Abstract: The invention aims to provide an emulsion composite which is excellent in safety and stability and which can easily be produced. 20 g of soybean oil and 2.4 g of glycerin were mixed by being stirred with a magnetic stirrer. The mixture was added to strong alkali ionic water to adjust the total amount to 200 g. The solution was subjected to primary emulsification in a boiling water bath at 12,765 rpm for a stirring time of 30 minutes using an autohomomixer. Necessary amounts of strong alkali ionic water and glycerin were then added such that the volume and the osmotic pressure became predetermined values. This sample was subjected to secondary emulsification at a pressure of 1,000 bar with 40 pass times using a high-pressure homogenizer to prepare an O/W emulsion (emulsion composite).

Abstract: This invention relates to a contact lens cleaner comprising microcapsules and a desired liquid or semi-solid containing the microcapsules, the microcapsules each being formed by laminating a wall material comprised of an inorganic polishing agent on the surface of a core material having elasticity. The present contact lens cleaner can effectively remove dirt or stain on a contact lens surface without having any adverse effect on the contact lens, and can be very easily removed by washing it away with water after use.
