I'm wondering what's the best general practice when using gelling agents such as xanthan gum in typical emulsions (in all cases pre-dispersed in glycerin and added under high shear mixing for around 5 minutes).
1. Before emulsification: Adding the hot thickened water phase gradually to the the hot oil phase.
2. After emulsification: Emulsifying the formula without any gelling agent, and adding it right after having emulsified it (e.g. 5 min after).
3. At the end after cooldown: After having added all cooldown ingredients at the end.
I realize the devil may be in the details here and it could depend on the exact gelling agent and emulsifiers used, in this particular case I'm using Montanov L and Ultrapuregel.
