Because normal washing powder cannot break down some stains.
For example, an oil stain on a shirt would not go away in the wash.
However, an enzyme called lipase could be added to the washing powder (lipase breaks fat down) and this would break the oil stain down to solube products which would then wash away.
A protein stain would require the use of the enzyme protease which breaks it down to amino acids (a soluble product).
etc.
Using a biological washing powder is also more eco-friendly because it is bio-degradable and because the wash would be at a lower temperature (about 37C) so as not to denature the enzymes (their 3D shape would change and they would no longer be able to work). This saves energy.
However babies' clothes should be washed in non-bio washing powder so that the wash can be at a higher temperature and therefore kill bacteria.
Hope this helps, I'm currently revising for my Biology GCSE. X
enzymes break things down so im guessing to help break dirt an things down ---- Different enzymes are used to digest different types of stains. For instance, lipases get rid of oily stains, cellulase to break down grass stains, and other enzymes to clear blood fro mclothes.
The main advantage of using enzymes in washing powders is environmental. Enzymes work at lower temperatures compared to synthetic substances (40oC compared to 60oC), so less energy is required to heat the water, so fewer carbon dioxide emissions result. enzymes have things called proteases in them which break down proteins
Enzymes are proteins that speed up chemical reactions. They work in washing powders by two substrates binding to a specific molecule in this case a stain The binding takes place at the acctive site. When the substrate has finished binding a enzyme substrate complex is formed. The enzyme tenses then weakens the bonds in the substrate because of this the two substrates bind together to make a different molecule. It is that released leaving the enzyme to reform it's natural shape. Enzymes are proteins that speed up chemical reactions.

Certain foods or substances stain clothes very badly. Blood, egg and milk all contain lots of protein. Enzymes are added to modern biological washing powders because they digest these proteins in the substances, removing the stains. They produce less pollution compared to detergents.
the uses of enzymes in washing powders are to get rid of the stains on the cloth
It digests food that get stained in our clothes and thus makes the washing machine process more effective.
To break larger molecules into smaller pieces I'd imagine.
because to improve the quailty in your clothes and decrase the surface tension.
Protease enzymes
If you magnify or look very closely to the shape of the threads that make up the cloth, they are organized like a series of tiny squares. Stains, such as protein stains, get stuck in these tiny squares. Protein is a large insoluble molecule. An enzyme, such as protease, in the washing powder breaks down this protein into smaller more soluble molecules. The new molecule is soluble, thus when the water in the washing machine rises, or you rinse the piece of cloth, the water dissolves this molecule and carries it away from the cloth. This leaves the square spaces between the threads clean and empty of stains. This means that washing powders with enzymes can efficiently remove protein stains such as blood.
Ajax is a washing powder that has been proven to clean the best. Taking away scum is what Ajax does best, when it comes to dirtiness that needs to be removed.
Batteries, any dairy product. Help by researching!!

The protease enzyme is used in some washing powders. The protease enzyme usually comes from bacteria like Bacillus licheniformis or Bacillus subtilis and can be produced in fermenters which hold many litres of culture medium and bacteria.

Yes. These enzymes degrade or break up large molecules such as fats, producing simpler substances that tend to be easier to dissolve in water (and thus, wash away).
Penicillium from fungi is mixed with sugar in a fermenter. Fungi grows for about 15-24 hours and then begins to secrete penicillin. The solution is filtered off and is concentrated to give penicillin. Enzymes lipase in biological washing powders are used to break down fats or grease on clothes and protease used to break down proteins such as blood stains.
It contains a range of enzymes (globular proteins). These powders are typical more suitable for lower temperature washes, as high temperatures denature enzymes.
Well... BASICALLY... they aren't even in washing powder, washing powder consists of tiny women, with really small sponges, who clean, and then cover your clothes in not very nice smelling odurs. I hope this helped. Love 11YD1 Science.
Some people can have allergic reactions to biological washing powders due to the enzymes in them. One of which is protease, hope this helps?
Protease enzymes
Protease enzymes
Because some laundry powders contain enzymes that are proteolytic or hydrolytic and would denature and lose their function at that high of temperature. ( 60o C = 140o Fahrenheit )
