| Summary: | 碩士 === 嘉南藥理大學 === 化粧品應用與管理系 === 105 === Rheology is a study on the flow behavior and deformation behavior of test items. Its application is very wide, there are a lot of product delivery process of success and failure and rheological nature has a very important relationship, whether in the food industry, chemical industry, cosmetics industry, biotechnology industry, materials science and medicine industry Affect the distance.
The next section of this study by the rheometer test include six kinds of vegetable oil and five kinds of body wash, five kinds of shampoo, five kinds of dishwashing, five kinds of lotion, five kinds of hand cream, five liquid foundation, Different products in varying the shear rate and stress, compared with its rheological properties.
The first part of the vegetable oil viscosity test properties of the results mostly Newton fluid, only palm oil is shear thinning, different proportions of olive palm mixed oil, the proportion of olive palm oil 1: 5 and olive palm oil 1: 3 is also showing high viscosity shear Thinning. The second part of the lotion shear rate test, shampoo are consistent shear thinning; because body wash composition is complex so it shows up shear thinning fluid; dishwashing at higher stress when the Newton fluid. The third part of the lotion test, hand cream, liquid foundation for the composition of complex shear rate are shear thinning.
