Laundry+Detergents+and+Enzymes+(Musung)

=**Introduction to enzymes and enzymes in laundry detergents**= Enzymes are protein that serves as a catalyst, a chemical agent which changes the rate of a chemical reaction more rapidly without having to use or change its own shape. We can find these enzymes commonly in our lives, while eating cheese or cleaning our laundry using laundry detergents. Laundry detergents are composed of enzymes that help clean laundries in our modern day lives; these special enzymes are called biological enzymes. Some of the most commonly used biological enzymes are: proteases, which digests protein stains; Amylase (a-amylase), which digests starch stains; and lipases, which digests fat or oil stains. Additionally, other enzymes used in some detergents are Guardzyme that inhibits dye transfer and Carezyme that remove the fuzz that builds up on cotton clothes.

=Types of biological enzymes in laundary detergents [|pic]=

Proteases
Proteases break down proteins, meaning Proteases work effectively on blood, egg, gravy, and other protein stains. 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 e 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 laundry detergents, which solubilizes starch-containing stains like baby food, spaghetti, mashed potatoes, oatmeal, gravy, chocolate, tomato sauce and other starch contained foods. 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 from garments. 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 lipstick, salad oil, animal fat and butter from clothes after washing the garments several times with liquid and powder Lipase containing laundry detergents.

**Cellulose**
Cellulose is helps remove strain, brightens the color, and softens cotton and cotton-containing textures. One example of a detergent enzyme, SEBrite-COLOR, removes cotton cellulose microfibrils on damaged cotton garments damaged while being washed. When washing the cotton-containing garments repeatedly with a laundry detergent containing Cellulose it will improve also remove soil Furthermore, by using cellulose, it brightens fabric color, and softens and restores original garment appearance.

**Other Laundry detergent enzymes**
Guardzyme, used to inhibit dye transfer Carezyme, used to remove the fuzz that builds up on cotton clothes

=How these enzymes work=

There need no special chemical reactions to occur prior to these biological enzymes to work. These enzymes have their own specific work and can perform their jobs by them selves; for isntance, when proteases is added to the laundary detergent and washed several times the garments with proteins strain on will disappear. These enzymes basically works by themselves. In order for these enzymes to work well it needs an optimal temerature of (30~) 40 degrees water to perform well, however, there are now new products coming out where it can be used in low temperature water and more neutral pH.

=Advantages and Disadvantages=

Advatantages of using biological laundry detergents
Biological laundry detergents can clean off many types of stains from your garment Not just cleaning the garment, biological laundry (cellulose) also allows garments to soften and recover to original garments appearance The mixture of these biological detergents performs more better than normal laundry detergents

Disadvantages of using biological laundry detergents
For biological enzymes to work effectively it requires warm tempertaure water (40 degrees). Fortunately there have been inventions made where these biological enzymes could work under low water temperature and more neutral pH.
