Molecular structure determines performance, and performance and determine its scope of application. Gemini surfactant unique structure determines its unique performance, unique properties make it a special application. For example, in cosmetics, low cmc means Gemini surfactant is smaller than ordinary surfactants irritating to the skin. This is because the skin irritation from nonmicellar of general agents, cmc lower values ??mean in solutions-based surfactant (monoric surfactant) less. Gemini Surfactant cmc showed lower values ??than ordinary lower concentration of the active agent can be dissolved in a water-insoluble substance, because only when the concentration exceeds cmc dissolution will occur and so that the water-insoluble substances into micelles rather it is dissolved. American Chemical Manufacturers Association reached an agreement with the US Environmental Protection Agency, OP-10 price, using a practical approach, sampled effluent discharge located downstream river area, shelf OP-10, impact on NPEO and its metabolites were tested ??? Rivers survey database provided by the US EPA in total river 68000, Zhangjiakou OP-10, remove sewage and no non-flowing rivers and lakes, as well as 54, to choose the typical 30 river sampling "[8, 9] Sample tests showed 90% sample NP and NPEO1 concentration ≤0.3 ug / L (ppb), NPEO2 concentration ≤0.4ug / L, NP in the river, the highest value 0.64ug / L, supply OP-10, the highest concentration in river sediments is 2 960, ug / L. The most sensitive aquatic organisms at NP concentrations of 6.7-14.0 ug / L poisoning can occur when, NP concentration of 34 200ug / You can make L sojourn in river sediments when the organism poisoning sampling 30 rivers, NP, NPEO1 and distribution form NPE02 somewhat similar.
