AI Technical Summary

Benefits of technology

This patented inventive medicine ink has been developed by adding certain chemical agents like glucansulfonates (cellulosic acid) instead of starches used as binders between sugar molecules together. It also includes colorants added during production to improve its printability onto hard surfaces. Overall, this new type of material provides better results than previous methods due to improved properties from both raw materials and manufacturing processes.

Problems solved by technology

The technical problem addressed in this patented technology is how to create a stable liquid medicine containing colorings without adding any substances like glue or binding agents into the formulation itself.

Abstract

The invention relates to edible medicinal ink which comprises pigments, solvents and a binder, wherein the binder is cellulose acetate phthalate and/or cellulose acetate succinate. The edible medicinal ink uses the cellulose acetate succinate and/or the cellulose acetate phthalate as the binder, and the pigments in various colors and pharmaceutically applicable solvents such as ethanol, propanol or butanol and the like are used as auxiliary materials, thereby forming the edible medicinal ink with excellent quality. The performance of the edible medicinal ink for word printing on the surfaces of medicinal hollow capsules, tablets and the like is better than that of similar products, and the edible medicinal ink can well meet the requirements on word printing on the capsules against differences of word printing equipment, differences in gelatin sources and quality, different companies, different regions and different formulas of the hollow capsules.
