Dibutyl sebacate (DBS) is an organic chemical which is mainly used as a plasticizer in the production of such plastics as cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers and other plastics. It is used for plastics in the food packaging industry, in medical devices, and for pharmaceutical applications. It is classified as mildly toxic by ingestion in humans and has shown experimental reproductive effects in animals; however, it is also approved by the US-FDA as a food additive to be used with the minimum quantity needed to produce the intended effect.

Butane is gaseous alkane with four carbon atoms. Normal butane can be used for gasoline blending, as a fuel gas, fragrance extraction solvent, either alone or in a mixture with propane, and as a feedstock for the manufacture of ethylene and butadiene, a key ingredient of synthetic rubber. Butane is known to be a suffocating gas with a narcotic action. Inhalation of butane can cause euphoria, drowsiness, unconsciousness, asphyxia, cardiac arrhythmia, fluctuations in blood pressure and temporary memory loss, when abused directly from a highly pressurized container, and can result in death from asphyxiation and ventricular fibrillation. Abuse is frequent because butane is easily available and its sale is not restricted. Cases of sudden death in teenagers have been increasing since the 1980s , and over the past few years, there have been an increasing number of publications on the subject.

Propane, an alkane that at standard temperature and pressure is a gas. It has a role as a food propellant. Propane in combination with butane was used for recreational inhalation in adolescents. That use caused to death. The compounds found in tissues and biological fluids were perfectly compatible with those contained in the containers used for the inhalation. The mechanisms of death were assessed in a combination of the direct toxicity of the compound and oxygen replacement.

Carbadox is a veterinary medicine, which was approved by FDA for the treatment of swine dysentery and bacterial swine enteritis. In 2016 the FDA announced its plans to withdraw the approval of Mecadox (carbadox) due to the concern that the drug may leave trace amounts of carcinogenic residue in pork that could pose a cancer risk to people, however, the drug is still marketing.

Propyl Gallate is the n-propyl ester of gallic acid (3,4,5-trihydroxybenzoic acid). It is soluble in ethanol, ethyl ether, oil, lard, and aqueous solutions of polyethylene glycol (PEG) ethers of cetyl alcohol, but only slightly soluble in water. Propyl Gallate currently is used as an antioxidant in a reported 167 cosmetic products at maximum concentrations of 0.1%. Propyl Gallate is a generally recognized as safe (GRAS) antioxidant to protect fats, oils, and fat-containing food from rancidity that results from the formation of peroxides. The biological activity of Propyl Gallate is consistent with its free-radical scavenging ability, with effects that include antimicrobial activity, enzyme inhibition, inhibition of biosynthetic processes, inhibition of the formation of nitrosamines, anesthesia, inhibition of neuromuscular response to chemicals, ionizing/ultraviolet (UV) radiation protection, chemoprotection, antimutagenesis, anticarcinogenesis and antitumorigenesis, antiteratogenesis, and anticariogenesis. Propyl gallate has being shown to be a hepatoprotector in vitro and in vivo.

D&C Green No. 5 is an FDA-approved, synthetic dye produced from petroleum or coal tar sources, that used in pharmaceuticals and cosmetics. D&C Green No. 5 may be safely used for coloring drugs and surgical sutures. In cosmetics, it can be used externally and in general cosmetics, including lipsticks, and cosmetics close to the eye.

Ethoxyquin (EQ) has been used as an antioxidant in animal feed for many years, but pharmacological use of EQ has never been evaluated in humans despite that small amounts of EQ exist in certain food items. The level of this antioxidant in animal feeds should not be higher than 150 ppm (U.S. FDA permissions). Ethoxyquin is rapidly absorbed from gastrointestinal tract of laboratory animals like rats and mice. Peak blood concentration of the compound is observed within 1 h. Distribution of EQ in animal body is similar when it is administered orally and intravenously. Small amounts of parent EQ were detected in liver, kidney, and adipose tissue and fish muscles. It is excreted predominantly as metabolites via urine. Ethoxyquin is also registered as an antioxidant to control scald (browning) in apples and pears. EQ-induced DNA damage in human lymphocytes in a dose-dependent manner. According to the studies on dogs and laboratory animals it was shown that ethoxyquin had little acute toxicity, except when it is administered parenterally. Values of LD50 for EQ are 1700 mg kg−1 bw (rats, oral gavage), 2000 mg kg−1 bw (rats, dermal treatment, 24 h), 900 mg kg−1 bw (mice, intraperitoneal administration), and 180 mg kg−1 bw (mice, intravenous administration).

D and C Red No. 28 (Red 28) FDA-approved color additive used in drugs and cosmetics, including lip and eye care products, face makeups, personal care products. It is also used in biological stains, inks, and lacquers for coating and dyeing paper. D and C Red No. 28 was also investigated for use as a fruit fly pesticide. A safe level of exposure for Red 28 is considered 1.25 mg/kg /day.

Dinitolmide (also known as zoalene) is a nitrobenzamide coccidiostat developed by Dow Company. The drug is approved by FDA for the prevention and control of coccidiosis in chickens and turkeys. Dinitolmide is hazardous for man as it may cause mutations. Thus the substance should be handle with extreme caution.

D&C Red No. 27 are fluorescein-based dyes that were approved in 1982 for use in drugs and cosmetics Cosmetic retail products containing this dye is primarily lipsticks and blushers. D&C Red No. 27 physically associated with non-aqueous aluminum or zirconium minerals (lakes) and used in lipsticks, blushers, make-up preparations, hair dyes and colors, rouges and face powders. The FDA lists D&C Red No. 27 as a safe additive for drugs and cosmetics as per FDA standards.
