In English: Poly (iminocarbonimidoylimino-1,6-hexanediyl), monohydrochloride.

Synonyms polyhexamethylene guanidine hydrochloride: polyhexene (iminoimidokarboniminogeksametilen) hydrochloride.

CAS number: 57029-18-2.

The name in English and the structural formula polyhexamethylene guanidine hydrochloride: Poly (hexamethyleneguanidine) hydrochloride, (C7H16N3Cl) n, where n = 4-50, molecular weight: 700-10000 amu

Physical and chemical properties PHMG hydrochloride:

  • has no color or smell,
  • fireproof, explosion-proof,
  • completely soluble in water, soluble in alcohol,
  • not lose its properties at low temperatures,
  • not degraded and keeps its physical-chemical and biocidal properties to a temperature of 120 C °,
  • has coagulating and flocculating action,
  • pH 1% aqueous solution 7-10,5.
  • shelf life of 20% aqueous solution - at least 5 years, 100% concentrate - at least 7 years.

Biocidal properties PHMG hydrochloride:

  • it relates to a broad-spectrum antimicrobial biocide activity with respect to: Gram-positive and Gram-negative bacteria (including Mycobacterium tuberculosis, legionellosis)
  • viruses (including viruses of enteral and parenteral hepatitis, HIV, poliomyelitis, influenza, herpes, etc.),
  • fungi, including mold, yeast and yeast, fungi of the genus Candida, candidiasis, dermatophyte,
  • has algaecidal activity.
  • Other consumer properties:
  • has a deodorizing effect,
  • treatment surfaces gives longer bactericidal effect, which can be stored depending on the surface and other external factors from 3 days to 8 months, which makes this product unique biocide with the so-called "sustained release."

Toxicity PHMGH:

  • belongs to class 3 moderately hazardous substances when administered into the stomach,
  • to the 4th class of low-hazard substances when applied to skin in accordance with GOST 12.1.007-76. At a concentration of 0.05-4% of active material after a single skin contact causes no irritation,
  • using PHMGH in a concentration of 0.1-4% in the form of aerosols cause respiratory irritation, and in this case relate to the dangerous compounds.

The threshold limit value (TLV) polyhexamethylene guanidine hydrochloride:

  • in the working area - 2.0 mg / m3 (aerosol)
  • the threshold limit value in water reservoirs, in water bodies drinking and cultural and community water - 0.1 mg / L,
  • the threshold limit value - water fishery pond - 0.01 mg / l.

Product form:

  • in the form of pieces (pellets) with the content of polyhexamethylene guanidine hydrochloride by 95-98%
  • as an aqueous solution containing PHMG 20%
  • if necessary can be obtained from aqueous solutions of an active compound content of up to 50%.

History polyhexamethylene guanidine hydrochloride: the author of the original polymer synthesis belongs to an employee of the Institute of ecological and technological problems - the doctor of chemical sciences, Peter Alexandrovich Gembitskomu who started the release and implementation of PHMGH in the USSR.
