Corn-Derived Propanediol ●
TL;DR. This ingredient is primarily a humectant and solvent, helping dissolve actives, improve spread, and reduce the tacky feel of water-based formulas. It can also support preservative systems by improving ingredient distribution in the water phase.
What does Corn-Derived Propanediol do in a cosmetic formula?
This ingredient is primarily a humectant and solvent, helping dissolve actives, improve spread, and reduce the tacky feel of water-based formulas. It can also support preservative systems by improving ingredient distribution in the water phase.
Is Corn-Derived Propanediol clean?
From a clean-beauty perspective, this ingredient is generally well tolerated, broadly accepted, and not a common restricted-list concern. Mild stinging or irritation is possible for very reactive skin at higher levels, but it has a low sensitization profile overall.
Is Corn-Derived Propanediol sustainable?
This material is commonly made by fermenting renewable plant sugars rather than relying on petroleum feedstocks. It is readily biodegradable and has a favorable environmental profile when the agricultural supply chain is responsibly managed.
Is Corn-Derived Propanediol COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic formulas when made from renewable feedstock by accepted fermentation and purification routes. It aligns well with Green Chemistry through bio-based sourcing, efficient aqueous processing, and ready biodegradability.
How does Corn-Derived Propanediol work chemically?
This molecule is a small, water-miscible three-carbon diol with two hydroxyl groups, which explains its humectant and solvent behavior. Typical use levels are about 1 to 10 percent, with higher levels possible in some systems, and it is stable across the usual cosmetic pH range.
