Super penetrant JFC-E is a nonionic fatty alcohol polyoxyethylene ether surfactant (CAS: 1639-66-3), known for its excellent wetting and penetrating ability and wide chemical stability. It is a core penetration auxiliary in textile printing and dyeing, leather processing, industrial cleaning, and other fields.

Detailed description

Super penetrant JFC-E (also known as rapid penetrant T, penetrant OT, Aerosol OT, dioctyl sulfosuccinate sodium salt) is a colorless to slightly yellow transparent liquid. This product is a nonionic surfactant with extremely low surface tension, which can impart instant penetrating ability to the working fluid and quickly wet various fibers and substrate surfaces. Its nonionic nature gives it good compatibility with anionic, cationic, and amphoteric auxiliaries, allowing flexible compounding without precipitation.

The outstanding advantage of JFC-E lies in its excellent chemical stability – it maintains stable performance in acidic, alkaline, and hard water systems, adapting to a wide range of process conditions. At the same time, the product exhibits low foaming under the premise of achieving rapid penetration, which is very conducive to continuous production operations. In terms of safety, this product is classified as a non-hazardous material. Acute oral toxicity (rat) LD₅₀ > 2000 mg/kg, indicating low toxicity, and it is safe for humans under normal use conditions.

Main uses

Super penetrant JFC-E, with its super penetrating power and wide applicability, plays an irreplaceable role in many industrial fields:

1. Textile printing and dyeing: This is the most core application area of JFC-E. It serves as an efficient penetrant in pretreatment processes (desizing, scouring, bleaching), accelerating the penetration of chemicals into fibers, improving treatment uniformity and fabric whiteness. In dyeing and printing, it acts as a leveling and penetrating auxiliary, promoting the rapid wetting and penetration of dye solutions into fibers, preventing color spots, improving levelness and color yield, and is suitable for various dye systems. It can also be used in sizing, carbonizing, and other processes.

2. Leather processing: Used in wet processing steps such as soaking, degreasing, and tanning, it significantly accelerates the penetration of water and chemicals into leather fibers, shortening processing time, and improving the softness and fullness of the leather.

3. Industrial and household cleaning: In metal cleaners and hard surface cleaners, it reduces surface tension, enhances detergency and wetting/spreading properties, especially suitable for heavy-duty cleaning systems.

4. Pesticide formulations: As a wetting and penetrating adjuvant, it can be added to emulsifiable concentrates, wettable powders, aqueous suspensions, etc., to improve the wetting, spreading, and penetration of spray liquid on plant leaves and target surfaces, thereby enhancing efficacy.

5. Paper industry: In chemical pulping and wastepaper deinking processes, it promotes the penetration of cooking liquor or deinking agents, accelerating wood chip softening, fiber separation, and ink removal, improving deinking efficiency.

6. Daily chemical products: As an enhancing penetrating component, it is compounded into laundry liquids, laundry powders, dishwashing detergents, etc., to enhance the penetration and breakdown of stubborn stains by the washing solution, improving overall detergency performance.

Application recommendations

JFC-E maintains stable performance in acidic, alkaline, and hard water systems and can be flexibly compounded with anionic, cationic, and amphoteric surfactants. In textile printing and dyeing pretreatment processes, it is recommended to adjust the dosage according to specific process requirements. Generally, a working fluid concentration in the range of 0.1% to 0.5% is sufficient to achieve good wetting and penetrating effects. When used as an efficacy-enhancing adjuvant in pesticide formulations, the recommended addition amount is 1% to 5% of the total formulation weight. Since this product is nonionic, it does not cause precipitation reactions when compounded with various ionic auxiliaries, offering high formulation design flexibility.

Precautions

  • It is recommended to wear chemical safety goggles and protective gloves during operation to avoid prolonged contact with skin and eyes.
  • The workplace should be well-ventilated to avoid inhalation of vapors or mists.
  • The storage temperature is recommended to be between 5 and 35 ℃, avoiding direct sunlight and keeping the container tightly sealed.
  • Store separately from incompatible substances such as strong oxidizers, strong acids, and strong bases.
  • In case of accidental contact with eyes, immediately flush with plenty of running water or normal saline for at least 15 minutes; if irritation persists, seek medical attention.
  • Do not eat, drink, or smoke in the work area; thoroughly wash exposed parts after operation.
