| Summary: | 碩士 === 嘉南藥理科技大學 === 化妝品科技研究所 === 100 === The use of silicon polymer make cosmetics not only the polymer given texture will give the smooth feel of the silicone oil,let the cosmetics have move more to enhance the added value. However, in order to give the cosmetic additional value, the cosmetic nature of the most important stability and stability must not be ignored. This study focused on silicon and polymer used in cosmetics, comfort and stability, and to explore the correlation between the rheological behavior of both.
This study investigates the rheological behavior of silicon and polymer used in the cosmetics to explore the correlation between comfort and stability. In this study, the silicon polymer formulations were added to the silicone oil and polymer thickener to comparing the correlation by high-temperature accelerated test, the centrifugal effect, the measured viscosity before and after aging to predict the stability of the cosmetics by more than analysis results, explore the differences of the rheological properties and stability of the polymer and silicone used in cosmetics.
Results:(1)Silicon polymer DC9040, DC9041 and DC9045, the viscosity shear rate 0.1 s-1~10.0 s-1 difference is more significant. The slope of the size of the order of the DC9041> DC9040> DC9045.(2) The DC9041 composition of monomer silicone oil is dimethicone, better make of silicone oil in cosmetic formulations for compatibility for dimethicone when due to increased volatility, the use of compatibility simply add a small amount of silicone oil can make the viscositychanges in the amount increase.(3) The addition of polymer in cosmetics than not presents silicon polymer is added which is given to the product touch and comfort given by the product viscosity drop in the painting coating.(4) Silicon emulsifier add only 0.1% can increase the stability of formulation.
Available by the results of this study(1) silicon in the use of indicators in cosmetics (2) silicon and polymer used in cosmetic formulations developed reference.
