A concept of a slice of a semisimple derivation is introduced. Moreover, it is shown that a semisimple derivation $d$ of a finitely generated commutative algebra $A$ over an algebraically closed field of characteristic $0$ is nothing other than an algebraic action of a torus on $\mathop {\rm Max}\nolimits (A)$, and, using this, that in some cases the derivation $d$ is linearizable or admits a maximal invariant ideal.
