PCMX is a widely used biocide active against bacterial and fungal growth in a wide range of applications. The product is a white crystalline solid and can easily be formulated into soaps, detergents, antiseptics, disinfectants and many other products. Description PARA CHLORO META XYLENOL (PCMX) is an exceptionally broad spectrum bactericide and preservative with a long established and proven use in controlling bacteria, mildew and fungal growth in a wide range of applications (medical, domestic and industrial). Physical and Chemical Properties Synonyms: Para Chloro Meta Xylenol, PCMX 4 chloro 3,5-dimethyl phenol, 4 chloro 3,5 xylenol, 4 chloro meta xylenol "Chloroxylenol" (British Pharmacopoeia). CAS number: 88-04-0 Typical Properties Form crystals or crystalline powder Odour characteristic Melting Point °C 114 - 116 Purity: 98.5 % Min Antimicrobial Activity PCMX is a bactericidal active which, in a large number of differing formulations, has been proved over many years to be highly efficient against a wide range of microorganisms. PCMX is bactericidal, not merely bacteriostatic and control is afforded versus fungi, gram positive, gram negative bacteria and some viruses. Many virus types are resistant to chemical germicides including PCMX but can be controlled by the use of easily formulated mixtures of PCMX and other bactericides. Other general advantages of PCMX preparations when compared with other bactericidal agents are: ? PCMX is compatible with a wide range of anionic and amphoteric surfactants and soaps and formulation is easy. Pine oil is a useful carrier and adjunct for PCMX and bactericidal activity can be enhanced by its use. ? For various applications PCMX may be formulated with other chlorinated phenols, sulphur and quaternary ammonium compounds. It is compatible with a wide variety of pharmaceuticals including hydrocortisones, pramoximes, propylparaban and sulphathiazoles. ? Dirt and particulate soil can inactivate all bactericides to a greater or lesser extent. PCMX based formulations are more tolerant than most in this respect. ? PCMX is bactericidally active over a pH range of at least 4 - 9. ? PCMX exhibits low metal corrosivity; an important factor where instrumentsterilization is involved.
