The purpose of the present invention is to provide a water-in-oil-type cosmetic composition and the like which prevents syneresis and the like and has good stability. The present invention provides a syneresis-preventing water-in-oil-type cosmetic composition characterized by containing, as an active ingredient, a compound that becomes soluble in water when neutralized. Additionally, a preferred embodiment of the syneresis-preventing water-in-oil-type cosmetic composition is characterized in that the compound that becomes soluble in water when neutralized is a water-soluble compound having a sulfone group. Additionally, the present invention provides a water-in-oil-type cosmetic containing the compound that becomes soluble in water when neutralized, a gelling agent, water, and a powder component, characterized in thatcharacterized in that the viscosity of the water-in-oil-type cosmetic is 7000 mPa.s or more.本發明之目的在於提供一種防止離漿等而顯示良好之穩定性之油中水型化妝料組合物等。本發明之離漿防止用油中水型化妝料組合物之特徵在於含有藉由進行中和而水溶化之化合物作為有效成分。又，於本發明之離漿防止用油中水型化妝料組合物之較佳之實施態樣中，其特徵在於，上述藉由進行中和而水溶化之化合物為具有磺酸基之水溶性化合物。又，本發明之油中水型化妝料之特徵在於，其係含有藉由進行中和而水溶化之化合物、膠化劑、水及粉末成分者，且上述油中水型化妝料之黏度為7000 mPa・s以上。
