Patent ID: 8481776

Claim:
A functional substance-releasing agent, comprising a silicic acid ester compound represented by the following formula (1): wherein R 1 represents a residue of an alcohol which results from removal of one hydroxyl group therefrom, the alcohol being selected from the group consisting of a functional alcohol having a log P value of 2.0 or less and an alcohol having a log P value of 2.1 or more, and a plurality of R 1 s may be the same as or different from each other, provided that the silicic acid ester compound has, in one molecule, at least one residue resulting from removal of one hydroxyl group from a functional alcohol having a log P value of 2.0 or less and at least one residue resulting from removal of one hydroxyl group from an alcohol having a log P value of 2.1 or more; wherein the functional alcohol having a log P value of 2.0 or less is selected from the group consisting of trans-2-hexenol, leaf alcohol, 2-phenylethyl alcohol, cinnamic alcohol and anisic alcohol; and wherein the alcohol having a log P value of 2.1 or more is selected from the group consisting of 4-methyl-3-decen-5-ol, geraniol, citronellol, 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol and 2-ethyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-butenol.
