Answer

The L-Arginine available is a 100% pure cosmetic grade (Free Base) raw material. It is highly suitable for various cosmetic applications, including hair care formulations.

In hair care, L-Arginine is commonly used to:

  • Strengthen hair: As an essential amino acid, it helps support hair structure.
  • pH Adjustment: Due to its high alkalinity (pH 10.5-12.0), it is often used to balance the pH of acidic formulas.
  • Scalp Health: It is known to help improve blood circulation to the scalp.

Technical Documents:

  • COA (Certificate of Analysis) and SDS (Safety Data Sheet): You can typically download these documents directly from the product page on the website. If they are not visible, please contact the support team with your order number or request, and they will provide the specific batch documents for you.

Usage Recommendations:

  • Solubility: Soluble in water (up to approximately 1.5%).
  • Usage Rate: 0.1% - 10% depending on the specific application.
  • Mixing: Dissolve in the water phase of your formulation.
