Emulsifiers for O/W Emulsions (Body Lotions)
What are suggested high performing emulsifiers for O/W emulsions (body lotions) that contain relatively high levels of oils and esters?
Are there any emulsifiers for O/W emulsions (body lotions) that perform equally or better than Emulsifying Wax NF? Ideally, the emulsifier would make the body lotion feel less greasy on the skin.
Any and all suggestions and comments are welcome.

The emulsifier you use depends on the HLB value of the oils that you’re using.

Grease fall concept that I tried and it works well. You choose the oils that you want on the cream. Then you choose different oils with different density.

You need a combination of low HLB and high HLB emulsifyer. It all depends on your oil phase. Cetearyl Alcohol, Cetyl Alcohol, Tocopherol are also part of your oil phase. Or just use polymers. You won’t need to calculate anything, just find a compatible one with % of your oil phase.

What the “high level” you are seeking to emulsify would be the relevant information here. As Perry informs, the polar nature of your oil load would dictate the chemical composition of your emulsifiers, based on the tried & true HLB system. However, as ngarayeva infers, should you have a really high level, then use a polymeric emulsifier such as Pemulen TR-2. That can accommodate up to 40% w/w as long as your formula has no electrolytes. As always mentioned here, put in the lab time and experiment.
