Hello all. I've been trying to emulsify fractionated coconut oil into a water-soluble blend, but coming up a bit short. Using the HLB system I found that the oil has an HLB of 5. I then paired up two surfactants to match the HLB and blended together. The emulsion is stable for only a few hours and then separates. Any suggestions on what can be used? I am trying to make this into a sprayable formula so can't be too thick.
Fractionated Coconut Oil - 25%
Span 80 HLB 4.30 - 3.68%
Alcohol Ethoxylate HLB 13.10 - 0.32%
Water - Balance
I have tried bumping up the emulsifiers to 5% but still no luck. Thanks for any suggestions!
