Aversive Agent
Aversive 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. There are two primary classes of aversive agents: bitterants, chemicals producing a bitter flavor, and pungent agents, chemicals producing an unpleasantly pungent flavor.

Household Goods
Household goods are good (economics), goods and product (business), products used within households. They are the tangible property, tangible and movable personal property placed in the rooms of a house, such as a bed or refrigerator. Economic role Businesses that produce household goods are categorized as Procyclical, Cyclical Consumer Products by the Thomson Reuters Business Classification and are organized into three sub-categories: *Consumer electronics, Consumer Electronics, *Home appliance, Appliances, tools and housewares *Home Furnishings (such as furniture) Household goods are a significant part of a country's economy, with their purchase the topic of magazines such as ''Consumer Reports'', their relocation handled by Moving company, moving companies, and their disposal or redistribution facilitated by companies like Goodwill Industries, services like classified advertising and Craigslist, and events such as garage sales and car boot sales. Their safety is often regulate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-freeze
An 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. Because water has good properties as a coolant, water plus antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. The purpose of antifreeze is to prevent a rigid enclosure from bursting due to expansion when water freezes. Commercially, both the ''additive'' (pure concentrate) and the ''mixture'' (diluted solution) are called antifreeze, depending on the context. Careful selection of an antifreeze can enable a wide temperature range in which the mixture remains in the liquid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylene Glycol
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol) with the formula . It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, flammable, viscous liquid. Ethylene glycol has a sweet taste, but it is toxic in high concentrations. Production Industrial routes Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation: This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water. Under these conditions, ethylene glycol yields of 90% can be achieved. The major byproducts are the oligomers diethylene glycol, triethylene glycol, and tetraethylene glycol. The separation of th ...

Bitterant
A bitterant (or bittering agent) is a chemical that is added to a product to make it smell or taste bitter. Bitterants are commonly used as aversive agents to discourage the inhalation or ingestion of toxic substances. Examples of use *The addition of a bitterant to ethanol denatures the product. *Bitterants are used in antifreeze to prevent pet and child poisonings. It is required by law in some places (France, Oregon, etc.). *Gas dusters often use a bitterant to discourage inhalant abuse, although this can cause problems for legitimate users. The bitterant not only leaves a bitter flavor in the air, but also leaves a bitter residue on objects, like screens and keyboards, that may transfer to hands and cause problems (such as when eating). *Game cartridges for the Nintendo Switch are coated with denatonium as a safety feature to deter small children from ingesting them. *Some button cell batteries manufactured by Duracell are coated with a bitterant to discourage accidental in ...

Denaturation (food)
The word denature means to render food unpleasant or dangerous to consume, it is denatured by adding a substance known as a denaturant. Aversive agents—primarily bitterants and pungent agents—are used to produce an unpleasant flavor. For example, the bitterant denatonium might be added to food used in a laboratory, where such food is not intended for human consumption. A poisonous substance may be added as an even more powerful deterrent. For example, methanol is blended with ethanol to produce denatured alcohol. The addition of methanol, which is poisonous, renders denatured alcohol unfit for consumption, as ingesting denatured alcohol may result in serious injury or death. Thus denatured alcohol is not subject to the taxes usually levied on the production and sale of alcoholic beverages. Aniline was used to denature colza oil in the 1980s.{{cn, date=September 2021 See also *Denaturation (biochemistry) In biochemistry, denaturation is a process in which proteins or ...

Adulterant
An adulterant is caused by the act of adulteration, a practice of secretly mixing a substance with another. Typical substances that are adulterated include but are not limited to food, cosmetics, pharmaceuticals, fuel, or other chemicals, that compromise the safety or effectiveness of the said substance. It will not normally be present in any specification or declared substances due to accident or negligence rather than intent, and also for the introduction of unwanted substances after the product has been made. Adulteration, therefore, implies that the adulterant was introduced deliberately in the initial manufacturing process, or sometimes that it was present in the raw materials and should have been removed, but was not. An adulterant is distinct from, for example, permitted food preservatives. There can be a fine line between adulterant and additive; chicory may be added to coffee to reduce the cost or achieve a desired flavor—this is adulteration if not declared, but m ...

Denatonium
Denatonium, usually available as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, ''Bitrex'', and ''Aversion'') and as denatonium saccharide (BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. It was discovered in 1958 during research on local anesthetics by MacFarlan Smith of Edinburgh, Scotland, and registered under the trademark ''Bitrex''. Dilutions of as little as 10 ppm are unbearably bitter to most humans. Denatonium salts are usually colorless and odorless solids but are often traded as solutions. They are used as aversive agents (bitterants) to prevent inappropriate ingestion. Denatonium is used in denatured alcohol, antifreeze, preventive nail biting preparations, respirator mask fit-testing, animal repellents, liquid soaps, shampoos, and Nintendo Switch game cards to prevent accidental swallowing or choking by children.
