The present invention is based on the discovery of a stable water-in-oil-in-water double emulsion. The double emulsion composition disclosed may contain molecular complex of volatile compounds for example 1-methylcyclopropene (1-MCP). In addition, the double emulsion composition disclosed can provide prolong or controlled release of the volatile compounds.本發明是以發現穩定的水包油包水雙重乳液為基礎。所揭示的雙重乳液組成物可含有揮發性化合物,舉例來說,1-甲基環丙烯(1-MCP)之分子複合物。此外,所揭示的雙重乳液組成物可提供該揮發性化合物的延長或控制釋放。
