MEG (Mono ethylene Glycol)
Monoethylene glycol (Ethylene glycol) is a colorless, virtually odorless and slightly viscous liquid. It is miscible with water, alcohols, aldehydes and many organic compounds. MEG will not dissolve rubber, cellulose acetate or heavy vegetable and petroleum oils. MEG has a low volatility and it is 50% more hygroscopic than glycerol at room temperature.
MEG is mainly used in the production of polyester, polyethylene terephthalate (PET) and antifreeze solutions. It is an important dehydrating agent, good humectant and an industrial solvent.
Salts of phosphoric acid have many uses in the food industry. They can act as buffers, acidulants for baking powders and emulsifying salts in the production of processed cheese.
