A sugar-alcohol-modified organopolysiloxane compound represented by formula (1) and processes for producing the compound. (In the formula, R1 represents a hydrocarbon group having 1-8 carbon atoms; X is a group represented by formula (2); Y represents —R4O(AO)nR5 (wherein AO is an oxyalkylene group having 2-4 carbon atoms, R4 is a divalent hydrocarbon group having 3-5 carbon atoms, R5 is any of a hydrogen atom, a hydrocarbon group having 1-24 carbon atoms, and an acyl group having 2-24 carbon atoms, and n is 1-100); R2 is any of R1, X, and Y; and a is 0-700, b is 0-100, and c is 0-50; provided that when b is 0, at least one of the R2s is X.) (In the formula, R3 is a divalent hydrocarbon group having 3-5 carbon atoms; and d is 1-2.)
