Abstract:
1. An oil-in-water emulsion cream comprising: (a) between 0.3 and 0.8 wt % of a hydrophilic non-ionic surfactant, (b) water, (c) an oil ingredient, (d) a first higher aliphatic alcohol; and (e) a second higher aliphatic alcohol and/or amphiphilic substance, neither of which is involved in the formation of the α-gel, wherein the hydrophilic non-ionic surfactant, water and a first higher aliphatic alcohol, form an α-gel having a transition temperature of 60° C. or higher; the blend ratio of the hydrophilic non-ionic surfactant which forms said α-gel is between 0.3 and 0.8 wt % of the total amount of the oil-in-water emulsion composition; the molar blend ratio of the hydrophilic non-ionic surfactant and first higher aliphatic alcohol which form the α-gel is 1:3; the blend ratio of the second higher aliphatic alcohol and/or amphiphilic substance which are not involved in the formation of the α-gel is 1-10 wt % of the total amount of the oil-in-water emulsion, and the second higher aliphatic alcohol is the same as or different than the first aliphatic alcohol.
