Advantages And Disadvantages Of Detergents

Solvents and detergents are important in a number of industries and most are derived from petroleum. There is increasing concern that prolonged contact with solvents causes health problems – for workers in the factories where solvents and detergents are produced, and for those using such substances in their everyday work. There are two additional drawbacks to these solvents and detergents: one day the crude oil from which they are derived will no longer be available; and they present a major waste disposal problem as they do not break down readily when disposed off. So bio detergents are in use nowadays to solve these problems. Biodetergents (Also called Biodispersants or Biopenetrants or Organic Dispersants) Chemicals that can penetrate…show more content…
It was the German scientist Otto Rohm who first patented the use of pancreatic enzymes in 1913. The enzymes were extracted from the pancreases of slaughtered animals and included proteases (trypsin and chymotrypsin), carboxypeptidases, alpha-amylases, lactases, sucrases, maltases, and lipases. Thus, with the exception of cellulases, the foundation was already laid in 1913 for the commercial use of enzymes in detergents. Today, enzymes are continuously growing in importance for detergent formulators. The most widely used detergent enzymes are hydrolases, which remove soils formed from proteins, lipids, and polysaccharides. Cellulase is a type of hydrolase that provides fabric care through selective reactions not previously possible when washing clothes. Looking to the future, research is currently being carried out into the possibility of extending the types of enzymes used in detergents. Each of the major classes of detergent enzymes – proteases, lipases, amylases, mannanases, and cellulases provide specific benefits for laundering and proteases and amylases for automatic dishwashing. Historically, proteases were the first to be used extensively in laundering. Today, they have been joined by lipases, amylases and mannanases in increasing the effectiveness of detergents, especially for household laundering at lower temperatures and, in industrial cleaning…show more content…
It also removes protein-containing stains such as milk, Soya, blood, grass and body fluids of human. Dried protein-containing stains tend to strongly adhere to textile fibers binding other soils including inorganic materials, dirt and colored substances. In general Proteases breakdown protein stains into peptides or amino acids, which can be rinsed away more easily. Amylases Amylases break down starches. An example of an Amylases enzyme; the detergent alpha-amylases are founded usually in liquid and powder form of detergents, which solubilizes starch-containing stains. Addition of our alpha-amylases to laundry detergents and laundry pre-spotters, enhances removal of starch-containing stain residues, increases fabric whiteness, and reduces re-deposition of starch-containing stains on co-washed garments and fabrics. Lipases Lipases help remove fatty food stains. Lipases containing laundry detergents in now a day are capable of using it at a lower washing temperature and more neutral ph. Lipases in general cleans problematic stains such as animal fat and butter from clothes after washing the garments several times with liquid and powder Lipase containing
