Isooctanol penetrant OE-35 is a non-ionic surfactant with isomeric alcohol polyoxyethylene ether as the active ingredient, widely used in six major industries including textile printing and dyeing, leather chemicals, metal surface treatment, pesticide synergism, papermaking, and daily chemical cleaning. It covers more than ten key processes such as desizing, scouring, degreasing, pickling, and application synergism.

Detailed Description

Isooctanol penetrant OE-35 (CAS number: 68439-51-0), with its extremely fast wetting and penetrating ability, excellent resistance to acids, alkalis, and hard water, and low-foaming, easy-rinsing characteristics, has become an efficient auxiliary agent in industrial pretreatment and cleaning fields. Its core mechanism lies in significantly reducing the surface tension of the working solution, quickly wetting various solid surfaces such as fibers, leather, and metal upon contact, and effectively carrying active ingredients into micropores and gaps, thereby greatly shortening process time and improving treatment uniformity.

Another major advantage of this product is its wide chemical compatibility: it has good compounding synergy with non-ionic, anionic, and cationic auxiliaries, and can be used as a synergistic component to enhance the spreading and adsorption capacity of the formulation. At the same time, its low toxicity, non-irritating nature to the skin, and good biodegradability give it significant compliance advantages in industrial environments with increasingly strict environmental requirements.

Detailed Overview of Industry and Process Applications

Application IndustryMain Process/StageFunction and Effect
Textile Printing and Dyeing Desizing, scouring, bleaching, mercerizing, and carbonizing pretreatment processes Quickly wet fibers and penetrate deep into the fabric, helping to remove sizing agents, waxes, and natural impurities, improving capillary effect and whiteness, laying a uniform foundation for subsequent dyeing and printing
Leather Chemicals Soaking, degreasing, tanning, and other wet processing stages Accelerate the migration of water and chemicals into the deep layers of leather fibers, efficiently emulsify and remove natural fats, maintain fine grain, and improve leather softness and yield
Metal Surface Treatment Pickling, alkaline cleaning, deep cleaning of precision parts Quickly spread over micropores and gaps on metal surfaces, driving cleaning agents to penetrate under cutting fluids, rust preventatives, and carbon deposits, achieving rapid stripping and cleaning
Pesticide Synergism Formulation of suspension concentrates, soluble concentrates, etc., field application Significantly reduce the surface tension of the spray solution, promote rapid spreading and penetration on hydrophobic leaf surfaces, reduce loss through runoff and evaporation, and increase the deposition and systemic translocation efficiency of active ingredients
Papermaking Industry Pulping and cooking, deinking, sizing, coating, resin control Promote rapid penetration of chemical solutions into fiber cell walls, accelerate reactions or dispersion, improve bleaching efficiency, sizing uniformity, and coating adhesion, enhance paper physical strength
Daily Chemical and Industrial Cleaning Formulation of laundry detergents, hard surface cleaners, heavy-duty degreasers Help active cleaning ingredients penetrate the interface between dirt and substrate, break down stubborn stains, shorten soaking time, enhance deep cleaning effect, and save water and electricity

Application Recommendations

Recommended application methods in different processes:

  • Textile pretreatment: Recommended for use in desizing and scouring baths combined with alkali agents and chelating agents. Its low-foaming property allows stable operation in high-speed equipment, reducing the risk of foam overflow.
  • Leather soaking/degreasing: Can be compounded with non-ionic or anionic degreasing agents, still exhibiting excellent degreasing performance at low temperatures, helping to save energy and reduce consumption.
  • Metal cleaning: Used in combination with pickling or alkaline cleaning systems, especially suitable for deep cleaning of precision parts, effectively removing stubborn oil and carbon deposits.
  • Pesticide formulations: As a tank-mix synergistic adjuvant or built-in formulation component, it is recommended to adjust the dosage according to the spray solution system to achieve optimal spreading effect.

Precautions

  • Storage temperature is recommended to be maintained at 5–35°C. The container should be sealed immediately after use to avoid prolonged exposure to humid air or extremely low temperatures to prevent moisture absorption or freezing.
  • It is recommended to wear chemical safety goggles and nitrile gloves during operation, ensuring good ventilation in the operating area.
  • Low-foaming characteristics do not mean completely foam-free. Under specific temperature and stirring conditions, foam may still be generated. Pre-testing is recommended when compounding.
  • Avoid mixing storage with incompatible substances such as strong acids and strong oxidizers.
