CHARACTERISTICS
* 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°C)
* pKa: 7.4
* Thickening: Piroctone olamine increases the viscosity of many surfactant system.
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.
