta U$\Delta U$ in U\otimes U$U\otimes U$

Let U$U$ be a universal enveloping algebra of a simple Lie algebra g$\mathfrak{g}$ over C$\mathbb{C}$. What is a good reference for athe centralizer of \Delta (g)$\Delta (\mathfrak{g})$ into U \otimes Uin $U \otimes U$ ? Here \Delta$\Delta$ is the usual coproduct, the diagonal.
