Alkali-Resistant Penetrant OEP-70 is an anionic surfactant specially designed for high-alkali process environments, integrating rapid penetration, ultra-high alkali resistance stability, and excellent hard water tolerance, with CAS number 68439-51-0.

Detailed Description

Alkali-Resistant Penetrant OEP-70,chemical name Isooctyl Alcohol Polyoxyethylene Ether Phosphate (potassium salt), belongs to anionic surfactants. The product appears as a colorless to slightly yellow transparent viscous liquid, developed by Guoli Chemical as a high-performance additive specifically for high-alkali conditions in textile printing and dyeing, papermaking, leather processing, and industrial cleaning.

The core value of this product lies in its "multi-effect in one" — it not only does not precipitate or separate in strong alkaline baths but also achieves deep penetration within seconds, significantly shortening process time. Meanwhile, its excellent wetting and spreading properties ensure uniform distribution of the treatment solution, effectively avoiding treatment marks, and it features low-foam characteristics, making it suitable for circulating spray and high-speed processing equipment.

In hard water environments, OEP-70 maintains high activity without the risk of calcium soap precipitation, reducing equipment scaling issues, thereby simplifying formulation systems, lowering overall costs, and improving the quality of end products.

Application Suggestions

Textile Printing and Dyeing: Suitable for alkali-oxygen one-bath pretreatment, cold pad-batch process, and mercerizing of cotton and blended fabrics, used as a high-efficiency penetrant; also applied in high-alkali scouring and oxygen bleaching processes to enhance chemical penetration and treatment uniformity.

Papermaking Industry: Used as a penetration aid in pulping and deinking of waste paper, promoting chemical penetration and ink separation.

Leather Processing: Used as an efficient degreasing agent and penetrant to improve processing efficiency and uniformity.

Industrial Cleaning: Applicable for metal surface treatment and alkaline cleaning formulations to enhance oil and grease removal effect.

Precautions

  • Harmful if swallowed, may cause mild skin and eye irritation, prolonged or repeated contact may cause skin defatting and dryness.
  • When handling, it is recommended to wear chemical-resistant protective gloves, safety goggles, and protective clothing, and maintain good ventilation in the work area.
  • Storage temperature should be controlled at 5~40℃, avoid freezing to prevent product separation.
  • Avoid mixing with strong oxidizers, strong acids, and strong alkalis; keep containers tightly closed.
  • In case of accidental contact, rinse immediately with plenty of water; refer to the Safety Data Sheet (SDS) for detailed safety information.
