Abstract

In this study, a new granular type mouthwash with equivalent antibacterial activity to marketed liquid type mouthwash was developed using a material called magnesium aluminometasilicate (Neusilin). This material adsorbs the surface of granules to improve the flowability of granules due to the formation of a eutectic mixture of the main constituents, which have improved flow properties and rapid disintegration time and little residue in the oral cavity. The characteristics of the granules were improved when the amount of Neusilin was 10% or more according to measurements of the granule properties, such as flowability. In addition, a disintegration test in artificial saliva and a sensory test in the human oral cavity were carried out to confirm the improved disintegration characteristics and sensory test results. The antimicrobial test confirmed similar antibacterial activity to that of the liquid oral cleanser already sold in the market. The granular oral cleanser composition prepared in this study can be used for the development of pharmaceuticals containing different drugs with similar characteristics as eutectic mixtures at the same time, which is considered to be useful in the development of medicines in the pharmaceutical industry.

본 논문은 새로운 과립형태의 구강청결제 개발에 있어 동등한 항균력을 가지면서 고형상에서 주성분간의 공융혼합물 생성에 따른 과립의 흐름성 부족을 개선하기 위해 과립의 표면을 흡착시키는 Magnesium aluminometasilicate (Neusilin)이라는 물질을 활용하여 흐름성을 개선하고 부가적으로 구강에서의 붕해시간 및 잔물감이 적은 특성을 가지는 새로운 과립형태의 구강청결제를 제조하였다. 제조된 과립의 흐름성, 밀도, 건조감량 등의 과립특성에 대한 확인을 통해 Neusilin의 양이 전체 과립양 대비 10%이상이 투입되었을 경우 과립의 특성이 개선되는 결과를 확인하였다. 또한 인공타액에서의 붕해시험 및 사람의 구강에서 붕해시간과 잔여물시험 등의 관능시험을 진행하여 보다 개선된 붕해특성 및 관능시험 결과를 확인할 수 있었으며 항균시험을 통해서 이미 시장에서 판매중인 액제형 구강청결제와 동등한 항균력을 보여주는 것으로 확인하였다. 본 연구를 통해 제조된 과립형태의 구강청결제 조성물은 공융혼합물로서 유사한 특성을 가지는 서로 다른 약물을 동시에 함유하는 의약품의 개발에 활용될 수 있어 제약산업의 의약품 개발에서 유용할 것으로 사료된다.
