    • An oil-in-water emulsion composition which gives a satisfactory use feeling, has excellent dispersion stability, and does not undergo surface roughening at the time of drying. A dispersion obtained beforehand by dispersing hydrophobized particles in an oil-phase ingredient and treating the mixture with a wet dispersing machine, e.g., a bead mill, is treated with a homomixer together with an aqueous phase to thereby obtain the oil-in-water emulsion composition. The composition is excellent in use feeling and particle dispersion after application to the skin. The dispersion stability of the particles is extremely heightened by using a specific dispersant in combination with a specific oil-phase ingredient. Incorporation of a salt-resistant thickener further improves the dispersion stability of the particles and can inhibit the composition from suffering sedimentation of emulsified particles or creaming with time. Use of succinoglycan as the thickener eliminates a tacky feeling. By plasticizing the succinoglycan, the surface roughening is eliminated.
    • 提供令人满意的使用感的水包油乳液组合物,具有优异的分散稳定性,在干燥时不会发生表面粗糙化。 通过将疏水化颗粒分散在油相成分中并通过湿分散机(例如珠磨机)处理该混合物而预先获得的分散体与均相混合器一起用水相处理,从而获得水包油乳液 组成。 该组合物在施用于皮肤后的使用感和粒子分散性优异。 通过使用特定的分散剂与特定的油相成分组合,颗粒的分散稳定性极大地提高。 加入耐盐性增稠剂进一步提高了颗粒的分散稳定性,并且可以抑制组合物随时间使乳化颗粒沉淀或乳化。 使用琥珀酰聚糖作为增稠剂消除了发粘的感觉。 通过增塑琥珀酰聚糖,消除了表面粗糙化。
