Science
Mechanism of Action
This ingredient operates as a humectant and skin conditioning agent by leveraging its numerous hydroxyl groups to attract and bind water molecules within the stratum corneum. This mechanism significantly boosts the skin's capacity for moisture retention, contributing to increased elasticity, improved skin volume, and a reduction in the visibility of fine lines.

The Formula
Formulation
Stability
For optimal stability and safety in general skincare formulations, TEA-Lactate should be incorporated at a pH value greater than 3.5. A critical formulation consideration is the prevention of N-nitroso compound formation, which can occur when Triethanolamine derivatives interact with N-nitrosating agents.

Safety
Safety Profile
The CIR Expert Panel has affirmed TEA-Lactate's safety for skincare applications up to 10% concentration, provided the pH is above 3.5. Its safety was re-evaluated in 2013, with a focus on ensuring non-irritating formulations and limiting free diethanolamine levels to safe practices. Regulatory bodies like SCCS also approve its use under specified restrictions, typically related to purity and concentration for cosmetic products. As a salt of lactic acid, it relates to other lactate salts generally recognized as safe by the FDA for food use, though TEA-Lactate itself has specific cosmetic use guidelines. Formulations must actively prevent the formation of N-nitroso compounds.
