Sodium glycinate

Sodium glycinate (CAS 6000-44-8, EC 227-842-3), also known as sodium aminoacetate, sodium glycine, or sodium glycocollate, is the sodium salt of the amino acid glycine. It carries no assigned E-code and is commercially supplied as moist beads under the molecular formula C2H5NO2.Na.

In personal care formulations, sodium glycinate functions as a skin and hair conditioner by binding moisture to the protein structure of hair and skin, while its buffering capacity stabilizes product pH in the mildly alkaline range. In food and pharmaceutical applications, it acts as an antioxidant and humectant, chelating metal ions that would otherwise accelerate oxidative degradation.

Sodium glycinate is available in cosmetic and technical grades, with procurement subject to REACH compliance within the EU. Suppliers typically offer documentation aligned with Ph.Eur. and FCC standards depending on the target application. Standard packaging formats include drums and intermediate bulk containers.
