ARGININE LAUROYL GLUTAMATE.

Valuable / CLEANSING, FOAMING, SURFACTANT - CLEANSING

Arginine Lauroyl Glutamate is an amino acid derivative combining the natural moisturizing and collagen-building benefits of arginine with the keratinocyte-promoting properties of glutamate. It forms a protective, skin-lipid-like film that fortifies the skin barrier and enhances moisture retention.

Science

Mechanism of Action

This ingredient functions by leveraging its constituent amino acids. Arginine acts as a natural moisturizing factor (NMF), contributing to skin hydration and collagen synthesis as a fundamental building block. It also offers potential benefits in enhancing microcirculation and aiding wound healing. Glutamate is crucial for skin metabolism, stimulates keratinocyte proliferation, and is involved in fibroblast collagen biosynthesis, which supports the formation of the cornified envelope. Similar to related compounds, Arginine Lauroyl Glutamate is expected to create a thin, protective film on the skin's surface, acting as an emollient and skin conditioning agent. This film assists in skin barrier recovery, improves rough skin texture, and shields against environmental irritants, allergens, and bacteria while locking in moisture.

Stability

Based on studies of related arginine glutamate, this compound has the potential to enhance the physical stability of formulations, particularly in weakly acidic to neutral pH conditions (5-7). It also contributes to pH stability through its natural buffering capacity. As an amphiphilic molecule, it can function effectively as an emulsifier and surfactant.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Arginine Lauroyl Glutamate has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. However, the broader class of amino acid alkyl amides, including Sodium Lauroyl Glutamate, has been deemed safe for cosmetic applications after sufficient safety data, even at concentrations up to 40%, was presented. Given that Arginine and Glutamate are naturally occurring L-amino acids, which are generally recognized as safe (GRAS) by the FDA for direct food additives, this ingredient is anticipated to pose a low risk of toxicity and immunogenicity.
