An object of the invention is to provide a novel sugar-alcohol-modified organopolysiloxane compound which can have hydrophilicity effectively imparted thereto with a raw material incorporated even in a smaller amount, by using a precursor having a sugar alcohol residue, and which provides a nonionic surfactant usable in a wide range of applications. Another object is to provide processes for producing the compound.
The invention relates to a sugar-alcohol-modified organopolysiloxane compound represented by formula (1) and processes for producing the compound.
(In the formula, R
1
represents a hydrocarbon group having 1-8 carbon atoms; X is a group represented by formula (2); Y represents —R

(wherein AO is an oxyalkylene group having 2-4 carbon atoms, R
4
is a divalent hydrocarbon group having 3-5 carbon atoms, R
5
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); R
2
is any of R

s is X.)
(In the formula, R
