Science
Mechanism of Action
Lauroyl Lysine primarily functions as a skin and hair conditioning agent, imparting a luxurious, silky texture to formulations. On the skin, it establishes a protective barrier, effectively mitigating transepidermal water loss and preserving hydration. Its light-diffusing properties contribute to a soft-focus, matte appearance by minimizing shine and moderating skin oiliness. Furthermore, it acts as a sophisticated texture modifier, optimizing product spreadability, reducing pilling, and enhancing the longevity and water resistance of makeup through superior adhesion.

Stability
Lauroyl Lysine demonstrates exceptional thermal stability, with a decomposition temperature exceeding 200°C, making it suitable for high-heat manufacturing processes. As a fine powdery texture modifier, it significantly improves the flow and spreadability of oil/powder mixtures and effectively reduces issues like pilling or clumping, particularly in formulations containing elevated levels of hydrophilic thickeners. Optimal textural benefits are typically observed in compositions that are largely free from such hydrophilic solid powders.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Lauroyl Lysine safe for use in cosmetics at concentrations up to 45%, with the caveat that formulations should be non-irritating. While L-Lysine, its amino acid precursor, is recognized as a regulated nutrient by the FDA, Lauroyl Lysine itself does not have a specific FDA cosmetic status. No published clinical studies regarding reproductive, developmental, or carcinogenic toxicity were identified for amino acid alkyl amides, including Lauroyl Lysine.
