ZPT is a superordinary anti-scale agent and anti-lipid overflow agent. It can effectively eliminate eumycete which produces dandruff, and result in relieving itching, removing dandruff,

diminishing phalacrosis and deferring poliosis. Therefore, it is considered as a highly effective and safe product. It will add the value of

shampoo and meet the high demands from consumers. For this reason, ZPT is widely used in the production of shampoo. Moreover, as a fine, broad-spectrum, environment -friendly and low toxic antiseptics, it can be used in civil coating, adhesive and carpet. The mixture of

ZPT and Cu₂O also can   be used as  marine antifouling coating to prevent adhering of shells, seaweeds and aquatic organisms to hulls.

 ZPT and its relative products enjoy tremendous potential and broad space in pesticide field with properties of highly efficiency,environmental protection, hypotoxicity and broad-spectrum.
