A chemical compound derived from an acid (organic or inorganic) in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides.
Monotallate esters of Polyethylene Glycol (PEG) of various molecular weights. They are soluble in water, have low volatility, give very effective wetting, lubrication and emulsification. Monotallate PEG Esters are used in cleaners, lubricants, greases and metalworking fluids.
