Glycols

MONOETHYLENE GLYCOL C2H4(OH)2

Other names: MEG, ethylene glycol, ethanediol; an organic chemical compound primarily obtained through the hydration process of ethylene oxide. In its pure form, it is a colorless, odorless, syrupy liquid with a sweet taste. Ethylene glycol is toxic, and ingestion can be fatal.
Applications
Ethylene glycol is mainly used in the production of polyethylene terephthalate (PET), a precursor for producing films and bottles, as well as polyester fibers. It is also utilized in the production of antifreeze fluids for engine radiators and as an intermediate agent in refrigeration systems.

Glycols

GLIKOL DIETYLENOWY C2H4(OH)2

other names: DEG, diethylene glycol, 2,2′-oxydiethanol; An organic chemical compound from the diol group, obtained in the ethylene oxide hydration process as a by-product during the synthesis of monoethylene glycol. It is a colorless, transparent, and odorless liquid with a slightly sweet taste. Hygroscopic with low volatility and low viscosity. It is an excellent solvent for water-insoluble chemical compounds and drugs.
Applications
Diethylene glycol is mainly used in the production of polyurethanes and unsaturated polyester resins. Additionally, diethylene glycol is used in the manufacture of furniture, shoe polishes, gypsum–cardboard boards, emulsifiers, cooling and defrosting fluids, as well as a drying agent for gas

Glycols

TRIETHYLENE GLYCOL HO(CH₂CH₂O)₃H

other names: TEG, triethylene glycol, 2,2’-(1,2-ethanediylbis(oxy))bis-ethanol Triethylene glycol is obtained through the hydration process of ethylene oxide as a byproduct during the synthesis of monoethylene glycol (MEG). A colorless, transparent liquid with high viscosity. Soluble in water and most organic solvents. It mixes without limitation with water due to the high presence of hydroxyl groups in its molecular structure.
Applications
Triethylene glycol is used for drying natural gas and liquefied natural gas, as well as in the production of plasticizers for polyvinyl butyral (PVB) polymers. It also serves as a solvent and lubricant in the production of pigments for coloring textile products, printing inks, dyes, and coloring pastes. Additionally, it is a raw material for producing polyester resins, polyols, and insecticides.

Glycols

PROPYLENE GLYCOL C3H8O2

other names: MPG, monopropylene glycol, propane-1,2-diol. An organic compound from the group of dihydroxy alcohols. At room temperature, it is a colorless, odorless, oily liquid with a sweet taste and high viscosity. Unlike ethylene glycol, it is non-toxic.
Applications:
Propylene glycol is used for eco-friendly radiator fluids, air conditioning, and heating systems; as a component in antifreeze and de-icing agents, e.g., in aviation; in the food industry (designated as E1520, used as a preservative or emulsifier and as a component of dyes and flavors); in the cosmetics industry (toothpaste, all types of emulsions, fragrance carrier); in the pharmaceutical industry (as a base in which the active ingredient of the drug is distributed); in the tobacco industry (to regulate tobacco moisture, as an additive preventing drying. In electronic cigarettes, it is a component of e-liquids, serving as a solvent for nicotine).
