Potassium bisulfite is a chemical compound with the chemical formula KHSO3. Potassium bisulphite is used for the preservation of colourless food materials such as fruit juices, squashes, apples and raw mango chutney. Potassium bisulfite solutions are used in a variety of different applications, including use as a food preservative (E228) to prevent spoilage and discoloration, as a preservative for pharmaceuticals (nebulizer solutions, parenterals, peritoneal dialysis solutions). It is also an antiseptic and sulfurous acid source, especially in brewing. Potassium bisulfite also functions as hair-waving/straightening agent. Potassium bisulfite is generally recognized as safe by FDA when used in accordance with good manufacturing or feeding practice, except that it is not used in meats or in food recognized as source of vitamin B1.

Sorbitan monopalmitate (Span 40) is a nonionic emulsifier, surfactant and food additive. The product of Croda Inc. Span 40 is used in skin care, hair care and decorative cosmetics. It is also used as an effector in compositions capable of facilitating penetration across a biological barrier. Inactive ingredient of some medications it improves transdermal delivery of drugs and is a potential carrier for topical drug delivery. In PLIAGLIS cream (lidocaine and tetracaine) sorbitan monopalmitate is used as an inactive ingredient. Sorbitan monopalmitate is a fatty acid sorbitan ester, yellowish brown wax, slightly soluble in isopropanol, xylene and liquid paraffin, insoluble in water, non-toxic.

Ethyl maltol, a key food additive, and flavor enhancer is safe and is the most common sweet-associated component in electronic cigarette liquids. Ethyl maltol binds to human serum albumin (HSA) by situating within subdomain IIA (site I) of HSA.

ISOAMYL ACETATE is an organic compound that is the ester formed from isoamyl alcohol and acetic acid. It is present in many fruit aromas, especially banana, and is used in banana flavoring. It is a clear colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents.

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.

Taurine is a semi-essential amino acid and is not incorporated into proteins. Taurine is considered conditionally essential because it cannot be synthesized by infants younger than 4-6 weeks, and it may not be adequately synthesized in patients receiving long-term parenteral nutrition and patients with short-term hypermetabolic conditions. In mammalian tissues, taurine is ubiquitous and is the most abundant free amino acid in the heart, retina, skeletal muscle, brain, and leukocytes. Taurin occurs naturally in fish and meat. The mean daily intake from omnivore diets was determined to be around 58 mg. Taurine is a component of energy drinks, with many contain 1000 mg per serving. In medicine, taurine supplementation demonstrated efficacy in relieving symptoms of heart failure, hepatitis, hypertension and psychotic disorder. Taurine exerts many physiological functions, including membrane stabilization, osmoregulation and cytoprotective effects, antioxidant and anti-inflammatory actions as well as modulation of intracellular calcium concentration and ion channel function. In addition taurine may control muscle metabolism and gene expression, through yet unclear mechanisms. The cellular and biochemical mechanisms mediating the actions of taurine are not fully known.
