摘要/Abstract

摘要：

采用DV3T型流变仪测试无水牙膏增稠剂羟丙基决明胶、卡波姆的甘油溶液流变曲线,通过幂律方程拟合分析了相关的稠度系数、假塑性因子和黏度。试验数据显示,1.6%羟丙基决明胶与0.9%~1.0%卡波姆956的流变性能比较符合无水牙膏配方的要求。

关键词: 羟丙基决明胶, 卡波姆, 无水牙膏, 流变曲线

Abstract:

DV3T rheometer was used to test the rheological curve of the glycerine solution of hydroxypropyl gelatine and carbomer. The relevant consistency coefficient, pseudoplastic factor and viscosity were analyzed by power-law equation fitting. The test data show that the rheological properties of 1.6% hydroxypropyl gelatine and 0.9%-1.0% carbomer 956 meet the requirements of anhydrous toothpaste formulation.

Key words: hydroxypropyl gelatine, carbomer, anhydrous toothpaste, rheological properties
