hot water. Soluble in 1 part of 95% alcohol, ether, benzene, terpenes,
fixed oils, in solns of alkali hydroxides.
3. Excellent stability.
4. Low toxicity. Acute oral toxicity: LD50> 3000 mg / Kg (rat), acute injected toxicity: LD50> 2000 mg / Kg (rat).
IV. Application
1. Application Fields
① Hospital and common medicinal use
PCMX can be applied to preoperative skin degerming, sterilization
of medical equipment, and daily cleaning of the surfaces of equipment
and hard objects. To prevent cross infection, it can be used for
producing medical antibacterial soaps, athletes foot bactericides and
general first-aid medicines. PCMX can be prepared into liquid, anhydrous
hand cleaner, powder, cream, lotions and other preparation types, and
can also be used as a preservative in other medicines.
② Household and daily sterilization
PCMX can be used as bactericide and insecticide for skin wounds
(liquid, cream and lotion),common disinfectant and washing disinfectant,
sterilization soaps and personal hygiene care hand sanitizer and
shampoo (particularly the products with anti-dandruff functions).
③ Industrial use
Coating surface: In the damp environment, PCMX is used as a fungicide to be applied to the paint.
Glue and adhesive: PCMXC can prevent microorganisms decomposing and
producing peculiar smell, clogging the filter and corroding metals, and
the product failure.
Leather treatment: PCMX can prevent molding and resist the attack
of bacteria and fungus (particularly for salted leather, plant leather
and salted or air-dried green hide).
2. Dosage
Generally used at a concentration of 0.2 ~ 5.0% (w / w).
3. Application method
PCMX is added into alcohol, benzene, ether and other solutions, and
then is mixed with other materials. Some nonionic or anionic
surfactants can completely dissolve PCMX without the generation of any
clusters.
