Butylated+hydroxyanisole


 * Butylated hydroxyanisole**

An antioxidant formed from 2 isomeric, 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. It is a waxy solid used as a food additive and preservative. It is also used in medicines and petroleum products, which range vastly in our every day materials. Some believe in high doses butylated hydroxyanisole is a carcinogen, something that may cause an increase in cancer. Though no conclusive evidence is widely accepted as it being a carcinogen.

Since 1947, BHA has been added to edible fats and fat-containing foods for its antioxidant properties as it prevents food from becoming rancid and developing objectionable odors. Like butylated hyroxytoluene(BHT), the conjugated aromatic ring of BHA is able to stabilize free radicals, sequestering them. By acting as free radical scavengers, further free radical reactions are prevented.

**Immediate Health Effects**

 * If SWALLOWED, butylated hydroxyanisole is Moderately Toxic
 * If ABSORBED THROUGH SKIN, butylated hydroxyanisole is Not Available
 * If INHALED (SNIFFED OR BREATHED IN), butylated hydroxyanisole is Not Available

**Longterm or Delayed Health Effects**

 * Allergen
 * Suspected Endocrine Disruptor = May interfere with, mimic or block hormones

**Other**

 * In test animals, BHA has caused cancer in the forestomach. Humans do not have a forestomach, although the cause of any kind of tumors in animals is cause for concern.
 * A probable carcinogen. There is no data on caner effects in humans but there are enough animals studies to conclude that it is a carcinogen in humans.
 * In test tube studies, BHA has mimicked the hormonal actions of estrogen.
 * Repeated contact with skin may cause irritation and skin allergies/dermatitis.
