BHA

What Is It?

Butylated Hydroxyanisole, known as BHA, is a waxy solid that can be found in a variety of cosmetics and personal care products, particularly in lipstick and eye shadow. Butylated Hydroxyanisole should not be confused with a class of cosmetic ingredients, Beta Hydroxy Acids, which may also be abbreviated BHA.

Why Is It Used?

BHA functions as an antioxidant.

Scientific Facts

Due to its antioxidant properties, BHA is used in cosmetic and personal care products, as well as in edible fats and oils, waxes, and vitamin A preparations. BHA is also used as a food preservative and as an ingredient in some Over-the-Counter (OTC) medicines.

Safety Information

The Food and Drug Administration (FDA) includes BHA on its list of substances considered Generally Recognized As Safe (GRAS) as a preservative for food. It may be used in food at concentrations not to exceed 0.02% of the total fat or oil content of a particular food.The safety of BHA has been assessed by the Cosmetic Ingredient Review (CIR)Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that BHA was safe as a cosmetic ingredient. In 2003, the CIR Expert Panel considered available new data on this ingredient and reaffirmed the above conclusion.

CIR Safety Review: At concentrations used in cosmetics and personal care products, BHA is not an eye irritant, nor it is a dermal irritant or sensitizer. Laboratory studies indicate that BHA is not a reproductive toxicant. BHA can inhbit the mutagenic and carcinogenic activity of some compounds. Following oral exposure, some studies indicate that high doses caused forestomach tumors in rodents.

As humans do not have forestomachs, these tumors were not considered relevant to humans. The CIR Expert Panel concluded that BHA was safe for use in cosmetic products.

BHA may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.

The Joint FAO/WHO Expert Committee on Food Additives has established an estimate of the Acceptable Daily Intake at 0-0.5 mg/kg body weight for BHA, BHT, TBHQ, or the sum of the three compounds.

More Scientific Information

BHA is a mixture of isomers of tertiary butyl-substituted 4-methoxyphenols that is used as an antioxidant. Antioxidants are ingredients employed in cosmetics to prevent or retard product spoilage from rancidity (or deterioration from reaction with oxygen).Antioxidants play a vital role in maintaining the quality, integrity, and safety of cosmetic products.
