octpirox (pyridine-amino ethanol salt)
The new removing dandruff antipruritic of superior performances Summarize
octpirox is the latest international removing dandruff antipruritic products developed by Germany Hurst Company in the 1980s. Its unique performances are following : 1, To dandruff and antipruritic better than similar products; 2, dissolved performance and complex performance are wonderful , mixed with cosmetics raw materials will be no precipitation or layered; 3, having unique mechanism for removing dandruff, low stimulate, will not cause hair loss and hair broken, security is better to the similar To dandruff antipruritic products.
CTFA named:
1 - hydroxy-4 - methyl -6 - (2,4,4 - III-E) -2 - pyridine - (2 - amino ethanol) salt
The performance and mechanism of removing dandruff and antipruritic .
octpirox is the products of efficiently removing dandruff, low stimulate and non-toxic can be widely used in the removing dandruff shampoo, hair care and conditioner. According to its final product different, octpirox amount is generally 0.1% -0.5%, while in the hair care and conditioner, to reduce the amount of 0.05% -0.1%, can achieve the very satisfied results.
The mechanism of octpirox removing dandruff and antipruritic is blocking the outside channels of dandruff producing from the fundamentally through the use of disinfection and anti-oxidation, thus curing dandruff and Itch effectively, rather than on temporary. This is one of the reasons of octpirox better than the similar products.
Physical and chemical properties:
octpirox is crystal powder with white or pale yellow, very short characteristic odor, and the natures with cosmetics are as follows:
Solubility
Fine solubility performance, is a significant advantage from the similar products. It can soluble in water and ethanol, PH value impacts the octpirox solubility a lot. Generally speaking, it has a larger solubility in neutral or weak alkaline.
Impaction of PH
octpirox is stability in PH3-9. In neutral conditions, octpirox is free acid .PH 7.4.
Thermal stability
octpirox has good thermal stability, in the production process, such as temperature occasionally over 80C will not affect the performance of octpirox In addition, the shampoo with octpirox (PH5.5 and 7.0) in 40 C can be stored for one year.
Light stability
Under the direct of UV, active components of octpirox can be decomposed. So the storage of octpirox is in dark as much as possible.
Impaction to viscosity
Adding octpirox can make many surfactant systems increase the viscosity.
Other physical and chemical indicators
Active component: ≥98.0%
Molecular weight: 298.4g/M
Melting point: 130-135C (decomposition)
Dry weight loss: ≤2.0%
Sulfate ash content: ≤0.2%
PH (1%water suspension, 20C): 8.5-10.0
Nature of security
The security on the eyes and skin of octpirox tested by the department of drug-testing in German is very reliable. Absolutely non-toxic, non-provocative and will not cause allergic. In actually will not damage the scalp, no hair will loss and be broken.
