Chemistry:
Dirt that is not easily brushed off or removed with water alone actually has some form of fat or grease in it. Since oil and water repel each other, water alone can't surround and remove oil.Soap has hydrophilic(water loving) molecules that are attracted to water on one end and lipophilic(oil loving) molecules attracted to oil on the other end.
Function:
The soap molecule surrounds the grease and the lipophilic ends attaches to the fats and oils. The hydrophilic ends are attracted to water, this allows the soap to trap the dirt and wash it down the drain with the water.
Types:
Different soaps are made for different purposes. Beauty and bath soaps have ingredients in them that are gentle on the skin. Laundry detergent is made specifically to clean clothes. Some soaps are made to have low suds, such as those used in high-efficiency or HE washing machines.
