【Type】Nonionic
1. Product Property
SF is a pale-yellow to light-yellow oily liquid, fully miscible with water and common organic solvents. It remains fluid at 0 °C and does not form viscous gels on dilution. Its low-foaming profile, rapid wetting (≤ 70 s sinking at 0.1 %) and high active content (≥ 99 %) make it ideal for high-speed processes where foam control is critical.
2. Quality Standard
| Parameter | Specification |
| Appearance (25 °C) | Pale-yellow to light-yellow oil |
| pH (1 % aqueous) | 5.0–7.0 |
| Penetration (0.1 % aq.) | ≤ 70 s, ≥ 100 % vs JFC |
| Active content | ≥ 99 % (wt) |
| Freeze point | < 0 °C |
| Water content | ≤ 1 % |
3. Application Scope and Usage
SF is formulated for low-foam scouring, desizing and bleaching of all fibre types. It accelerates oil removal, prevents redeposition and leaves fabrics clean without excessive foam. In synthetic-fibre oil preparations it acts as an emulsifier and anti-static component. SF is also used as a detergent and emulsifier in metal cleaning, paper processing and household hard-surface cleaners. Typical dosage: 0.2–2 g L⁻¹ in textile baths; 1–5 % in oil concentrates.
4. Package and Storage
Supplied in 200 kg epoxy-lined steel drums (Ø 585 × 890 mm) or 50 kg HDPE drums (Ø 380 × 480 mm). Store in a cool, dry, well-ventilated warehouse at 0–35 °C, away from strong acids and oxidizers. Keep drums tightly closed. Shelf life: 24 months from manufacture under recommended conditions.
