Zinc Pyrithione (ZPT) for Shampoo
General properties and applications
Is a mixture in water of very fine particles of zinc pyrithione, a dispersant, and a viscosity control agent.
Is an effective antidandruff agent.
Inhibits the growth of a broad spectrum of both Gram positive and Gram negative bacteria.
Inhibits the growth of fungi, both yeast and mold.
Inhibits the growth of algae.

Chemical incompatibility
Transchelation occurs in the presence of heavy metal ions. Even traces of the corresponding chelates can cause a noticeable discoloration, foremost the iron and copper complexes.
Is sensitive to strong oxidizing and reducing agents.
The Conductivity of water should be less than 5μs/cm Calculate the dosage to ensure that whole barrels of product would be added for each batch. It is recommended to add a little zinc salt to the water to ovoid occurring Fe(III) complexes when the conductivity of the water is less than 20μs/cm.
Is incompatible with EDTA, which, however, does no harm to the sterilizing effect of Zinc pyrithione

Remains stable for 120 hours at 100ºC, decomposes at 240ºC.
Is sensitive to light and remains stable in pigmented coatings.
Is hydrolytically stable between pH 4 and 8.5. Below pH 3.5 conversion to pyrithione occurs. In alkaline solutions (pH > 8.5) conversion to soluble alkali salts occurs.

Stores in original container in a dry and cool area away from direct sunlight with temperature between 10ºC and 54ºC. Keep container tightly closed and sealed until ready for use. Containers opened must be carefully resealed and kept upright to prevent leakage.
Agitate the barrels every 6 weeks. Pre-agitate for at least 10 minutes before using.
May be pre-dispersed by a certain amount of water to assure better dispersion. 
Calculate the dosage to ensure that whole barrels of product would be added for each batch.
