The compound contributes to Guaiacol - Toxicity Data: Oral LDLO (human): 43 mg/kg; Oral LD50 (rat): 520 mg/kg; Subcutaneous LDLO (rat): 900 mg/kg; Oral LD50 (mouse): 621 mg/kg; Information on Toxicological Effects: Guaiacol - Investigated as a mutagen and primary irritant. Only select Registry of Toxic Effects of Chemical Substances (RTECS) data is presented here. Guaiacol is harmful by ingestion (classified acute. Tox. Cat.4, H302) based on the LD50 of 725 mg/kg bw/day identified in both sex and according to the EU classification criteria (Annex VI of Directive 67/548/EEC and Annex I of Regulation (EC) n°1272/2208). Guaiacol was officially classified in the Regulation (EC) n°1272/2008 Annex VI table 3 and was not classified for acute toxicity by inhalation. Information on Registered Substances comes from registration dossiers which have been assigned a registration number. At a concentration higher than 3 mM, eugenol was cytotoxic to human oral mucous membrane cells, decreasing both cellular ATP and glutathione.

Vol. 45(10), Pg. 16, 1980. intraperitoneal-mouse LD50 320 mg/kg The increased concentration of H 2 O 2 in the leaf apoplast caused by Mn toxicity is accompanied by a guaiacol-POD-catalysed oxidation of monophenols and also probably the co-oxidation of Mn II (demonstrated by Kenten and Mann, 1950), resulting in enhanced evolution of phenoxy radicals and Mn III intermediates, which might also be responsible for the leaf browning (Horst, 1988). 9 Mar 2015 It is shown that only after the primary pollutant guaiacol has been consumed, its probably most toxic nitroaromatic product is largely formed. Of the compounds developed in this study the most effective were: Tetrabrom-o- cresol, which has but little toxicity yet inhibits growth of diph- theria bacilli diluted to The enzymes guaiacol peroxidase (GPX) and catalase (CAT) activities increased in both the plants and were higher in V. faba. A positive correlation between 13 May 2020 Lead toxicity resulted in increased level of the guaiacol peroxidase activity in both cultivars.

Disposition of Toxic Drugs and Chemicals in Man. Acute toxicity of guaiacol administered subcutaneously in the mouse. Guaiacol is a compound used as expectorant. In Mexico City, this product is being illegally used for aesthetic treatment with fatal results. The aim of this study is to confirm the lethal toxicity documented in humans. Guaiacol is a precursor to various flavorants, such as eugenol. An estimated 85% of the world's supply of vanillin comes from guaiacol.
