 STRATEGIC AND TACTIC SUPERIORITIES OF MARCOMER--

     Substituts of Sodium Tripolyphosphate in 
             "Environment Friendly Detergent"Production

（A) Requirement of Ecotop and Environment Protection Policy

    In order to reduce the Eutrophication of Water-Resource, more than twenty three states have limited the use of sodium tripolyphosphate in detergents, and more than eight other states are considering such moves. In Europe: Germany, Austria, Switzerland, and Italy polyphosphate content of detergent is regulated by law. In China in some area, such as: Wuxi, Hangzhou, Kunming, Xishuangbanna, polyphosphate content also has been regulated by law.
    Therefore, Marcomer-the substitut of sodium tripolyphosphate is arisen at the historic moment.

（B) Technical Advantage

 1. Superior Performance of Macromer comparing with sodium tripolyphosphate:

• Strong adsorption on particulate-soil at low concentration;

• Pronounced dispersive effect on particulate-soil and lime-soap-soil;

• Useful in preventing scale-CaCO3-formation and precipitation;

• High buffer capacity on pH value;

• Good compatibility with detergent constituents;

• Support of the active detergent surfactants in soil removal;

2. Sufficient cleaning properties of "Environment Friendly Detergent" when Marcomer can be used as the substitute.

    Primary Detergency---Defined as the whitening effect, the bleaching effect and the soil-and fat-removing effect can be kept on;
  Secondary Detergency---comprises the situation of deposition (encrustation), graying of fabric and scale on washing machine after several washing cycle can be distinct improved. The following special performance will be possessed by "Environment Friendly Detergent":
    Anti-redeposition of soil on fabric;
    Scale inhibition of washing machine;
   Marcomer series are developed by Nanjing Zhong-yi Chemical Technology Development Research Institute.
   President of Nanjing Institute, Mr Li Shouchun was the visiting scientist of University of Rome "La Sapienza", and the chief leader of IRESMO Environment Department. He had got the first class Science and Technology Research Fruit Prize in China IN 1982. Marcomers are, his many year research fruits, and stay on the advanced level at home and abroad.
