When to add glycerin or humectants in LGN emulsion?
If we are making an LGN emulsion with high amount of 20% glycerin, is it better to add it fist in water phase or latter below 50°c to have maximum humectacy?
Or it doesn’t matter?

As long as they are evenly distributed throughout the water phase, it does not make a difference. However for ease of incorporation, I would suggest adding to the water phase before creating the emulsion.
