Application fields:
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 high-efficiency, environmental protection, hypotoxicity and broad-spectrum.

2. Piroctone olamine is a broad spectrum of microbiocide/microbiostat, may be used in formulating antidandruff shampoo, hair keep and hair care, soap, etc...It is also used as preservative and thickening agent.

Specification:
Solubility: Freely soluble in 10% ethanol in water; Soluble in solution containing surfactants in water or in 1%-10% ethanol; Slightly soluble in water and in oil. The solubility in water varies by pH value, and is a litter larger in neutral or weak basic solution than in acid solution.
pH: 8.5-10.0 (1% suspension in water, 20&deg; C)
PKa: 7.4
Thickening: Piroctone olamine increases the viscosity of many surfactant system.

STABILITY
A) pH: Stable in solution of pH 3 to pH 9.
B) Heat: Stable to heat, and to short time of high temperature above 80&deg; C Piroctone olamine in shampoo of pH 5.5-7.0 remains stable after one year of storage at a temperature over 40&deg; C
C) Light: Decompose under direct ultraviolet radiation. So it should be protected from light.
D) Metals: An aqueous solution of piroctone olamine degrades in the presence of cupric and ferric ions.

Compatibility
Piroctone olamine is compatible with many cosmetic ingredients, especially with cationic surfactants (tetramine salt) and cationic active components. In some cases, this re-mixture increase the solubility of piroctone olamine.
