Synthesis route :

The synthesis of Dipropylene Glycol is made from propane-1,2-diol (or Propylene Glycol) and 1,2-epoxypropane, in the catalytic presence of sulfuric acid. It is an ingredient produced in a large quantity, which earned it the HPVC label (High Production Volume Chemicals).

Synthesis precursor :

Dipropylene Glycol is not a precursor to the synthesis of another compound of olfactory interest.

Isomerism :

Dipropylene Glycol has three asymmetric carbons that give rise to three distinct isomers of this molecule. The DIPG used in perfumery is therefore a mixture of these enantiomers, with a different volatility.

Natural availability :

Dipropylene Glycol is not available in its natural state.

Allergens :

This ingredient does not contain any allergen.

Uses in perfumery :

Dipropylene Glycol is one of the most widely used solvents in perfumery. It is used in both fine and functional fragrance. It is the most common solvent found in perfume concentrates, as it is used to dilute raw materials, avoiding the use of alcohol. It is therefore used for its high capacity to dilute a wide variety of compounds.
DPG is the most suitable solvent for perfume concentrates for shower gel bases, shampoo, creams, deodorants, diffusers, fabric softeners, household products and dishwashing liquids, for stability reasons.
However, DPG should not be used in candle bases of any type. The flame of the candle would be too high.

Other names :

DPG, DIPG, 3-(3-hydroxypropoxy)propan-1-ol, oxydi-2-propanol, oxydipropan-1-ol, dihydroxyisopropyl ether, dimethyl diethylene glycol, oxydipropanol, dipropyleneglycol, dipropylenglykol, 1-(2-hydroxypropoxy)propan-2-ol, bis(2-hydroxypropyl)ether, oxybispropanol
