The third study, performed in , included of energetic staff. In topics males, 13 girls with a mean age of 37 years, each laboratory and different tests, together with medical examination, have been done; no abnormal thyroid glands or changes in T 4 values had been found in any of the subjects when compared with normal values Bauer, The above knowledge are limited due to small research sizes, lack of comparability groups, lacking present and historical management data, and missing info concerning potential publicity classes. In a examine in a plant producing resorcinol by sulfonation of benzene — and likewise producing beta -resorcylic acid, resorcinol—formaldehyde resins, sulfites, and sulfates — employees have been uncovered primarily to resorcinol, however the publicity to different agents was not measured for publicity levels, see part 6. In this plant, three cross-sectional studies had been carried out between and Flickinger, In , medical examinations, chest X-rays, pulmonary perform, haematology, and medical chemistry had been carried out with of individuals actively employed at a production plant in Pennsylvania, USA. In addition, male rats have higher circulating ranges of TSH than females.

Complete recovery in all animals occurred inside 1—1. Of the following studies, the repeated-dose toxicity research that were deemed to be most relevant to the risk evaluation are summarized in Appendix 6. In a study carried out by NTP , five female and male F rats were dosed with resorcinol in deionized water via gavage at zero, High-dose females had significantly decreased absolute and relative thymus weights. No different biologically important variations in organ weights have been noticed. In distinction to those findings, Eastin et al.
Fifty per cent of survivors have been sacrificed 1 week later, and blood and urine samples had been taken. Resorcinol confirmed a focus-dependent enhance in labelling index [ 3 H]thymidine , acanthosis, and papillomatosis. After application of an ointment containing To examine the goitrogenic activity of resorcinol, female Wistar rats had been handled twice daily for 28 days by rubbing 6 g of an ointment containing Increased thyroid gland weights 2.
In , medical examinations see above and thyroid assessments were carried out with of presumably energetic plant staff men and 33 women. Flaked resorcinol triggered no perceptible to moderate irritation intact skin or no perceptible necrosis abraded skin.
More traditional-use conditions would result in exposures of about 0. Further details weren't given.

A concentration of 0. These substances had been found to be potent inhibitors of thyroid peroxidase or I organification. Resorcinol in addition to 2- and 5-methylresorcinol had been reported to be At an iodide concentration of zero.

• In a report based on consumer analysis data Gans, , beneath cheap maximum-use conditions i.





• In people, dermal publicity to resorcinol has been reported to be related to thyroid results, CNS disturbances, pink blood cell changes, and a low incidence of pores and skin sensitization.





• More ordinary-use situations would end in exposures of about 0.





• In an in vitro.





• Furthermore, Cronin et al.





• Overall, the research aren't adequate for a statistical extrapolation technique in accordance with the EU Technical Guidance Document EC, a.





• Female Syrian golden hamsters 10—20 per group have been handled with two subcutaneous injections of.





• Biological observations have been performed day by day.





• JECFA assessed the hazards from using resorcinol as a meals flavouring agent and concluded that this use is of no security concern.

In practice, nevertheless, the incidence of sensitization seems to be low. In animal studies, the toxicological effects reported to be attributable to 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 high 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 increasing potential poisonous effects is the appliance of resorcinol to injured pores and skin.
In basic, the h LC 50 values for resorcinol have been in the vary between In move-via tests and analytical monitoring, DeGraeve et al. As talked about in part 9. Complete healing was noted after about 1 week of absence from work. However, with growing resorcinol concentrations, there was additionally a rise in the variety of individuals who examined optimistic. Resorcinol was also examined in hairdressers, who might have been in contact with resorcinol-containing hair dyes.
Experimental knowledge on soil sorption utilizing silty loam point out a really low potential for geoaccumulation. However, the uncovered space cm 2 was tremendously in extra of the common space of skin often handled for acne. Formulations tested in the important thing studies anti-pimples cream and hair dye have in all probability modified during the last 20 or more years. Resorcinol enters the surroundings primarily during its usage in shopper merchandise hair dyes and prescription drugs. In addition, localized high concentrations can appear in coal conversion wastewater or in wastewater in regions with oil shale mining.

Animals that died confirmed hyperaemia and distension of stomach and intestine, whereas there were no gross lesions at necropsy in survivors Flickinger, In one other examine with CFY rats. Most of the research are of sufficient high quality and acceptable for threat characterization functions.

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-reports in humans. However, there are species variations within the susceptibility to goitrogens.
In in vitro genotoxicity exams, resorcinol showed mostly unfavorable results. Results from all reported in vivo exams for genotoxicity have been unfavorable. Mostly adverse results have been reported within the initiation—promotion research carried out utilizing several species. UV irradiation triggered no elevated pores and skin reactions. The iodination course of is catalysed by a haem-containing enzyme.
The tolerable intake of zero. It is therefore possible that these neurological effects are because of the acute effect of the gavage administration. CNS results in people and animals have been related to acute exposure to resorcinol.
