Galenic Aspects of the Excipient?
The aqueous external phase emulsion (o/w) forms by emulsifying a waxy-type fatty agent such as glyceryl monostearate in the water thanks to Tween 80 (Polysorbate 80), a non-ionic surfactant. Therefore, the emulsion formed is non-ionic. It has a high evanescence (barely leaves a greasy residue after application), a fundamental aspect given the application area. Accepts without stability problems the number of essential oils added.
Propylene glycol increases the extensibility of the emulsion favoring its application.
Vitamin E is a natural antioxidant that prevents the oxidation of essential oils over time.
