The present invention provides a bicontinuous microemulsion composition, including: (A) polyglycerin group-containing organo(poly)siloxane shown by the general formula (1):
wherein R
1
represents an alkyl group or a phenyl group, R
2
represents a group having a polyglycerin structure shown by the formula (2) or the formula (3), R
3
represents R
1
or R
2
, “a” is 0 to 6, “b” is 0 to 4, a+b is 0 to 10, and at least one of R
3
is R
2
when “b” is 0:
wherein R
4
represents an alkylene group or an aralkylene group, “c” is 0 to 10, and “d” is 2 to 6; (B) silicone oil having a viscosity of 20 mm
2
/s or less at 25° C., volatile hydrocarbon oil, or ester oil; and (C) water. This provide a transparent bicontinuous microemulsion composition in which anionic or cationic surfactant, and water-soluble monovalent or polyvalent alcohol are unnecessary; and a cosmetic with excellent pleasantness of use.
