Abstract:
A production method for a liquid high purity sugar derivative-modified silicone or a composition thereof is disclosed. The method comprises the steps of: 1) capturing hydrophilic impurities in solid particles by causing an impurity containing composition containing liquid sugar derivative-modified silicone and the hydrophilic impurities derived from a sugar derivative to contact the solid particles, the sugar derivative being a hydrophilic modifier of the sugar derivative-modified silicone, and the solid particles being able to capture the hydrophilic impurities; and 2) separating the sugar derivative-modified silicone and the solid particles. The method is useful for production of the liquid high purity sugar derivative-modified silicone and the composition thereof on a commercial scale.
