Will enzymes be environmentally friendly?

Enzymes can be completely biodegradable in the natural environment, which is a new kind of raw material which is taken from the natural benefit to mankind. Moreover, enzymes can replace chemicals in many applications, reducing environmental damage. In addition, enzymes make various reactions under mild conditions, do not require harsh conditions such as high temperature, high pressure, reduce the use of energy, but also reduce greenhouse gases such as carbon dioxide emissions in the air. Therefore, the use of enzymes, can better protect the environment we rely on to survive.


What should be paid attention to when using enzyme detergent?

Enzyme is a kind of heat sensitive material, temperature is an important factor that affects enzyme activity. Therefore, the washing water temperature should be controlled in about 40 ℃, not to use more than 60 ℃ of blister washing powder, so as to avoid the enzyme agent loss of activity, thereby losing decontamination role.

Add enzyme detergent can not be used to wash silk, wool-containing protein fiber fabrics, because enzymes can destroy protein fiber structure, affecting the silk, wool fabric fastness and luster.


What is phosphorus detergent? What is phosphorus-free detergent?

Phosphorus detergent is a kind of products with phosphate as the main additive. Phosphate not only softens the water quality, but also has many excellent properties, such as alkaline buffer, suspended stain and anti-sedimentation.

Other chemicals are used in the technical formulations of phosphorus-free detergent to replace these functions of phosphate. At present, the use of 4A zeolite with the appropriate macromolecule compound or the use of layered silicate to replace phosphate.


Why to produce and use phosphorus-free detergent?

Phosphorus is a kind of nutrients, once into the water excess, will cause algae planktonic microorganisms, the water dissolved oxygen reduced, kill fish and other organisms. In anaerobic conditions, the rapid multiplication of anaerobic bacteria, may produce toxins and unpleasant sulfur compounds, the water quality deterioration, this phenomenon is called "eutrophication."

Phosphorus entering rivers and lakes is mainly derived from human excrement, drainage of farmland and phosphate in washing products.

Due to the large investment in sewage treatment facilities, there is no condition for the comprehensive treatment of sewage, the government authorities believe that in this case, the lake eutrophication in the more serious areas of economic development in the implementation of detergent in the prohibition of phosphorus. In order to meet the needs of the phosphorus-free areas, the production and use of phosphate detergent.


is phosphorus-free detergent worse than phosphorus-washing detergent?

Currently, countries are actively studying the replacement of sodium tripolyphosphate used in detergent. At this stage, mostly through the 4A zeolite instead of sodium tripolyphosphate and improve the formula to optimize the formula of phosphorus-free detergent, now the market on the sale of phosphorus-free washing powder detergent is basically the same decontamination capacity. As long as the brand to buy a good quality phosphorus-free detergent, you can achieve the effect of washing, but also to protect the environment.


Why soak time is longer than phosphorus powder with phosphorus-free detergent?

The exchange rate of 4 a zeolite and calcium-magnesium ion in phosphorus-free washing powder is slower than that of sodium tripolyphosphate chelate calcium-magnesium ions, that is, phosphorus-free detergent softening water speed slow, and 4 a zeolite insoluble in water, by its configuration of washing powder dissolved slowly, therefore, the use of phosphorus-free washing powder when the appropriate more soak a few minutes is beneficial, but not too long.

What is the role of phosphate in detergent?

Polyphosphate in the washing powder, has been excellent performance, safe and well known, is a good additive detergent. It has the important function of softening hard water, alkaline buffering, dispersing suspension fouling and washing efficiency.


is the phosphate in the detergent poisonous?

No. Phosphorus is the essential substance of life, each year about 700 grams of phosphorus intake from the diet, the discharge of more than 500 grams of phosphorus, phosphate in addition to used in detergent, at home and abroad as a statutory food additive use.


Does the liquid detergent contain phosphates?

Phosphate is generally not included. Because the liquid detergent requires the liquid to be emulsified evenly, add phosphate and other inorganic salts, it is easy to form precipitate, difficult to dissolve, so it is difficult to add phosphate. In particular, such as clothing softener, soap, kitchen, toilet and other hard surface cleaning agent does not contain "phosphorus", the current market liquid detergent annotated "no phosphorus" is not necessary.


What is color bleaching detergent?

Color bleaching detergent basic formula and ordinary washing powder is basically the same, the difference is the color bleaching detergent to add a certain amount of oxygen system bleach, such as sodium borate and over sodium carbonate. These oxygen system bleach is relatively mild, at room temperature will release active oxygen slowly, over 80 ℃ sodium borate, over 60 ℃ of sodium carbonate can have better bleaching effect. such as washing at low temperatures to add a certain amount of bleaching activator.


Can the color bleaching detergent remove the macular on the white collar?

OK. Because the macular is due to the protein on the collar of the dirt did not wash in time to be oxidized or excessive washing temperature caused the protein coagulation, oxidation metamorphism, with the help of the strong oxidation of bleach can remove macular. In order to avoid macular, white clothing should be long for long wash, washing water temperature can not be too high, preferably not more than 60 ℃.

What is whitening detergent and how do they work?

Whitening detergent is a common detergent based on the addition of fluorescent brightener. Fluorescent whitening agent is an optical whitening agent, which is adsorbed on fabric fibers during the washing process, and most of them still remain on the fibers after rinsing. The principle is to absorb the invisible ultraviolet rays and emit visible blue light to make up for and enhance the visual yellowing of white objects caused by blue-ray defects. At the same time it can also play a visual role in some color. Most of the new white clothes are fluorescent whitening treatment, after repeated use and washing, fluorescent whitening agent will be gradually removed. So cotton, hemp detergent contains whitening ingredients so that clothes look like new.


Is the detergency of the low foam detergent worse than the detergent?

The low foam detergent is relative to the high foaming detergent. The foam height has nothing to do with the decontamination force, and it has nothing to do with the type and quantity of lotion, mainly related to surfactant. Surfactant due to different types of foaming force size, detergent commonly used surfactants (alkyl benzene sulfonic acid sodium) Foaming force is high, bubble height for the mm (Roche method), and nonionic surfactant (ethylene oxide additive) foam lower than 180 mm, add oil soluble surfactants or defoaming agent can reduce foam. Add soap to detergent (fatty acid sodium), foam can be significantly reduced, this is due to soap in hard water to generate calcium soap, calcium soap is an oil-soluble surfactant with defoaming function, so the bubble is low, add some soap in use or in the solution of dissolved detergent powder to add liquid soap can be effective, This does not reduce the decontamination power of detergent.
