PROBLEM TO BE SOLVED: To provide a solubilization composition which is excellent in transparency stability even when stored for an extended period, which has an excellent commodity image, which has high safety, and which can obtain high evaluation in a market, to provide a solubilization enhancer with which such a solubilization composition can be prepared, and to provide a solubilization enhancer composition formed by dissolving the solubilization enhancer in an aqueous solvent.SOLUTION: A solubilization enhancer of a poorly water-soluble substance contains a gluconate as an active ingredient. A solubilization enhancer composition contains the solubilization enhancer and an aqueous solvent. A solubilization composition contains the solubilization enhancer composition, an anionic surfactant, a nonionic surfactant, the poorly water-soluble substance, and the aqueous solvent. The solubilization enhancer is suitably used for producing a composition containing the poorly water-soluble substance such as a flavoring agent, cosmetics, a toiletry product, a medical drug, or a quasi drug or the like.COPYRIGHT: (C)2014,JPO&INPIT【課題】長時間保存しても透明安定性が優れ、商品イメージが良好であり、かつ安全性が高く、市場において高い評価を得ることができる可溶化組成物、かかる可溶化組成物を調製し得る可溶化促進剤及び該可溶化促進剤を水性溶媒に溶解してなる可溶化促進剤組成物の提供。【解決手段】グルコン酸塩を有効成分として含有する難水溶性物質の可溶化促進剤、該可溶化促進剤及び水性溶媒を含有する可溶化促進剤組成物、該可溶化促進剤組成物、陰イオン界面活性剤、非イオン界面活性剤、難水溶性物質及び水性溶媒を含有する可溶化組成物。本発明の可溶化促進剤は、芳香剤、化粧品、トイレタリー製品、医薬品または医薬部外品等の難水溶性物質を含有する組成物の製造に好適に用いられる。【選択図】なし
