A microcapsule containing core material and a capsule wall, in which the capsule wall of the microcapsule comprises:
organopolysiloxane synthesized by polycondensing one or more compounds represented by the general formula (II):
RnSi(OH)mY(4-m-n) (II)
wherein, m represents an integer from 1 to 4; n represents an integer from 0 to 3; m+n≦4; R represents an organic group in which a carbon atom is directly connected to a silicone atom, and when n is greater than 1, each of the R groups may be the same or different; and Y represents at least one group selected from the group consisting of an alkoxy group, hydrogen and siloxy group, and when (4-m-n) is greater than 1, each of the groups Y may be the same or different; provided that compound (B) comprises at least one compound of formula (II) wherein m=2 or 3 and at least one of R group possesses affinity for at least one of a continuous phase and a dispersed phase;
a method for producing the microcapsule; and
a use of the microcapseile, for example for cosmetics are provided.
