Propanedi ●
TL;DR. This ingredient is primarily used as a humectant and solvent, helping formulas hold water, dissolve other materials, and improve skin feel without a heavy finish.
What does Propanedi do in a cosmetic formula?
This ingredient is primarily used as a humectant and solvent, helping formulas hold water, dissolve other materials, and improve skin feel without a heavy finish.
Is Propanedi clean?
It is generally well tolerated, with low irritation potential at typical cosmetic use levels. Clean-beauty frameworks usually view it as unproblematic when purity is well controlled.
Is Propanedi sustainable?
This material is commonly made from plant-derived fermentation feedstocks, although petrochemical routes also exist. It is readily biodegradable and does not raise major persistence or bioaccumulation concerns.
Is Propanedi COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic when made from approved renewable feedstocks and compliant processing routes. Its biodegradability and bio-based production pathway fit well with Green Chemistry principles.
How does Propanedi work chemically?
The molecule is a small, water-miscible diol with two hydroxyl groups, which explains its humectant, solvent, and sensory-support roles. It is typically used around 1 to 10 percent, is broadly pH-stable in cosmetic systems, and can also support preservation by lowering water activity.
