DESCRIPTION

Dipropylene Glycol (DPG) is a clear, odorless, low-volatility solvent widely used in professional perfumery and cosmetics. Its exceptional chemical stability and olfactory neutrality make it an essential ingredient for diluting essential oils, absolutes, aroma chemicals, and concentrated fragrances, ensuring homogeneous, safe, and high-quality formulations.

WHY IT IS USED IN PERFUMERY

DPG is chosen for its ability to make dense or poorly soluble raw materials easier to work with, without altering their aroma or olfactory nuances. It is especially useful for preparing sample dilutions, building complex accords, or as a secondary solvent in room fragrances, extracts, and aromatic bases.

Thanks to its low volatility, Dipropylene Glycol slows the evaporation of lighter components, acting as a soft fixative and contributing to a smoother, more long-lasting diffusion of the fragrance. Its complete olfactory neutrality also makes it ideal in processes where it is crucial not to contaminate or alter the scent profile.

Many perfumers prefer it for its excellent compatibility with ethanol and essential oils, allowing clear and stable blends even with ingredients that are naturally difficult to solubilize.

WHY IT IS USED IN COSMETICS

In cosmetics, Dipropylene Glycol is used as a solvent, humectant, and fragrance carrier. Its high compatibility with active ingredients, extracts, and perfumes ensures the uniform dispersion of fragrances in creams, lotions, deodorants, and personal care products.

DPG also helps maintain skin hydration by reducing transepidermal water loss and improving comfort on the skin. It is appreciated for its low irritancy and for the light, non-greasy feel it provides in cosmetic formulations.

Thanks to its versatility, it is considered a safe, stable, and multifunctional ingredient suitable for both leave-on products (such as creams and deodorants) and rinse-off products (such as cleansers and shampoos).
