EMULSION COMPOSITION, PRODUCT, REDUCTION METHOD OF CONTENT OF ORGANIC SOLVENT AND SELECTION METHOD OF EMULSIFIER

摘要

To provide an emulsion composition applicable to a product without depending on an organic solvent on an active ingredient oil, the product with such the emulsion composition, a reduction method of the content of an organic solvent in the emulsion composition and a selection method of an emulsifier.SOLUTION: An emulsion composition includes: an aqueous phase; an oil phase containing an oil satisfying the conditions of following mathematical formulas (1) and (2); and condensation polymerization polymer particles having a closed endoplasmic reticulum formed of an amphiphilic substance spontaneously forming the closed endoplasmic reticulum and/or a hydroxyl group. A mass ratio of an oil content in the composition to the content of an organic solvent being a good solvent to oils is 25 or less (including 0).SELECTED DRAWING: Figure 5
