THE LABEL OF A PRODUCT
('what did you find out')
First, we use the label of a detergent which was found in Tim's house.
1.We found the surfactant(表面活性剂) and the washing aid/builder(助洗剂)on the Main ingredients label.
2.Unfortunately,both of them are unfamiliar to us.
3.The similarities: They are all compounds and mixtures; All of them can make chemical reactions; Most of them might be dangerous to people.
The differences: Each of them has their unique effect. For example, the surfactant is used for cleaning up the dirt on the surface of the object. The washing aid/builder is made of sodium silicate and sodium carbonate. It is used to dissolve the dirt and wash them away.
4.Yes, we do. The products that are labeled “green” are low-pollution, non-pollution or even Beneficial to our environment. Most of them can be recycle after being used up. But the other kinds of products may cause serious problems. Like decreasing the nutrition of the soil.
5. They will cause us some health problems if we use the bowls or plates which were wiped with so much detergent without cleaning it.
6.No, I do not think so.Because, although they may cause problems to our world, they are convenient for our lives. They even made an huge contribution to the development of the industries. We think it will be great for the human race if we create some new products for the world.
7.Surface active agent (surfactant) is a substance which can make the interface state of the solution system change obviously, and has a fixed hydrophilic and lipophilic group,it has an adsorption.
