Phenethyl alcohol, or 2-phenylethanol, is an aromatic alcohol with a rosy scent. It is widely used in the food, fragrance, and cosmetic industries. It is used in the formulation of eye area makeup, skin care products, shampoos, perfumes, and colognes. Promising sources of natural 2-phenylethanol are microorganisms, especially yeasts, which can produce it by biosynthesis and biotransformation.

Nicarbazin, a complex of two compounds, 4,4'-dinitrocarbanilide (DNC) and 4,6-dimethyl-2-pyrimidinol (HDP) is an effective drug for preventing intestinal and caecal coccidiosis in poultry. It is used for prevention rather than the treatment of disease. Nicarbazin was the first agent with “broad‐spectrum” activity against Eimeria spp. of chickens. Nicarbazin is used as a single agent or in combination with polyether antibiotics (narasin, or maduramicin), roxarsone, or antibiotics (lincomycin, bacitracin, flavomycin) for prevention and control of coccidiosis caused by Eimeria spp. (all relevant species) in broiler chickens. Nicarbazin can cause increased sensitivity to heat stress, which may result in growth depression and even mortality in broilers; death may be due to cell degeneration processes in liver and kidneys; at the recommended dose, the drug causes occasionally toxic effects in laying hens like reduced hatchability and interruption of egg-laying. Nicarbazin interferes with the formation of the vitelline membrane, separating the egg yolk and egg white. The exact mode of action is unknown, although it is thought nicarbazin interferes with cholesterol metabolism in the formation of the membrane.

Betiatide (CAS 103725-47-9; aka S-benzoylmercapto¬acetyltriglycine or 2-[[2-[[2-[(2-benzoylsulfanylacetyl)¬amino]¬acetyl]¬amino]¬acetyl]¬amino] acetic acid) is the API in TechneScan MAG3™; a kit for the preparation of technetium Tc 99m mertiatide. It is used in the diagnosis of congenital and acquired abnormalities, renal failure, urinary tract obstruction and calculi. Furthermore it is used in providing renal function, split function, renal angiograms and renogram curves for whole kidney and renal cortex. Betiatide is light sensitive and must be protected as such.

Squalane is an emollient used as cosmetic ingredient. It naturally occurs in small amounts in the lipid layers of skin, and along with its precursor squalene, prevents moisture loss while restoring skin’s suppleness and flexibility. It is soluble in all common cosmetic media, and can be used without limits in all types of formulations being non-toxic and a non-irritant. It is used in skin care products as an active or inactive ingredient and can be used in emulsion composition in vaccines and some drug compositions. Squalane is a hydrogenated squalene - a natural product first extracted from shark liver oil, and later isolated from olive and palm oils. In a pure state, it is a mobile, colorless, odorless and tasteless hydrocarbon oil with good physical and chemical stability. Up to date, anticancer, antioxidant, drug carrier, detoxifier, skin hydrating, and emollient activities of squalane have been reported both in animal models and in vitro environments.

Enrofloxacin was developed by Bayer for the treatment of broad spectrum of bacterial infections in animals (cats and dogs). The drug exerts its action by inhibiting DNA Topoisomerase II (Gyrase) and DNA Topoisomerase IV (Topo IV), two major bacterial topoisomerase. Enrofloxacin was shown to be metabolized to ciprofloxacin and may cross the blood brain barrier in the animals.

Parabens are widely used preservatives in basic necessities such as cosmetic and pharmaceutical products. It was found, that butylparaben has estrogenic and antiandrogenic properties and is known to reduce sperm counts in rats following perinatal exposure. In addition was observed, that butylparaben exerted endocrine disrupting effects on both male and female offspring. In 2009-2010, 80 pregnant women from Ottawa Canada participated in the Plastics and Personal-Care Product Use in Pregnancy (P4) Study. Women kept a diary of products that they used 24 h prior to and during the collection. All parabens measured in maternal urine had moderate to high reproducibility. Women who used lotions in the past 24 h had significantly higher geometric mean paraben concentrations (80-110%) in their urine than women who reported no use in the past 24 h. Women who used shampoo, conditioner, and cosmetics also showed 70-80% higher butylparaben concentrations in their urine.

Butylated hydroxytoluene, commonly known as BHT, is an organic compound that is used in the food, cosmetic, and pharmaceutical industry as an antioxidant. BHT is a substituted derivative of phenol. BHT helps to prevent the formation of free radicals and oxidation. When used in food products, it delays oxidative rancidity of fats and oils, and prevents loss of activity of oil-soluble vitamins. It may be found in pharmaceutical gels, creams and liquid or gelatin capsules, tablets and other pharmaceutical dosage forms. The ability of oral BHT to lead to cancer is a controversial topic, but most food industries have replaced it with butylated hydroxyanisole (BHA). BHT was first used as an antioxidant food additive in 1954. BHT does have other commercial uses, as in animal feeds and in the manufacture of synthetic rubber and plastics, where it also acts as an antioxidant. The U.S. Food and Drug Administration has deemed that BHT is safe enough when used in limited concentrations. It currently permits its use in concentrations of about 0.01% to 0.02% in most foods. As an emulsion stabilizer in shortening, it may be used in a somewhat higher concentration, 200 parts per million.

Hydroxycitronellal is a perfume ingredient with a medium strength floral scent, reminiscent of lily and sweet tropical melon. It is produced synthetically from naturally occurring scent chemical citronellal. It is on the CFR - Code of Federal Regulations Title 21 list of synthetic flavoring substances and adjuvants. Hydroxycitronellal is banned in the European Union because of its toxic properties. Hydroxycitronellal is an allergen. Hydroxycitronellal has being shown to consistently modulate CCR5, CCL27, CCL2 and CCR7 in immature dendritic cells. Hydroxycitronellal is a TRPM8 agonist.
