Category: Surfactants
| Purity | Technical Grade ≥90% (balance primarily stearyl alcohol, polyethylene glycols, and unreacted amine), |
| Molecular Formula | C₂₆H₅₅NO₅ |
| Molecular Weight | 461.72 |
| Appearance | White to off-white waxy solid or paste at room temperature; clear to hazy liquid when warmed |
| Packaging | 50g/100g/500g/1kg/plastic bottle or aluminum foil bag (for research); 25kg/50kg/plastic drum or fiber drum; 200kg/steel drum with PTFE liner; custom packaging for bulk orders |
| Testing Indicators | Appearance — Visual inspection; Identification — FTIR (OH, C-O-C, C-N stretches) or NMR (¹H, ¹³C); Purity — GC-FID (high-temperature column) or HPLC (C18 column, ELSD or CAD detection); Amine value — Potentiometric titration (perchloric acid in non-aqueous medium); Hydroxyl value — Acetylation or phthalation followed by titration; Water content — Karl Fischer titration; Color — Gardner color scale (molten sample); Melting point (or softening point) — Capillary or dropping point method; pH (1% aqueous dispersion) — Potentiometry; Residual ethylene oxide — GC headspace; Residual stearyl alcohol — GC; Heavy metals — ICP-MS. |
| Storage Notes | Stored in a tightly sealed container in a cool, dry, well-ventilated area, protected from light and moisture; away from strong oxidizers, strong acids, and heat sources; keep container closed to prevent absorption of CO₂ (tertiary amine may react with CO₂ to form carbonate salts); may solidify at low temperatures – gentle warming (40–50°C) with stirring to re-liquefy before use. |

Used as a non-ionic or cationic surfactant (depending on pH) in personal care products (conditioners, emulsifiers, antistatic agents); as an emulsifier in industrial formulations (coatings, polishes, lubricants); as a wetting agent and dispersant; in textile processing as a softening and antistatic agent; in metalworking fluids as a corrosion inhibitor; as a chemical intermediate for the synthesis of quaternary ammonium compounds (e.g., ethoxylated stearyl amine derivatives).
