Structural formula
1.Product Property
OE-35 is a pale-yellow to colorless liquid, fully miscible with water. It exhibits rapid wetting, high alkali, acid and oxidant stability, low foaming and good compatibility with cationic, anionic and non-ionic auxiliaries. The product remains clear over a wide temperature range and shows no phase separation under normal storage.
2.Technical Norm
| Parameter | Specification |
| Appearance (25 °C) | Pale-yellow to colorless liquid |
| pH (1 % aq.) | 6.5–7.5 |
| Hydroxyl value | 192–202 mg KOH g⁻¹ |
| Penetration (4 g L⁻¹, 25 °C) | ≤ 5 s |
| Water content | ≤ 0.5 % |
| Active content | ≥ 99 % |
3.Application Scope and Usage
OE-35 is used as a high-efficiency penetrant in textile pretreatment (scouring, bleaching, mercerizing) and in dyeing baths for reactive, disperse and vat dyes, promoting level uptake at 0.5–2 g L⁻¹. In leather processing it acts as a wetting and degreasing agent; in household and industrial cleaners it boosts soil removal at 0.2–1 g L⁻¹. The product is suitable for low-temperature processes and may be combined with enzymes, alkalis or peroxide without loss of activity.
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) with sealed screw caps. Store in a cool, dry, ventilated warehouse at 5–35 °C, away from strong acids and oxidizers. Keep drums tightly closed; slight layering may occur at low temperature but disappears after gentle stirring. Shelf life: 24 months from manufacture.
