Glyceryl Stearate Citrate conundrum
Hello all,
I’ve never encountered this with any other emulsifier.
I noticed when I use this emulsifier the creams keep gaining viscosity for months afterwards. Looks like it has a very pronounced delayed formation? The differences can range from a pourable lotion consistency a week after to a thick foot butter cream two months later, it’s that extreme.
Details:
1. I’m using it as a co-emulsifier. Currently it’s paired with mon 68, plus cetearyl alcohol.
2. Have tested with it on its own, same issue only much more pronounced.
3. I cool the cream under an overhead stirrer. Have tried with a cold water bath and without.
4. Issue is also more pronounced when there are more butters in the oil phase, which leads me to believe it’s a slow structuring issue.
5. I discounted all other possible causes. No evaporation (samples are in a glass jar with screw on lids). Also repeated the test about 30 times.
Is this a known issue? It must be something in my method that needs to be adjusted to speed up things?
Thank you for any advice.

Can you share the formula or at least the other ingredients in it?

Sure. It happens in all sorts of combinations but this is my latest test that had this happen:
Oil:
8.5 sunflower oil
4 shea
6 CCT
1.5 cetearyl alcohol
3.5 montanov 68
1.5 glyceryl stearate citrate
Water:
3% glycerine
Rest water + 1% preservative
