Solid vs liquid lipids emulsion stability
I make a simple moisturizer emulsion that has 5% lipids. The aim is to reduce the cost as much as possible. It is a low viscosity lotion in flip top bottle.
0.6% sodium stearoyl lactylate
2.4% glyceryl mono stearate
1% Shea butter or coconut oil4% petrolatum or mineral oil
1% phenoxyethanol/caprylyl Glycol
0.1% caprylyl Glycol
0.1% FO0.3% xanthan gum
0.2% dimethicone 5cst
My question is, does viscosity of lipid phase has any effect on emulsion stability?
I mean which one would be more stable? Petroleum+shea butter in oil phase or mineral oil+coconut oil.
