  Creating fragrance water

  Posted by Anonymous on January 25, 2017 at 12:57 pm

  I am trying to create rose fragrance water

  formulation : 
  
  oil phase
  rose essential oil : 0.1%
  polysorbate 20: 0.1%

  sodium benzoate 0.4%
  aqua QS

  but i am unable to get a transparent emulsion. the microemulsion comes out milky and foaming.

  I want to get rid of foam and want to get a clear emulsion.

  Please suggest.

  Using propylene glycol, we are able to get a clear solution with low foaming, but will it be enough to avoid ostwald ripening ?

  That is a case of try and see for yourself, I feel.

  I’ve offered my knowldge on this for making traditional type floral waters.

  Loading the water with other materials does not correspond to my idea of a floral water.

  @sjinesh the phenomenon you’re describing is phase separation - Ostwald ripening is something else entirely (dispersed phase becoming physically detached from the emulsion interface, which is extremely unlikely to happen in a system like this)
