Butylated Hydroxytoluene or BHT is a stabiliser that can be found in cosmetic products.
It acts as an antioxidant that helps maintain the properties and performance of a product as it is exposed to air (to avoid a change in odor, in color, in texture...).
Butylated hydroxytoluene (BHT) is commonly used in cosmetic formulations as an antioxidant.
In addition to personal care products and makeup, it is also widely used in plastics and foods.
BHT (or 2,6-di-tert-butyl-p-cresol) is a white to yellowish crystalline solid that prevents the oxidation of fats and oils, and helps to extend a product's shelf-life.
Butylated Hydroxytoluene is produced by the reaction of p-cresol with isobutylene and sulfuric acid.
The key function of BHT is that of a stabilizer.
Butylated Hydroxytoluene inhibits the degradation of fats and oils through its antioxidant action and prevents rancidity.
BHT is also a food additive, which is approved by the Food and Drug Administration, and is generally recognized as safe (GRAS).
In cosmetic formulations, BHT is often used at concentrations ranging from 0.0001% to 0.5%

BHT is used in various cosmetic products, including certain formulas containing fats or in aqueous emulsions containing certain active ingredients or plant extracts.
BHT is an antioxidant used in certain products to stabilise and protect the raw materials themselves, and less as an ingredient in and of itself.
BHT can resist high temperatures (unlike some natural antioxidants): it is therefore very useful in certain raw material manufacturing processes.
BHT as an ingredient for its antioxidant properties, helping to protect the products of oxidation and ensure the quality and stability of formulas.
BHT is an antioxidant that prevents the oxidation of products, and in particular the fatty phase of formulas that are likely to rancor or degrade when in contact with the air.
Oxydation is a chemical reaction through which a componant of the formula react with the oxygen.
It enables to maintain the properties and performance of a product when exposed to air.
BHT should be used at an optimal and regulated concentration level: 0.1% in leave-on products and 0.5% in rinse-off products.
BHT was first used as an antioxidant food additive in 1954.
An antioxidant is a substance that prevents the oxidation of materials with which it occurs.
BHT, therefore, prevents the spoilage of food to which it is added.
BHT has grown to be very popular among food processors and is now used in a great range of products that include breakfast cereals, chewing gum, dried potato flakes, enriched rice, potato chips, candy, sausages, freeze-dried meats, and other foods containing fats and oils.
BHT is sometimes used in conjunction with a related compound, butylated hydroxyanisole (BHA) as a food additive.

Some evidence exists that BHT may be harmful to human health.
Studies suggest that the compound may damage the liver and kidneys.
However, the U.S. Food and Drug Administration has deemed that BHT is safe enough when used in limited concentrations.
It currently permits its use in concentrations of about 0.01% to 0.02% in most foods.
As an emulsion stabilizer in shortening, it may be used in a somewhat higher concentration, 200 parts per million.
Some authorities suggest that BHT poses too large a health risk and that it should be banned in foods.
That policy has been adopted in some other nations, such as England and Australia, where its use is permitted as a food additive only in special cases.
BHT does have other commercial uses, as in animal feeds and in the manufacture of synthetic rubber and plastics, where it also acts as an antioxidant.

Butylated hydroxytoluene (BHT) is widely used as a food preservative for its antioxidizing property.
This small, hydrophobic molecule has been found to be a potent inactivator of lipid-containing mammalian and bacterial viruses.
Consumers seek safe, natural ingredients for skin, hair, body, and food products.
Nowadays, more consumers read and research the information found on packaging labels including ingredient listings.
There has been increased concern and caution amongst consumers with the use of synthetic additives in foods and cosmetics.
BHT has been questioned for safety and efficacy due to consumers' skepticism of additives of synthetic origin.
Based on toxicological studies it was concluded that BHT may produce toxicity in high oral doses and can cause adverse effects in some organs using animal models.
Although there are some concerns about BHT, scientific research maintains that when used at low concentrations BHT is safe.
Long-term use studies have substantiated the overall safety and efficacy of BHT.
In skin permeation studies, it was demonstrated that BHT has the ability to penetrate the skin; however, the amount absorbed does not appear to pass through the top layer of the skin, and it has been determined to be safe for use in cosmetics.
Although BHT is still widely used, some companies are searching for alternatives with good toxicological and ecological profiles.
Some possible alternatives are BHT analogues that offer strong stabilizer benefits, such as tocopherols and synthetic analogues.
Another option is to promote BHT as a naturally sourced antioxidant.

Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties.
BHT is widely used to prevent free radical-mediated oxidation in fluids (e.g. fuels, oils) and other materials, and the regulations overseen by the U.S. F.D.A.—which considers BHT
to be "generally recognized as safe"—allow small amounts to be added to foods.
Despite this, and the earlier determination by the National Cancer Institute that BHT was noncarcinogenic in an animal model, societal concerns over its broad use have been expressed. BHT has also been postulated as an antiviral drug, but as of March 2020, use of BHT as a drug is not
supported by the scientific literature and it has not been approved by any drug regulatory agency for use as an antiviral.
Application : Antioxidant BHT has high antioxidant properties, effectively improving the stability of oils, preventing sludge formation. In addition to its use in motor and industrial oils,
the BHT antioxidant finds its application in the production of fluids for metalworking, cosmetics, pharmaceuticals, embalming fluids, antifreeze, antifreeze and auto chemistry. In the
petroleum industry, where BHT is known as a fuel additive, it is used in hydraulic fluids, turbine and transmission oils, and jet fuels.
BHT is listed under several categories in catalogues and databases, such as food additive, household product ingredient, industrial additive, personal care product/cosmetic ingredient,
pesticide ingredient, plastic/rubber ingredient and medical/veterinary/research.
BHT is primarily used as an antioxidant food additive.In the United States, it is classified as generally recognized as safe (GRAS) based on a National Cancer Institute study from
1979 in rats and mice. It is approved for use in the U.S. by the Food and Drug Administration: For example, 21 CFR § 137.350(a)(4) allows BHT up to 0.0033% by weight in "enriched rice",
while 9 CFR § 381.147](f)(1) allows up to 0.01% in poultry "by fat content". It is permitted in the European Union under E321.
BHT is used as a preservative ingredient in some foods. With this usage BHT maintains freshness or prevents spoilage; it may be used to decrease the rate at which the texture, color,
or flavor of food changes.
Some food companies have voluntarily eliminated BHT from their products or have announced that they were going to phase it out.
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. BHT is also used to prevent peroxide formation in organic
ethers and other solvents and laboratory chemicals. It is added to certain monomers as a polymerisation inhibitor to facilitate their safe storage. Some additive products contain
BHT as their primary ingredient, while others contain the chemical merely as a component of their formulation, sometimes alongside butylated hydroxyanisole (BHA).
Like many closely related phenol antioxidants, BHT has low acute toxicity (e.g., the desmethyl analog of BHT, 2,6-di-tert-butylphenol, has an LD50 of >9 g/kg).The US Food and Drug
Administration classifies BHT as generally recognized as safe (GRAS) as a food preservative when used according in an approved manner. In 1979, the National Cancer Institute determined
that BHT was noncarcinogenic in a mouse model.
Based on various, disparate primary research reports, BHT has been suggested to have anti-viral activity, and the reports divide into various study types. First, there are studies that
describe virus inactivation—where treatment with the chemical results in disrupted or otherwise inactivated virus particles. The action of BHT in
these is akin to the action of many other organic compounds, e.g., quaternary ammonium compounds, phenolics, and detergents, which disrupt viruses by insertion of the chemical into
the virus membrane, coat, or other structure,which are established methods of viral disinfection secondary to methods of chemical oxidation and UV irradiation. In addition,
there is a report of BHT use, topically against genital herpes lesions, a report of inhibitory activity in vitro against pseudorabies (in cell culture),
and two studies, in veterinary contexts, of use of BHT to attempt to protect against virus exposure (pseudorabies in mouse and swine, and Newcastle in chickens). The relevance of other
reports, regarding influenza in mice, is not easily discerned.Notably, this series of primary research reports does not support a general conclusion of independent confirmation of the
original research results, nor are there critical reviews appearing thereafter, in secondary sources, for the various host-virus systems studied with BHT.
Hence, at present, the results do not present a scientific consensus in favour of the conclusion of the general antiviral potential of BHT when dosed in humans. Moreover, as of March
2020, no guidance from any of the internationally recognized associations of infectious disease specialists had advocated use of BHT products as an antiviral therapy or prophylactic
