Emulsion losing viscosity
New to the forum, first post.
I have an emulsion that I produced on 8/24 that is losing viscosity. I created an identical (within margin of error) emulsion on 8/31.
The emulsion from 8/24 has lost viscosity. Both emulsions sat side-by-side in a temperature controlled environment. The second emulsion is in an identical state as when I transferred it on day two.
They are creams:
66.6% H2O, 4% Glycerine w/xanthan gum
15% Oils (mct and shea butter with small percentages of jojoba and sweet almond)
5% olivem1000 with stearic acid, glyceryl stearate and cetyl alcohol that bring the emulsifiers to 10%
2% isoopropyl myristate with optiphen and vitamin E added after cool down
The only difference between the two is that the oil phase got very hot, perhaps 110*C on the emulsion losing viscosity… this is R&D so I rolled with it.
Could this heat denature the oil phase in some way. The one in question is certainly a lotion now and not a cream.
Thanks in advance
