Zinc stearate is a mild antiseptic and astringent, and it has been used as a local soothing application for inflammatory and irritating skin diseases. Zinc stearate is primarily used in pharmacuetical formulations as a lubricant in tablet and capsule manufacture at concentrations up to 1.5% w/w. It is a protective agent used in powders and ointments in the treatment of eczema, acne, and other skin diseases. GRAS - Zinc stearate complies with FDA Standard CFR 21 sections 177.2600, 182.8994 and 178.2010.

Pastaron (Urea) is a waste product of many living organisms, and is the major organic component of human urine. It is a very important starting material in a number of chemical syntheses, and is used on an industrial scale for the manufacture of fertilizers, pharmaceuticals, and resins. Urea is an osmotic diuretic similar to mannitol but more irritant. Applied topically, urea promotes hydration of keratin and mild keratolysis in dry skin. It increases water uptake by the stratum corneum and has an antipruritic effect. Pastaron is used to soften rough or dry skin caused by skin conditions such as eczema, psoriasis, keratosis, and others.

Chlorobutanol, or trichloro-2-methyl-2-propanol, is an analgesic and sedative hypnotic in man, and an experimental general anesthetic. It has antibacterial and antifungal properties. It is also used chemical preservative for parenteral drugs. It was found, that chlorobutanol inhibited mammalian Nav 1.2 channels at concentrations less than those used to preserve parenteral solutions. Its mechanism of inhibiting Na channels differs from that of local anesthetics in that it does not show use dependent or state dependent inhibition.

Chloroform is a colorless, sweet-smelling, dense liquid and widely used industrial and laboratory solvent. The total global flux of chloroform through the environment is approximately 660 000 tonnes per year, and about 90% of emissions are natural in origin. Many kinds of seaweed produce chloroform, and fungi are believed to produce chloroform in soil. Chloroform is used as an industrial solvent and as an intermediate in the manufacture of polymeric materials. The major use of chloroformtoday is in the production of the refrigerant R-22, commonly used in the air conditioning business. Inhaled chloroform anesthesia was introduced in 1847 and Chloroform subsequently became the most widely used volatile anaesthetic, and was used in horses before the end of the 19th century. Pure chloroform is known to be decomposed by the air with the formation of hydrochloric acid, phosgene and carbon dioxide. Phosgene is also generated metabolically from chloroform, and liver and kidney damage can ensue from its production.

Diethyl ether (ether) had been widely used for anesthesia until the 1960s despite its explosive properties and toxicity to both humans and animals. Diethyl ether still serves a role today as an effective inhalation agent. Newer inhalation agents have replaced ether completely and open drop delivery systems have been exchanged for complicated vaporizers and monitoring systems. Anesthesia in the developing world, however, still closely resembles primitive anesthetics.

Potassium ferrocyanide is an inorganic compound, a cyanide salt of Fe(2+). It is known under E code E 535 and is used in the food industry as an anticaking agent (substances that prevent powdered and granulated ingredients from lumping) in salt. Potassium ferrocyanide has low acute toxicity and is not mutagenic or carcinogenic. Its absorption from the gastrointestinal tract is low, and there is no accumulation in human.

Calcium salicylate is the calcium salt of salicylic acid. The anti-cancer effectiveness of calcium salicylate has been investigated on human HT-1080 fibrosarcoma cell lines. Low calcium salicylate concentrations did not retard tumor growth progression significantly but its cytotoxic characteristics were proven to be prominent by various morphological and immunocytological techniques - approximately 25% apoptosis after treatment with calcium salicylate. This compound up-regulated the expression of p53, p21 and Bax, and down-regulated Bcl-2 in HT-1080 cells. In addition, calcium salicylate is used in root canal filling material development.
