How to get plant oils to emulsify in spray formula?

I'm using apricot kernel oil and macadamia oil. I tried using polysorbate 20 but it didn't work. what could I use in a spray formula to keep the oil and water from separating?

Comments

  • Solubilisers are designed to incorporate only very small amount of oil into water. How much oil do you use?
  • 1.5% I've used other solubilizers and the plant oils don't seem to emulsify like the essential oils
  • Try PEG-40 HCO. It works in a concentration 4:1 with many oils, so you probably need 6% if you need clear solution.
  • would that emulsifier work for spray formulas?

    @BekaS:

    Research "microemulsions" ... there are a handful of emulsifiers developed specifically for this purpose.  For instance, you could try a combination of Coco-Glucoside and Glyceryl Oleate + Sucrose Stearate or as @ngarayeva001 pointed out Ppg-26-Buteth-26 (and) Peg-40 Hydrogenated Castor Oil ... BASF, Evonik & Croda all off emulsifiers specifically for development of microemulsion sprays and lotions

    Behentrimonium Methosulfate and Cetearyl Alcohol at 2% is a good alternative if you are willing to add water and a preservative.

    That would provide some conditioning too, if it's meant for a hairspray.
  • I've tried adding cetearyl alcohol to a spray formula before and it just made it cloudy and floated to the top and got hard
  • @MarkBroussard I got to this suggestion of yours ( Coco-Glucoside and Glyceryl Oleate + Sucrose Stearate ) searching for an alternative for a leave in solution/serum for hair. Would it work also with grapeseed oil, jojoba oil, almond oil and a few extracts? What is the % you recommend for around 8% oil?
    Thank you so much!
