    It will have similar properties but it isn’t the same. If you want it exactly the same, then no. If you don’t mind differences, then yes. So the overall answer is…maybe.

    @Perry
    It isn’t the same as what? Mineral oil or expensive sunflower oils?

    Mineral oil is made up of long chain hydrocarbons anywhere from C20 - C40 and beyond.

    Sunflower oil is made up of shorter chain hydrocarbons up to C10 - C22

    Sunflower oil is not chemically the same as Mineral oil.

    To me those two are drastically different, but in a very basic oil in water emulsion  consumer might not see any difference.

    Reasons not to use sunflower oil: 
    1) Relatively high polarity = emulsion is less stable (more important with w/o)
    2) It is prone to oxidation.
    3) Mineral oil reduces TEWL much better
    4) Mineral oil is hypoalergenic
    5) As anything that grows (and undergoes minimum processing) the batches of the material won’t be very consistent due to factors such as weather.

    Reasons to use sunflower oil:

    1) You can make soap out of it because unlike mineral oil it’s made of triglycerides
    2) Natural claims.

    @Perry thanks
    @ngarayeva001 do you know any website or research that has compared the TEWL reduction of different oils? 

    I had seen one long ago but now can’t find it.

    I haven’t seen one single source unfortunately, but I know that the best is petrolatum and mineral oil slightly lower.
