Isooctanol penetrant OE-35 is a nonionic surfactant with isomeric alcohol polyoxyethylene ether as the active ingredient. Its core features include ultra-fast wetting and penetration, resistance to acids, alkalis, and hard water, low foaming and easy rinsing, efficient emulsification and degreasing, and excellent compounding synergy.

The product is designed for high-speed, efficient industrial penetration needs and plays a key role in textiles, leather, metal treatment, pesticide synergists, and other industries. Its molecular structure provides outstanding instantaneous wetting ability, quickly wetting various fibers and solid surfaces upon contact, strongly carrying the working fluid into micropores and crevices, effectively shortening process time and improving final product quality.

The product maintains stable chemical activity in treatment environments with different pH values, showing excellent resistance to high-concentration electrolytes and hard water ions. Therefore, it can reliably exert its penetration effect under acidic, alkaline, and hard water conditions. At the same time, it exhibits a low foaming tendency in both room temperature and heated applications, effectively reducing foam interference with mechanical operations and significantly lowering subsequent rinsing difficulty and water consumption. It is an industrial auxiliary agent that combines high performance with operational convenience.

In addition, OE-35 has good compounding synergy and is compatible with nonionic, anionic, and cationic auxiliaries. It can be used as a synergistic component to enhance the spreading and adsorption capacity of the formulation. In terms of safety and environmental protection, this product is not classified as a hazardous substance, is non-irritating to the skin, has good biodegradability, and meets basic requirements for being environmentally friendly.

Application Recommendations

With its five core characteristics, isooctanol penetrant OE-35 is widely applicable in various industrial fields:

  • Textile Printing and Dyeing: Used in pretreatment processes such as desizing, scouring, bleaching, and mercerizing of cotton, linen, and blended fabrics. As a high-efficiency penetrant, it significantly improves capillary effect and whiteness, laying a uniform foundation for subsequent dyeing and printing.
  • Leather Chemicals: Applied in soaking, degreasing, and tanning processes to accelerate the migration of water and chemicals into deep layers of leather fibers, efficiently emulsify and remove natural oils, while maintaining a fine grain surface, improving leather softness and yield rate.
  • Metal Surface Treatment: Used with acid pickling or alkaline cleaning agents, it quickly spreads into micropores and crevices on metal surfaces, stripping and removing stubborn dirt such as cutting fluids, rust inhibitors, and carbon deposits, especially suitable for deep cleaning of precision parts.
  • Pesticide Synergist Adjuvant: Applied in formulations such as suspension concentrates and soluble concentrates, significantly reducing the surface tension of the spray liquid, improving retention and systemic translocation efficiency on hydrophobic leaf surfaces, reducing runoff and evaporation, and enhancing control efficacy.
  • Paper Industry: Used as a cooking or deinking penetration aid to promote chemical penetration, while also playing an auxiliary role in pitch control, improving pulp bleaching efficiency and sizing uniformity.
  • Daily Chemical and Industrial Cleaning: Suitable for multi-purpose hard surface cleaners and degreaser formulations, helping active ingredients penetrate the interface between dirt and substrate, breaking down stubborn stains, shortening soaking time, and enhancing deep cleaning effects.

Precautions

  • Storage temperature should be maintained between 5–35°C, stored in a cool, dry, and well-ventilated warehouse, keep container sealed, away from fire, heat sources, and direct sunlight.
  • Seal the container promptly after each use to avoid prolonged exposure to humid air or extremely low temperatures, preventing moisture absorption or freezing.
  • When handling, it is recommended to wear chemical safety goggles and nitrile gloves, and ensure good ventilation in the operation area.
  • Eye contact may cause mild irritation (fully reversible within 72 hours). If accidentally get into eyes, rinse immediately with running water for at least 15 minutes and seek medical attention.
  • Store separately from incompatible substances such as strong acids and strong oxidizers to avoid reactions from mixing.
  • For specific safety operation guidelines and ecotoxicological data, refer to the Material Safety Data Sheet (MSDS).
