Document Type and Number:

WIPO Patent Application WO/2001/013864

Kind Code:

A1

Abstract:

A water-containing powder composition comprising particles each composed of an aqueous gel as a core and hydrophobic particles with which the core is coated; and a process for producing the water-containing powder composition which comprises causing an aqueous phase ingredient to gel with a water-soluble gellant, forming the gel into particles each serving as a core, and then coating each core with hydrophobic particles. The composition is characterized in that it is excellent in production stability and storage stability and that the gel-based particles break to release water when used and pressed with, e.g., fingers. The water-containing powder composition is widely utilizable in cosmetics, foods, perfumes, agricultural chemicals, medicines, etc.
