Science
Mechanism of Action
Operating at a molecular level, Glyceryl Lactate provides a dual action derived from its constituent molecules. The lactic acid component, a natural moisturizing factor (NMF) constituent, effectively binds and retains moisture within the skin, contributes to optimal epidermal thickness, and facilitates mild exfoliation by gently loosening dead skin cells. Simultaneously, the glycerol moiety functions as a potent humectant, drawing water from the environment and aiding in the robust fortification of the skin's protective barrier, thereby diminishing trans-epidermal water loss.

Stability
No specific optimal pH range has been identified for Glyceryl Lactate's stability. However, as a glyceryl ester, it demonstrates considerable versatility in formulation, often functioning as an oil-in-water (O/W) emulsifier and being compatible with various processing methods, including hot/hot, hot/cold, cold/cold, and pre-emulsion techniques.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed glyceryl monoesters, a category encompassing Glyceryl Lactate, safe for use in cosmetic ingredients under current practices and concentrations. While undiluted forms may induce minor, transient irritation on abraded skin, they are generally non-irritating at typical cosmetic concentrations and are not considered sensitizers. The lactic acid component of Glyceryl Lactate is additionally affirmed as Generally Recognized As Safe (GRAS) for food use by the FDA.
