Dimethyldecylamine

CAS: 1120-24-7

Overview

Dimethyldecylamine (CAS 1120-24-7 ) is a tertiary aliphatic amine used as a chemical intermediate and functional ingredient across cleaning, personal care, and textile processing industries.

Its primary commercial role is as a precursor to quaternary ammonium compounds and amine oxides, which are active components in surfactant and disinfectant formulations.

In home care and industrial cleaning, it serves as a building block for quats and amine oxide surfactants used in fabric softeners, hard surface cleaners, and disinfectant concentrates.

Personal care formulators use it to produce conditioning agents and foam boosters in shampoos, body washes, and rinse-off treatments for various consumer applications.

Textile and leather processors apply it in the synthesis of softening and antistatic agents that improve handle and reduce static buildup on finished fabrics during production.

In paper manufacturing, it contributes to surface-active formulations that aid fiber dispersion and wet-strength chemical systems to ensure high-quality output and durability.

Dimethyldecylamine is supplied as a clear to pale yellow liquid, typically at purities of 98–99% for technical and synthesis-grade applications for industrial use.

It is available in standard packaging including drums and IBC containers, with bulk quantities offered for industrial procurement and large-scale manufacturing requirements.
