Chlorocresol appears as a pinkish to white crystalline solid with a phenolic odor. Melting point 64-66°C. Shipped as a solid or in a liquid carrier. Soluble in aqueous base. Toxic by ingestion, inhalation or skin absorption. Used as an external germicide. Used as a preservative in paints and inks.
颜色/状态:
Dimorphous crystals ... aqueous solutions turn yellow on exposure to light and air
气味:
Said to be odorless when very pure, but usually a phenolic odor persists
Four groups of conventional female albino guinea pigs, three per group, were used to determine the bioavailability of PCMC. Occlusive patches of 0.2 mL of a 5% PCMC aqueous suspension stabilized with Carbomer 941, a saturated aqueous solution of 0.38% PCMC, 5% PCMC in olive oil/acetone (4:1), or 5% PCMC in propylene glycol were applied for 24 hr. After 96 hr, the animals were killed and the skin at the site of patch testing was removed for analysis (the patches were kept for analysis to determine the amount of PCMC remaining in the patch material). Fractional sampling of the urine and feces was performed to determine the rate of absorption of PCMC. An additional three animals had been injected with PCMC intraperitoneally to determine the excretion rate. However, no free PCMC was found, indicating rapid metabolism. In determining bioavailability, the calculations were based on the assumption that the saturated PCMC solution is 0.4% (w/v), corresponding to 0.8 mg in 0.2 mL, and that 0.2 mL of the 5% PCMC preparations contained 10 mg of the chemical. The results indicated that 25% of the aqueous PCMC (stabilized with carbomer 941) and 46% of the saturated aqueous PCMC solution remained in the patches. Only 0.2% of the aqueous PCMC (stabilized with carbomer 941) and 0.5% of the saturated aqueous PCMC solution was found in the skin at the patch site. This was compared to 65% of the PCMC in propylene glycol and 66% of the PCMC in olive oil/acetone solutions remaining in the patch; and 0.7% and 1.6%, respectively found in the skin at the patch site. The authors conclude that PCMC was more bioavailable from the aqueous preparations. After 96 hr, 0.2 and 0.5% PCMC was detected at the patch test site in the animals dosed with 5% and saturated aqueous PCMC, respectively, and 0.7 and 1.6% PCMC were found in the skin of the animals patch tested with 5% PCMC in olive oil/acetone and propylene glycol, respectively.

杀菌剂4-氯-3-甲基苯酚(CMP,CAS号59-50-7)是金属加工液(MWF)和建筑材料的常见添加剂。在当前研究中,评估了TRIM VX工作稀释液(20%水溶液)中CMP的人体表皮渗透性,并为了比较,还评估了从水缓冲液中的渗透性。还测量了从短暂接触20% TRIM VX的CMP渗透。将表皮膜短暂(20或40分钟)暴露于20% TRIM VX(样本量=4)分别导致总渗透量为4.2 +/- 1.2和7.3 +/- 0.8微克/平方厘米。
The biocide 4-chloro-3-methylphenol (CMP, CAS number 59-50-7) is a common additive to metal-working fluids (MWF) and building materials. ... In the current study, the in vitro human epidermal permeability of CMP contained in a working dilution of TRIM VX (20% in water) was evaluated and, for comparison, permeability from an aqueous buffer was also assessed. CMP penetration was also measured from transient exposures to 20% TRIM VX. ... Transient (20 or 40 min) exposures of epidermal membranes to 20% TRIM VX (/sample size/ = 4) resulted in total penetration of 4.2 +/- 1.2 and 7.3 +/- 0.8 ug/sq cm, respectively. ...
A pharmacokinetic study was performed in which rats were dosed orally with 300 mg/kg PCMC. PCMC reportedly was eliminated rapidly through the kidneys. Additionally, there is no likelihood of cumulation effects. A corresponding examination of fatty and hepatic tissues from rats that were fed 150-1500 ppm PCMC for up to 13 week reported no indication of an accumulation of PCMC in these tissues.
Rabbits were injected subcutaneously with 1 g 3-methyl-4-chlorophenol/kg bw dissolved in olive oil. 15-20% of the 3-methyl-4-chlorophenol given was excreted (urine) during 4-5 days.
