it has two parts long chain is hydrophobic..............water hating it attach with the oil
and hydrophilic...............waterloving it get attached with the water
when we wash the clothes they soaps increase the surface tension and take the dirt awayDescribe the cleansing action of soap?
Soap helps remove dead skin. Believe it or not, the skin is the body's largest organ, responsible for removing toxins and waste from the body.
Soap is made to remove the dead skin from the top layer of skin - the epidermis - and the microbes that eat them. Soap should be used with a brush to help perform this task.
A toner will close the pores and prevent them from being clogged with dead skin and pollutants in the air.
A good soap will do both. The soap does not need to lather to do this. There are different types of soap. A good soap is made from oils and fatty acid. The oils are mixed with alkali to form glycerin and the salt of the fatty acid.
The surfactants (surface-active agents) in soaps remove grease and dirt because Surfactants have a molecular structure that acts as a link between water and the dirt particles. So the soap actually works like a magnet, or glue, that picks up the dirt and adheres it to the water which then drains away.
A good soap may contain a toner or astringent to tighten the pores, but adding moisturizers, perfume, colors, and scents may actually work against the process by being deposited on the skin and clogging the newly cleaned pores.
