Submica M [INCI: Mica] from Sensient Technologies can be used to formulate very stable surfactant-free w/o emulsions containing up to 30% of aqueous phase dispersed in non-polar oils. Also based on mica, Submica E from the same company is added to the water phase to form an opaque cream-like gel with a good feel on the skin. Its particles are small platelets that have different polarities on the two big faces (negatively charged) and the four small faces (positively charged). In water these particles get organised due to electrostatic forces and build a house of cards structure that increases the viscosity of the aqueous phase. Droplets of oil can be trapped within the Submica E house of cards structure and it is possible to emulsify up to 20% oils.
