A saccharide residue-functional organopolysiloxane containing at least two monosaccharide or polysaccharide groups per molecule in which a specific site on the monosaccharide or polysaccharide is bonded to silicon through a thioether bond. Also, a method of preparing the saccharide residue-functional organopolysiloxane, comprising condensing a saccharide residue-functional metal thiolate compound wherein the metal is an alkali metal atom or alkaline-earth metal atom, and an organopolysiloxane containing groups having the formula —R 2 Q wherein R 2 is C 2 to C 10 alkylene, and Q is a group selected from halogen atoms, C 1 to C 10 alkylsulfonate groups, and C 6 to C 20 arylsulfonate groups. |
