Dimethyl(dioctadecyl)azanium chloride

Dimethyl(dioctadecyl)azanium chloride is a quaternary ammonium compound with the molecular formula C38H80ClN and CAS number 107-64-2. This cationic surfactant has a molecular weight of 586.5 g/mol and consists of a nitrogen atom bonded to two methyl groups and two long octadecyl (C18) chains, with chloride as the counterion. It belongs to the family of long-chain quaternary ammonium salts commonly used in industrial applications.

Dimethyl(dioctadecyl)azanium chloride is typically a white to off-white solid or waxy substance at room temperature due to its long alkyl chains. The compound has amphiphilic properties, meaning it contains both hydrophilic (quaternary ammonium head) and lipophilic (long alkyl chains) portions. It exhibits surface-active properties and can form micelles in aqueous solutions. The substance is generally soluble in polar solvents and demonstrates typical quaternary ammonium salt characteristics.

Dimethyl(dioctadecyl)azanium chloride is primarily used as a cationic surfactant and antimicrobial agent in various industrial applications. It serves as a biocide, disinfectant, and preservative in formulations. The compound is commonly employed in fabric softeners, hair conditioning products, and industrial cleaning formulations. Its quaternary ammonium structure makes it effective for surface modification, antistatic treatments, and as an emulsifier in specialized chemical processes.

Dimethyl(dioctadecyl)azanium chloride must be handled with extreme caution due to its Eye Dam. 1 classification. Always wear chemical-resistant gloves, safety goggles or face shield, and protective clothing when handling this substance. Ensure adequate ventilation and avoid creating dust or aerosols. Never touch or rub eyes with contaminated hands. Work in well-ventilated areas and use appropriate engineering controls to minimize exposure risks.

Dimethyl(dioctadecyl)azanium chloride should be stored in tightly closed, original containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers sealed when not in use to prevent moisture absorption and contamination. Store away from incompatible materials and ensure proper labeling according to GHS requirements. Due to its aquatic toxicity classification, prevent any spillage that could reach water systems or soil.

In case of eye contact with dimethyl(dioctadecyl)azanium chloride, immediately flush with plenty of water for at least 15 minutes and seek immediate medical attention due to its severe eye damage potential. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air immediately. Remove contaminated clothing and wash before reuse. Never induce vomiting if ingested. Always consult a physician and provide the safety data sheet.

Dimethyl(dioctadecyl)azanium chloride must be disposed of according to local, national, and international waste regulations due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1). Contact licensed waste disposal companies for proper treatment and disposal. Never discharge into water systems, sewers, or soil. Contaminated packaging should also be treated as hazardous waste. Consult local environmental authorities for specific disposal requirements in your region.

Dimethyl(dioctadecyl)azanium chloride is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. This classification requires appropriate packaging, labeling, and documentation according to ADR regulations. Use UN-approved packaging and ensure proper hazard labels are displayed during transport. Drivers must carry appropriate transport documents and emergency response information. Consult current ADR regulations for specific packaging and documentation requirements.

Dimethyl(dioctadecyl)azanium chloride is subject to multiple European regulations including REACH registration requirements and CLP classification (Eye Dam. 1; Aquatic Acute 1; Aquatic Chronic 1). It requires GHS05 and GHS09 pictograms and 'Danger' signal word on labels. The substance is not currently listed as an SVHC under REACH. Users must comply with occupational safety regulations and environmental protection laws due to its hazardous properties.
