Propanediel^ ●
TL;DR. This ingredient functions primarily as a humectant and solvent, helping formulas hold water while improving the dissolution and delivery of other ingredients. It can also support preservation systems by lowering water activity.
What does Propanediel^ do in a cosmetic formula?
This ingredient functions primarily as a humectant and solvent, helping formulas hold water while improving the dissolution and delivery of other ingredients. It can also support preservation systems by lowering water activity.
Is Propanediel^ clean?
This ingredient is generally well-tolerated and has a favorable standing in clean-beauty frameworks, especially when made by fermentation from plant sugars. It is not a common allergen and does not carry major restricted-list friction.
Is Propanediel^ sustainable?
This material is often made from renewable plant-derived feedstocks such as corn sugar, though petroleum-derived routes also exist. It is readily biodegradable and has low environmental persistence compared with many synthetic solvents.
Is Propanediel^ COSMOS-approved?
It is permitted under COSMOS natural and organic standards when sourced and processed according to the standard. Its best Green Chemistry fit comes from renewable fermentation sourcing, good biodegradability, and broad solvent utility that can reduce reliance on less preferred solvents.
How does Propanediel^ work chemically?
The molecule is a small, water-miscible three-carbon diol with two hydroxyl groups, which explains its humectant, solvent, and texture-modifying behavior. Typical use levels are about 1–10% for hydration and solvent support, and it is broadly stable across normal cosmetic pH ranges.
