发明名称 COMPOSITION FOR APPLICATION TO A MUCOSA COMPRISING A METHYLCELLULOSE
摘要 A composition designed for application to a mucosa comprises a tonicity-adjusting agent, a methylcellulose, and a liquid diluent, wherein the methylcellulose has anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups.

主权项 1. A composition for application to a mucosa comprising a tonicity-adjusting agent, a methylcellulose, and a liquid diluent, wherein the methylcellulose has anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups and the tonicity-adjusting agent is sodium chloride, potassium chloride, calcium chloride, a buffering agent, xylitol, glycerin, mannitol or sorbitol.
