Treating leather with PEG vapors

At the moment I am working on an African leather bag. It is really
dessicated and brittle, and I would like to resoften the material. I
recently heard about a treatment using PEG vapors. In fact the
object is placed in a embedded box containing a solution of PEG in
water/ethanol. This solution will turn to vapor and impregnate the
leather at the vapor saturation pressure.

Does anyone have written articles or could anyone give me more
information about this method ?
