Alkali-resistant penetrant OEP-70 is an anionic surfactant specially designed for high-alkali process environments. Its chemical component is isooctyl alcohol polyoxyethylene ether phosphate, integrating three core functions: rapid penetration, ultra-high alkali resistance, and excellent hard water resistance.

Detailed Description

Alkali-resistant penetrant OEP-70 (CAS: 68439-51-0), also known as isooctyl alcohol polyoxyethylene ether phosphate potassium salt or 2-ethylhexanol polyoxyethylene ether phosphate, is a high-performance anionic surfactant produced by Haian Guoli Chemical Co., Ltd. The product appears as a colorless to slightly yellow transparent viscous liquid, specially designed for harsh high-alkali process environments. It maintains excellent solubility and activity in strong alkali baths without precipitation or stratification, ensuring stable and reliable processing.

The most prominent feature of this product is its ability to achieve deep penetration within seconds, significantly shortening process time and improving production efficiency. At the same time, it has excellent wetting and spreading properties, quickly wetting fiber and substrate surfaces, promoting uniform distribution of the treatment solution, and effectively avoiding treatment marks. In addition, OEP-70 maintains high efficiency in hard water environments, with no risk of calcium soap precipitation, reducing equipment scaling, and has good low-foaming characteristics, suitable for circulating spray and high-speed processing equipment.

As a "multi-functional" additive, OEP-70 can effectively simplify formulations, reduce overall costs, and improve end-product quality. It is widely used in various industrial fields such as textile printing and dyeing pretreatment, papermaking pulping, leather processing, and industrial cleaning. It is an ideal choice for improving processing efficiency and uniformity.

Application Suggestions

Textile Printing and Dyeing: Suitable for alkali-oxygen one-bath pretreatment of cotton and its blended fabrics, cold pad-batch process, and mercerizing process, used as a high-efficiency penetrant. It is also applicable in high-alkali scouring and oxygen bleaching processes to improve the penetration and uniformity of chemicals. It is recommended to add it in the pretreatment liquor, with dosage depending on process conditions and alkali concentration.

Papermaking Industry: Used as a penetration aid in the pulping process and in waste paper deinking process, promoting chemical penetration and ink separation, improving pulp treatment efficiency.

Leather Processing: Used as a high-efficiency degreasing agent and penetrant, it can significantly improve leather processing efficiency and uniformity, suitable for various leather pretreatment processes.

Industrial Cleaning: Suitable for metal surface treatment and alkaline cleaning agent formulations, enhancing oil and grease removal effect, maintaining excellent cleaning performance even under hard water conditions.

Precautions

  • Harmful if swallowed. Avoid ingestion during operation.
  • May cause mild skin and eye irritation. It is recommended to wear chemical-resistant protective gloves and safety goggles.
  • Wash hands and other contacted areas thoroughly after operation. Avoid prolonged or repeated contact to prevent defatting and drying of the skin.
  • Store in a cool, dry, well-ventilated warehouse. The temperature should be controlled at 5~40°C. Avoid freezing to prevent product stratification.
  • Avoid mixing storage with strong oxidizers, strong acids, or strong alkalis.
  • In case of accidental contact with skin or eyes, rinse immediately with plenty of water for at least 15 minutes. Seek medical attention if necessary.
  • For detailed safety information, please refer to the Safety Data Sheet (SDS).
