Oil & Gas: Gas Sweetening & Carbon Capture

Standard aqueous solution used in the "Amine Scrubbing" process. It removes acidic contaminants (H,S and COz) from natural gas and refinery off-gases through a reversible chemical reaction, ensuring the gas meets pipeline specifications and environmental standards

Beauty & Personal Care: Surfactant Precursor

To Manufacture Diethanolamides (like Cocamide DEA), which act as foam stabilizers, viscosity builders, and emulsifiers in shampoos, liquid soaps, and bubble baths. Serves as a mild pH adjuster in various skin care products

Agrochemicals: Glyphosate Synthesis

Intermediate in the production of Glyphosate. Assists in the formation of the salt-based active ingredient, ensuring high water solubility and leaf penetration

Stroage Stability

Hygroscopic and sensitive to light and air. DEA has a freezing point of 28°C (82°F); in cooler climates, it will solidify in the drum and may require "hot room" storage.

Storage Section

Store in a dry, well-ventilated area. Use stainless steel or high-density polyethylene (HDPE) tanks. To prevent discoloration, store under a Dry Nitrogen Blanket.
