Arginine Aspartate

Product Description

Green Stone Swiss manufactures cosmetic-grade Arginine Aspartate as a defined 1:1 salt of L-arginine and L-aspartic acid for bulk skin-care and hair-care supply. Direct factory lots are released under GMP-aligned QC, with batch COA, TDS, and free samples so formulators can confirm assay, solubility, and color before scale-up.

Arginine Aspartate (CAS 7675-83-4; C₁₀H₂₁N₅O₆) is L-aspartic acid compounded with L-arginine (1:1). CosIng lists hair conditioning and skin conditioning as the official functions. The salt is very soluble in water and generally stable in aqueous solution, supplying two NMF-related amino acids in a single crystalline raw material rather than a mixed protein hydrolysate. Typical aqueous solutions sit near circumneutral pH, which simplifies incorporation into leave-on skincare and rinse-off hair systems.

Brands use Arginine Aspartate in hydrating serums, creams, conditioners, and hair treatments that need a high-purity amino acid salt with documented identity. GSS factory-direct supply supports replenishment from sample to production with full technical documentation.

Key Benefits & Applications

Arginine Aspartate is a CosIng-listed 1:1 arginine–aspartate salt used for skin conditioning and hair conditioning in professional aqueous formulas.

• Skin-conditioning amino acid salt that supports NMF-style hydration and comfortable barrier feel
• Hair-conditioning support for softness, combability, and managed hair feel in rinse-off and leave-on systems
• Very water-soluble crystalline salt with clearer identity control versus mixed protein hydrolysates
• Compatible with hydrating serums, creams, conditioners, hair masks, and scalp-care aqueous bases
• Stable in aqueous solution across circumneutral pH with broad formulation compatibility
• Typical use level: 0.1–2.0% in final formulation

Formulation Guidelines

Use these process notes to dissolve Arginine Aspartate cleanly in skin and hair formulas.

• Suggested Use Level: Typical 0.1–2.0% in final formulation
• pH Range: Suggested 5.0–7.5; typical aqueous solutions are near pH 6–7
• Addition: Predissolve in the water phase; add at or below 50°C (Typical)
• Compatibility: Compatible with hyaluronates, glycerin, and protein hydrolysates; avoid strong oxidizing agents; keep sealed because the salt is hygroscopic
• Combine with Silk Amino Acids for complementary free-amino-acid conditioning on skin and hair.
