Emulsification problem with Olivem 1000 & Mg ascorbyl phosphate
Does Magnesium ascorbyl phosphate affect emulsification using Olivem 1000?
I’m making a light Vitamin C serum/lotion but the emulsification is not working like it normally would. I’m heating the water phase to 80 degC and the oil phase to 75 degC. Using a hand held shear mixer (total quantity is only 100g) to blend. When I mix the two phases it separates just as soon as I stop blending. This happens several times… it just won’t mix. Then if I leave it a few minutes (maybe it needs to cool?) and try again, it can suddenly ‘catch’ and homogenise. I don’t know why it won’t emulsify straight away like it normally would with a cream, and I’m also worried the emulsion will not be stable given it’s not behaving like it normally would…
Water phase contains:
Magnesium ascorbyl phosphate 4.0%
Guar gum 0.1%
Hyaluronic acid HMW 0.2%
Hyaluronic acid LMW 0.2%
Oil phase contains:
Carrot oil 2.0%
Coco caprylate 4.0%
Olivem 1000 2.5% (yes I know this is low, but I want a thin lotion)
Cetyl alcohol 1.0%
Any advice as to what might be going wrong would be very much appreciated.
