Is there a difference in the decontamination ability of enzyme laundry detergent and ordinary laundr

The enzyme mentioned in the laundry detergent should refer to a certain protease, and some stains such as: blood, urine, milk ......The main components are also proteins, and proteases can play a catalytic role in decomposing some smudges, which plays a role in decontamination. I guess the main intention of this question is to let you understand that proteases can break down proteins, that is, a certain enzyme can break down specific substances!

Dirt on clothes contains proteins, and proteases hydrolyze proteins into amino acids. You must know that proteins are not easily soluble in water (please refer to the experiment of extracting proteins from high school textbooks), and amino acids contain -cooh, so they have a certain hydrophilic ability. In general, proteases hydrolyze proteins that are not easily soluble in water into amino acids that dissolve in water, so proteases can decontaminate.

1. Material preparation: take a large piece of white cloth and evenly pollute it with oil. The cloth is then randomly cut into small pieces.

2. Experimental process: randomly take a number of small pieces of contaminated cloth, and wash them with enzyme laundry detergent and ordinary laundry detergent in the same way. After washing, dry separately in the same way.

3. Identification: Compare the cloth washed by two different washing powders, observe the removal of oil stains, and make a record. The results are analysed to see if there is a difference in the stain removal capacity of the two detergents.

1) Is there any difference in the decontamination ability of enzyme laundry detergent and ordinary laundry detergent? Let's do it together.

The question you asked: Does enzyme laundry detergent have a stronger stain removal ability than regular laundry detergent?

The assumption you made: Enzyme laundry detergent has a stronger stain removal ability than regular laundry detergent.

Your ** plan: Wash two dirty rags with two kinds of laundry detergent respectively, and see who washes it cleaner in the same amount of time.

Materials and utensils: ordinary laundry detergent, enzyme laundry detergent, rags for wiping grease stains, etc.

2. Take another basin of warm water with the same amount, put the same amount of ordinary laundry detergent, and put in a rag of the same size and dirty;

3. After a period of time, take out two rags and rinse them. Compare cleanliness.

Your Expected Results and Conclusions:

Expected Results: Cleaner cloths washed with enzyme laundry detergent.

Conclusion: Enzyme laundry detergent has stronger stain removal ability than ordinary laundry detergent.

Ask the question: Does enzyme laundry detergent have a better stain removal ability than regular laundry detergent?

Make a hypothesis: enzymatic laundry detergent has a better stain removal ability than ordinary laundry detergent.

**Scheme. Materials and utensils: ordinary laundry detergent, enzyme laundry detergent, rags for wiping grease stains, etc.

Method steps: Clean the rags with ordinary laundry detergent and enzyme laundry detergent respectively.

Expected results and conclusions: Enzyme laundry detergent has stronger stain removal ability than ordinary laundry detergent.

The main purpose of adding enzymes is to break down substances into small molecules, and the human body relies on enzymes to digest and absorb them, which should be cleaner.

The constant factor should be the temperature

Enzyme laundry detergent has strong stain removal ability.

Ha, brother's homework hasn't been finished yet.

What is the washing effect of enzyme washing coarse powder? Let's find out.

Washing effect with enzyme laundry detergent

Theoretically, laundry detergents containing enzymes have a better cleaning effect. However, since enzymes are a biocatalyst, the washing effect is no different from that of regular laundry detergent if used incorrectly.

The enzyme activity in the enzymatic laundry detergent is an important indicator of the decontamination effect, because the enzyme activity represents the content and catalytic capacity of the effective enzyme preparation. In the national standard GB13171-91, the enzymatic activity of the air raiding detergent with enzymes should be 650 g.

The pH value of enzyme laundry detergent is generally not more than 10, and the water temperature can give full play to the washing effect when it is 45 60. When the water temperature is higher than 60, the alkaline protease will lose its activity. When the water temperature is lower than 15, the enzyme activity decreases rapidly, which affects the washing effect.

When the temperature is below 40, the enzyme acts more slowly, but it is not easily destroyed and inactivated. Therefore, the optimal temperature for alkaline protease detergent is 40 to 50. If the clothes are not washed at the correct temperature, the effect is not significant.

Expand: What is the difference between regular laundry detergent and enzyme laundry detergent

Enzyme laundry detergent has enzyme preparations, while ordinary laundry detergents do not have enzymes, and this is the biggest difference between them. At present, there are four types of enzyme preparations used in enzyme laundry detergent: protease, lipase, amylase, and cellulase. They have a special ability to remove dirt and take up less cost in laundry detergent formulations, while the washing effect is greatly improved.

Expansion: The harm of laundry detergent to the human body

1. Damage**.

Laundry detergent contains compounds that can make your hands feel dry after washing your clothes.

2. Allergic reactions.

The compounds of laundry detergent that enter the body may cause allergic reactions.

3. Damage to the blood system.

Compounds are easy to pollute human blood, although human blood has a certain detoxification function, but a large number of compounds into the blood will inevitably cause blood lesions.

4. Nervous system damage.

Some laundry detergents containing synthetic aromatic substances can cause poison to the human nervous system, causing nausea and vomiting and other symptoms.

5. Damage to immune function.

Some laundry detergents are added with fluorescent agents and brighteners, which are not easy to decompose, which are difficult to decompose after entering the human body, and the accumulation in the human body will greatly reduce the body's immune function.

6. Damage to the reproductive system.

Many laundry detergents contain chloride, and excessive chloride can seriously damage the female reproductive system.

That's all for today's sharing, I hope it can help you.

The difference between ordinary laundry detergent and enzyme laundry detergent lies in the strength and weakness of the decontamination ability. Enzyme laundry detergent can remove stains from clothes with more hands. Enzymes can break down dirt.

Enzyme laundry detergent can wash heavily stained shirts, sheets, radical sheets and other large pieces of clothing, can remove blood stains, soy sauce, urine stains, gravy, milk, sweat stains and other dirt, silk fabrics can not use enzyme laundry detergent, otherwise the enzymes in the laundry detergent will destroy the silk fiber.

Enzyme laundry detergent can clean clothes with blood stains, soy sauce, urine stains, gravy, milk, sweat stains and other clothes that are difficult to wash off, and will not hurt the clothes, it is best to use about 40 warm water during the washing process, and soak the clothes for 30 minutes.

Enzyme laundry detergent adds alkaline protease microorganisms to the formula, which can effectively remove dirt that is difficult to clean, but the water temperature used cannot exceed 50, otherwise the enzymes in the laundry detergent will be killed and will not play a role in decontamination.

Enzyme laundry detergent can not be stored for a long time, need to be used within the specified date, if the storage time is too long, the activity of the enzyme will disappear, enzyme laundry detergent is suitable for cleaning shirts, sheets and bed sheets and other large items, not suitable for washing silk wool fabrics, otherwise it will destroy the silk dust lead hair fiber.
