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 features two long octadecyl (C18) alkyl chains attached to a nitrogen atom, along with two methyl groups and a chloride counterion. It belongs to the class of dialkyl dimethyl ammonium chlorides, which are widely used as surfactants and antimicrobial agents in various industrial applications.

Dimethyl(dioctadecyl)azanium chloride appears as a white to off-white waxy solid or paste at room temperature due to its long alkyl chains. The compound has a molecular weight of 586.5 g/mol and exhibits typical quaternary ammonium salt characteristics. It is soluble in polar solvents like water and alcohols when heated, and shows surface-active properties due to its amphiphilic structure. The compound is odorless or has a faint characteristic odor typical of quaternary ammonium compounds.

Dimethyl(dioctadecyl)azanium chloride serves primarily as a cationic surfactant and antimicrobial agent in industrial formulations. It is commonly used in fabric softeners, hair conditioning products, and personal care formulations due to its conditioning properties. The compound also finds applications as a disinfectant and preservative in various industrial processes, antistatic agent in textile processing, and as an emulsifier in specialized chemical formulations requiring cationic surface activity.

Dimethyl(dioctadecyl)azanium chloride must be handled with extreme caution as it causes serious eye damage (Eye Dam. 1). Always wear chemical safety goggles, protective gloves, and protective clothing when handling this substance. Ensure adequate ventilation in the work area and avoid generating dust or aerosols. Never touch or rub eyes with contaminated hands or gloves. Use appropriate engineering controls such as local exhaust ventilation, and establish proper hygiene procedures including thorough handwashing after handling.

Dimethyl(dioctadecyl)azanium chloride should be stored in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly closed when not in use and protect from moisture to prevent caking or degradation. Store away from oxidizing agents and strong acids or bases. Maintain storage temperatures below 40°C to prevent melting and ensure easy handling. Use appropriate containment measures to prevent environmental release, given its aquatic toxicity classification (Aquatic Acute 1, Aquatic Chronic 1).

Dimethyl(dioctadecyl)azanium chloride contact requires immediate action due to its eye-damaging properties. For eye contact, immediately flush with large amounts of water for at least 15 minutes, holding eyelids open, and seek immediate medical attention. For skin contact, wash thoroughly with soap and water. If ingested, rinse mouth with water and seek medical advice. For inhalation of dust, move to fresh air. Do not induce vomiting if swallowed. Always seek professional medical attention for any significant exposure.

Dimethyl(dioctadecyl)azanium chloride disposal must comply with local and national hazardous waste regulations due to its environmental hazard classification. The substance should never be discharged to sewers or the environment given its aquatic toxicity (Aquatic Acute 1, Aquatic Chronic 1). Arrange disposal through licensed hazardous waste contractors who can handle quaternary ammonium compounds appropriately. Small quantities may be treated through approved chemical waste incineration facilities. Always consult local environmental authorities for specific disposal requirements.

Dimethyl(dioctadecyl)azanium chloride is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III, indicating it presents a relatively lower but significant transport hazard. Packages must be properly labeled with appropriate hazard markings and transport documents must be completed according to ADR regulations. Use appropriate packaging that meets UN specification requirements for Class 9 substances. Ensure proper segregation from incompatible materials during transport and follow specific loading and handling procedures for miscellaneous dangerous goods.

Dimethyl(dioctadecyl)azanium chloride is subject to CLP regulation requirements due to its hazard classification (Eye Dam. 1, Aquatic Acute 1, Aquatic Chronic 1) and must display appropriate GHS05 and GHS09 pictograms with 'Danger' signal word. Under REACH regulation, it requires registration if imported or manufactured above one tonne annually. The substance is not currently listed as SVHC. Additional restrictions may apply regarding aquatic discharge due to its environmental hazard profile, and industrial hygiene regulations apply given its eye damage potential.
