**5. Future scope**

The market for nanoemulsions is expected to grow at the rate of 8.8% between the years 2018 and 2023 [47].The growth is expected to be driven by the increasing demand for the treatment of chronic diseases and vaccine development. Nanoemulsions have huge potential to improve the efficacy of cancer immunotherapy by multiple folds. The major hindrance to the growth is the expensive manufacturing methods and scaling up with cost effectiveness. The technological innovation and scaling opportunities is expected to decrease the cost of production. Due to its unique properties, nanoemulsions can also become an active component in the chemical, agricultural and engineering fields. Nanoemulsions can also find an application as drug delivery platforms to noval phytopharmaceuticals given the new interest in herbal drug formulations in the world [32].
