This production method comprises: a step (1) for obtaining glyceryl glucoside by subjecting glycerin and glucose to a dehydration condensation reaction； and a step (2) wherein all the glucose that may remain in the product of the step (1) is converted to (2A) gluconic acid by being subjected to an oxidation reaction or (2B) sorbitol by being subjected to a hydrogenation reaction. It is preferable that metal ions such as alkali metal ions or alkaline earth metal ions are added during the steps. Consequently, a glyceryl glucoside-containing composition which contains glyceryl glucoside, glycerin and sorbitol or gluconic acid, and additionally preferably 100 ppm or more of metal ions is obtained. This glyceryl glucoside-containing composition has excellent moisture retention properties, while being suppressed in undesired coloring, preferably.
