Performance and shelf life of cream emulsion cosmetics
The readers who have yellow Pipette Tip the previous story of this series have shared the interesting stories about the pH measurement of cosmetics. For different types of cream and lotion cosmetics, the specific experimental details will be different. Turning more interesting Centrifugation experiment In the two tables above, we can see that among the physical and chemical indicators of cream emulsion cosmetics, a significant test is the centrifugation experiment, which has been proven to test the stability
performance and shelf life of cream emulsion cosmetics. See this little guy above?
That's right, what Xiao O classmate wants to say is it! First of all, the lightweight and flexible shape compact body will not take up too much space, coupled with ergonomic adjustment knobs and intuitive display panel design, more suitable for operators to complete independent and simple in the cosmetics laboratory Centrifugation experiment; Secondly, the full-featured nerve center dual safety control of adaptive imbalance monitoring system and overspeed detection can effectively avoid the safety accident of rotor flying, while the silent design can greatly reduce the noise of the centrifugation process, and create A quiet and comfortable experimental environment; Finally, the adaptable limbs adapt to 3 rotors + 7
different capacity centrifuge tubes (1. In this issue, we will look at one of the largest members of the cosmetics kingdom in the future: ream lotion products. B. The key methods, such as facial cleanser, body lotion, hair coloring lotion, etc. But don't look at this small bottle of lotion. Emulsification is a liquid-liquid interface phenomenon.

plus the ultra-long range setting, up to 99 Hours 99 minutes. Type, structure, and performance have a lot to do with the size (dispersibility) of emulsion particles and the quality (stability) of the emulsion. As a type of cosmetics in close contact with our skin, the quality of cream and lotion cosmetics needs to be strictly cont
