Gly- Cerin ●
TL;DR. A primary humectant, it binds water in the formula and helps reduce transepidermal water loss from the skin. It also supports texture, slip, and preservative performance by lowering water activity at higher levels.
What does Gly- Cerin do in a cosmetic formula?
A primary humectant, it binds water in the formula and helps reduce transepidermal water loss from the skin. It also supports texture, slip, and preservative performance by lowering water activity at higher levels.
Is Gly- Cerin clean?
This ingredient is broadly accepted in clean-beauty standards and is usually well tolerated, including by sensitive skin. Irritation is uncommon at typical leave-on levels, though very high concentrations can feel tacky or draw water from the surface if a formula is poorly balanced.
Is Gly- Cerin sustainable?
This material is commonly produced from plant-derived oils or as a byproduct of biodiesel and soap manufacturing, though petrochemical routes also exist. It is readily biodegradable and has low environmental persistence.
Is Gly- Cerin COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed according to the standard. It aligns well with Green Chemistry when made from renewable feedstocks, with good biodegradability and low formulation burden.
How does Gly- Cerin work chemically?
The molecule is a small, highly water-soluble triol with three hydroxyl groups, which explains its strong water-binding behavior and compatibility with aqueous systems. Typical use levels are about 2% to 10% in leave-on skin care, higher in some rinse-off or treatment formats, and it is stable across normal cosmetic pH ranges.
