The most intuitive technical difference between concentrated laundry detergent and ordinary laundry detergent is reflected in the concentration of active ingredients. In ordinary laundry detergent, the core ingredients such as surfactants and detergents usually account for about 15%-20%, and most of the rest is water; while the active ingredient content of concentrated laundry detergent can be as high as 30%-50%, and some super-concentrated products even exceed 60%. This high-concentration formula allows a small amount of concentrated laundry detergent to achieve the cleaning effect of multiple times the amount of ordinary laundry detergent. For example, to wash the same weight of clothes, ordinary laundry detergent needs to be poured in 50 ml, while concentrated type only needs about 20 ml, which greatly reduces the single use amount.
Concentrated laundry detergent has been optimized in a lot of formula technology. In order to ensure the stability and fluidity of the product at high concentration, the R&D personnel adjusted the type and compounding ratio of surfactants by adding special thickeners and stabilizers, so that it can reduce water while maintaining a uniform liquid or semi-solid state. In addition, concentrated laundry detergents pay more attention to the addition and matching of biological enzymes and functional additives. For example, the encapsulation technology is used to microencapsulate the biological enzymes so that they can be accurately released during the washing process to improve the decontamination effect. In contrast, ordinary laundry detergents are limited by cost and technology, and there is a certain gap in the degree of refinement of the formula.
The production of concentrated laundry detergents has higher process requirements. In the raw material mixing link, more precise metering and stirring equipment are required to ensure the uniform dispersion of high-concentration ingredients; in order to reduce the viscosity of the concentrated liquid, special processes such as low-temperature mixing and vacuum emulsification are often used in the production process. At the same time, in order to ensure the stability of product quality, concentrated laundry detergents have stricter requirements on sealing during filling and packaging, and it is necessary to prevent moisture from entering and affecting product performance. Ordinary laundry detergents have relatively low production thresholds and costs due to their low ingredient concentration and relatively simple process.
From an environmental protection perspective, concentrated laundry detergents significantly reduce resource consumption. First of all, due to the high concentration of active ingredients, the use of concentrated laundry detergents is greatly reduced under the same washing effect, which directly reduces the consumption of raw materials. Secondly, concentrated laundry detergent reduces the addition of water, which greatly reduces the weight and volume of the product during transportation. Data shows that for laundry detergents with the same cleaning effect, concentrated ones can reduce the logistics transportation volume by about 50%, thereby reducing fuel consumption and carbon emissions, and reducing the pressure on the environment in the transportation link.
Concentrated laundry detergent has obvious advantages in reducing waste emissions. On the one hand, its small-dose packaging design reduces the use of plastic packaging materials. Based on the annual usage of laundry detergent in a family, the use of concentrated laundry detergent can reduce the consumption of plastic bottles by about 40% compared with ordinary laundry detergent. On the other hand, the amount of concentrated laundry detergent is small, and the total amount of chemical substances discharged with sewage during the flushing process is also reduced accordingly, reducing the pollution to the water environment. At the same time, since concentrated laundry detergent is easier to rinse clean, it can reduce the secondary pollution of clothes caused by residues, and indirectly reduce the waste of water resources caused by repeated washing.
The promotion and use of concentrated laundry detergent has positive significance for the sustainable development of the entire washing industry. It prompts enterprises to increase investment in research and development, promote the green upgrade of detergent formula and production process, and guide the industry to transform towards high efficiency, energy saving and environmental protection. In addition, consumers' recognition of concentrated laundry detergents will also help cultivate the concept of green consumption, form a good atmosphere for saving resources and protecting the environment in the whole society, and help achieve the "dual carbon" goal.
Although concentrated laundry detergents have many advantages, they still face some challenges in the promotion process. For example, some consumers have insufficient knowledge of concentrated laundry detergents and are accustomed to using them according to traditional dosages, resulting in poor cleaning effects; their relatively high unit price also discourages some consumers. In the future, enterprises need to strengthen product publicity, popularize correct usage methods, and further reduce production costs and improve product cost performance through technological innovation. With the improvement of environmental awareness and the improvement of industry standards, concentrated laundry detergents are expected to become mainstream products in the washing market and play a greater role in environmental protection and resource conservation.
