Is there a reference for the fact that the functor of Kähler differentials is a left Quillen functor on the category of $\mathrm{CDGA}_k/B$? Here $k$ is a field of characteristic $0$, and $B$ is some CDGA. 

This seems easy to prove, but I would appreciate a reference in the existing literature. 

This is a [cross-post][1] from MSE.
