What is the detergent

  Germany Henkel in 1907 to borate and silicate as the main raw material, the first invention of washing powder.Washing powder is a kind of alkaline detergent, washing powder is the main component of anionic surfactants: benzene sulfonate, a nonionic surfactant, and add some additives, phosphate, silicate, sodium sulfate, fluorescence, enzyme.Through mixing, spraying process made.Now most of 4A fluorspar instead of phosphate.  
 Synthetic detergent is a surfactant as main component, and an amount of different function builder.Washing powder is a powder (particle) of synthetic detergent.  
 Since the nineteen forties, with the development of chemical industry, people use oil to extract chemicals four polypropylene benzene sulfonic acid sodium, produced better performance than soap detergent.Then it also has improved softening hard water, detergent decontamination effect of phosphate with into the detergent, the detergent performance more perfect.People to use, carry, storage, transportation convenient, put into washing powder detergent manufacturing. 
 As a result of washing powder in water, river water, tap water, spring water, and even water and other various types of water have demonstrated good decontamination effect, and is widely used in various types of fabric, so the production and use thereof is developing rapidly.Now, the washing powder is almost every family must wash supplies.
Ingredients: laundry detergent compositions with a total of five major categories: active ingredient, helps wash composition, buffer composition, synergistic component, auxiliary component.
The main ingredients are: fabric anti scaling agent, anionic surfactant, nonionic surfactant, water softeners, dirt suspending agent, enzyme, fluorescent agent and spices; poor washing powder often contain phosphorus, aluminium, alkali and other harmful components.Surfactant in detergent is the role of the washing powder is soluble, emulsification, soak, sterilization, clean, soft, sparkling, clothing to prevent electrostatic function.Synthesis of surfactant was discovered to have thicker side effects such as the hand, is now regarded as a nuisance pollution environment.In addition, phosphorus, aluminum base, especially phosphorus in some developed countries have been banned from use in washing powder, however many our country chemical plant, still produce such products, especially some foreign enterprises, to his native products do not have these harmful substances, but in our country, then drill the law is not perfect, people environmental protection consciousness is not strong the loopholes, bold add these harmful substances.
Active ingredient
   Active ingredient Is a detergent components of.Washing active ingredient is a class called surfactant material, its role is diminished with stains clothes adhesion, in the washing water and rubbing his hands or a washing machine by mechanical force, so that the stains from clothes, so as to achieve the purpose of cleaning clothes.

Note: To achieve a good decontamination effect, should contain enough active ingredient in the detergent. In order to ensure the washing effect of the detergent, the national authorities provided for the lowest concentration of the active ingredient in the detergent. Active agent used in the type and product category, the detergent, the amount of active ingredient is generally not less than 13%;
2, because many surfactants have a strong foaming ability, consumers should be based on experience, to judge the pros and cons of the detergent from the foam of the case in the detergent soluble in water;
3, but some dedicated drum washing machine detergent, foaming ability than regular detergents worse a lot. This is because the drum washing machines rely mainly on clothes in the drum roll to produce mechanical force, to achieve the purpose wash clothes. Too much foam in the detergent solution, will be greatly reduced this mechanical force produced by clothes tumbling, making the wash so far been ineffective. Help wash composition
   Detergent in the washing powder is the largest amount of ingredients will generally account for 15% -40% of the total composition. The main role of the detergent is contained in the bound water hardness ions, so that the water to be softening to protect the surfactant to maximize the benefits. The so-called phosphorus, phosphate-free detergent, the actual use of detergent phosphorus or phosphorus substances.
Note: 1, some provinces and municipalities to develop local regulations prohibit or restrict the sale and use of detergents containing phosphates.
2, in the non-phosphorus detergent recognized by the industry can better alternative phosphate composition is a material called zeolite.
3 Furthermore, there are all kinds of cheap non-phosphorus detergent, such as sodium carbonate (soda ash), sodium silicate (water glass) and their percentage of complexes. Because these non-phosphorus additives are ultimately formed a water-insoluble precipitate, if you can not effectively be suspended in the water, they will sink to the clothing. The result will be long-term use of non-phosphorus detergent clothing harden, yellow. In order to prevent such situations occur, well-designed non-phosphorus detergent should be used in the formulation of effective dispersant, so that the formation of insoluble particles are not deposited in the clothing.
Buffer components
   The dirt on clothing, organic stains such as perspiration, food, dust, etc.. Organic stains are generally acidic, so that the washing solution in the alkaline state conducive to this type of stain removal, washing powder blended with a considerable amount of alkaline substances. Commonly used soda ash and sodium silicate.
Note: 1, although the alkaline conducive to the washing of clothes, but the excess of alkaline substances on clothing and skin harm, so countries alkaline detergent made ​​the corresponding provisions of the detergent should be qualified to meet these requirements.
In addition, as previously described in these alkaline substances will form precipitates with hard water, too much alkaline substances will lead to the formation of washing a lot of precipitation, but to make the washing effect of variation.
Synergistic ingredients 
to make the detergent has a better and more washing efficacy, more and more detergent containing the composition of the special features of these components can effectively enhance and improve the washing performance of detergents.
According to functional requirements, the detergent used in synergistic ingredients such categories: to improve the wash effect, such as enzymes (protease, lipase, amylase), bleach, bleach promoting agent; to improve the whiteness maintained, such as anti-redeposition agents, dirt dispersing agents, enzyme preparations (cellulase), fluorescent brighteners, anti-stain; protect the fabric to improve the fabric handle, such as softeners, cellulase, antistatic agent, color protection agentand so on.
Note: one, in fact, many brands of detergents in the main ingredient used in much the same, but the subtleties of the various products in these synergistic ingredients. The adoption of a variety of enzymes, can greatly enhance the detergent on the special and hard to wash the stains wash ability, such as blood stains, perspiration, food grease, vegetables, fruit stains, etc.; bleach make pigment stains are broken down to remove; anti-redeposition agents to ensure that the clothing repeated washing without gray hair yellow.
Auxiliary components
   To improve to improve the role of these ingredients are generally not the detergent from the washing ability, but to play a greater role on the processing of products, as well as the product of the sensory indicators, such as washing powder white color, uniform particles, no agglomeration, pleasant aroma Laundrythe scientific use of the powder
First, classification
   The detergent is a kind of synthetic detergent is essential household goods. Detergent on the market currently has the following three categories, each with distinct characteristics:
An ordinary detergent and concentrated laundry detergent:
  Ordinary washing powder, granules and loose, dissolve quickly, the foam is more abundant, but the detergency is relatively weak and difficult to rinse, generally suitable for hand wash; concentrated laundry detergent small particle size, density, foam less, but strong detergency(at least twice that of ordinary laundry detergent), easy to clean, water-saving, is generally suitable for machine washing.
Phosphorus detergent and non-phosphorus detergent
  Phosphorus detergent phosphate additives, phosphorus could easily lead to the environment, eutrophication, thereby undermining water quality, pollution of the environment. Phosphate-free detergent to no this shortcoming, water environmental protection. To the health of our living environment, it is recommended to use non-phosphorus detergent.
Enzyme detergent and fragrant laundry detergent
   Enzyme detergent in the detergent plus enzyme, flavored detergent washing powder added flavor. Enzyme detergent for specific dirt (juice, ink, blood stains, milk stains, gravy, milk, soy sauce stains, etc.), eliminate the special function of certain enzyme can also play a sterilization, whitening, color retention increase Yan et al. Flavored detergent at the same time meet the washing effect of clothing a sweet, makes people feel more comfortable.
