Nanoemulsion in cosmetic: from laboratory to market

Abstract Over the last two decades, nanotechnology arena has given several potential carrier systems to the field of cosmetics and personal care products, which is the fastest growing industry in the world. Nanoemulsions (NEs) have gained significant popularity among various cosmetic formulators, as NEs showed immense potential in overcoming several drawbacks associated with conventional products. NEs bear momentous merits like enhanced and controlled skin penetrability, high stability, smaller droplet, and ease of formulation. This chapter attempts to uncover every aspect of NE applicability in cosmetics including challenges and downsides associated.
