Question

What are micelles?

Answer 1

Micelles are aggregated particles formed by surface active agents like soaps at concentrations above the critical micellization concentration (CMC). They consist of hydrophobic hydrocarbon chains clustered inside and hydrophilic charged groups arranged on the surface, forming negatively charged colloidal particles in water. Micelles help emulsify oily dirt by encapsulating it inside, aiding in cleaning action. Each micelle may contain around 100 molecules or more.
