Description

Dodecyltrimethylammonium Methyl Sulphate is a high-purity quaternary ammonium salt, widely recognized as a cationic surfactant and phase transfer catalyst. Its primary value lies in its ability to modify surfaces, stabilize emulsions, and facilitate reactions between immiscible phases, making it a critical component in advanced formulations. This compound is essential for industries requiring precise chemical intermediates, including specialty chemical synthesis, textile processing, and personal care product development.

Application

• As a cationic surfactant and emulsifying agent in personal care and cosmetic formulations.
• As a phase transfer catalyst (PTC) in organic synthesis, particularly for alkylation and displacement reactions.
• In the textile industry as a softening agent, antistatic agent, and dyeing auxiliary.
• As a biocide and disinfectant component in industrial and institutional cleaning products.
• For the preparation of clay modifiers and organoclays used in nanocomposites.
• As a corrosion inhibitor and additive in specialty coatings and oilfield chemicals.
• In biotechnology and molecular biology as a cell lysis and protein extraction reagent.
