I am formulating an emulsion with at least 10% of an ester. The rest of the oil phase is about 20% (not including the ester). I am using 4% cetyl alchol and 3% glyceryl stearate as the emulsifiers and stabilizing (tryig to ) the emulsion with carbomer. The issue is that the ester continues to destabilize the emulsion and falls out. Is this enough information to give me an idea of what to do? Thanks for any help!
