Isooctanol Penetrant OE-35 is a nonionic surfactant with isomeric alcohol polyoxyethylene ether as the active ingredient, specifically designed for high-speed and efficient industrial penetration needs. It is widely used in textile printing and dyeing, leather chemicals, metal cleaning, pesticide synergists, papermaking, and daily chemicals.

Detailed Description

Isooctanol Penetrant OE-35 (CAS No.: 68439-51-0), chemical name isooctanol polyoxyethylene (35) ether, also known as 2-ethylhexanol polyoxyethylene ether, polyoxyethylene isooctyl ether, etc. This product belongs to the nonionic surfactant category and is produced and supplied by Haian Guoli Chemical Co., Ltd.

This product plays a key role in multiple industrial fields due to its excellent instant wetting ability, broad chemical compatibility, and low-foaming characteristics. Its core advantages include: rapid penetration and wetting (quickly wets various fibers and solid surfaces upon contact), resistance to acids, alkalis, and hard water (maintains stable chemical activity in different pH environments), low foam and easy rinsing (exhibits low foam tendency at room temperature and in elevated temperature applications), efficient emulsification and degreasing (shows excellent oil removal performance even at low temperatures), and good compounding synergy with nonionic, anionic, and cationic auxiliaries.

Main Uses

Isooctanol Penetrant OE-35 has a wide range of applications, mainly including the following six areas:

1. Textile Printing and Dyeing Pretreatment Penetrant: Used in desizing, scouring, bleaching, and mercerizing pretreatment processes for cotton, linen, and blended fabrics. It quickly wets the fibers and penetrates deep into the fabric interior, helping to remove impurities and natural by-products, improving capillary effect and whiteness, and laying a foundation for subsequent dyeing and printing.

2. Leather Chemical Penetrating and Degreasing Agent: Applied in wet processes such as soaking, degreasing, and tanning, accelerating the migration of water and chemicals into the deep layers of leather fibers, efficiently emulsifying and removing natural oils, improving leather softness and yield.

3. Metal Surface Cleaner: Used with acidic or alkaline cleaning agents, it quickly spreads over micro-pores and gaps on metal surfaces, driving cleaning agents into stubborn oil stains, rust, and carbon deposits underneath, achieving rapid stripping and cleaning, especially suitable for deep cleaning of precision parts.

4. Pesticide Synergist Adjuvant: Applied in pesticide suspension concentrates, soluble concentrates, and other formulations. It significantly reduces the surface tension of the spray solution, promoting rapid spreading and penetration of the liquid on plant leaves, stems, and target organism surfaces, reducing runoff and evaporation, and increasing the deposition and bioavailability of active ingredients.

5. Papermaking Penetration Auxiliary: In pulping, cooking, deinking, or coating processes, it promotes rapid entry of chemical solutions into fiber cell walls, accelerating reactions or dispersion, improving pulp bleaching efficiency, uniform sizing agent penetration, and coating adhesion.

6. Daily Chemical and Detergent Penetrant: Added to laundry detergents, hard surface cleaners, and other formulations, it helps active cleaning ingredients penetrate the interface between dirt and the substrate, breaking down stubborn stains, shortening soaking time, and enhancing deep cleaning effects.

Safety and Environmental Information

This product is not a hazardous substance, and its GHS classification indicates it is non-hazardous. Acute oral toxicity in rats LD50 > 5,000 mg\/kg, classified as low toxicity. It is non-irritating to skin (primary irritation index < 0.5). Eye contact may cause slight irritation but is fully reversible within 72 hours. It has good biodegradability (OECD tests show ready biodegradability) and low toxicity to aquatic organisms (fish 96-hour LC50 > 100 mg\/L).

Precautions

  • Operational Protection: Wear chemical safety goggles and nitrile gloves during operation. Ensure good ventilation in the working area and avoid inhaling vapors or mists.
  • Storage Conditions: Store in a cool, dry, well-ventilated warehouse. Temperature should be maintained between 5–35°C. Seal containers promptly after each use to avoid prolonged exposure to humid air or extreme low temperatures, preventing moisture absorption or freezing.
  • Emergency Treatment: In case of eye contact, rinse with flowing clean water for at least 15 minutes and seek medical attention promptly. For skin contact, wash thoroughly with soap and clean water for at least 10 minutes. If spilled, absorb and collect with inert materials such as sand or vermiculite.
  • Incompatibilities: Store separately from incompatible substances such as strong acids and strong oxidizers to avoid reactions.
  • Packaging Specifications: Conventionally packaged in clean plastic drums or IBCs. Custom packaging solutions can be provided according to customer requirements.
