Please explain about monomer pooling which only ocuurs at the start of introducing pre-emulsion monomer into the reactor. It is surprising that it only occures when the reactor has been cleaned with NaOH solution and washed with water.
Hello👋, i want to mix 100 gram white petroleum jelly into 900 gram water. Can you please suggest me emulsifier and ratio of emulsifier. For transparent Imulsion.
Thank you for your question! Well, because they are not compatible so if nothing can keep them together (i.e surfactant), they would separate. Mind you that even after the addition of surfactants or the emulsifying agents, they might separate and more details are mentioned in the instability of emulsions video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9GBSDwXc50M.html
Hey Brandon, Thank you so much for asking. Well, for w/o emulsions the surfactants would orient such that their hydrophilic heads are within the water droplets (the internal phase) and their hydrophobic tails are towards the external phase, the oil. Imagine having too many tails surrounding the droplets of the water throughout the oil. At a point there will mechanical hindrance because of the presence of the bulky tails.. Check the first figure here to see the orientation of surfactants in both emulsion types and relate to the point stated above: statics.scnu.edu.cn/pics/aoe/2014/0508/20140508114934248.pdf Hope this helps, if you need further clarification, kindly let us know and don’t forget to stay Fab 😃
