  INTRODUCTION
The HESTERQUAT BKC - 50, is a version of BENZALKONIUM CHLORIDE aqueous solution. Is the best known and widely used, as a germicide, of all the Quaternaries Ammonium. The BENZALKONIUM CHLORIDE, as generally mentioned, is obtained, from high purity coconut oil fatty acid, following strict specifications of the international pharmacopeia,
It is a stable product under a wide range of PH, which grants his solubility and activity under any PH value. The absorption and the anti-microbial effect of HESTERQUAT BKC - 50, increases according with the PH increase. In the chart below, is possible to verify the anti-microbial power related with an elevated PH, considering that the values offered are for low concentrations in mg/Liter of HESTERQUAT BKC-50, which reduces the number of microorganisms by a factor of 10.000 after 5 and 10 minutes respectively.
