The alkali-resistant penetrating agent OEP-70 (isooctyl alcohol polyoxyethylene ether phosphate potassium salt) is an anionic surfactant specially designed for high-alkali process environments. The phosphate ester group in its molecular structure endows the product with excellent alkali resistance stability, allowing it to maintain outstanding solubility and penetrating activity in strong alkali baths without precipitation or stratification. This property makes OEP-70 an ideal penetrating agent choice for key processes such as alkali-oxygen one-bath, cold pad-batch, and mercerizing in the textile printing and dyeing industry.
Beyond the textile field, OEP-70, with its rapid penetration and excellent wetting and spreading properties, has successfully expanded to multiple industrial sectors, including penetration aids in papermaking and pulping and waste paper deinking processes, degreasing and penetration treatment in leather processing, and alkaline cleaning agent formulations for industrial metal surfaces. This product integrates three major functions—penetration, alkali resistance, and hard water resistance—effectively simplifying the formulation system and reducing overall costs.
Furthermore, OEP-70 exhibits outstanding hard water tolerance and low foaming characteristics, preventing calcium soap precipitation in hard water environments, reducing the risk of equipment scaling, and adapting to circulating spray and high-speed processing equipment, further broadening its applicability in industrial applications.
| Industry | Process/Application | Functional Role |
|---|---|---|
| Textile Printing and Dyeing | Alkali-oxygen one-bath pretreatment, cold pad-batch process, mercerizing process | High-efficiency penetrating agent, promoting uniform chemical action |
| Textile Printing and Dyeing | High-alkali scouring and oxygen bleaching processes | Improving penetration and treatment uniformity |
| Papermaking and Pulping | Pulping penetration, waste paper deinking | Promoting chemical penetration and ink separation |
| Leather Processing | Degreasing, penetration treatment | Improving treatment efficiency and uniformity |
| Industrial Cleaning | Metal surface treatment, alkaline cleaning agent formulation | Enhancing oil and grease removal effect |
In textile pretreatment processes, OEP-70 is particularly suitable for alkali-oxygen one-bath processing of cotton and its blended fabrics. It is recommended to be added as a core component of the penetrating agent in the treatment bath, achieving deep penetration within seconds and significantly shortening the process time. For mercerizing processes, its excellent alkali resistance stability ensures continuous wetting and penetration in high-concentration caustic soda baths. In waste paper deinking processes, OEP-70 effectively promotes chemical penetration into fibers, accelerating ink stripping and separation. When used in combination in industrial alkaline cleaning agents, OEP-70 enhances the removal of oil stains on metal surfaces, while its low foaming property makes it suitable for high-pressure spray cleaning systems.
