Preparation and Evaluation of Physical Characteristics of Vitamin E Nanoemulsion using virgin coconut Oil (VCO) and olive oil as oil phase with variation Concentration of tween 80 Surfactant

Vitamin E (alpha-tocopherol) has an anti-aging role and can protect the biologic membrane damage from free radicals. Vitamin E is highly lipophilic and has low stability, therefore to improve its effectiveness it is necessary to select appropriate carriers. Nanoemulsion is a drug delivery system in the form of aqueous oil dispersion stabilized by a combination of surfactants and co-surfactants that having droplet size 20–600 nm.
