Determination of resorcinol conjugates in the h urine samples after 14 days of continuous product therapy confirmed that a maximal 23 mg 2. Assuming a body weight of 64 kg IPCS, provides an publicity estimate of 0. In a report based on client research information Gans, , underneath reasonable most-use situations i.

Resorcinol is understood to type covalent bonds with haem Sessler et al. Effects on the thyroid gland have been reported each in animal studies and in case-stories in people. However, there are Matassa U/UTP Cavo Cat.5E CCA 305m Rigido Grigio in the susceptibility to goitrogens.
The bulk of the urine-recovered dye should have been taken up into the sexy layer of the pores and 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 have been performed with of presumably energetic plant staff males and 33 girls. Flaked resorcinol caused no perceptible to reasonable irritation intact pores and skin or no perceptible necrosis abraded skin.





  • In addition, male rats have greater circulating ranges of TSH than females.




  • Of the following studies, the repeated-dose toxicity research that have been deemed to be most relevant to the danger 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 treated pores and skin areas showed slight erythema and extreme dryness.




  • In the frame of a full life cycle toxicity take a look at OECD TG , Lima noticed no opposed results after forty eight h of publicity on the highest concentration examined, 0.




  • Astagiudiziaria of the thyroid gave minimal modifications follicular hyperplasia , which have been statistically not vital between controls and individual dose groups RTF, In vitro research have been carried out to evaluate the consequences of resorcinol on thyroid function.




  • In in vitro genotoxicity tests, resorcinol confirmed mostly unfavorable results.




  • In both species, there were no opposed results on final imply body weights, haematology, or medical chemistry parameters, and no chemical-related gross or microscopic lesions were observed.





There are variations in thyroid physiology between people and animals. The weight of evidence means that rodents are more delicate to thyroid effects than people.


According to the outcomes obtained, Daphnia magna is probably the most delicate organism, and resorcinol could be categorized as acutely poisonous only to Daphnia. However, this value is questionable for use as a restrict value in threat assessment this is the highest focus tested on this examine , and the NOEC could be significantly greater than said within the study. In the environment, resorcinol is rapidly degraded half-life about 2 h by response with photochemically produced hydroxyl radicals. Under cardio circumstances, resorcinol proved to be readily biodegradable in a test performed based on OECD TG C, and it is likely to be biodegraded under anaerobic conditions.

From its use in topical medication and from limited data from occupational research, resorcinol does not appear to be irritating to the pores and skin within the concentrations reported. Van Leeuwen et al. There isn't any indication as to whether the teratogenic results had been endocrine mediated or not EC, c. In humans, dermal exposure to resorcinol has been reported to be associated with thyroid results, CNS disturbances, red blood cell changes, and a low incidence of pores and skin sensitization. Ricerca aste immobiliari of three.


In in vitro human pores and skin research, resorcinol was evaluated from a representative hair dye formulation that contained 0. However, it ought to be thought-about that acned skin may be damaged due either to scratching or to the blemishes themselves.
