Di-propylene Glycol

TL;DR. This ingredient is used mainly as a solvent, humectant, and fragrance diluent. It helps dissolve aromatic materials, improve product slip, and reduce volatility in water-based and fragranced formulas.

What does Di-propylene Glycol do in a cosmetic formula?

This ingredient is used mainly as a solvent, humectant, and fragrance diluent. It helps dissolve aromatic materials, improve product slip, and reduce volatility in water-based and fragranced formulas.

Is Di-propylene Glycol clean?

It is generally well tolerated, with low odor and low sensitization potential compared with many smaller alcohol solvents. Clean-beauty friction comes from petrochemical origin and possible trace manufacturing residues rather than routine skin compatibility issues.

Is Di-propylene Glycol sustainable?

This material is usually petrochemical-derived. It is readily biodegradable with low bioaccumulation potential, but conventional supply is not renewable and depends on energy-intensive upstream chemistry.

Is Di-propylene Glycol COSMOS-approved?

It is generally not permitted in COSMOS-organic or COSMOS-natural finished products when sourced from conventional petrochemical routes. From a Green Chemistry view, strong solvency and biodegradability are positives, while fossil feedstock and epoxide-based manufacture reduce alignment.

How does Di-propylene Glycol work chemically?

This molecule is a small, water-miscible diol ether made as a mixture of structural isomers, giving high solvency with low volatility and low odor. It is commonly used around 1 to 10% as a solvent or humectant and can be higher in fragrance concentrates; it is broadly stable across normal cosmetic pH and has low oxidation concern under standard storage.
