PHMB overview
> PHMB or PHMBG are the acronyms for PolyHexaMethylene Biguanide & Guanidine.
> PHMB P20 D, our standard product, is a 20%-PHMB solution, under its hydrochloride form, which general formula can be drawn as follows :
“n” (biguanides) being included between 12-31 and “m” (Guanidine) between 2-11.
> Biguanide and Guanidine groups are the active part of the PHMB.
Compared to other Biguanide compounds, the fact that Biguanide and Guanidine groups are in a polymer and separated by C6 aliphatic hydrocarbon chains gives this substance a particularly high efficacy on a wide range of microorganisms.
Its hydrochloric form implies PHMB has cationic properties.
> PHMB is not a Quaternary Ammonium Compound (QAC) but gives good synergetic disinfection solutions when blended with QACs.
> CAS Registry Number of PHMB :
PHMB is described by several CAS Registry Numbers, depending on its final form (hydrochloride or not), its polymerization precursors, ...
Paréva’s PHMB was initially notified under CAS [91403-50-8] and switched to [32289-58-0] for administrative reasons.
Since 2017, European Authorities stated that this substance is better described by CAS [1802181-67-4].

 In 1983, Mareva is created for developing and marketing Baquacil in France and german-speaking countries. « Baquacil » is the trade name of PHMB from Imperial Chemical Industry (I.C.I.) for the swimming pool water treatment sanitation.In 1988, after 7 years of work of both companies, Baquacil is registered for a 3-year period for its use as a public pools desinfectant. |
