Arginine Hydrochloride
What is Arginine Hydrochloride?
Arginine Hydrochloride is the hydrochloride salt form of L-arginine, a naturally occurring amino acid found in proteins and produced through fermentation or synthesis. In cosmetics, it serves primarily as a skin conditioning agent and buffering component. It functions by attracting and retaining moisture in the skin's upper layers, helping to support the natural barrier function and maintain suppleness. As a pH adjuster, it stabilizes formulations to optimal levels for skin compatibility, preventing instability in products like serums, creams, and cleansers. This ingredient is water-soluble, making it ideal for aqueous-based skincare items. Derived from amino acid building blocks essential to skin proteins like keratin and collagen, it contributes to product efficacy without altering texture significantly. Regulatory bodies affirm its suitability for rinse-off and leave-on applications in personal care formulations.
