Daily chemical detergents are gradually becoming a necessity in today's society. Whether in the public **** place, luxury restaurants, or in every family, popular food stalls, we can see the chemical detergent traces. Every day, the news media such as radio, television, newspapers and magazines are also doing a lot of advertising of chemical detergents. In the process of using these colorfully packaged chemical detergents, people are unconsciously becoming dependent on them as if they were addicted to them. While using chemical detergents uncontrollably, chemical pollution jeopardizes human health through various channels. That is why some scientists, in the spirit of responsibility for human beings, have raised the issue of re-conceptualizing chemical detergents. For example, after more than 20 years of investigation, experimentation, and reports of consumer harm, the Japanese Consumers Union, an authoritative organization in Japan, exclaimed, "Chemical detergents can no longer be used!" Chemical detergent is actually a by-product of the development of petroleum waste. Because it dissolves in water, it has been ignored for what it is. At the same time, because of its low cost and good detergent performance, once discovered, it was quickly accepted by the people and packaged up into the society with the blindfold of color and smell. The washing ability of chemical detergents mainly comes from surfactants. Because the surfactant can reduce the role of surface tension, can penetrate into the fibers even water can not penetrate the empty space, the dirt hidden in the fibers in the empty space to squeeze out. Chemical detergents, on the other hand, are trapped in these voids, making it difficult for water to clean them. Similarly, surfactants can penetrate the human body. About 0.5% of the detergent on the skin enters the bloodstream, and if there is a wound on the skin, the penetration is increased by a factor of 10. Chemical detergent toxins that enter the body can reduce the concentration of calcium ions in the blood, acidify the blood, and make people easily tired. These toxins also reduce the detoxification function of the liver. So that the original toxins should be discharged out of the body stagnation in the body into a large number, so that people's immunity decline, liver cell lesions intensified, easily induced cancer. The toxicity of chemical detergents will increase several times when they are combined with other chemical substances after invading the human body. Especially, it has strong cancer-inducing properties. It has been reported that artificial experiments of cultivating stomach cancer cells and injecting LAS, the basic substance of chemical detergents, accelerated the deterioration of cancer cells, and that LAS is highly blood-soluble, causing changes in hemoglobin and resulting in anemia. The proliferation of chemical products is the biggest root cause of the increasing number of cancers in human beings, and chemical detergents are the most direct and closest household products for human beings. People in the extensive use of chemical detergents to wash hair, dishes, clothes, bath at the same time, chemical toxins from millions of pores seeping, the human body is in the night and day drug addiction, chemical contamination from the mouth seepage, from the skin seepage, day after day, latent agglomeration. Since the harm of this pollution is unlikely to be obvious in a short period of time, it is often overlooked. However, trace amounts of pollution continue to enter the body, and the accumulation of small amounts can cause serious consequences, leading to a variety of pathologies in the human body. The urbanization of human life is unavoidable, and so is the reliance on detergents in urban life. Therefore, the improvement of detergents, the use of non-hazardous, non-destructive environment, non-toxic and non-polluting detergents has become an urgent task, in the world's call for "environmental protection", "save the planet" in the call, many countries put their hopes in the oceans. From the inexhaustible, inexhaustible seawater in the refining of natural detergents is the desire of all mankind can not wait. As far as 3000 years ago in the Middle East near the Dead Sea residents know how to use seawater to purify the body; on the eve of the First World War, Germany is researching from seawater in the refined detergent; 80's in the Japanese pharmacy can be bought medical seawater detergent, this detergent is close to non-toxic and harmless standards. In China, there have also been used to wash hair with egg whites, with soapnut soaking water to wash clothes and other practices recorded, which also shows that the development of detergents in natural resources is a wide range of prospects. When people gradually recognize and understand the harm of chemical detergents, will accelerate the pace of development of natural detergent resources, in order to make people healthier, more progressive and strive for social progress.
