Soaps and detergents are always seen as metallic esters due to their possession of both hydrophobic and hydrophilic areas. The hydrophobic side makes your soap to be soluble in water while the hydrophilic side, being the hydrocarbon side is always oily (your fatty acid), it makes it possible for your soap to terminate their incidences of backward reaction. ie. The hydrophobic side does not allow the already washed dirt to re-deposit itself again on the material washed which may be your clothe.
This is what makes detergent production and soap production almost the same process.
As i said earlier, the process of producing soap is similar that of detergent with exception of few differences in the compositions. But, people were once asked in my school during their I.T. defence, the difference between soap and detergent. This, some people said that soap is solid while detergent is powdery. For me, as a , I saw that the difference is just that soaps are biodegradable while detergents are synthetic, not in the area of state. We have liquid soaps which the procedure of production can be made available on demand. Please, permit me to use chemical terms a bit.
Further definition:
Soap:
Soap is a metallic ester that contains 13 to 18- molecules of Carbon and about 35-molecules of Hydrogen.
Biodegradable:
This is a chemical way of saying that a something is made from natural products.
Metallic ester:
From our physical sciences, we know that a metal is something that has the ability to react. Esters are ………………………. (test your brain here)
Soaps are metallic esters due to their possession of hydrophobic ( Oily or insoluble in water, ie. hydrocarbon chain) and the hydrophilic (water loving or soluble in water, i.e. COO- Na+)
During this process a slow chemical splitting of the neutral fat takes place; the fatty acids then react with the alkali carbonates of the plant ash to form soap (this reaction is called saponification).
