### Abstract

Let $L$ be a commutative Moufang loop (CML) with the multiplication group $\frak M$, and let $\frak F(L)$, $\frak F(\frak M)$ be the Frattini subloop of $L$ and Frattini subgroup of $\frak M$. It is proved that $\frak F(L) = L$ if and only if
$\frak F(\frak M) = \frak M$, and the structure of this CML is described. The notion of normalizer for subloops in CML is defined constructively. Using this it is proved that if $\frak F(L) \neq L$, then $L$ satisfies the normalizer condition and that any divisible subgroup of $\frak M$ is an abelian group and serves as a direct factor for $\frak M$.
