  • Oil-in-water emulsion composition and cosmetics
    Patent number: 9901530
    Abstract: The present invention provides, without use of a surfactant, an oil-in-water emulsion composition and cosmetics having fresh and smooth feeling without powderiness in use, and having excellent emulsion stability by preparing a Pickering emulsion using a spherical polylactic acid powder. An oil-in-water emulsion composition is obtained as a composition containing (a) a spherical polylactic acid powder having an average particle size of from 0.5 to 1.5 ?m, wherein 90% by volume or more of the whole particles of the powder have a particle size of 3 ?m or less, (b) an oil phase component, and (c) an aqueous phase component, and containing substantially no surfactant. Desired cosmetics are obtained by using the oil-in-water emulsion composition.
