Applications
1.Latex Stabilizer For Emulsion Systems:Ethoxylated cocoamine (CAS 61791-14-8) is a fatty amine ethoxylate that stabilises latex and emulsion systems, helping keep polymer particles dispersed, control particle size and reduce coagulum formation.
2.Antistatic Performance:The ethoxylated fatty amine structure provides antistatic function, so it is used to control static charge in plastics, synthetic fibres and surface coatings, cutting dust pickup and static-related handling problems.
3.Textile Dyeing And Fibre Processing:Used as a levelling agent it adsorbs on fibre surfaces to slow dye uptake and promote uniform shade, and it also works as an emulsifier, scouring aid and softener in textile and synthetic fibre processing.
4.Corrosion Inhibition And Lubricity:The molecule brings corrosion inhibiting and rust preventive performance together with lubrication, supporting use in metalworking fluids, plating bath additives and protective coating formulations.
5.Agrochemical And Industrial Emulsifier:The ethoxylated amine wets and disperses oils and active ingredients, supporting use in agrochemical emulsifier blends, pigment and coating dispersions and other industrial surfactant systems.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
