[Problem]The present invention provides an oil-in-water-type emulsion composition which can be produced by directly emulsifying an organopolysiloxane having a high polymerization degree, contains substantially no oversized particle, and has a small average particle size. The present invention also provides: a method for producing the oil-in-water-type emulsion composition using a vertical batch mixer； and a use of a cosmetic raw material or the like which contains the oil-in-water-type emulsion composition.[Solution]An oil-in-water-type emulsion composition which is an emulsion containing (A) an organopolysiloxane having an overall viscosity of 1,000,000 mPa·s or more or having plasticity or a mixture thereof, (B) a surfactant and (C) water, wherein the component (A) is emulsified in water by the action of the component (B), the average particle size of emulsion particles falls within the range from 0.1 to 7.5 µm, and the content of emulsion particles each having a particle size 10 times or more larger than the average particle size is less than 5.0 vol%； and a use of the oil-in-water-type emulsion composition.
