Resorcinol is known to type 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 variations within the susceptibility to goitrogens.


The organisms were uncovered to the take a look at concentrations for 96 h. Biological observations were carried out daily.


Animals have been maintained for a number of months with periodic sacrifices Flickinger, The animals have been then examined weekly for 10 further weeks. Sacrificed animals confirmed brown-dyed abdomen walls and filling of stomach and small gut with a darkish-brown to orange substance. These findings weren't noted in survivors.
A concentration of zero. These substances had been discovered to be potent inhibitors of thyroid peroxidase or I organification. Resorcinol in addition to 2- and 5-methylresorcinol were reported to be At an iodide focus of 0.





  • No other biologically significant differences in organ weights were observed.




  • https://sendit.cloud/ou942kqcqtgy -day absorption assuming cm 2 of scalp was given as 0.




  • Resorcinol appears to be absorbed much better from anti-zits preparations than from the hair dye preparations underneath regular usage circumstances.




  • In rodents, the higher sensitivity can be associated to a shorter plasma half-lifetime of T 4 than in people due to appreciable variations between species in the transport proteins for thyroid hormones.




  • The microscopic examination of the thyroid gave minimal modifications follicular hyperplasia , which have been statistically not vital between controls and particular person dose teams RTF, In vitro research have been performed to assess the consequences of resorcinol on thyroid function.







In apply, nevertheless, the incidence of sensitization appears to be low. In animal studies, the toxicological effects reported to be brought on by administration of resorcinol embody thyroid dysfunction, irritation to pores and skin and eyes, CNS results, and altered adrenal gland relative weights. After topical use of excessive concentrations of resorcinol, CNS disturbances, similar to dizziness, vertigo, confusion, disorientation, amnesia, or tremors, or purple blood cell adjustments, corresponding to methaemoglobinaemia, haemolytic anaemia, haemoglubinuria, or cyanosis, have been reported. One factor growing potential poisonous effects is the applying of resorcinol to injured pores and skin.
In one other study, male F rats have been handled with three intraperitoneal injections of 3-methyl-. Based on the study of Yeung et al.
Apart from one positive single case-examine Vilaplana et al. In these cases, the examined concentration of resorcinol was zero. The knowledge are summarized in Table eight. Data concerning the totally different job classes were not offered.
