What is difference between nanoemulsion and microemulsion?

Answer 1

Microemulsions (ME) are thermodynamically stable while Nanoemulsion (NE) is kinetically stable.

ME have less globule size than NE.

ME have long term stability while NE have short term stability.

Answer 2

Nanoemulsions have droplet sizes in the nanometer range, typically less than 100 nm, while microemulsions have droplet sizes in the micrometer range, typically between 100 nm to 1 μm. Nanoemulsions have a higher surface area and stability due to smaller droplet size, making them ideal for encapsulating and delivering active ingredients. Microemulsions have larger droplet sizes, making them suitable for solubilizing larger amounts of hydrophobic compounds.
