What is the function of BHT?
BHT (butylated hydroxytoluene) is a lab-made chemical that is added to foods as a preservative. People also use it as medicine. BHT is used to treat genital herpes and acquired immunodeficiency syndrome (AIDS). Some people apply BHT directly to the skin for cold sores.
What is BHT test?
Testing for the presence of BHA/BHT in cosmetic and food products is typically conducted employing a chromatographic technique, primarily Gas Chromatography (GC). However, High Performance Liquid Chromatography (HPLC) and Ultra Performance Liquid Chromatography (UPLC) may also be suitable.
What is dibutyl hydroxy toluene?
Description. Butylated Hydroxytoluene is an organic chemical composed of 4-methylphenol modified with tert-butyl groups at positions 2 and 6. Butylated hydroxytoluene (BHT) inhibits autoxidation of unsaturated organic compounds.
What is BHT form?
Abbreviation for butylated hydroxytoluene.
How much BHT is safe?
The Food and Drug Administrationconsiders it “generally recognized to be safe”or GRAS, the government’sstandardfor safety as a food additive and preservative. It’s beenapproved for use in various foodsup to0.02 percent or 200 parts per million of the fat or oil contentof the food productwith a couple exceptions.
What are the side effects of BHA?
Side effects
- burning sensation on the skin.
- rash.
- swelling.
- changes in skin color.
- blisters or welts.
- skin peeling.
- itching.
- skin irritation.
How bad is BHT?
There is no scientific evidence that BHT is harmful in the amounts used in packaged food. Indeed, in small amounts, it may have anticancer effects similar to those provided by naturally occurring antioxidants.
What is beta hydroxy acid used for?
While both AHAs and BHAs act as exfoliants, it has been claimed that BHAs are effective in reducing the appearance of fine lines and wrinkles, and improving overall skin texture, without the occasional irritation associated with the use of AHAs. Currently, the BHA most commonly used in cosmetics is salicylic acid.
What is BHT used for in everyday life?
BHT is also used as an antioxidant in products such as metalworking fluids, cosmetics, pharmaceuticals, rubber, transformer oils, and embalming fluid. In the petroleum industry, where BHT is known as the fuel additive AO-29, it is used in hydraulic fluids, turbine and gear oils, and jet fuels.
What is the chemical name of BHT in locomotive?
For the Italian electric locomotive, see FS Class E.321. Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties.
How does BHT stop an autocatalytic reaction?
BHT stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides. It effects this function by donating a hydrogen atom: where R is alkyl or aryl, and where ArOH is BHT or related phenolic antioxidants. Each BHT consumes two peroxy radicals.
What is butylated hydroxytoluene (BHT)?
Butylated hydroxytoluene ( BHT ), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties.
