À propos de cet audio
Soap is the result of the chemical reaction between an alkali (sodium or potassium hydroxide) and a fatty acid such as olive oil, coconut oil, etc. This reaction is called saponification. This combination is soluble in water and due to its detersive properties, it is used to wash and disinfect. Depending on the use for which it is intended, other additives of natural origin such as dyes, aromas, essential oils, herbs, etc. can be added.
On the other hand, the detergent is a mixture of various synthetic substances, many of them derived from petroleum, which have the chemical property of dissolving dirt.
