Glycine ●
TL;DR. This ingredient primarily acts as a skin- and hair-conditioning agent, humectant, and mild buffering component. It helps support water binding in formulas and is often used as part of amino-acid or natural moisturizing factor blends.
What does Glycine do in a cosmetic formula?

Is Glycine clean?
From a clean-beauty perspective, it is generally well tolerated, low in irritation potential, and not a common restricted-list concern. The main review point is source and manufacturing route, especially whether a brand is using fermentation, plant-derived, or synthetic grades.
Is Glycine sustainable?
This material may be made by fermentation, protein hydrolysis, or conventional chemical synthesis, so its sustainability profile depends on sourcing. It is water soluble, readily biodegradable, and not considered environmentally persistent.
Is Glycine COSMOS-approved?
It can be compatible with COSMOS-natural and COSMOS-organic standards when sourced and processed through approved routes, while fully synthetic grades may not meet certification requirements. It aligns well with Green Chemistry when made by fermentation or approved plant-based processing because it is simple, biodegradable, and used at low levels.
How does Glycine work chemically?
The molecule is the smallest alpha-amino acid and is zwitterionic in typical cosmetic pH ranges, with an isoelectric point near pH 6. It is highly water soluble, generally stable in aqueous formulas, and commonly appears around 0.1% to 2% in skin-care and hair-care products.
