What is Ethoxylated stearylamine?
Ethoxylated stearylamine (CAS 26635-92-7), also supplied under the designation RY 130T2, is a cationic surfactant derived from the ethoxylation of stearylamine.
Where is Ethoxylated stearylamine used?
- Textile processing: softening and antistatic agent that improves fabric handle and reduces static charge buildup during finishing
- Agricultural formulations: adjuvant in herbicide and pesticide concentrates
- Industrial and institutional cleaning: degreasing and soil dispersion for hard surfaces and metal parts
- Personal care and cosmetics: emulsion stability and conditioning in rinse-off products
- It functions as an emulsifier, dispersant, and rheology modifier.
Good to know: Grades vary by ethylene oxide content, commonly expressed as moles of EO per mole of amine, which determines HLB value and application suitability.
Commercial specifications
- Bulk packaging: drums and IBCs
