= What are the positives and the negatives of the primary source? =
Two negatives make a positive in multiplication and division
Adding negatives? You get a negative. But if you multiply/divide 2 negatives, that's a positive.
yes !
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.
Biological washing powders are made by combining enzyme-containing ingredients, such as proteases or lipases, with other components like surfactants, builders, and optical brighteners. These enzymes help break down tough stains and organic material, making the detergent more effective in removing dirt and grime from clothing. The formulation is then mixed and processed into a powder form for packaging and distribution.
Biological detergents and washing powders use lipases and proteases to break down fat and protein molecules from food stains which have remained on clothing. The fatty acids, glycerol and amino acids which are produced are removed in the water during the washing process.
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.
Microorganisms like Penicillium fungi are grown in fermenters where they produce penicillin. The same process can be used to produce enzymes for biological washing powders. The organisms are grown in a controlled environment within the fermenter, allowing for large-scale production of these substances.
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.
Neither. Most washing powders are mixtures.
Biological washing powders contain enzymes that can break down proteins, such as those found in silk, causing damage to the fabric fibers. It is best to use a gentle, non-biological detergent specifically designed for delicate fabrics like silk to ensure the clothes are cleaned effectively without causing harm.

Enzymes used in biological washing powders are typically produced using genetically modified microorganisms like bacteria or fungi. These microorganisms are engineered to produce large quantities of the desired enzyme, which is then harvested, purified, and added to the washing powder formulation. The enzymes help break down stains and dirt on clothing by accelerating chemical reactions, making the washing process more effective.
non-bio
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.
