Detailed explanation of washing powder ingredients
To put it simply, there are five categories of detergent ingredients: active ingredients, washing ingredients, buffering ingredients, synergistic ingredients, and auxiliary ingredients.
 
The main ingredients are: fabric fiber antifouling agent, anionic surfactant, non-ionic surfactant, water softener, dirt suspension agent, enzyme, fluorescent agent and perfume, etc.; poor washing powder often contains phosphorus, aluminum, alkali, etc. Harmful ingredients. The role of surface active agent in washing powder is to make washing powder have the functions of soluble, emulsified, soaked, clean, sterilized, softened, foamed, and prevent clothes from static electricity. Synthetic surfactants have long been found to have side effects such as thickening of hands, and are now regarded as a major public hazard that pollutes the environment. In addition, phosphorus and aluminum alkali, especially phosphorus, have been banned from being used in washing powders in some developed countries. However, many chemical plants in China are still producing such products, especially some foreign-funded enterprises, which cannot be used in their own local products. These harmful substances, but in our country, we take advantage of the lack of sound laws and people's weak environmental awareness, and boldly add these harmful substances.
 
Active ingredient
The active ingredient is the ingredient that plays the main role in the detergent. The detergent active ingredient is a kind of substance called surfactant. Its function is to weaken the adhesion between stains and clothes. Under the action of washing water, hand rubbing or washing machine agitation and other mechanical forces, the stains are separated from the clothes, thereby To achieve the purpose of washing clothes.
 
Notice:
1. To achieve a good decontamination effect, the washing powder should contain enough active ingredients. In order to ensure the washing effect of washing powder, the national competent authority has stipulated the minimum content of active ingredients in washing powder. According to the type of active agent used and the category of the product, the amount of active ingredient in the washing powder should generally not be less than 13%;
2. Because many surfactants have strong foaming ability, consumers can judge the pros and cons of the washing powder from the foaming situation of the washing powder after dissolving in water based on experience;
3. However, some washing powders specially used for drum washing machines have much worse foaming ability than ordinary washing powders. This is because the drum washing machine mainly relies on the mechanical force generated by the tumbling of the clothes in the drum to achieve the purpose of washing the clothes. Excessive foam in the washing solution will greatly weaken the mechanical force generated by the tumbling of the clothes, and the washing effect will be greatly reduced.

Washing ingredients
The builder in washing powder is the most used ingredient, generally accounting for 15%-40% of the total composition. The main function of the builder is to soften the water by restraining the hardness ions contained in the water, thereby protecting the surfactant to maximize its effectiveness. The so-called phosphorus-containing and non-phosphorus detergents actually refer to whether the builders used are phosphorus-based or non-phosphorus-based substances.
 
Notice:
1. Some provinces and cities have formulated local regulations to prohibit or restrict the sale and use of phosphate detergents.
2. Among the non-phosphorus builders, the one recognized by the industry as a good substitute for phosphate is a substance called zeolite.
3. In addition, there are various "cheap" non-phosphorus builders, such as sodium carbonate (soda ash), sodium silicate (water glass) and their various proportions of complexes. Since these phosphorus-free additives eventually form water-insoluble precipitates, if they cannot be effectively suspended in water, they will sink on the clothes. The result of long-term use of this non-phosphorus detergent will make the clothes hard and yellow. In order to prevent this from happening, a well-designed non-phosphorus detergent should use an effective dispersant in the formulation so that the formed insoluble particles will not be deposited on the clothes.
 
Buffer component
Common dirt on clothing is generally organic stains, such as sweat stains, food, dust, etc. Organic stains are generally acidic. Keeping the washing solution in an alkaline state facilitates the removal of such stains. Therefore, detergents are mixed with a considerable amount of alkaline substances. Soda ash and water glass are commonly used.
 
Notice:
1. Although alkaline is beneficial to the washing of clothes, excessive alkaline substances will cause damage to clothes and skin. Therefore, the country has made corresponding regulations on the alkaline of washing powder, and qualified washing powder should meet these requirements.
2. In addition, as mentioned above, these alkaline substances will form precipitation with hard water, and too much alkaline substances will cause a large amount of precipitation during washing, which will make the washing effect worse.

Synergistic ingredients
In order to make detergents have better and more washing-related effects, more and more detergents contain ingredients with special functions, which can effectively improve and improve the washing performance of detergents.
According to functional requirements, there are several types of synergistic ingredients used in detergents: those that improve the cleaning effect, such as enzyme preparations (protease, lipase, amylase, etc.), bleaching agents, bleaching accelerators, etc.; those that improve whiteness retention , Such as anti-redeposition agents, soil dispersants, enzyme preparations (cellulase), fluorescent brighteners, anti-dyeing agents; protect fabrics and improve fabric feel, such as softeners, cellulase, antistatic agents, color retention agents Wait.
 
Notice:
In fact, many brands of detergents are similar in the main ingredients used, and the mystery of each product is often in these synergistic ingredients. The use of various enzyme preparations can greatly enhance the detergent's ability to clean special and difficult-to-wash stains, such as blood stains, sweat stains, food oil stains, vegetable and fruit stains, etc.; bleaching agents can decompose and remove pigment stains; The depositing agent can ensure that the clothes will not turn gray and yellow after washing for many times.
 
Auxiliary ingredients
Such ingredients generally do not improve the washing ability of detergents, but they have a greater effect on the processing process of the product and the sensory indicators of the product, such as making the washing powder white in color, uniform in particles, non-caking, and pleasant aroma, etc.
