Water on top of Oil
Recently I’m working on a triphase product using silicone, aqueous and oil.
However, I noticed that there is water layer (orange) on top of the oil phase (yellow). I tried it with 3 types of oil which are Coco Caprylate/Caprate (density 0.859 g/cm3) , Decyl Oleate (density: 0.864 g/cm3) and Oleyl Erucate (density: 0.868 g/cm3) , all having the same issue. The water I’m using is reverse osmosis water without other additives at this stage. I also tried to add in some salt to increase the cohesion force between water but it doesn’t work.
May I know why is it so? Is it the oil phase, the water phase or the dye (Yellow 6 and Yellow 11) having issue?
Appreciate your advice in advance.
Thank you very much.
