A production method of a liquid high-purity polyhydric alcohol derivative-modified silicone or a composition thereof, the method comprising: a capturing step of bringing into an impurity-containing composition containing a liquid polyhydric alcohol derivative-modified silicone and hydrophilic impurities originating from a polyhydric alcohol derivative, the polyhydric alcohol derivative being a hydrophilic modifier of the polyhydric alcohol derivative-modified silicone, into contact with solid particles capable of capturing the hydrophilic impurities, and then capturing the hydrophilic impurities with the solid particles and a separating step of separating the polyhydric alcohol derivative-modified silicone and the solid particles. An object of the present invention is to provide a production method of a liquid high-purity polyhydric alcohol derivative-modified silicone and a composition thereof useful for production on a commercial scale.
