In the purchase of emulsifier, there are many considerations for purchasing, and the emulsification effect is an important purchasing consideration. So what criteria is used to judge the emulsification effect? In response to this, a lot of relevant discussions on the Internet, our editor integrated a bit, today presented to everyone, you can refer when buying an emulsifier!
First of all, let’s take a look at some of the industry’s views on the evaluation criteria for emulsification:
- The most straightforward approach is to leave the emulsified emulsion for a period of time to see if there is oil or delamination.
- The emulsification effect has a certain relationship with the droplet size of the emulsion. The emulsification effect can be judged by measuring the particle size distribution!
- Look at the color of the emulsion wall, the blue color means the particle size is relatively small. This is just a very crude method, but there is still some guidance for the initial experiment.
- Measure the particle size and do a high-speed centrifugation test to see how stable the emulsion is.
- The emulsification effect is good or not, mainly depends on whether it will break the emulsion. Centrifugation and high temperature can accelerate the demulsification. If the centrifugation and high temperature do not break the emulsion, the emulsification effect is very good.
- Good emulsion emulsification effect: When the emulsification is complete, the oil phase and water phase should not see a clear interface. That is, the whole system is relatively uniform and translucent, and there will be no uneven droplets or particles of different sizes. Under the light microscope, the droplet size should be relatively uniform, 0.1-100um.
- My personal feeling is that the uniformity of the particle size of the emulsified droplet is more important than the particle size of the emulsified droplet. If the particle size of the emulsified droplet is large, the emulsification effect is not good, then in the limit state, the case of water-in-oil, the ratio of water to oil is 3:7, the droplet size is the largest, and the emulsification system is stable. But can this be said that the emulsification effect is not good?
Combining some common views in the industry and the experience of Yekeey’s many years of emulsifier equipment industry, it is necessary to judge whether the emulsification effect is good or not. The criteria for judging mainly include the following:
1, particle size and distribution
2, emulsion stability
With key criteria, the emulsification effect different factors of can be reflected in terms of standard values:
1. Using a professional particle size analyzer to determine the particle size and distribution of droplets in the emulsion;
2. Determination of zeta potential
3. Through the emulsion stratification index during storage (or under accelerated conditions):
The size and distribution of the particle size and the stability of the emulsion are important criteria for judging the emulsification effect. Especially for the cosmetics industry, with the deepening of the research and development of the cosmetic cream products, the detection of the particle size has become a vacuum. Key factors in the emulsifier technology considerations. The size of the particle size and the release of the quality of the cosmetic products are of great significance. In addition to purchasing a cosmetic emulsification device with good emulsification effect, it is recommended that you do a good job in particle size and emulsion stability testing.
