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

Why do some washing powders contain enzymes?

Enzymes in washing powders help break down stains and dirt by accelerating chemical reactions. This can make the washing process more effective at lower temperatures, reducing the need for hot water and harsh chemicals, and making the detergent more environmentally friendly.


How do enzymes in washing powders remove protein stains from clothes?

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.


What is washing powder used in?

Protease enzymes


How the enzymes may increase the efficiency of the washing powder in removing stains form clothes?

Enzymes in washing powders help break down complex molecules in stains, like proteins or lipids, into smaller, soluble molecules that can be easily washed away. This increases the efficiency of the detergent by accelerating the stain removal process. Enzymes also work effectively at lower temperatures, reducing energy consumption during laundry.


Why should you not use hot water in washing powders?

Hot water can cause some washing powders to clump or solidify, making them less effective at cleaning clothes. Additionally, hot water can also break down the active ingredients in the washing powder, reducing its cleaning power. It's generally best to use warm or cold water with washing powders to ensure they work properly.

How do non bio washing powders work?

Non-bio washing powders work by using milder cleaning agents and enzymes to break down stains and dirt on clothes. They are designed for people with sensitive skin or allergies to the enzymes used in bio washing powders. Non-bio washing powders are effective at cleaning clothes without causing irritation to the skin.


what types of washing powders contain enzymes?

non-bio


What are the types of enzymes likely to be used in washing powders?

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.


The use of micrognism and fermenters to manufacture the antibiotic penicilin and enzymes for use in biological washing powders?

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.


Describe how enzymes used in biological washing powders are produced?

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.


Why do washing powders have enzymes with a low temperature?

Enzymes in washing powders that work at low temperatures help to break down stains and dirt effectively without requiring high heat. This is beneficial for energy efficiency and can prevent damage to delicate fabrics that may not be able to withstand high temperature washing. Additionally, using enzymes at lower temperatures can help reduce shrinking and fading of colored clothing.

Are the enzymes in washing powders digestive enzymes?

The enzymes in washing powders are not digestive enzymes. They are typically proteases, amylases, and lipases that break down protein, starch, and fats found in dirt and stains on clothing. These enzymes help to remove stains more effectively by breaking them down into smaller molecules that are easier to wash away.


Why are biological washing powers good at removing stains?

Biological washing powders contain enzymes that break down organic stains like food and sweat. These enzymes help to loosen and remove the stains effectively during washing, making the detergent more efficient at stain removal.


What is the advantage of using bioligical washing powder?

Biological washing powders contain enzymes that help break down tough stains and dirt, making them more effective at removing grime from clothing. These enzymes work at lower temperatures, saving energy and reducing the need for hot water.
