Basic Introduction to Cetyltrimethylammonium Chloride
Cetyltrimethylammonium Chloride (IUPAC Name: Hexadecyl(trimethyl)azanium chloride, CAS No. 112-02-7, commonly referred to as CTAC or Cetrimonium Chloride) is a cationic quaternary ammonium surfactant. Structurally composed of a C16 hydrophobic alkyl chain paired with a hydrophilic trimethylammonium headgroup, it exhibits robust surface activity, cationic charge density, antimicrobial properties, and thermal stability in aqueous and organic media.
To address the growing technical requirements of advanced manufacturing, Shandong Look Chemical Co., Ltd. offers high-purity Cetyltrimethylammonium Chloride produced under controlled crystallization and reaction protocols. Beyond its established roles in conditioning and industrial emulsification, our specialized grades are engineered for electronic chemicals and precision materials science. In these high-value sectors, CTAC functions as a critical phase transfer catalyst (PTC), structure-directing agent (SDA) for mesoporous silica and nanoparticle synthesis, and specialized electrolyte additive in wet processing chemicals.

Cetyltrimethylammonium Chloride Application
The amphiphilic structure and cationic nature of Cetyltrimethylammonium Chloride provide versatile functionality across advanced industrial and high-tech applications:
A. Electronic Chemicals & Advanced Materials Synthesis
Structure-Directing Agent (SDA): Widely utilized as a supramolecular template in the synthesis of mesoporous silica (e.g., MCM-41), gold nanorods, and structured ceramic nanomaterials used in microelectronics.
Wet Processing & Etching Additives: Serves as a charge-modifying surfactant in specialized wet chemical cleaning and etching formulations for semiconductor wafers, aiding in surface tension reduction and particle removal.
Phase Transfer Catalysis (PTC): Facilitates nucleophilic substitution and alkylation reactions between immiscible aqueous and organic phases in high-purity chemical synthesis.
B. Industrial Emulsification & Chemical Formulations
Polymerization & Emulsion Stabilization: Functions as a primary cationic emulsifier in latex polymerization, silicone emulsions, and industrial asphalt coatings.
Softening & Anti-Static Agent: Used as an effective antistatic coating for textiles, synthetic fibers, and specialized paper manufacturing.
C. Personal Care & Specialty Formulations
Hair & Skin Conditioning: Acts as a conditioning agent and hair rinse additive, neutralizing negative electrostatic charges on keratin surfaces to improve feel and wet combability.
Certifications & Regulatory Compliance
To support compliant international logistics and technical integration across European, American, and Asian markets, our production facilities and supply chain workflows adhere to recognized international standards:
ISO 9001:2015 Quality Management System: Certified quality frameworks governing raw material sourcing, synthesis, and lot-to-lot batch consistency.
ISO 14001:2015 Environmental Management System: Sustainable chemical processing protocols focused on environmental safety and emission reduction.
GHS & SDS Compliance: Safety Data Sheets (16 sections) compiled in full accordance with UN GHS guidelines, available in multiple language formats.
REACH Compliance Support: Complete technical documentation and registration dossiers supporting lawful importation into the European Single Market.
Dangerous Goods (DG) Packaging Compliance: Certified UN-rated packaging protocols (HDPE drums, IBC totes, and fiber drums) designed to ensure safe maritime and land transport of hazardous chemical cargo.
At SD Look Chemical, every batch of Cetyltrimethylammonium Chloride undergoes mandatory multi-parameter laboratory testing prior to release. Our internal testing protocols verify both active substance content and trace impurity thresholds.
Typical Certificate of Analysis (COA) Specifications:
Appearance: Clear solution (aqueous) or White powder (high-purity solid) (Conforms / Visual)
Active Content (Assay): 29.0 – 31.0 % (Liquid Grade) or ≥ 98.0 % (Solid High-Purity Grade) (Two-Phase Titration / HPLC)
Free Amine & Amine Hydrochloride: ≤ 1.5 % (Acid-Base Titration)
pH (10% aqueous solution): 6.0 – 8.5 (pH Potentiometry)
Moisture Content: ≤ 2.0 % (Solid Grade) (Karl Fischer Titration)
Color (APHA / Hazen): ≤ 50 (Liquid Grade) (Colorimetry)
Iron (Fe) & Trace Heavy Metals: ≤ 5 ppm (ICP-MS / Atomic Absorption)
Two-Phase Epton Titration / HPLC: Quantifies the exact active cationic quaternary ammonium content to guarantee precise stoichiometry in downstream formulations.
Acid-Base Titration for Free Amines: Measures unreacted tertiary amines, ensuring minimal residual impurities that could interfere with sensitive chemical reactions.
Karl Fischer Coulometric Titration: Accurately measures moisture levels in solid CTAC grades, ensuring stability for water-sensitive catalytic applications.
ICP-MS Heavy Metal Analysis: Critical for customers in electronic chemicals and nanomaterials, controlling trace metal contamination (such as Fe, Cu, Ni) down to sub-ppm levels.
Retained Batch Samples: Samples from every commercial dispatch are stored in controlled climate archives for up to 24 months to ensure complete post-delivery traceability.
FAQ
A: We offer standard commercial aqueous solutions (typically 30% active content), as well as high-purity solid powder grades (Assay ≥98.0%). Custom concentrations or refined grades with stricter trace metal specifications for electronic chemicals are available upon technical request.
Q2: What precautions should be taken regarding temperature and storage for CTAC aqueous solutions?
A: Cetyltrimethylammonium Chloride aqueous solutions (such as 30% concentration) may undergo reversible clouding or crystallization at lower ambient temperatures (below 15°C). This is a physical phase behavior and does not impact product quality. Gentle warming and agitation will restore the liquid to a clear, homogeneous state. Store in sealed containers away from direct sunlight and strong oxidizers.
A: Yes. We provide sample packages (ranging from 100g to 1kg) for qualified lab testing and customer trial validation. Our R&D and quality control team in Jinan can perform additional testing parameters (such as specific metal ion limits or color specifications) according to your process requirements.
A: Commercial shipments are packed in UN-approved HDPE drums (200kg) or IBC totes (1000kg) for liquid grades, and UN-rated fiber drums for solid grades. Each shipment is accompanied by a batch-specific Certificate of Analysis (COA), GHS-compliant Safety Data Sheet (SDS), and UN packaging compliance documentation for seamless customs clearance.
