Abstract:
To build the evaluating method of the characteristic physical properties of the wetting mass, this study reported the preparation of wetting mass by adding water into microcrystalline cellulose, and using texture analyser texture profile analysis to test its physical properties, including hardness, adhesiveness, springness, cohesiveness, chewiness, resilience and so on, then finding out the better method and parameters. The method was evaluated and used to test wetting mass, which was made of microcrystalline cellulose of different types and polyvinylpyrrolidone. When running texture profile analysis whose trigger force was 1500 g, the relative standard deviation was under 10%, and the trend of every characteristic physical property tallied with the theory result by water ratio increase. Testing result of the same excipient with the same water ratio had a higher precision, while characteristic physical properties of wetting mass who was made of the same excipient with different water ratios and different excipients had a great difference. Using texture analyser to test physical properties of wetting mass could get a result which tallied with the theory by water ratio increase, and had a well precision, accuracy and sensitivity, and thus it could also evaluate the characteristic physical properties of wetting mass relatively well.
