Why are soaps good at removing grease?
Quick Answer
Soap molecules have one end that likes water and one end that likes fat. That lets them surround grease and lift it away in tiny droplets.
The Full Story
Soap is made of surfactant molecules with a hydrophilic head and a hydrophobic tail. The tail embeds itself in oils and grease, while the head stays attracted to water. This allows soap to form micelles, tiny spheres that trap oily dirt and rinse it away. The same chemistry is why soap can also help break up surface tension and spread water over dirty surfaces.
Key Facts
1.Soap molecules are amphiphilic
2.They form micelles in water
3.Water alone does not dissolve grease well
