摘要
在牙膏液相和含不同摩擦剂种类牙膏中添加定量的乙烯基甲醚/马来酸共聚物(PVM/MA),通过加速老化法研究牙膏液相和牙膏黏度、稠度的变化。添加PVM/MA后,不管是牙膏液相还是牙膏成品均表现出的更好的性能,且在不同的摩擦剂体系下呈现出更优异的黏度、稠度以及色度。由于PVM/MA螯合作用的贡献,可有效提高牙膏的初始强度、增加膏体强度,并能提高牙膏稠度,稳定和改善牙膏白度,尤其是钙盐(如碳酸钙、无水焦磷酸钙)为摩擦剂的牙膏。
A quantitative amount of vinyl methyl ether/maleic acid copolymer(PVM/MA)was added to the liquid phase of toothpaste and toothpaste with different abrasives.Then the viscosities and consistencies of the liquid phases and toothpaste were studied by the accelerating aging method.After adding PVM/MA,both liquid phases and toothpaste showed better performance,and different abrasive systems presented better viscosity,consistency and color.Due to the contribution of PVM/MA chelation,the initial viscosity,paste strength,consistency and whiteness of toothpaste can be effectively improved,especially for the toothpastes containing calcium salts(such as calcium carbonate and anhydrous calcium pyrophosphate)as abrasives.
