Propyldiethanolamine

Propyldiethanolamine (CAS 6735-35-9) is a tertiary alkanolamine combining both amine and hydroxyl functionality, making it effective as a pH buffer, corrosion inhibitor, and emulsifier across industrial formulations.

N-Propyldiethanolamine is the recognized alternative designation buyers encounter in technical literature and supplier documentation. In metalworking fluids and cutting coolants, it buffers pH and inhibits ferrous and non-ferrous metal corrosion.

This chemical helps in extending fluid service life in various mechanical applications. Industrial and institutional cleaning formulations use it to emulsify oils and disperse soils while maintaining alkaline stability under dilution.

Water treatment programs incorporate it as a corrosion inhibitor and chelating agent to control scale and metal ion interference in recirculating systems. This ensures the longevity and efficiency of industrial water infrastructure.

Coatings and adhesive formulations employ it as a neutralizing amine for acid-functional resins. This application improves dispersion stability and substrate adhesion in modern waterborne systems used in manufacturing.

Propyldiethanolamine is supplied as a liquid, typically at high purity levels suited for industrial and specialty chemical applications. Technical grade is the standard commercial offering for most buyers.

Purity specifications are commonly in the 98–99%+ range depending on the specific supplier requirements. Packaging ranges from drums to intermediate bulk containers (IBCs) for large industrial volumes.
