Description

DPG, short for Dipropylene Glycol, is a widely used solvent and diluent in perfumery and fragrance applications. It has a very mild odor, making it useful for diluting aroma chemicals and fragrance compositions without significantly changing their intended odor profile.

Unlike an aroma chemical that contributes a specific fragrance note, DPG primarily acts as a carrier and formulation aid. It can help improve handling, facilitate accurate dosing and create convenient pre-dilutions of powerful fragrance materials.

DPG is especially useful when working with high-impact aroma chemicals, crystalline materials and concentrated fragrance ingredients. It can also be used as a carrier in perfume oils, fragrance compounds and various personal-care applications.

Perfumers' Tip

DPG is particularly useful when you need to work with a powerful aroma chemical at a lower concentration. Creating a 10% or 1% dilution can make very strong materials easier to evaluate and dose accurately during formula development. It is also useful for preparing fragrance materials that are difficult to handle in their concentrated form.
