Difference between Glyceryl Stearate and Glyceryl Stearate SE?
This is what I found online: Glyceryl stearate S/E differs from Glyceryl stearate in that it contains a small amount of sodium and potassium stearate. The addition of these components allows it to self emulsify and thus not require both the presence of oil and water.<div>
What does “Doesn’t require both the presence of oil and water” mean here?

I’m thinking that the phrase “doesn’t require both the presence of oil and water” in this context is a bit misleading. Glyceryl stearate S/E is a self-emulsifying version of glyceryl stearate, meaning that it can form an emulsion (blend oil and water) more easily because it contains additional emulsifying agents, like sodium and potassium stearate.
What it’s likely trying to say is that, unlike regular glyceryl stearate, which needs a separate emulsifier or both oil and water to create an emulsion, glyceryl stearate S/E has the ability to emulsify on its own due to the presence of those extra agents. However, it still needs oil and water to create an emulsion—it just doesn’t need extra emulsifiers to do the job. ??

thanks! I understood.

I will add that unlike glyceryl stearate, glyceryl stearate SE is anionic and also requires pH above 6 to form an emulsion. If you use it at acidic pH it will be clumpy.
