Octadecyl Trimethyl Ammonium Bromide (1831-Br/OTAB)

CAS 1120-02-1

Octadecyl Trimethyl Ammonium Bromide (CAS 1120-02-1) is a high-purity cationic quaternary ammonium salt widely used as a phase transfer catalyst, asphalt emulsifier, and textile antistatic agent. This white crystalline powder exhibits excellent solubility in hot water and ethanol, making it ideal for applications in organic synthesis, cosmetic formulations such as hair conditioners, and industrial processes including organoclay modification and corrosion inhibition. With a typical assay of ≥99% and low free amine content, it ensures consistent performance in both research and manufacturing environments.

>> Main Uses

Octadecyl Trimethyl Ammonium Bromide (1831-Br/OTAB, CAS 1120-02-1) is primarily used as a high-performance asphalt emulsifier, enabling the production of stable emulsions for road construction and waterproofing coatings. It serves as a key modifying agent for organic bentonite, transforming it into effective rheological additives that control viscosity in oil-based drilling fluids and lubricants. The compound functions as a reliable antistatic agent for synthetic fibers, including nylon and polyester, reducing static charge accumulation during processing and end-use. In textile manufacturing, it acts as a softening agent and anti-glowing treatment for specialized fabrics such as nylon parachute materials. Additionally, it finds application as a corrosion inhibitor in metalworking fluids and as a dispersant in pigment and dye formulations.
