  • I’m leaning towards Polysorbate 20

    Posted by Trinity on August 13, 2015 at 10:31 pm

    I am looking to emulsify a small amount of essential oil
    into water for a fine mist spray.

    In my research I have found the following..  Polysorbate 20, Glycol Stearate & SE and
    Methylparaben.
      AquaEm = PEG-6 Caprylic/Capric Glycerides (and) Polyglyceryl 6 Dioleate, as well as a reply from the forum below ***

    I do not want to use alcohol and I will need to avoid
    having the product become rancid.

    I am asking for help because I do not know where to start
    and I do not want to spend a bunch of money on trial and probably a lot of
    error. :)  In addition, it gets very confusing as to what products are used for what application and which can be purchased in small quantities or without a lic.

    In a perfect world, the goal is a simple concentrate
    where the customer adds water and that’s it.  

    I can mess with ratios and viscosity and figure that
    out. 

    Thank You 

    *** For
    natural solubilizers I would recommend Polysorbate 20, Polyglycerol-4 Caprate
    or something like Sophogreen from Soliance or SymSol from Symrise.  
    The best results I have had have been with Polysorbate 20 (used at
    3:1 or 5:1) and Sophogreen (used at 10:1)

    Do you know the HLB of the oil your are trying to solubilize?

    Thank you for your question…. here is what I have found in research but it is “greek” to me.  

    “Oil & Tween20 molecular formula C58  H114 O26, HLB = 16.7.  Prep from different surfactant concentrations keeping oil consistent at 6%.
    Also, oil prepared with light liquid paraffin were found between 13.36 +- 0.36 and 11.5 =- 0.35.
    Not sure if this helps.  I don’t mind the research I just don’t understand much of it and finding exact numbers is a windy road.  
    Thank You

    Another article I found said the following….

     Tween80 was chosen to be used as emulsifier because it has a high hydrophilic and lipophilic balance value equal to 15 and favors the process of formulating oil-in-water type of emulsion.

    See this post we did on the HLB system.  Essentially, you have to find out what the required HLB of your oil is and choose a solubilizing ingredient that works in that range.

    Do you need to be “natural”?

    Thank You Bob for entertaining my inquery.  Yes I did see and read the the HLB post and frankly, It was too overwhelming for me as a lay person.  The answer to your other question is that I do not need it to be natural.  

    I just want to simply emulsify an essential oil into water for a spray.  I really tried to research before asking any dumb questions which is where I fell into this website.  I understand if you feel I am looking for some FREE formulation but, I am not.  
    I am just looking for a starting point, and a product I can buy in small quantities so I dont break the bank figuring out my formula.  
    Either way, thank you for your reply and even if you say…. start with this ….. it is more than any help I can comprehend from any of my internet research.
    Thank you again.

    What is the net percentage (wt/wt) of the Essential Oil?

    I was going to start with 2% and do not think I will have to go over 5%.
