When using alkali-resistant penetrant OEP-70, special attention should be paid to safety protection, adaptability to high-alkali environments, and storage conditions to ensure operator safety and full performance of the product.
Detailed Description
Alkali-resistant penetrant OEP-70 (isooctanol polyoxyethylene ether phosphate) is an anionic surfactant specially designed for high-alkali process environments. Its core advantage is achieving deep penetration within seconds while maintaining excellent solubility and activity in high-concentration alkali baths. However, as a chemical auxiliary, it must be handled in compliance with relevant safety regulations to avoid potential health risks.
This product may cause mild skin and eye irritation, is harmful if swallowed, and prolonged or repeated exposure can lead to skin defatting and dryness. Therefore, operators must wear chemical-resistant protective gloves, safety goggles, and protective clothing, and maintain good ventilation in the workplace. In case of accidental contact, rinse immediately with plenty of water and seek medical attention if necessary. Detailed safety information must refer to the official Safety Data Sheet (SDS) provided by the supplier.
In terms of performance, OEP-70 exhibits excellent hard water tolerance, preventing calcium soap precipitation in hard water environments and reducing equipment scaling risk. Its low-foaming property makes it suitable for circulating spray and high-speed processing equipment. However, product storage temperature should be controlled at 5～40°C to avoid freezing and stratification, which could affect performance.

Application Recommendations
OEP-70 is suitable for various high-alkali process scenarios. It is recommended to adjust the dosage based on the specific process:
- Textile Pretreatment: Used as a high-efficiency penetrant in alkali-oxygen one-bath pretreatment, cold pad-batch process, and mercerizing process for cotton and blended fabrics, added directly.
- Scouring and Bleaching: In high-alkali scouring and oxygen bleaching processes, it helps chemicals penetrate evenly, reducing processing marks.
- Pulp and Paper: Used as a penetration aid in pulping and waste paper deinking processes, promoting chemical penetration and ink separation.
- Leather Processing: Used as a high-efficiency degreasing agent and penetrant to improve treatment uniformity.
- Industrial Cleaning: Used in metal surface treatment and alkaline cleaning formulations to enhance degreasing and defatting effects.
Precautions
- Personal Protection: Must wear chemical protective gloves and goggles during operation to avoid direct contact with skin and eyes. Wash hands and any potentially exposed areas thoroughly after operation.
- Ventilation Requirements: The workplace should be well-ventilated to avoid inhaling vapors or mists.
- Storage Requirements: Store in a cool, dry, well-ventilated warehouse, keeping containers tightly closed. Control temperature at 5～40°C to avoid freezing and product stratification. Keep away from heat sources, ignition sources, strong oxidizers, strong acids, and strong alkalis.
- Emergency Treatment: For skin contact, rinse with plenty of water and soap for at least 15 minutes; for eye contact, rinse continuously with running water for at least 15 minutes and seek medical attention; if ingested, do not induce vomiting and seek immediate medical attention.
- Spill Disposal: Small spills: absorb with inert material and transfer; large spills: contain to prevent entry into drains or water bodies, dispose of according to local regulations.
- Confirmation Before Use: Evaluate suitability under specific process conditions before actual use, and always refer to the official SDS provided by the supplier.
