USES

Mono-propylene glycol

• Propylene glycol is used as chemical feedstock for the production of unsaturated polyester resins

• It reacts with propylene oxide to give oligomers and polymers that are used in polyurethane application

• As an humectant, solvent and preservative in food and for tobacco products, as well as being the major ingredient in the liquid used in electronic cigarettes combined with vegetable glycerine

• As solvent in pharmaceutical and personal care products including oral, injectable and topical formulations, such as for diazepam and clonazepam that are insoluble in water, propylene glycol used as a solvent in their clinical, injectable forms

• It have tendency to lower the melting point of water, so it is used as aircraft de-icing fluid and also used as automotive antifreeze

• As minor ingredient in the oil dispersant

Di-propylene glycol

• Its higher viscosity and greater solvency for some materials makes choice compare to other glycol

• Used in hydraulic brake fluid formation along with castor oil

• Used in cutting oils, industrial soap and lubricants due to its affinity in other oil also

• Used as reactive monomer in product on of polyurethane, plasticizers and polyester

• Used in perfuminary industry as it having low odor and is standard base formulating solvent

Tri-propylene glycol

• Has ability to solubilize printing ink so it is used in cream formulation which removes inks stains from the hand

• Used in textile soap due to its solubility power for water and organic compounds and as well low volatility

• Used in cutting oil concentrate and lubricants formulations

• Used to produce acrylate resins

• Used in production of adhesives, inks and radiation cured coatings

• Alkylation of TPG results polyether which is used for the manufacturing of urethane rigid foam insulation
