- detergents contain a hydrophilic which is soluble in water.
- they also contain an hydrophobic group, which is their long chain which is hydrophobic and soluble in organic materials.
- so when you have to clean organic materials the hydrophobic part catches the waste and hydrophilic ensures that water can put it away.
Cleansing Action of detergents:
- dirty blouse
- soap or detergents dissolve in water and reduces the surface tension of water.
- water wets the dirty blouse.
- the hydrophobic part of the anion dissolve in grease. the hydrophilic part dissolve in water.
- grease is loosened and lifted of the surface. heat, rubbing, and scrubbing can help this process.
- the polar ends of anions surround the grease. the grease is lifted of the surface and suspended in water.
- the grease is dispearsed into smaller drops. heating, rubbing and scrubbing can help this process.
- rising away the dirty water removes the grease droplets.
- clean blouse.
