Ultrasonic emulsifier theory:
Emulsions are the most widely used forms of cosmetics, from watery fluids to viscous creams. Therefore, the discussion of emulsions is extremely important for the research and production of cosmetics, as well as for preservation and use.
Milk emulsion:
Preparation of the emulsion After determining its reasonable formulation, its emulsification technique is also extremely important. The preparation of cosmetics is mainly a mixing technique. Although the mixing technique is relatively simple, as a cosmetic, a variety of functions and properties are required, and it is not a simple matter to prepare a cosmetic such as an emulsion having excellent properties and stability.
Emulsification method
The emulsification method for preparing the emulsion, in addition to the nascent soap method, the agent in the water method, the agent in the oil method, and the oil-water mixing method:
Usually, the method is carried out in two containers of water and oil respectively, the lipophilic emulsifier is dissolved in the oil phase, the hydrophilic emulsifier is dissolved in the water phase, and the emulsion is emulsified in the third container (or in the running water). Within the line). Each phase is alternately added to the emulsion vessel in small amounts until one of the phases has been added and the remaining portion of the other phase is added in a trickle. If a flow system is used, the water and oil phases are continuously fed into the system in the correct proportions.
Application of ultrasonic emulsifier: 1. Life science: lysis, fragmentation, leaching of bacteria, viruses, spores and other cell structures, extraction of DNA from animals, protein extraction, pruning DNA/RNA/chromatin immunoprecipitation, such as cells Extraction of inclusions. 2. Material Chemistry: Dispersion, homogenization, emulsification, crushing and extraction of nanomaterials such as carbon nanotubes, graphene, titanium dioxide, silica, soil, etc. 3. Chinese herbal medicine: dispersion, extraction. 4. Accelerate chemical dissolution and accelerate chemical reactions. For example for chemical synthesis
