Properties of Surfactants for detergents

ammonium | 20 March, 2018 14:23

A detergent is an effective cleaning product because it contains one or more surfactants. Because of their chemical makeup, the surfactants used in detergents can be engineered to perform well under a variety of conditions. Such surfactants are less sensitive than soap to the hardness minerals in water and most will not form a film.Detergent surfactants were developed in response to a shortage of animal and vegetable fats and oils during World War I and World War II. In addition, a substance that was resistant to hard water was needed to make cleaning more effective. At that time, petroleum was found to be a plentiful source for the manufacture of these surfactants. Today, Surfactants for detergents are made from a variety of petrochemicals (derived from petroleum) and/or oleochemicals (derived from fats and oils). Surfactants are a large group of surface active substances with a great number of (cleaning) applications. Most surfactants have degreasing or wash active abilities. They reduce the surface tension of the water so it can wet the fibres and surfaces, they loosen and encapsulate the dirt and in that way ensure that the soiling will not re-deposit on the surfaces.Surfactants have a hydrophobic (water repellent) part and a hydrophilic (‘water loving’) part. The hydrophobic part consists of an uncharged carbohydrate group that can be straight, branched, cyclic or aromatic. Detergents and soaps are surfactants , short for surface-active agent . Surfactants have a hydrophilic side of the molecule attaches to water, and a hydrophobic side of the molecule that avoids water. In the absence of oils, the hydrophobic side sticks out of the surface of the water drop. There is no longer any water at the surface to form a strong surface tension, so the water no longer beads up, but spreads. The hydrophobic end of the molecule is also free to attach to grease, fat, or oil on the surface, aiding in the spreading.
