A bitterant is a chemical that is added to a product to make it smell or tastebitter. Bitterants are commonly used as aversive agents to discourage the inhalation or ingestion of toxic substances. Examples of useThe addition of a bitterant to ethanoldenatures the product.Bitterants are used in antifreeze to prevent pet and child poisonings.

DenatoniumDenatoniumDenatonium is an organic ion and one of the bitterest chemical compounds known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharinate. Commercially, it is usually available in salts such as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, Bitrex, Bitrix, Toxishield and Aversion) or as denatonium saccharinate (BITTERANT-s).Aversive agentAversive agents are unpleasantly flavored substances added to poisonous household goods to discourage children and animals from consuming them. Aversive agents are not intended to be harmful, only unpleasant. For example, to prevent children from consuming poisonous anti-freeze, which has a sweet flavor due to the ethylene glycol, an aversive agent is added, which gives the anti-freeze an unpleasant taste.Denatured alcoholDenatured alcoholDenatured alcohol, also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom, and as denatured rectified spirit, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. It is sometimes dyed so that it can be identified visually. Pyridine and methanol, each and together, make denatured alcohol poisonous; denatonium makes it bitter.TasteTasteThe gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste. Taste is the perception stimulated when a substance in the mouthreacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with the sense of smell and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food and other substances.EthanolEthanolOrganic compoundNames Pronunciation Preferred IUPAC nameEthanolOther names Absolute alcoholAlcoholCologne spiritDrinking alcoholEthylic alcoholEthyl alcoholEthyl hydroxideEthylene hydrateEthylolGrain alcoholHydroxyethaneMethylcarbinolIdentifiers CAS Number64-17-53D model (JSmol)Interactive imageAbbreviations EtOH Beilstein Reference1718733 ChEBICHEBI:16236ChEMBLChEMBL545ChemSpider682DrugBankDB00898ECHA InfoCard100.000.526Gmelin Reference787 IUPHAR/BPS2299KEGGC00469PubChemCID702UNII3K9958V90MUN numberUN 1170 CompTox Dashboard(EPA)DTXSID9020584InChIInChI=1S/C2H6O/c1-2-3/h3H,2H2,1H3Key: LFQSCWFLJHTTHZ-UHFFFAOYSA-NInChI=1/C2H6O/c1-2-3/h3H,2H2,1H3Key: LFQSCWFLJHTTHZ-UHFFFAOYABSMILESOCCProperties Chemical formulaC2H6OMolar mass46.069 g·mol Appearance Colorless liquid Odorwine-like, pungent Density0.78945 g/cm (at 20 °C) Melting point−114.14 ± 0.03 °C (−173.45 ± 0.05 °F; 159.01 ± 0.03 K) Boiling point78.23 ± 0.09 °C (172.81 ± 0.16 °F; 351.38 ± 0.09 K) Solubility in waterMisciblelog P−0.31 Vapor pressure5.95 kPa (at 20 °C) Acidity (pKa) 15.9 (H2O), 29.8 (DMSO) Magnetic susceptibility (χ)−33.60·10 cm/mol Refractive index (nD)1.3611 Viscosity1.2 mPa·s (at 20 °C), 1.074 mPa·s (at 25 °C) Dipole moment1.69 D Hazards GHS labelling: PictogramsSignal wordDangerHazard statementsH225, H319, H360DPrecautionary statementsP210, P233, P240, P241, P242, P305+P351+P338NFPA 704 (fire diamond) 230Flash point14 °C (57 °F; 287 K) (Absolute) Lethal dose or concentration (LD, LC): LD50 (median dose)7060 mg/kg (oral, rat)3450 mg/kg (mouse)NIOSH (US health exposure limits): PEL (Permissible)TWA 1000 ppm (1900 mg/m) REL (Recommended)TWA 1000 ppm (1900 mg/m) IDLH (Immediate danger)3300 ppm Safety data sheet (SDS) Related compounds Related compoundsEthaneMethanolSupplementary data page Ethanol (data page)Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).N verify ( ?)Gas dusterGas dusterA gas duster, also known as compressed air or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.AntifreezeAntifreezeAn antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to it.Mustard oilMustard oilMustard oil refers to either the pressed oil of the mustard plant used for cooking or its pungent essential (or volatile) oil. Pressed mustard oil is used as cooking oil in many South Asian cuisines; however, sale is restricted in some North American and European countries due to high levels of erucic acid, though some varieties have lower erucic acid content.TolueneTolueneToluene (), also known as toluol (), is a substituted aromatic hydrocarbon with the chemical formula C6H5CH3, often abbreviated as PhCH3, where Ph stands for the phenyl group. Toluene is a colorless, water-insoluble liquid with a sweet smell, and is partially responsible for the aroma of gasoline and paint fumes. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group by a single bond.InhalantInhalantChemical, often household, breathed in to cause intoxicationMedical conditionInhalants are a broad range of household and industrial chemicals whose volatile vapors or pressurized gases can be concentrated and breathed in via the nose or mouth to produce intoxication, in a manner not intended by the manufacturer.Substance (chemistry)Substance (chemistry)In chemistry, a substance is a unique form of matter with constant chemical composition and characteristic properties. Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. If a mixture is separated to isolate one chemical substance to a desired degree, the resulting substance is said to be chemically pure.ToxicityToxicityToxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity). Sometimes the word is more or less synonymous with poisoning in everyday usage.Impact glueImpact glueImpact glue, contact glue, contact cement, or neoprene glue is a type of solvent-based adhesive which may be used to bond materials such as plastics, laminates, and metal or wood veneers. The term "contact glue" comes from the practice of applying adhesive to both surfaces to be bonded; the surfaces are joined once the solvent in the adhesive evaporates, leaving a bond with high shear resistance.
