SUBACUTE INHALATION TOXICITY OF BENZALDEHYDE IN THE SPRAGUE-DAWLEY RAT. 2. Cinnamaldehyde is a food additive, and the FDA (U.S. Food and Drug Administration) categorizes it under the “generally-recognized as safe” (abbreviated GRAS) grouping of compounds. Benzaldehyde is included on the dangerous goods list. IRIS assessment development process. Benzoic aldehyde; Short-Term Toxicity. Multiple assays and in-vivo studies from the 90's and early 2000s present a HUGELY varied compilation of results regarding inhalation toxicity of benzaldehyde in mice. In contact with strong acids or bases it will undergo an exothermic condensation reaction [Sax, 9th ed., 1996, p. 327]. The International Maritime Dangerous Goods Code lays down basic principles for transporting hazardous chemicals. Toxicity . Repeated inhalation of volatilized Benzaldehyde produced ocular and nasal irritation at 500 ppm and death in rabbits at 750 ppm. BENZALDEHYDE must be blanketed with an inert gas at all times since it is oxidized readily by air to benzoic acid [Kirk-Othmer, 3rd ed., Vol. Benzaldehyde presents naturally in bitter almond oil, patchouli oil, and hyacinth oil. Detailed recommendations for individual substances and a number of recommendations for good practice are included in the classes dealing with such substances. Sigma-Aldrich offers a number of Benzaldehyde products. These data imply that the acute toxicity of benzyl alcohol, which includes sedation, dyspnea, and loss of motor function, is due to the alcohol itself and not to its metabolite, benzaldehyde. The effects of benzaldehyde and reaction products on yeast pyruvate decarboxylase and alcohol dehydrogenase stability were determined. 3, 1978, p. 736]. 52, No. Benzyl alcohol, benzoic acid and its salts (ie, sodium, calcium, magnesium, and potassium benzoate), and benzyl benzoate are reported to function as fragrance ingredients, pesticides, pH adjusters, preservatives, solvents, and/or viscosity decreasing agents in cosmetic products. The lethal dose for a 70 kg adult is considered to be 50 ml. and Culex quinquefasciatus (Say) mosquitoes in laboratory trials to find out the possibilities of using these compounds in mosquito control programmes. Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). 1950 Oct;2(4):471-6.

To view acute toxicity of individual products, click on 'View Products' link in the 'Chemical Identification' section above. Cinnamaldehyde is currently classified as not dangerous or toxic to humans. This site is now being updated and maintained for access by the NIH Office of Dietary Supplements 503-510. Reductions in yeast biomass levels and especially protein and lipid content were observed during the biotransformation. Toxicity data: LD 50 in rats, guinea pigs (mg/kg): 1300, 1000 orally (Jenner) NOTE: Benzaldehyde FFC designates a grade of benzaldehyde free from chlorine. Natural benzaldehyde is typically derived from a cyanogenic glycoside amygdalin found in fruit kernels. Undiluted Benzaldehyde was irritating to … Rev Invest Clin. 3. American Industrial Hygiene Association Journal: Vol. Benzoic acid is metabolised to either benzoyl glucuronide or hippuric acid. Human health assessment information on a chemical substance is included in the IRIS database only after a comprehensive review of toxicity data, as outlined in the . Cancer Information: 2,4-D IARC Carcinogens U.S. NTP Carcinogens Section 13 - Disposal Considerations Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. Articles of Benzaldehyde are included as well. Testing Status of Benzaldehyde 10087-A . 1. Chemsrc provides Benzaldehyde(CAS#:100-52-7) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Developmental toxicity studies, subacute, subchronic, chronic studies and 4-generation study performed with the benzoate group substances (benzyl acetate, benzyl alcohol, benzaldehyde and sodium benzoate) indicate that these compounds are not reprotoxic or developmental toxicants. 1.Benzoic acid - toxicity 2.Sodium benzoate - toxicity 3.Risk assessment 4.Environmental exposure I.International Programme on Chemical Safety II.Series ISBN 92 4 153026 X (NLM Classification: QD 341.A2) ISSN 1020-6167 The World Health Organization welcomes requests for permission to reproduce or translate its publications, in part or in full. [Toxicity of p-amino-benzaldehyde-thiosemicarbazone (TBI)]. Benzaldehyde poisoning: Benzaldehyde poisoning is listed as a type of (or associated with) the following medical conditions in our database: Poisoning, overdose, toxicity or adverse reactions Chemical-related conditions 2 … Paulraj, A.D. Reegan and S. Ignacimuthu: Abstract: The larvicidal, pupicidal and knockdown effects of benzaldehyde, propionic acid and their blend (1:1 ratio) were evaluated against Aedes aegypti (Linn.) Subacute inhalation toxicity of benzaldehyde in the Sprague-Dawley rat. CAUTION: Narcotic in high concns. (1991). It appears colorless liquid with a characteristic almond-like odor. EBSCOhost serves thousands of libraries with premium essays, articles and other content including Toxicity of Benzaldehyde and Propionic Acid against Immature and Adult Stages of Aedes aegypti (Linn.) Benzaldehyde does not accumulate in any tissues, and is metabolized and then excreted in urine. Benzaldehyde; CASRN 100-52-7. Benzaldehyde is also known chemically as a benzene carbaldehyde, or phenylmethanal, or benzoic aldehyde. Benzaldehyde appeared to alter the cell permeability barrier to substrates and products. Among important volatiles is the alcohol 3-methylbutanol, which is considered a key odorant in ‘Grenache’, ‘Cabernet Sauvignon’, and ‘Merlot’ wines ( Kotseridis and Baumes, 2000 ). The acute toxicity reported on this page is of the pure chemical ingredient only and may not reflect the acute toxicity of individual pesticide products. Get access to over 12 million other articles! In a 16-week feeding study, rats given up to 10,000 ppm showed no signs of toxicity. Toxicity of Benzaldehyde and Propionic Acid against Immature and Adult Stages of Aedes aegypti (Linn.) Benzaldehyde is the majority constituent of almond flavoring and present in many nut-based ingredients. Benzaldehyde has low toxicity, though it may be irritant. However, the toxicity of hydrocyanic acid as by-product presents a safety problem. CASRN: 100-52-7 Formula: C7-H6-O Synonyms/Common Names. Benzaldehyde is in turn metabolised to benzoic acid, primarily by mitochondrial aldehyde dehydrogenase-2 (ALDH-2), while only a small percentage is metabolised by cytosolic ALDH-1. [Article in Undetermined Language] PARDO EG, GARCIA TELLEZ D. PubMed:Synthesis and properties of 5,10,15,20-tetrakis[4-(alkoxysilyl)phenyl]porphyrins: an application of selective deprotection of benzaldehyde diethyl acetals in the presence of alkoxysilyl groups. and Culex quinquefasciatus (Say) (Diptera: Culicidae). Some studies indicate that benzaldehyde might have anti-cancer properties. There are three methods to synthesize benzaldehyde: toluene oxidation, catalytic dehydrogenation of benzyl alcohol, and hydrolysis of dichlorobenzyl methane. To use an extreme example of toxicity, natural Bitter Almond oil contains about 3% hydrocyanic acid (cyanide), and if you drink an ounce of the oil it will kill you – the 97% of benzaldehyde has no protective effect. Benzaldehyde and benzoic acid, which may constitute a precursor of volatile benzenoids, showed a tendency to decrease in all varieties during ripening. The larvicidal, pupicidal and knockdown effects of benzaldehyde, propionic acid and their blend (1:1 ratio) were evaluated against Aedes aegypti (Linn.) Inhalation presents known risks. Although pretreatment with disulfiram led to benzaldehyde levels which were 368% of control values, toxicity was unchanged. (You could not actually drink unrectified Bitter Almond oil – it has been banned for the last 150 years because of its toxicity.) Reactions Edit Benzaldehyde can be oxidized to benzoic acid ; in fact "[B]enzaldehyde readily undergoes autoxidation to form benzoic acid on exposure to air at room temperature" causing a common impurity in laboratory samples. Sections I (Health Hazard Assessments for … Other: Benzaldehyde absorbs UV irradiation weakly (extinction coefficient of 0-30/M-cu cm) in the spectra between 300 and 380 nm.
