How Does Soap Work
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.
Soaps work because of the structure of water. Water molecules contain 2 hydrogen atoms and an oxygen atom trapped between them. This makes the water molecule polar with a positive charge at one end and a negative at the other.
Ad an ionic compound like sodium chloride and the positive and negative parts of water are attracted to the positive ions and negative ions. This is what makes soap water soluble. The solubility of the soap depends on the strength of the attraction.
In this way, the fat in our skin, and on our skin are water soluble, making it easy for them to wash away. The epidermis needs a non-polar material that can be dissolved, moved, and then restored to its non-polar state, like a lipid, or triglyceride.
A lipid is made from two parts fatty acid, and an alcohol called glycerine. Both the fat and glycerine are water soluble.
Saturated fats are solid at room temperature, like l lard and butter. Unsaturated fats are liquids at room temperature like safflower oil. While the unsaturated fat is healthier, liquid soap is not easy to handle.
Cleansing and astringent herbs may be added to the mix, to improve the scent and cleansing ability of the soap. When the soap dissolves, dirt and pollutants are trapped, and sloughed away with the water.
As the soap takes away pollutants, dead skin, biological contaminants, and waste, the skin works less to remove toxins from the body. Drinking lots of water improves this task, and keeps the skin healthier.
This could be one reason why we are seeing woman in their 50s who look young. They have 'good' soaps, and a good diet that keeps their epidermis working well. Like all 'organs' a healthy epidermis looks healthy - and a chemically damaged and abused organ looks wasted, damaged, and color spotted.
