The present invention relates to a functional substance-releasing agent containing a silicic acid ester compound represented by formula (1) below, a process for producing the functional substance-releasing agent, and a composition containing the functional substance-releasing agent.
wherein R
1
represents a residue of an alcohol which results from removal of one hydroxyl group therefrom, the alcohol being selected from 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, a plurality of R
1
s may be the same or different, 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.
本发明涉及一种含有下式(1)所表示的硅酸酯化合物的功能性物质释放剂,以及制备该功能性物质释放剂的方法和含有该功能性物质释放剂的组合物。其中,R1代表从醇中除去一个羟基后得到的残基,所述醇被选择为具有2.0或以下的log P值的功能性醇和具有2.1或以上的log P值的醇之一,多个R1可以相同或不同,但所述硅酸酯化合物在一个分子中至少有一个残基是从具有2.0或以下的log P值的功能性醇中除去一个羟基得到的,至少有一个残基是从具有2.1或以上的log P值的醇中除去一个羟基得到的。
