An objective of the present invention is to provide an emulsion composition having excellent sense of use, capable of giving sufficient moister to skin, having good moister-retaining property continuously, and having both of low irritant property and stable preserving property even containing a sufficient amount of Vaseline for increasing obstructivity of skin and reducing moisture evaporation from skin. Another objective of the present invention is to provide an emulsion composition having repellent action against mite.An emulsion composition of the present invention includes (A) Vaseline, (B) lecithin, (C) glycerin, (D) water and (E) water-solvable polymer, wherein the content of the Vaseline (A) with respect to 100 mass% of the emulsion composition is 10~30 mass%, and the averaged particle diameter of internal phase of the emulsion composition measured by a dynamic light scattering method based on dynamic light scattering theory is 800nm or lower.本發明之目的係提供即使為了提昇皮膚的閉塞性、減低水分從皮膚蒸散而含有充分量之凡士林,其使用感仍優越,並可給予皮膚充分之水分、且具有持續又良好的保濕性,兼具低刺激性及保存安定性之乳化組成物。本發明之目的亦為提供具有驅避蜱蟎作用之乳化組成物。本發明之乳化組成物為含有(A)凡士林、(B)卵磷脂、(C)甘油、(D)水及(E)水溶性高分子之乳化組成物,其特徵為:該凡士林(A)之含量相對於上述乳化組成物100重量%為10至30重量%,上述乳化組成物之內相之根據動態光散射法且以動態光散射理論為基礎而測定之平均粒徑在800nm以下。
