**4. Conclusions**

Nanoemulsions are a relatively new class of dispersions which have gained popularity due to their high efficiency in delivery. There have been a lot of efforts and research to develop the preparation methods of nanoemulsions. This emerging component of nanotechnology has become an irreplaceable part and parcel of the cosmetic and pharmaceutical industries. Further research and development in this field can prove to be very crucial for these industries. Nanoemulsions have a huge potential to change the approaches to many fields as discussed in this chapter and

it can also play much more important roles in the future due to its uniqueness and increasing research in its field.
