Glycerol ●
TL;DR. This ingredient is primarily a humectant, helping formulas bind water and reduce moisture loss from skin and hair. It also serves as a water-phase solvent and texture support in creams, cleansers, serums, and oral care.
What does Glycerol do in a cosmetic formula?
This ingredient is primarily a humectant, helping formulas bind water and reduce moisture loss from skin and hair. It also serves as a water-phase solvent and texture support in creams, cleansers, serums, and oral care.
Is Glycerol clean?
It is widely accepted in clean-beauty frameworks and is generally well tolerated, with low irritation potential at typical cosmetic use levels. Clean-standard friction is minimal, with attention mainly on source transparency and processing quality.
Is Glycerol sustainable?
This material is commonly derived from plant oils or produced as a coproduct of soap and biodiesel manufacturing, though synthetic routes also exist. It is readily biodegradable and has a favorable environmental profile when responsibly sourced.
Is Glycerol COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when the feedstock and processing meet the standard’s requirements. From a Green Chemistry perspective, it aligns well when plant-derived or coproduct-based, biodegradable, water soluble, and made through relatively simple processing.
How does Glycerol work chemically?
The molecule is a small, highly hygroscopic three-carbon triol with three hydroxyl groups, which explains its strong water-binding behavior and full water miscibility. Typical use levels range from about 2% to 10% in leave-on products and can be higher in rinse-off or oral care, with broad pH stability and possible tackiness at elevated levels.
