How to check if this emulsion is o/w or w/o?
I did purchase a 25kg bag of glyceryl Stearate from India. Under the name Glyceryl stearate there is written o/w.
Now i am not sure if it is GMS or GMS se. As i have purchased it from a trader he aslo have no idea about what these things mean. I have made this cream sample from it and it is thick and stable for two days now.How can i check if this cream is o/w or w/o?
Ingredients of cream
Petrolatum %5
Sesame oil %1
Beeswax %1

I did add t table spoon of this cream in room temperature water and mixed. This is the result

GMS shouldn’t create an emulsion at all, so it migh be SE. But w/o or o/w consideration isn’t relevant.

@ngarayeva001 i saw water separation on 3rd day. The cream is not stable.

SE would hold it.. have you checked the ph? Even if it’s just GMS it’s still a useable ingredient. You need to pair it up with a proper emulsifier. Ceteareth-20 is a good option.

@ngarayeva001 pH is around 5.5
At what pH range GMS se would be stable? Evonik says 6.8-8.2

I tried at 7.2 and it worked, so your range sounds right.
