I’m leaning towards Polysorbate 20
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%.

The gold standard for fragrance solubilizers is PEG-40 Hydrogenated Castor Oil.
