When you do laundry what cause the nonpolar oil or greasy dirt to mix with the polar water?

Most laundry dirt is oily or greasy. Detergents can mix with both oil and water, so when the wash water goes down the drain, the soap and dirt go with it.
Detergent molecules are designed with a polar head of the molecule and a non-polar tail. The detergent molecule thus "ties together" the water and the grease. Soap performs the same function.

How does laundry detergent work on a molecular level?
The molecule that makes up soap or detergent has a polar head and a nonpolar tail. In chemistry, compounds that are polar like to mix with other polar compounds and compounds that are nonpolar like to mix with other nonpolar compounds. This is why oil and water don't mix. Water is polar and oil is nonpolar. Oil and grease are a nonpolar compounds. When in water the soap molecules will arrange themselves in such a way that the nonpolar tails surround the grease creating a spherical droplet. On the face of this sphere is the polar heads of the soap molecule. This allows it to interact with the polar water. This is how soap and laundry detergent are able to remove oil and grease and wash it down the drain.
