The use of IPM is recommended in the Sterility Test chapter of the European, Japanese and United States Pharmacopoeia (EP, 2.6.13, JP, 4.06 and USP, 71) as diluent for oils and oily solutions, as well as for ointments and creams. Indeed, its solvent properties improve the filterability of these samples.
Isopropyl myristate is known as a penetration enhancer for topical preparations. It is a water clear, low viscous oily liquid with a very good spreading capacity on the skin. Isopropyl Myristate is mainly used in cosmetics as an oil component for emulsions, bath oils and as a solvent for active substances.
It is a white crystal with corrosive to skin and toxic. It is soluble in water and methanol, slightly soluble in ethanol, insoluble in propanone and liquid ammonia. When it is in hot water decomposition will occur to release ammonia and ammonium bifluoride. It is white or colorless transparent orthorhombic crystal at room temperature, with a slightly sour taste. It is easily deliquescent when heated or in hot water and decomposes into ammonia and hydrogen fluoride. Decomposed in hot water, the aqueous solution is strongly acidic. It is obtained by neutralizing anhydrous hydrofluoric acid with liquid ammonia.
Mainly used as glass etching agent, wood and wine preservative, disinfectant, zirconium drops reagent and fiber mordant and reagents to extract rare elements.

Nitric acid is the inorganic compound with the formula HNO3. It is a highly corrosive mineral acid.[6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%.
Nitric acid is the primary reagent used for nitration â?? the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent.
Hydrogen sulfide is a hydride of sulfur with the chemical formula H2S. It is a colorless, foul-smelling (rotten egg) highly toxic gas. It is soluble in water and ethanol, with a specific gravity of 1.1906. The melting point is -85.5�°C, the boiling point is -60.4�°C, the critical temperature is 100.4�°C, and the critical pressure is 90.06�?105 Pa. The autoignition point is 260�°C, and it is flammable. It can cause explosive combustion when it encounters a spark. When mixed with air, it can cause an explosion, and the explosion limit is 4% to 44% (volume). It can react chemically with a variety of ions to produce water-insoluble sulfides, which can turn the surface of copper and silver black. It is widely present in the manufacturing industries of metal smelting, natural gas, hydrochloric acid and sulfuric acid. When manufacturing various sulfides such as sulfate pulp, rayon, artificial cotton, rubber, carbon disulfide, etc., hydrogen sulfide gas is often discharged. In some chemical reactions, unstable sulfur-containing compounds will also decompose into hydrogen sulfide. For example, in coking, refined petroleum and metal smelting, hydrogen sulfide, as a conventional waste gas, is very easy to leak into the air. The decomposition of sulfur dyes can also release hydrogen sulfide gas.
