Product Overview

L-Arginine Hydrochloride (CAS 1119-34-2) is the hydrochloride salt form of L-arginine, a conditionally essential amino acid and nitric oxide (NO) precursor. Compared with free base L-arginine, it offers dramatically higher water solubility and a near-physiological pH (~5.7), making it the preferred form for liquid formulations, injections and clinical nutrition products.

We supply food grade and pharma grade. Food grade is widely used in dietary supplements, sports nutrition powders and instant dissolving drink mixes. Pharma grade is applied in amino acid injections, infusion solutions and oral liquid preparations. It is also used as a pH adjuster and stabilizer in cosmetic and pharmaceutical formulations. Compliant with USP, CP, BP, EP, JP and AJI standards, certified by ISO9001, ISO22000, HALAL, KOSHER and HACCP for global export.

Product Characteristics

1.Exceptionally high water solubility Freely soluble in water (~860 g/L at 25°C), far exceeding free base form — ideal for instant dissolving powders, beverages and liquid formulations.

2.Near-physiological pH (~5.7) Slightly acidic solution provides good compatibility with human blood, making it suitable for intravenous and oral liquid preparations.

3.Hydrochloride salt form of L-arginine Dissociates in vivo to release bioavailable L-arginine as NO precursor, same biological function as free base.

4.Stable crystalline powder White crystals or crystalline powder, stable in dry state, suitable for bulk storage and industrial production.

5.Dual-grade supply Food grade for nutraceutical and beverage applications; pharma grade for injection and clinical formulations.

Main Functions

1.Nitric oxide (NO) biosynthesis support Releases L-arginine as substrate for NO production, supporting vasodilation and healthy blood circulation.

2.Cardiovascular & circulatory nutrition Supports vascular health and normal blood flow through the L-arginine-NO pathway.

3.High-solubility amino acid fortification Enables rapid dissolution in liquid supplement drinks and reconstitutable powder products.

4.Clinical nutrition & infusion raw material Used in amino acid infusions and parenteral nutrition formulations for medical nutrition support.

5.pH buffer & formulation stabilizer Serves as a buffering and stabilizing agent in pharmaceutical and cosmetic formulations.

Main Applications

1. Dietary Supplements & Sports Nutrition

Widely used in pre-workout powders, amino acid drink mixes, capsule and tablet supplements targeting NO support, muscle pump, recovery and men’s health nutrition. Its high solubility makes it ideal for instant dissolving sports drinks and effervescent formulations.

2. Pharmaceutical Industry

Key raw material for amino acid injections, infusion solutions and oral liquid preparations. The hydrochloride form’s high solubility and blood-compatible pH (~5.7) make it the standard choice for intravenous arginine therapy and clinical nutrition products.

3. Functional Beverages & Instant Powders

Added to functional drink mixes and reconstitutable powder products requiring rapid and complete dissolution in water.

4. Cosmetic & Personal Care

Used as a pH adjuster and humectant/stabilizing ingredient in skincare formulations.

ECHEMI Editorial Reference

L-Arginine is the nitrogen donor for synthesis of nitric oxide, a potent vasodilator that is deficient during times of sickle cell crisis.Target: OthersArginine is an α-amino acid. It was first isolated in 1886. The L-form is one of the 20 most common natural amino acids. At the level of molecular genetics, in the structure of the messenger ribonucleic acid mRNA, CGU, CGC, CGA, CGG, AGA, and AGG, are the triplets of nucleotide bases or codons that code for arginine during protein synthes

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement

We keep traceable records for all delivered batches. If any quality concern arises, we act as your single point‑of‑contact to trace root causes with source factories, drive corrective actions and deliver practical resolution plans. Client feedback is systematically collected to optimize our supplier management and document‑review procedures.

We provide a comprehensive set of compliance documents to support your import and registration work. Our available documentation includes but is not limited to:

★ ISO Certification ★ Halal Certificate

★ Kosher Certificate ★ IP certificate

★ Haccp certificate ★ Allergens with Glutens

★ GRAS Statement ★ HACCP Program
