What is a micelle in chemistry?

Similarly, it is asked, what is a micelle and how is it formed?

Micelles are lipid molecules that arrange themselves in a spherical form in aqueous solutions. Micelles contain polar head groups that usually form the outside as the surface of micelles. They face to the water because they are polar. The hydrophobic tails are inside and away from the water since they are nonpolar.

How does micellar cleansing water work?

Atomic Imagery via Getty Images Micellar water is made up of micelles (tiny balls of cleansing oil molecules) suspended in soft water. “The idea is that micelles are attracted to dirt and oil, so they are able to draw out impurities without drying out the skin,” she says.

What makes soap work?
