Antiseptic and mould proofing effects:

This product can restrain and sterilize eight moulds, five bacteria as well as two yeast fungis which are distillery yeast and bakers’ yeast.

Its MIC to various micro-organisms is as follows:

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.

Stability: remain stable for 2 years, avoiding light .
