Hello respected scholars
Kindly tell me which surfactant I may use to make stable O/W emulsion with kerosene. Also, tell me if I put also inorganic salts like concentrated Sodium chloride as well as very dilute MB in the same emulsion. Can it reduce stability of emulsion?
Thanks
In 20 ml of water purified on a household filter, 2 g of a mixture of pentol and OP-4 (oxyethylated alkylphenol) is dissolved in a 3: 1 ratio. Mix with 80 ml of kerosene on an ultrasonic disperser. The addition of salt will impair the stability of the emulsion.
Almost any surfactant in appropriate concentration will make an oil phase into an emulsIon. High salt concentrations are likely to destabilize the emulsion - this is called ‘salting-out’. BTW, there is no such thing as a stable emulsion - all emulsions are thermodynamically unstable.
Many thanks Dear Sir Yuri Mirgorod and Sir Alan F Rawle. Have a nice day.
