GUIDELINES ON STABILITY TESTING OF COSMETIC PRODUCTS• Identify tests that will "accelerate and predict" the effects of normal conditions of storage and use. Where relevant, consider stresses, including temperature, that will enable assessment of product integrity under anticipated product exposure conditions. • Consider evaluation of critical aesthetic properties such as color, fragrance, texture, and flow, particularly after exposure ...
Test Method for Gas Separation Effect of MembranesSeparation membranes selectively separate gases, and the separation coefficient of gases is a key performance index in measuring separation effect. In this paper, by testing the permeability of nitrogen and carbon dioxide to a certain membrane sample, the separation ability of the sample to nitrogen and carbon dioxide is evaluated. The test principle, the parameters, appliion of the ...
CentrifugationCentrifugation Definition. Centrifugation is the process that uses centrifugal force for the separation of two liquids in a mixture. In this process, the denser component of the mixture migrates away from the axis and the lighter component migrates towards the axis. The process of centrifugation is carried out in a centrifuge, as shown in Fig 7.
Fractionation of CellsA finer degree of separation can be achieved by layering the homogenate in a thin band on top of a dilute salt solution that fills a centrifuge tube. When centrifuged, the various components in the mixture move as a series of distinct bands through the salt solution, each at a different rate, in a process called velocity sedimentation (Figure 89A). For the procedure to work effectively, the ...

Physical Properties of MineralsSeveral precautions are necessary for performing the hardness test. If you attempt to scratch a soft mineral on the surface of a harder mineral some of the softer substance may leave a mark of fine powder on the harder mineral. This should not be mistaken for a scratch on the harder mineral. A powder will easily rub off, but a scratch will occur as a permanent indentation on the scratched ...
