Why conventional emulsions appars milky white but microemulsion appear as transparent?

Conventional emulsions appear milky white due to the large size of their dispersed droplets, which scatter light effectively. In contrast, microemulsions consist of much smaller droplets, typically in the nanometer range, allowing light to pass through with minimal scattering, resulting in a transparent appearance. Additionally, the surfactants used in microemulsions stabilize the system and reduce droplet size, contributing to their clarity.
