Abstract
The present invention relates to a composite particle comprising: at least one hydrophilic core particle; and a plurality of hydrophobic particles, wherein the surface of the hydrophilic core particle is substantially discontinuously covered by the hydrophobic particles. The novel composite particle according to the present invention can have surface active properties sufficient to prepare stable Pickering emulsions, and can maintain the surface active properties over a long period of time. The present invention also relates to a method for preparing the above composite particle.
