Dipropylene Glycole

TL;DR. This ingredient is mainly used as a solvent, fragrance carrier, and humectant that helps dissolve aroma materials, actives, and preservatives while adding light moisture-binding properties.

What does Dipropylene Glycole do in a cosmetic formula?

This ingredient is mainly used as a solvent, fragrance carrier, and humectant that helps dissolve aroma materials, actives, and preservatives while adding light moisture-binding properties.

Is Dipropylene Glycole clean?

From a clean-beauty perspective, it is generally well tolerated and has low irritation potential at typical cosmetic use levels. The main friction is its synthetic, petroleum-linked origin, which makes it less aligned with natural-focused standards.

Is Dipropylene Glycole sustainable?

This material is usually made through propylene oxide chemistry, so sourcing is primarily fossil-based unless a verified bio-based route is documented. It is expected to biodegrade well and is not known for strong environmental persistence.

Is Dipropylene Glycole COSMOS-approved?

It is generally not permitted in COSMOS-natural or COSMOS-organic formulas because it is a synthetic petrochemical-derived solvent rather than an allowed natural-derived material. Its Green Chemistry profile is mixed, with efficient performance and low odor, but limited renewable-feedstock alignment.

How does Dipropylene Glycole work chemically?

The molecule is a small, water-miscible, three-oxygen solvent that is typically supplied as a mixture of structural isomers. It is stable across normal cosmetic pH ranges, compatible with water and many organic materials, and often used at low single-digit levels as a carrier or solubilizing aid.
