Glycol ●
TL;DR. This ingredient is a small, water-miscible solvent and humectant used to dissolve water-soluble materials, adjust viscosity, and depress freezing point in water-based formulas. It is far less common in contemporary skin and hair care than related polyol solvents.
What does Glycol do in a cosmetic formula?
This ingredient is a small, water-miscible solvent and humectant used to dissolve water-soluble materials, adjust viscosity, and depress freezing point in water-based formulas. It is far less common in contemporary skin and hair care than related polyol solvents.
Is Glycol clean?
From a clean-beauty perspective, this material has significant standards friction because it is a small petrochemical solvent associated with systemic-exposure concerns at higher exposures. Many retailer and brand standards prefer other humectant solvents with broader cosmetic acceptance.
Is Glycol sustainable?
This material is commonly made from fossil feedstocks through high-volume petrochemical processing. It is readily biodegradable, but its nonrenewable sourcing and solvent-profile concerns weaken its sustainability standing.
Is Glycol COSMOS-approved?
It is not permitted as a conventional ingredient under COSMOS-natural or COSMOS-organic standards. It has some Green Chemistry positives through high water miscibility and ready biodegradability, but it fits poorly with renewable-feedstock and preferred-solvent principles.
How does Glycol work chemically?
The molecule is a very small, highly water-miscible two-carbon diol with two primary alcohol groups, which explains its solvent, humectant, and freezing-point-depression behavior. It is generally pH-stable in water and not a standard modern cosmetic humectant choice, with co-formulation decisions driven more by standards acceptance and exposure assessment than by performance need.
