Rapid penetrating agent Fast T-50H (sodium dioctyl sulfosuccinate, CAS No.: 577-11-7) is an anionic surfactant. Due to its outstanding rapid penetration, excellent wetting ability, and efficient emulsifying capacity, it has become an indispensable auxiliary agent in multiple industries. Its core advantage lies in its ability to significantly reduce the solid-liquid interfacial tension, allowing the treatment liquid to quickly penetrate into various fibers, porous substrates, and tiny gaps, thereby greatly improving process efficiency and product quality.
This product is suitable for neutral and mild acid-base environments, but its stability decreases under strong acid or strong base conditions. Therefore, attention should be paid to the matching of acid-base conditions during formulation design and process selection. Additionally, Fast T-50H has moderate foaming properties, which can be utilized or controlled by defoaming methods according to practical application needs.
1. Textile Printing and Dyeing: Used as an efficient penetrating agent in pretreatment (scouring, bleaching), dyeing, and printing processes, it promotes the uniform diffusion of dyes and auxiliaries along fibers, significantly improving dye uptake, level dyeing properties, and color fullness, while reducing dyeing defects.
2. Pesticide Formulations: As a wetting and penetrating synergist, it enhances the adhesion, spreading, and penetration of the spray liquid on plant leaves and target surfaces, effectively reducing liquid loss and improving pesticide utilization and control efficacy.
3. Leather Processing: Applied in wet processes such as soaking, degreasing, and tanning, it accelerates the penetration of water and chemicals into the interior of leather fibers, shortens processing time, and improves leather softness and quality uniformity.
4. Daily Chemical and Industrial Cleaning: As a component of penetration and detergency in cleaning formulations, it quickly penetrates the interface between dirt and substrate, dislodging stubborn stains, promoting stripping and dispersion, and significantly enhancing cleaning efficiency.
