Glycol Ether Cleaner

Glycol Ethers for Cleaners, Brochure F-60669, Union Carbide Corp., Conn., 1990. 

Glycol Ethers. Glycol ethers are produced by reaction of propylene oxide with various alcohols such as methanol, ethanol, butanol, and phenol. The products are the mono-, di-, and tripropylene glycol ethers. These products are used in protective coatings, inks, textile dyeing, cleaners, antiicing additives for jet fuel, and as chemical intermediates (276). 

Butyl glycol ethers, the largest volume derivatives of -butyl alcohol used ia solvent appHcations (10), are obtained from the reaction of 1-butanol with ethylene oxide. The most important of these derivatives, 2-butoxyethanol, is used principally ia vinyl and acryHc paints as well as ia lacquers and varnishes. It is also employed ia aqueous cleaners to solubilize organic surfactants. 2-Butoxyethanol [111-76-2] has achieved some growth at the expense of the lower alkoxyethanols (ie, methoxy and ethoxyethanol) because of 2-butoxyethanol s lower toxicity. 

Uses Preparation of butyl esters (e.g., butyl acetate, di-n-butyl phthalate), glycol ethers solvent for waxes, resins, gums, and varnishes hydraulic fluid ingredient in perfumes and flavors additive in deicing fluids polishes, floor cleaners, stain removers, and in some gasolines (antiicing) diluent for brake fluids humectant for cellulose nitrate.

On prolonged storage, glycol ethers have been shown to form peroxy compounds which can adversely affect the dyes normally used in glass cleaners. Morpholine, Ammonia, or other volatile amines may be used in place of the Monoethanolamine. 

Industrial uses of ethanol include solvents (especially for toiletries and cosmetics, coatings and inks, and detergents and household cleaners), and chemical intermediates (especially ethyl acrylate, vinegar, ethylamines, and glycol ethers). Most corn fermentation alcohol is used in fuel, industrial solvents and chemicals, and beverages. 

Synthetic ethanol has the following uses as a chemical intermediate (for ethyl acetate, ethyl acrylate, glycol ethers, ethylamines, etc.), 30 percent in toiletries and cosmetics, 20 percent as a coatings solvent, 15 percent as a raw material for vinegar, 10 percent in household cleaners, 7 percent in detergents, 5 percent in pharmaceuticals, 5 percent in printing inks, 3 percent and in miscellaneous uses, 5 percent. 

Glycol ethers are extensively used in industrial applications as solvents for the manufacture of lacquers, varnishes, resins, printing inks, and textile dyes as antiicing additives in brake fluids and as gasoline additives. In addition, they are used in consumer products such as latex paints and cleaners. 

Cleaning products are used regularly in most households These include dishwashing detergents, denture cleaners, toilet bowl cleaners, oven cleaners, drain cleaners, wood and metal cleaners and polishes, tub, tile, and shower cleaners, bleach and pool chemicals. Toxic chemicals contained in household cleaners include glycol ethers, aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, surfactants, and heavy metals J32l... 

Most paints used in the household today are water-based products. Significant quantities of paints, primers, and brush cleaners are washed down the drain during cleanup following painting. Water-based paints contain numerous toxic chemicals. These include pigments (many with heavy metals), biocides, glycol ethers, binders, amines, acrylate, and other polymer monomers, surfactants, aliphatic and aromatic hydrocarbons alcohols, ketones, and esters.

Solvent cleaners are generally free of builder salts. The cleaning efficacy depends on solvent-type compounds, such as glycol ethers. Solvent cleaners are less effective on particulate soiling, such as mud on floors however, they are effective against oily soiling, particularly on modern plastic surfaces. 

Window cleaners constitute a specialty within the solvent cleaner category. Because any residue left on glass after drying leads to streaking or an otherwise undesirable appearance, these products are highly dilute aqueous solutions containing extremely low surfactant levels — most often nonionic surfactants — and a combination of glycol ethers and isopropyl alcohol as the solvent system. 

U.S. Patent 5,798,324 discloses a glass cleaner containing a synthetic polymer thickener in the presence of certain glycol ethers, nonionic surfactants, and linear alcohols that increases viscosity synergistically. Cited compositions exhibit optimal vertical cling and ease of use. 

It can be seen from the structure of the glycol ethers (Figure 13.4) that if the alkyl chain is extended sufficiently then it begins to approximate the structure of simple nonionic surfactants, those of the ethoxylated alcohol family. This has led some chemical producers in recent times to introduce compounds meant to be hybrid chemicals with the properties of both solvent and surfactant. They are not at present used to any great extent in household cleaners, but remain a possibility for future formulations.

In 2005, about 650 million liters (170 million gallons) of ethyl alcohol were produced by the phosphoric acid method. Of that amount, 60 percent was used for industrial solvents in the manufacture of toiletries and cosmetics, coatings and inks, detergents and household cleaners, pharmaceuticals, and other products. The remaining 40 percent was used in the preparation of other chemical compounds, including ethyl acrylate, vinegar, ethylamines, ethyl acetate, glycol ethers, and miscellaneous materials.
