Panthenol (also called pantothenol) is the alcohol analog of pantothenic acid (vitamin B 5), and is thus a provitamin of B 5. In organisms, it is quickly oxidized to pantothenic acid. It is a viscous transparent liquid at room temperature. Panthenol is used in pharmaceutical and children's products as a moisturizer and to hasten wound healing.
Diethyl ether, or simply ether, is an organic compound with the chemical formula (CH 3 CH 2) 2 O, sometimes abbreviated as Et 2 O. [ a ] It is a colourless, highly volatile , sweet-smelling ("ethereal odour"), extremely flammable liquid .
Ethyl phenyl ether (or phenetole) is an organic compound that belongs to a class of compounds called ethers. Ethyl phenyl ether has the same properties as some other ethers, such as volatility, explosive vapors, and the ability to form peroxides. It will dissolve in less polar solvents such as ethanol or ether, but not in polar solvents such as ...
To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. For relatively simple ...
The trivial names for simple ethers (i.e., those with none or few other functional groups) are a composite of the two substituents followed by "ether". For example, ethyl methyl ether (CH 3 OC 2 H 5), diphenylether (C 6 H 5 OC 6 H 5). As for other organic compounds, very common ethers acquired names before rules for nomenclature were formalized.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Antifoaming agents reduce or prevent foaming in foods. Antioxidants Antioxidants such as vitamin C act as preservatives by inhibiting the effects of oxygen on food, and can be beneficial to health. Bulking agents Bulking agents such as starch are additives that increase the bulk of a food without affecting its nutritional value. Food coloring
