Alkali-resistant penetrant OEP-70 (isooctyl alcohol polyoxyethylene ether phosphate) is a highly effective anionic surfactant with an effective content of 70.0±2.0%, appearing as a light yellow to yellow transparent viscous liquid, easily soluble in water. In actual use, it can be directly added to the working solution and stirred evenly, or pre-diluted with warm water (40~50°C) into a 10%~20% solution before dosing to facilitate rapid dispersion. This product maintains excellent solubility and activity in high-concentration alkali baths of 200~300g/L NaOH, with no precipitation or delamination, making it particularly suitable for high-alkali processes such as one-bath alkali-oxygen, cold pad-batch, and mercerizing.
According to technical parameters from the Guoli Chemical database, the penetration time of OEP-70 at a concentration of 5g/L on standard canvas is ≤5 seconds, and the critical micelle concentration (CMC) is 0.02%~0.06% (wt%), i.e., 0.2~0.6g/L can form effective micelles. This means that a very low dosage can achieve penetration and wetting effects. Actual usage can be adjusted upward based on alkali concentration, substrate type, and process requirements.

The following are reference dosages based on product performance and industry general experience (based on commercial raw liquid). The specific dosage should be determined through small-scale trials according to actual process conditions:
| Application Area | Process/Use | Reference Dosage (Commercial Raw Liquid) |
|---|---|---|
| Textile Pretreatment | One-bath alkali-oxygen for cotton and blended fabrics | 2~5 g/L |
| Textile Pretreatment | Cold pad-batch process | 3~8 g/L |
| Textile Pretreatment | Mercerizing penetrant | 3~5 g/L |
| Textile Scouring and Bleaching | High-alkali scouring and oxygen bleaching | 1~3 g/L |
| Leather Processing | Degreasing agent, penetrant | 1~5 g/L |
| Paper Pulping | Pulping penetration aid | 0.5~2 g/L |
| Paper Deinking | Waste paper deinking process | 0.5~2 g/L |
| Industrial Cleaning | Alkaline cleaning agent formulation component | 1~10 g/L (or 1%~5% of total formulation) |
Note: The above dosages are industry general reference values. The Guoli Chemical product database does not have official recommended dosage data for various processes. Users are advised to determine the optimal dosage through small-scale trials based on their own process conditions (alkali concentration, temperature, substrate type, equipment, etc.).
