Determination of resorcinol conjugates in the h urine samples after 14 days of steady product therapy confirmed that a maximal 23 mg 2. Assuming a physique weight of sixty four kg IPCS, provides an exposure estimate of zero. In a report based mostly on client research information Gans, , underneath cheap most-use situations i.

Resorcinol is thought to type covalent bonds with haem Sessler et al. Effects on the thyroid gland have been reported both in animal research and in case-reviews in humans. However, there are species variations in the susceptibility to goitrogens.
The bulk of the urine-recovered dye should have been taken up into the attractive layer of the skin after which slowly launched into the circulation. A cumulative four-day absorption assuming cm 2 of scalp was given as 0.


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





  • Of the following studies, the repeated-dose toxicity research that had been deemed to be most related to the risk assessment are summarized in Appendix 6.




  • 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 confirmed slight erythema and extreme dryness.




  • In http://www.filedropper.com/fsyle of a full life cycle toxicity take a look at OECD TG , Lima noticed no antagonistic effects after 48 h of publicity at the highest focus tested, 0.




  • Sacrificed animals confirmed brown-dyed abdomen partitions and filling of stomach and small intestine with a dark-brown to orange substance.




  • The microscopic examination of the thyroid gave minimal changes follicular hyperplasia , which had been statistically not vital between controls and individual dose groups RTF, In vitro research have been carried out to evaluate the effects of resorcinol on thyroid function.




  • In in https://www.file-upload.com/vru34908dbiy , resorcinol showed mostly unfavorable results.




  • In both species, there have been no antagonistic results on final mean physique weights, haematology, or medical chemistry parameters, and no chemical-associated gross or microscopic lesions have been observed.




  • Resorcinol is not thought-about to be genotoxic.





There are variations in thyroid physiology between people and animals. The weight of proof means that rodents are more sensitive to thyroid results than people.


According to the outcomes obtained, Daphnia magna is the most delicate organism, and resorcinol may be categorised as acutely toxic only to Daphnia. However, this worth is questionable to be used as a restrict worth in threat evaluation that is the highest focus tested in this study , and the NOEC might be significantly greater than acknowledged within the research. In the environment, resorcinol is rapidly degraded half-life about 2 h by response with photochemically produced hydroxyl radicals. Under ingiunzione di pagamento , resorcinol proved to be readily biodegradable in a check performed according to OECD TG C, and it's more likely to be biodegraded beneath anaerobic situations.

From its use in topical medicine and from restricted data from occupational research, resorcinol does not seem like irritating to the skin in the concentrations reported. Van Leeuwen et al. There is not any indication as as to if the teratogenic results were endocrine mediated or not EC, c. In people, dermal publicity to resorcinol has been reported to be related to thyroid results, CNS disturbances, purple blood cell modifications, and a low incidence of skin sensitization. Five of three.

In in vitro human pores and skin research, resorcinol was evaluated from a consultant hair dye formulation that contained 0. However, it must be considered that acned skin could also be broken due both to scratching or to the blemishes themselves.
