Arginine at a Glance

Amino Acid: Naturally occurring in the body.

Antioxidant Benefits: Protects skin from oxidative stress.

Hydrating Properties: Supports natural skin moisture balance.

Surfactant Derivatives: Can be used to create gentle, biocompatible surfactants.

Safety Record: Proven safe for use in personal care products.

 

 

Chemical Composition and Function

Chemical Formula: C6H14N4O2

Key Roles in Skin:

Hydration: Arginine aids in the synthesis of proline and urea, both vital for maintaining skin moisture levels.

Antioxidant Protection: Helps neutralize free radicals, reducing oxidative damage and promoting a youthful appearance.

 

 

Mechanism of Action

Arginine's ability to enhance skin hydration stems from its role in the production of natural moisturizing factors (NMFs). By boosting the levels of proline and urea, arginine helps retain moisture, improving skin's elasticity and softness. Additionally, its antioxidant properties help combat damage caused by environmental stressors and aging.

 

 

Applications in Skincare and Haircare

Skincare Products: Commonly found in moisturizers, serums, and anti-aging treatments. Effective at concentrations up to 18% as determined by the Cosmetic Ingredient Review Expert Panel.

Haircare Products: Used to reduce damage from oxidative stress caused by coloring and bleaching processes.

Cosmetic Surfactants: Arginine derivatives are being researched for use in creating gentle, biocompatible surfactants.

 

 

Safety and Usage

The Cosmetic Ingredient Review Expert Panel has reviewed and affirmed the safety of arginine in cosmetic formulations. It is well-tolerated and has a long history of use in personal care products. The amino acid can be either animal-derived or synthetically produced; both forms offer equivalent benefits.
