Glycol Ethers
Glycol ethers are a class of chemical compounds consisting of alkyl ethers that are based on glycols such as ethylene glycol or propylene glycol. They are commonly used as solvents in paints and cleaners. They have good solvent properties while having higher boiling points than the lower-molecular-weight ethers and alcohols. History The name "Cellosolve" was registered in 1924 as a United States trademark by Carbide & Carbon Chemicals Corporation (a division of Union Carbide Corporation) for "Solvents for Gums, Resins, Cellulose Esters, and the Like". "Ethyl Cellosolve" or simply "Cellosolve" consists mainly of ethylene glycol monoethyl ether and was introduced as a lower-cost solvent alternative to ethyl lactate. "Butyl Cellosolve" ( ethylene glycol monobutyl ether) was introduced in 1928, and "Methyl Cellosolve" ( ethylene glycol monomethyl ether) in 1929. Types Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, resp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2-Butoxyethanol
2-Butoxyethanol is an organic compound with the chemical formula (Bu = ). This colorless liquid has a sweet, ether-like odor, as it derives from the family of glycol ethers, and is a butyl ether of ethylene glycol. As a relatively nonvolatile, inexpensive solvent, it is used in many domestic and industrial products because of its properties as a surfactant. It is a known respiratory irritant and can be acutely toxic, but animal studies did not find it to be mutagenic, and no studies suggest it is a human carcinogen.
