CAS: 68439-39-4
Alias: OEP-70, Alkali-stable wetting agent, Phosphate-ester penetrant
Molecular formula:C10H23O5P
1.Propiedad del producto
OEP-70 is a viscous, pale-yellow to amber liquid that dissolves readily in water above 40 °C. It withstands >200 g L⁻¹ NaOH, 30 % H₂O₂ and high temperatures without hydrolysis. The product offers rapid wetting (<5 s in 150 g L⁻¹ NaOH at 60 °C), low foam, excellent emulsification and dispersion of oils and pigments, and stabilises hydrogen peroxide in bleaching baths.

3.Ámbito de aplicación y uso
OEP-70 is the key ingredient in preparation of high-alkali scouring agents, mercerising penetrants and one-bath desize-scour-bleach formulations for cotton and blends. It is blended into detergents, degreasers and emulsifiers for metal cleaning, leather degreasing and industrial hard-surface cleaners. Typical dosage: 2–8 % in alkaline scours, 1–3 % in emulsifiable concentrates. Heat to 40 °C to dissolve before blending with other auxiliaries.
4.Embalaje y almacenamiento
Supplied in 50 kg new HDPE drums (Ø 380 × 480 mm) with screw cap and tamper seal. Store in a cool, ventilated warehouse at 5–35 °C, away from strong acids and oxidisers. Keep containers tightly closed; avoid temperatures below 5 °C to prevent crystallisation. Shelf life: 24 months from manufacture under recommended conditions.
