Science
Mechanism of Action
Functioning primarily as a humectant and skin-conditioning agent, Alanine Glutamate effectively attracts and retains moisture within the stratum corneum, leading to significantly improved skin hydration. Its constituent amino acids, alanine and glutamic acid, are critical for this moisture retention, supporting a robust skin barrier. Additionally, alanine is known to contribute to collagen synthesis, vital for maintaining skin structure and elasticity.

The Formula
Formulation
Stability
Alanine Glutamate is readily soluble in water, facilitating its integration into aqueous formulations. While a specific optimal pH range for the dipeptide's stability has not been explicitly defined, the pKa values of its glutamic acid component suggest potential changes in protonation state around pH 4.07, with physiological pH ranges of 7.35-7.45 also being relevant for its activity.
Safety
Safety Profile
The safety of Alanine Glutamate is well-supported, primarily through the established safety of its individual amino acid components. The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that alpha-amino acids, including alanine and glutamic acid, are safe in current cosmetic uses. Furthermore, L-amino acids are generally recognized as safe (GRAS) by the FDA as direct food additives, reinforcing the benign profile of this dipeptide.
