BHA & BHT Butylated Hydroxyanisole
SCA endorses products with the Toxic-Free Tick, that do not contain BHA and/or BHT. Butylated hydroxyanisole (BHA) is a synthetic phenolic food additive, it is commonly used in cosmetics & other formulations, to prevent oils, fats & shortenings from oxidating triggering deterioration & rancidity. “Butylated hydroxyanisole (BHA) is reasonably anticipated to be a hu- man carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.” - National Toxicology Program

HOW IS IT USED?
ScienceDirect.com says that the percentage useage is commonly 0.005% and, that
"Immunologic Butylated hydroxytoluene in chewing gum should be considered as a possible cause of unexplained food allergy." Synthetically manufactured preservatives: Butylated hydroxyanisole (BHA) and the related compound butylated hydroxytoluene (BHT) are often added to cosmetics and medicines as preservatives. Also processed foods like cereals, gum, fast food, snacks, processed potatoes, drinks, shortening etc.
RESEARCH - WHAT EXPERTS SAY
BHA is listed as a carcinogen under California's Prop 65.
NICNAS not restricted for use. Tier II ssessment October 2017.
WHAT IS BHA & BHT?
The National Toxicology Program classifies BHA as “reasonably anticipated to be a human carcinogen". In Europe BHA is an approved food additive, considered "possible carcinogenic". The FDA says BHA is generally safe.
In animal studies, BHA has been shown to produce liver damage and stomach cancers, and interfere with normal functions of the reproductive system and thyroid hormones.
BHA can be found in food, food packaging and personal care products. "In vitro estimations of the percentage hemolysis (50% hemolysis indicating a 50% toxicity level). showed that BHT is more toxic than BHA . This clearly indicates that at the concentrations of 0.75%, BHA and BHT are harmful to the blood. " - NCBI. BHT in Food is "Banned in England, and other European countries" - ABC News
