Latest Patents

Hyon-Ho Baek's latest patents include a purification method of hydroxypropylmethyl cellulose phthalate. This invention relates to a method of preparing high-purity hydroxypropylmethyl cellulose phthalate through a simple crushing process. The process involves increasing the fluidity of the reaction product mixture by adding a fluidization solvent as a post-treatment process. It also includes spraying the mixture into water through a spray nozzle, which results in the formation of fine granular particles that prevent inter-particle coagulation. This method effectively removes phthalic anhydride reactant, free phthalic acid, and remaining acetic acid solvent.

Another significant patent is the preparation method of solvent-free water-dispersible hydroxypropyl methyl cellulose phthalate nanoparticle. This environmentally friendly method is advantageous for disintegration and dissolution when used as an enteric coating material. It involves obtaining suitable hydroxypropyl methyl cellulose phthalate (HPMCP) particles through an aqueous emulsification process and regulating the content of remaining electrolytes through an ion exchange process.
