The bulk of the urine-recovered dye must have been taken up into the sexy layer of the skin and then slowly launched into the circulation. A cumulative 4-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 pores and skin areas showed slight erythema and excessive dryness. Mean information for 3 donors and sixteen replicates point out a plateau in receptor fluid concentration between 24 and forty eight h, as reflected by cumulative absorption values of 1. A regular-state permeability coefficient. For male albino rats pressure not given;.
Resorcinol is known to kind covalent bonds with haem Sessler et al. Effects on the thyroid gland have been reported each in animal research and in case-reports in humans. However, there are species differences within the susceptibility to goitrogens.
One issue rising potential poisonous results is the application of resorcinol to injured pores and skin Cassano et al. Surviving F zero parental and F 1 following selection rats underwent full gross necropsy following the breeding period seven F 0 males per group , following completion of weaning of F 1 pups F 0 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 obtainable on acute toxicity to different fish species.
- Other skin effects were hyperplasia, hyperkeratosis, irritation, and sebaceous gland hyperplasia, whereas there were no systemic treatment-associated lesions.
- Different studies carried out with rats and mice gave no increase within the micronucleus formation in bone marrow cells.
- The 14 C exercise was quickly distributed in main tissues such as muscular tissues, kidneys, and liver, with out indication of bioaccumulation Merker et al.
- Further particulars were not given.
- Under aerobic conditions, resorcinol proved to be readily biodegradable in a test performed based on OECD TG C, and it is more likely to be biodegraded under anaerobic conditions.
In , medical examinations see above and thyroid assessments have been performed with of presumably active plant staff males and 33 ladies. Flaked resorcinol caused no perceptible to moderate irritation intact pores and skin or no perceptible necrosis abraded skin.
Animals have 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 stomach walls and filling of abdomen and small intestine 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 modifications within the three ranges of the mind examined and within the absence of a dose—response relationship, other indicators of developmental delay, or different modifications in CNS function, these results were not thought of as conclusive evidence of a change in CNS perform. In the subsequent two-generation reproductive toxicity examine RTF, , these end-points were not investigated. No resorcinol-associated effects on F zero and F 1 pup survival or the general bodily situation of the pups through the pre-weaning interval had been observed.
More traditional-use conditions would result in exposures of about zero. Further particulars weren't given.
In rodents, the higher sensitivity can also be associated to a shorter plasma half-life of T 4 than in people due to considerable differences between species within 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 occasions higher in rodents than in humans.
