Bepanthen eye and nose ointment (Germany) A vial of nasal spray containing panthenol, manufactured in Italy In pharmaceuticals, cosmetics, and personal-care products, panthenol is a moisturizer and humectant, used in ointments, lotions, shampoos, nasal sprays, eye drops, lozenges, and cleaning solutions for contact lenses.
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. Diethyl ether is simply called ether, but was once called sweet oil of vitriol. Methyl phenyl ether is anisole, because it was originally found in ...
An ethoxy group (CH 3 CH 2 O−) is found in the organic compound ethyl phenyl ether (C 6 H 5 OCH 2 CH 3, also known as ethoxybenzene). Related to alkoxy groups are aryloxy groups, which have an aryl group singularly bonded to oxygen such as the phenoxy group (C 6 H 5 O−). An alkoxy or aryloxy group bonded to an alkyl or aryl (R−O−R') is ...
In chemistry, alkyl is a group, a substituent, that is attached to other molecular fragments. For example, alkyl lithium reagents have the empirical formula Li(alkyl), where alkyl = methyl, ethyl, etc. A dialkyl ether is an ether with two alkyl groups, e.g., diethyl ether O(CH 2 CH 3) 2.
Ethyl group (highlighted blue) as part of a molecule, as the ethyl radical, and in the compounds ethanol, bromoethane, ethyl acetate, and ethyl methyl ether. In organic chemistry , an ethyl group (abbr. Et ) is an alkyl substituent with the formula −CH 2 CH 3 , derived from ethane ( C 2 H 6 ).
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. It belongs to the ether class of organic compounds. It is a common solvent.
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 ...
Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, respectively.Typically, E-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while P-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives.
