Propanediol1 ●
TL;DR. This ingredient primarily acts as a humectant and solvent, helping pull water into the formula and dissolve actives, extracts, and fragrance components. It can also support preservative systems by improving formula water management.
What does Propanediol1 do in a cosmetic formula?
This ingredient primarily acts as a humectant and solvent, helping pull water into the formula and dissolve actives, extracts, and fragrance components. It can also support preservative systems by improving formula water management.
Is Propanediol1 clean?
From a clean-beauty perspective, it is generally well tolerated, low in irritation potential, and not a common restricted-list issue. It is often viewed more favorably when it comes from fermentation-based renewable feedstocks rather than petroleum routes.
Is Propanediol1 sustainable?
This material can be made from renewable plant sugars through fermentation, although petroleum-derived versions also exist. It is readily biodegradable, with the main sustainability questions tied to agricultural inputs and feedstock traceability.
Is Propanediol1 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when the source and manufacturing route meet the standard’s criteria. It fits Green Chemistry well when fermentation-derived, due to renewable carbon input, good biodegradability, and relatively benign solvent behavior.
How does Propanediol1 work chemically?
The molecule is a small three-carbon diol with two hydroxyl groups, which explains its water miscibility, humectancy, and solvent performance. Typical use levels are about 1 to 10 percent, with higher levels possible in some formats, and it is broadly stable across normal cosmetic pH ranges.
