Science C Period (How does Soap Work) By Carly Savarino ...- describe the cleansing action of soap ,The cleansing action of soap is determined by its polar and non-polar structures and how solubility works.Explain the mechanism of the cleaning action of soaps ...Dec 16, 2013·Q.15 Explain the mechanism of the cleaning action of soaps. Answer:-Cleansing action of soaps: The dirt present on clothes is organic in nature and insoluble in water. Therefore, it cannot be removed by only washing with water. When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the cloth.

How Soap Works - ThoughtCo

Jul 19, 2019·How Soap Cleans . Soap is an excellent cleanser because of its ability to act as an emulsifying agent. An emulsifier is capable of dispersing one liquid into another immiscible liquid. This means that while oil (which attracts dirt) doesn't naturally mix with water, soap can suspend oil/dirt in such a way that it can be removed.
