Oil dose not indicate that it needs to be the standard oil. Any liquid that is not miscible with h2o will probably be just Alright. Double emulsion is rarely used.
The sort of emulsion fashioned is dependent upon the hydrophilic-lipophilic stability (HLB) of the surfactant according to Bancroft's rule, with extra drinking water-soluble surfactants producing O/W emulsions
A system was developed to help in producing systemic choices with regard to the quantities and types of surfactants essential in secure merchandise. The procedure is called the HLB (hydrophile-lipophile stability) technique and it has an arbitrary scale of 1 – 18. HLB figures are experimentally identified for different emulsifiers.
