The bulk of the urine-recovered dye should have been taken up into the horny layer of the skin after which slowly released into the circulation. A cumulative four-day absorption assuming cm 2 of scalp was given as zero.

The acute dermal toxicity of resorcinol was studied in male albino rabbits Koppers Company, Signs of intoxication included salivation, tremors, and convulsions, and handled skin areas showed slight erythema and extreme dryness. Mean information for 3 donors and 16 replicates indicate a plateau in receptor fluid focus between 24 and forty eight h, as mirrored by cumulative absorption values of 1. A steady-state permeability coefficient. For male albino rats pressure not given;.


Resorcinol is known to form covalent bonds with haem Sessler et al. Effects on the thyroid gland have been reported each in animal research and in case-stories in humans. However, there are species differences within the susceptibility to goitrogens.

One factor rising potential toxic effects is the applying of resorcinol to injured skin Cassano et al. Surviving F 0 parental and F 1 following selection rats underwent complete gross necropsy following the breeding interval seven F zero males per group , following completion of weaning of F 1 pups F zero females , following scheduled necropsy of F 0 females remaining seven F zero males per group , on PND 28 F 1 exposed pups , or on PND 30 or 70 F 1 pups chosen for behavioural testing.

  • There are a number of studies available on acute toxicity to totally different fish species.

  • Other skin effects were hyperplasia, hyperkeratosis, inflammation, and sebaceous gland hyperplasia, whereas there have been no systemic therapy-related lesions.

  • The bulk of the urine-recovered dye must have been taken up into the attractive layer of the pores and skin and then slowly released into the circulation.

  • Different research performed with rats and mice gave no improve in the micronucleus formation in bone marrow cells.

  • Especially in rats, lengthy-time period perturbations of the pituitary—thyroid axis brought on by xenobiotics or physiological alterations e.

In , medical examinations see above and thyroid assessments were carried out with of presumably lively plant staff men and 33 women. Flaked resorcinol triggered no perceptible to average irritation intact skin or no perceptible necrosis abraded skin.

Animals had been maintained for several months with periodic sacrifices Flickinger, The animals had been then examined weekly for 10 extra weeks. Sacrificed animals confirmed brown-dyed abdomen walls and filling of stomach and small gut with a dark-brown to orange substance. These findings weren't noted in survivors.

The results had been extra pronounced at seventy two h. The irritation index was given as four. However, owing to lacking correlating histopathological adjustments in the three ranges of the brain examined and in the absence of a dose—response relationship, different indicators of developmental delay, or different modifications in CNS operate, these effects weren't thought of as conclusive proof of a change in CNS function. In the next two-era reproductive toxicity examine RTF, , these end-factors were not investigated. No resorcinol-associated effects on F 0 and F 1 pup survival or the final physical situation of the pups during the pre-weaning interval were noticed.
More ordinary-use conditions would result in exposures of about 0. Further particulars weren't given.
In rodents, the upper sensitivity is also related to a shorter plasma half-lifetime of T four than in humans as a result of considerable variations between species in the transport proteins for thyroid hormones. In plasma, the T 4 half-life is about 12—24 h in rats vs 5—9 days in people, and the serum ranges of TSH are about 25 instances larger in rodents than in humans.
