Q:
What is Chloroxylenol PCMX CAS 88-04-0?
A: Chloroxylenol PCMX CAS 88-04-0 is 4-chloro-3,5-dimethylphenol, a substituted phenol with the molecular formula C8H9ClO and molecular weight 156.61 g/mol. It is used as an antimicrobial active in personal care and household disinfectant products. -
Q:
Why is PCMX used in antiseptic soaps and liquid disinfectants?
A: PCMX provides broad antimicrobial activity and is compatible with many surfactant systems. It is commonly formulated with solubilizers such as alcohol or pine oil because its water solubility is low. -
Q:
What are the typical physical specifications for Chloroxylenol?
A: Commercial material is generally a white or cream crystalline powder with a characteristic phenolic odor, assay of about 98.5% or higher, and a melting point around 114-116 C. It is more soluble in organic solvents and alkaline solution than in water. -
Q:
What is the antimicrobial spectrum of PCMX?
A: It is active against many Gram-positive bacteria and is used for antibacterial applications, but it is less effective against some Gram-negative organisms and bacterial spores. For finished formulations, use level and contact time should be based on the intended product and applicable testing. -
Q:
What handling precautions apply to Chloroxylenol PCMX?
A: PCMX may be harmful if swallowed and can irritate the eyes and skin, with potential for skin sensitization. Handle with appropriate PPE, provide ventilation, and follow local regulations for storage and waste disposal.
