why does the skin of your fingers shrink when you wash clothes for a long time
Answers
ANSWER -
Soap solution is a hypertonic solution i.e., more concentrate than our skin cells. As we know, when the cell is immersed in a hypertonic solution, water diffuse out of the cells by osmosis (diffusion of water across semi permeable membrane), due to lower concentration of water outside the ceil. As a result, the cell shrinks. The process is called exosmosis. During washing of clothes, exosmosis takes place in the skin cells. This leads to shrinkage of skin over the fingers while washing clothes for a long time.

Answer:
Clothes are washed with soap or detergent solution. The solution is hypertonic as compared to osmotic concentration of our skin cells. The washing solution, therefore, results in exosmosis in the skin cells that come in contact with it for some time. Due to this reason, the skin over the fingers shrinks while washing clothes for a long time.
