Metanil yellow is a yellow azo dye. Due to its toxic effect on the liver, brain and reproductive organs, the use of metanil yellow in the food industry is not permitted. Despite its status, metanil yellow was found in 16.4% of the sampled food products in India. It was used to color bakery goods, cereals, beverages, candies, gelatin, and numerous other commodities. Metanil yellow is used as an adulterant for curcumin in the turmeric powder.

Dinoseb, a herbicide that was widely used for weed-control when producing crops like soybeans, vegetables, fruits, and nuts, or citrus. It also killed insects in grapes and was used to dry seed crops. It was banned because it possessed dangers of birth defects and sterility for farm workers. However, it’s still used in some countries, e.g., China, evidenced by the fact that it is found in rain- and drinking water.

1-o-Tolylbiguanide is a chemical used as an antioxidant in cosmetics and soaps produced from animal or vegetable oil, and as a hardener for decorative and protective powder coatings. In the polymer industry o-tolyl biguanide is used as vulcanization accelerator and epoxy resin curing agent.

Stearic diethanolamide is derivative of stearic acid. It was used in the textile-processing industry as a fabric softener and plasticizer for sizings. Stearic diethanolamine is contained in coconut oil diethanolamine condensate, which is widely used in cosmetic formulations of bath oil, shampoo, conditioner, lipstick and hair dye.

STANNOUS TARTRATE is a white powder, soluble in water. It is used in dyeing and printing textiles. STANNOUS TARTRATE may cause skin, respiratory and serious eye irritation.

Dichlorodifluoromethane, also known as Freon 12, was used as a refrigerant and aerosol spray propellant. However, its production was banned, because of the destroy the ozone layer. Experiments on animal failed to show any carcinogenic effects of this compound.

Acetic anhydride is an esterification agent for use in prepn. of modified food starch and for acetylation of monoglycerides. Acetic anhydride is a versatile reagent for acetylations, the introduction of acetyl groups to organic substrates. Acetic anhydride is the chemical compound with the formula (CH3CO)2O (commonly abbreviated Ac2O). Ac2O is mainly used for acetylations leading to commercially significant materials. Its largest application is for the conversion of cellulose to cellulose acetate, which is a component of photographic film and other coated materials. Similarly it is used in the production of aspirin, acetyl salicylic acid, which is prepared by the acetylation of salicylic acid. It is also used as a wood preservative via autoclave impregnation to make a longer lasting timber. Ac2O is also used in many industrial processes for the production of plastics, textiles, dyes, photochemical agents, perfumes, explosives and cigarette filters. Because of its use for the synthesis of heroin by the diacetylation of morphine, acetic anhydride (known as 'AA' in clandestine chemistry circles) is listed as a U.S. DEA List II Precursor, and restricted in many other countries.
