Tableware detergents use more mild surfactants

Consider the characteristics of surfactants. The critical micelle concentration (CMC), which is the low concentration of surfactant micelles in solution, is related to the appropriate dosage of surfactant. There is cloud point phenomenon in polyoxyethylene nonionic surfactant, that is, when the temperature is low, the oxygen atom of polyoxyethylene ether of nonionic surfactant is connected with water molecule by hydrogen bond, so it is easy to dissolve in water and become a clear solution. When the temperature rises to a certain extent, the molecular thermal movement increases, the hydrogen bond will be destroyed, and the surfactant will precipitate and separate in water, which is originally transparent The solution turned into a white, cloudy emulsion. The temperature at this time is called cloud point. The cloud point value is related to the high temperature allowed for the use of nonionic surfactants.

By adding high effective stabilizer into industrial cooling water, once through cooling water (disposable water) can be changed into circulating cooling water, thus saving a lot of fresh water resources. From the perspective of green chemistry, the new type of corrosion inhibitor is to replace the original chromate and dichromate with platinum salt, and replace aromatic amine with aliphatic amine. Its toxicity and pollution are significantly reduced, such as replacing the original organic chromium phosphate and phosphate with green product polyaspartic acid.

Reclaimed water is a kind of non drinking water that can be used in industrial and agricultural production after domestic sewage and industrial sewage are treated by green chemical technology. In recent years, with the shortage of fresh water resources, people pay more and more attention to the production of reclaimed water. In China, reclaimed water production plants with a certain scale have been built in Beijing, Shanghai and other places.

Surfactant in dishwashing detergent does not directly enter the human body as a component in medicine or food formula, but only a little remains on the surface of tableware, so the safety requirements of surfactant are slightly lower than those in medicine or food, But it ended because of lack of sufficient evidence

The new choice is to use more mild surfactants such as APG, sugar ester, sulfosuccinate, castor oil amide propyl betaine as the main agent to create a new safe and mild formula, The test results show that the irritation of the original formula can also be reduced by one level
