How Soap Clean ?

                           Substance which can be dissolved in water and others that cannot. For example water and oil. water and oil do not mix together. So we try to clean oil stain from a cloth or hand water is not enough. So we need a soap.
                           Soap is formed by a molecules of hydrophilic and hydrophobic. So that soap molecules act like a diplomat, and improving the relation ship between water and oil.

How?
                    When soap is added to the water

• The hydrophilic heads of molecules stay into the water.
• The long hydrophobic chain join the oil.

                      Then they formed circular groups named micelles, with the oil material absorbed inside and trapped. An emulsion of oil in water is then formed after that the oil particles becomes suspended and dispersed into the water. Soap cleans by acting as an emulsifier. It allows oil and water to mix. So that oily grime can be removed during rinsing.
