An aqueous vesicle dispersion having surface charge comprising (A) 100 parts by weight of at least one ethoxylate selected from the group consisting of polyoxyethylene castor oil ethers and polyoxyethylene hydrogenated castor oil ethers, (B) 3 to 30 parts by weight of at least one sorbitan polyester of long-chain fatty acid, and (C) at least one ionic surfactant. The components (A), (B), and (C) are dispersed in an aqueous medium in such a manner that the components (A) and (B) form vesicle particles in the aqueous medium and the components (C) provides a surface charge on the vesicle particles. This aqueous vesicle dispersion has an improved dispersion stability and adsorpability of the vesicle particles and can include a hydrophilic or hydrophobic effective component in a state isolated from an aqueous dispersion medium. The aqueous vesicle dispersion can be utilized in the fields of a humectant, a bath salt composition, and a release-controlled topical agent composition.
