Specification:
Appearance White or slightly yellow crystalline powder
Identification Positive
Odor Almost odorless
Content Not less than 98%
Melting point 130 - 135℃
Loss on drying Not more than 0.3%
Ash (SO4) Not more than 0.2%
PH value (1% aq. solu. 20℃) 8.5 – 10.0
Heavy metals Not more than 20ppm
Amino Ethanol 20.1 to 20.9% dried base
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.
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℃. DF-206 in shampoo of pH 5.5-7.0 remains stable after one year of storage at a temperature over 40℃.
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.
