Basic Info

N-Acetyl-L-cysteine (CAS No. 616-91-1), universally known as NAC, is a premium acetylated derivative of the sulfur-containing amino acid L-cysteine. Appearing as a highly stable, white crystalline powder, this essential compound serves as the ultimate, direct precursor to cellular glutathione (GSH)—the human body’s master antioxidant. Structurally, the attached acetyl group significantly enhances the molecule’s bioavailability and structural stability compared to standard L-cysteine, allowing it to efficiently cross biological membranes and deliver active sulfhydryl groups straight to cellular targets.
 
At Zhishang Chem, we recognize that the global wellness, pharmaceutical, and dermatology sectors demand absolute purity and molecular stability. As a premier N-Acetyl-L-cysteine manufacturer, we utilize state-of-the-art organic synthesis and precision crystallization technology to deliver a superior grade of NAC crystalline powder. Our product features exceptional flowability and minimal free-sulfur odor, making it the perfect foundation for high-end capsule formulations, tablets, effervescent drink mixes, and advanced skin-brightening topical treatments.

In the highly sensitive pharmaceutical and nutraceutical fields, product safety, regulatory alignment, and source traceability are non-negotiable requirements for global market distribution. Zhishang Chem ensures that every batch of N-Acetyl-L-cysteine satisfies strict international regulatory frameworks, facilitating seamless compliance audits for your brand:

  • Pharmacopeia Standard Alignment:Our material rigorously complies with the latest monographs of the United States Pharmacopeia (USP) and European Pharmacopoeia (EP).
  • ISO 9001:2015 Certification:Our complete industrial manufacturing chain, from raw material validation to final crystal milling and automated packaging, operates under a verified quality management system.
  • Kosher & Halal Certified Ready:Manufactured via a 100% animal-free, synthetic fermentation-derivative pathway. The production lines are strictly monitored to ensure zero cross-contamination, making it suitable for strict vegan and religious-compliant product lines.
  • Global Export Documentation Package:To expedite customs clearance, we supply complete GHS-compliant Safety Data Sheets (SDS), TSE/BSE-Free Statements, Allergen-Free Declarations, and non-GMO certification with every bulk contract.

Product Packaging

Thanks to its robust cellular protective mechanism and reactive chemistry, our N-Acetyl-L-cysteine acts as a multi-functional powerhouse across three primary industries:

  • Dietary Supplements & Nutraceuticals:Extensively utilized as a foundational antioxidant raw material in liver detoxification complexes, respiratory health formulas, and cellular longevity ingredient It works by replenishing intracellular glutathione stores to combat systemic oxidative stress.
  • Cosmetics & Anti-Aging Skincare:Actively formulated in premium topical serums, brightening creams, and skin barrier balms. NAC safely interrupts the tyrosinase activation cascade, effectively reducing melanin synthesis while boosting skin elasticity through dermal tissue protection.
  • Pharmaceutical Formulations:Deployed as a reliable mucolytic agent in cough remedies and a vital stabilizer for various complex molecular structures.
  • Critical Formulation Tips:
  • Moisture & Oxygen Sensitivity:NAC powder is highly hygroscopic and susceptible to air oxidation. Final blending should be carried out under low-humidity conditions (RH < 40%) using inert gas purging if possible.
  • Incompatibility:Avoid direct contact with iron, copper, rubber, or alkaline substances. We recommend utilizing stainless steel (316L Grade) or glass-lined machinery during mixing. Incorporating chelating agents like citric acid or EDTA can further protect the active sulfhydryl groups from breakdown.

FAQ

A: Our standard commercial packaging for buy NAC powder bulk orders is a heavy-duty 25kg fiber drum lined with dual anti-static, heat-sealed PE inner bags to block moisture and eliminate powder dispersion during plant handling. For research institutes or indie brands conducting bench-scale optimization, we can provide specialized 1kg or 5kg aluminum foil bags as a trial MOQ.

A: Traditional low-grade synthesis pathways leave behind volatile free-sulfur intermediates, resulting in a harsh odor that ruins consumer acceptance. Zhishang Chem utilizes an advanced low-temperature vacuum crystallization and multi-stage fluid-bed drying protocol. This proprietary process completely drives off volatile impurities, yielding a premium crystal with an exceptionally clean and mild scent profile, which significantly simplifies flavor-masking in oral applications.

A: Many commercial entities operate strictly as traders, compounding market price spikes and logistics delays. As an integrated amino acid derivatives supplier, Zhishang Chem maintains extensive, long-term upstream supply agreements for core raw materials. By maximizing manufacturing throughput and automating the crystallization loop, we bypass intermediate trade markups, enabling us to guarantee a highly stable, competitive wholesale NAC price even during periods of global supply chain volatility.

Self-Inspection & Quality Control (Strict Purity & Trace Metal Standards)

Because trace metallic impurities or moisture can accelerate the oxidation of active sulfhydryl groups into ineffective disulfides, Zhishang Chem enforces an rigorous, multi-tiered self-inspection strategy within our analytical testing center:

  • Assay Purity (by High-Performance Liquid Chromatography / Titration):0% to 101.0% (Calculated on the dried substance).
  • Specific Optical Rotation:+21.0° to +27.0° (Verifying absolute isomeric purity and elimination of D-enantiomers).
  • State of Solution (Transmittance):≥ 95.0% Minimum (Ensuring a perfectly clear, sediment-free liquid phase when dissolved).
  • Heavy Metals & Arsenic Restrictions:Total heavy metals (as Pb) ≤ 10 ppm; Arsenic (As) ≤ 1 ppm; Iron (Fe) ≤ 10 ppm. (Crucial for preventing catalytic oxidation in wet formulations).
  • Loss on Drying:≤ 0.5% Maximum.
  • Residue on Ignition:≤ 0.1% Maximum.
  • Traceability Promise: We completely eliminate commodity trade uncertainty. An authentic, batch-tied Certificate of Analysis (COA) generated by our advanced laboratory accompany every physical shipment, ensuring the chemical metrics perfectly align with your high-standard processing requirements.
