Montanov L Emulsion failures & best stabilizer to use?
Hello,
I have been having the worst time with Montanov L and my emulsions staying together. No matter what I do, the oil phase begins coagulating the second I start adding the heated water phase, and I have tried to stick blend through the coagulation until a lotion forms but it never does. I have tried to switch between stirring by hand and stick blend, doesn’t work. I have tried emulsions with high heat, low heat, etc. I have read that many people have a hard time with this emulsifier, and Montanov 68. I use cetyl alcohol to help with the stability of the emulsion, add gum rheology modifiers, and I just don’t know where it is failing.
What are your methods to getting a secure emulsion? Are there additives that help prevent this issue?

Sounds like you are dealing with a phase inversion.
Add the oil phase slowly to the water phase…while under stirring.
It is hard to analyze a formula…when we don’t have the formula.
The best co-emulsifiers…are anionic…as long as there are no other conflicting ingredients. However…that will not address your phase inversion.

I didn’t post a recipe because I have so many. I am noticing that the larger my water phase, the better the chances of having a good emulsion. I use Sodium Stearoyl Glutamate as a stabilizer at 1% but don’t see much improvement. I have no cationic ingredients in the formulas.

It seems to me you’re trying to make an o/w emulsion, but adding the water phase to the oil phase. Am I getting it right? If that’s the case, try adding the oil phase to the water phase slowly, as @Graillotion suggested.

Yes, I was following the instructions on the website that said to add water to oil. So you suggest oil to water then? Ok, I will give it a shot!
