Thyroid glands from all surviving F 0 mother and father were examined microscopically, and mind measurements were performed on all exposed F 1 pups and people F 1 pups chosen for behavioural testing. There had been no important intercourse differences. In females, a higher proportion was excreted as sulfate conjugate, whereas males excreted a better proportion of a diconjugate both sulfate and glucuronide groups. From these information, the authors concluded that male rats have a better capacity for glucuronidation than females.
The organisms had been exposed to the test concentrations for ninety six h. Biological observations were performed daily.
For the benthic and terrestrial compartments, the obtainable toxicity data can't be thought to be enough for a quantitative threat characterization. However, these compartments are much less related for resorcinol, due to marginal releases and emissions to those compartments as well as a very low potential for adsorption of resorcinol to organic matter.
In general, the h LC 50 values for resorcinol had been in the range between In move-by way of tests and analytical monitoring, DeGraeve et al. As mentioned in part 9. Complete therapeutic was noted after about 1 week of absence from work. However, with increasing resorcinol concentrations, there was also a rise in the number of individuals who tested constructive. Resorcinol was additionally examined in hairdressers, who might have been in touch with resorcinol-containing hair dyes.

One issue increasing potential poisonous results is the applying of resorcinol to injured skin Cassano et al. Surviving F zero parental and F 1 following selection rats underwent complete gross necropsy following the breeding period seven F zero males per group , following completion of weaning of F 1 pups F zero 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.
In practice, however, the incidence of sensitization seems to be low. In animal research, the toxicological results reported to be caused by administration of resorcinol embody thyroid dysfunction, irritation to pores and skin and eyes, CNS effects, and altered adrenal gland relative weights. After topical use of excessive concentrations of resorcinol, CNS disturbances, corresponding to dizziness, vertigo, confusion, disorientation, amnesia, or tremors, or purple blood cell changes, corresponding to methaemoglobinaemia, haemolytic anaemia, haemoglubinuria, or cyanosis, have been reported. One issue increasing potential poisonous effects is the appliance of resorcinol to injured skin.
The elimination was biphasic, with half-lives of 18—21 min and eight. The 14 C activity was quickly distributed in main tissues corresponding to muscles, kidneys, and liver, without indication of bioaccumulation Merker et al. Any new information being offered in the middle of the OECD evaluation will be provided to the IPCS in order that an addendum could be ready for consideration.

In both species, there have been no adverse effects on ultimate imply body weights, haematology, or scientific chemistry parameters, and no chemical-associated gross or microscopic lesions were noticed. In one other study, rats had been uncovered to zero or zero. No thyroid hormone measurements were carried out.
Two lengthy-term research with Swiss mice or NZW rabbits, where the animals were handled with zero. In an in vitro. In an investigation in three human volunteers using conditions just like these utilized in hair dyeing, 14 C-ring-labelled 1. This means that solely a small quantity of resorcinol penetrates the pores and skin during the precise strategy of hair colouring.
British Journal of Industrial Medicine , Toxicologic Pathology , Toxicology and Applied Pharmacology , Arnott DG, Doniach I The effect of compounds allied to resorcinol upon the uptake of radioactive iodine I by the thyroid of the rat. IARC evaluated the carcinogenicity of resorcinol in and concluded that there are not any epidemiological knowledge relevant to the carcinogenicity of resorcinol in people and that the evidence of its carcinogenicity in animals is insufficient; thus, resorcinol isn't classifiable as to its carcinogenicity to humans. JECFA assessed the hazards from the use of resorcinol as a food flavouring agent and concluded that this use is of no safety concern. Overall, the studies usually are not adequate for a statistical extrapolation approach in accordance with the EU Technical Guidance Document EC, a.

Animals were maintained for several months with periodic sacrifices Flickinger, The animals were then examined weekly for 10 further weeks. Sacrificed animals showed brown-dyed stomach partitions and filling of stomach and small intestine with a dark-brown to orange substance. These findings were not noted in survivors.

In rodents, the higher sensitivity is also related to a shorter plasma half-life of T four than in people as a result of considerable variations between species in the transport proteins for thyroid hormones. In plasma, the T four half-life is about 12—24 h in rats vs 5—9 days in people, and the serum levels of TSH are about 25 times larger in rodents than in people.
In in vitro genotoxicity checks, resorcinol confirmed principally adverse results. Results from all reported in vivo exams for genotoxicity had been adverse. Mostly unfavorable results have been reported in the initiation—promotion studies performed using several species. UV irradiation triggered no increased pores and skin reactions. The iodination course of is catalysed by a haem-containing enzyme.

In in vitro human skin studies, resorcinol was evaluated from a consultant hair dye formulation that contained 0. However, it must be thought of that acned skin may be broken due both to scratching or to the blemishes themselves.
