Butylatd Hydroxy Taluene/ Butylated hydroxyanisole
B.H.T (Butylatd Hydroxy Taluene)
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.BHT is an antioxidant. It may damage the protective outer layer of viral cells. This may keep the viruses from multiplying and/or doing more damage.

B.H.A (Butylated hydroxyanisole)
B.H.A (Butylated hydroxyanisole) is an antioxidant consisting of a mixture of two isomeric organic compounds, 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. It is prepared from 4-methoxyphenol and isobutylene. It is a waxy solid used as a food additive. The primary use for BHA is as an antioxidant and preservative in food, food packaging, animal feed, cosmetics, rubber, and petroleum products.BHA also is commonly used in medicines, such as isotretinoin, lovastatin, and simvastatin, among others.
Since 1947, BHA has been added to edible fats and fat-containing foods for its antioxidant properties as it prevents rancidification of food which creates objectionable odors. Like butylated hydroxytoluene (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.
