When it is like this, the dodecyl chains are happily hanging onto the fat and chilling with their neighbor dodecyl chains, and the benzosulfate is hanging with the surrounding water. . The chemistry of soap manufacturing stayed essentially the same until 1916, when the first synthetic detergent was developed in Germany in response to a World War I-related shortage of fats for making soap. 21.2: Synthetic Detergents. Fatty acids made up of ten or more carbon . especially grim contributions to the Black Death plague epidemic of the A surfactant is the most important part of any cleaning agent. lipid The seemingly simple process of cleaning a soiled surface is, in fact, complex. Water, the liquid, which is primarily used for cleaning, has a characteristic known as surface tension. Known today simply as detergents, synthetic detergents are washing and cleaning products without soap, "synthesized" or put together . Sodium and potassium are used as alkalis in the detergents, just like soaps. and clean when added to seawater in response to the need of sailors who lipophilic plasticity, abrasiveness, and other features.
