Abstract
A silicone compound is represented by the formula (1) and has a weight average molecular weight of 500 to 200000. A polyhydric alcohol-modified silicone compound can provide a stable composition (emulsified product, powder dispersion, etc.) having a silicone oil and other oil as a continuous phase. R1aR2bR3cR4dSiO(4-a-b-c-d)/2 (1) (R1 represents an organic group, R2 is a group represented by —Y—O—X (Y represents a divalent hydrocarbon group having 3 to 20 carbons and optionally containing at least one of an ether bond and an ester bond, and X represents a polyhydric alcohol-substituted hydrocarbon group having at least two hydroxyl groups); R3 is a monovalent branched type organosiloxane group represented by the formula (4); and R4 is a monovalent organosiloxane group represented by the formula (5) or the formula (6).)
