Question

Quizplus · Accepted Answer

Soap molecules assemble into micelles indeed, but grease molecules do not absorb onto the surface of micelles. Instead, the grease or oil gets entrapped in the center of the micelle, with the hydrophobic tails of the soap molecules interacting with the grease and the hydrophilic heads facing outward, allowing the grease to be washed away with water.
