Quick Penetrant Fast T-50H (CAS No.: 577-11-7), also known as Quick Penetrant T, Penetrant OT, Aerosol OT, etc., its chemical component is sodium di(2-ethylhexyl) sulfosuccinate (DOSS), an anionic surfactant. The product appears as a colorless to light yellow viscous liquid, and is a high-performance penetrating auxiliary product from Guoli Chemical Co., Ltd.
The core advantage of this product is its extremely low surface tension, which can significantly reduce the solid-liquid contact angle, thereby imparting excellent penetration rate and good wetting and spreading ability. Even on hydrophobic surfaces, it can quickly penetrate into fibers, porous substrates, and small gaps. In addition, Fast T-50H has good emulsifying ability for oily substances, and also has moderate foaming characteristics, which can be utilized or controlled according to actual process requirements.
It should be noted that Fast T-50H is not resistant to strong acids or strong alkalis, and is most suitable for use under neutral and mild acid-base conditions to ensure optimal performance.
1. Textile Printing and Dyeing: Used as a high-efficiency penetrant in pretreatment, dyeing, and printing processes, promoting uniform diffusion of chemicals along fibers, improving dye uptake and leveling, helping processing enterprises improve efficiency and product quality.
2. Pesticide Formulations: Used as a wetting agent and penetration synergist, significantly enhancing the adhesion, spreading, and penetration ability of the spray liquid on plant leaf surfaces and target biological surfaces, thereby improving efficacy and reducing liquid loss.
3. Leather Processing: Applied in wet processing steps such as soaking, degreasing, and tanning, accelerating the deep penetration of water and chemicals into leather fibers, shortening processing time, and improving leather quality.
4. Daily Chemical and Industrial Cleaning: Functions as a penetrating and detergency agent in cleaning formulations, quickly penetrating under the dirt layer, promoting dirt detachment and dispersion, effectively breaking down stubborn stains, and enhancing cleaning effect.

When using Fast T-50H, it is recommended to formulate it in neutral or mild acid-base systems based on the specific process. In textile printing and dyeing, the recommended application steps are pretreatment, dyeing, and printing; in pesticide formulations, it is added as a synergist; in leather processing, it is suitable for wet processing stages such as soaking and degreasing; in cleaning formulations, it can be compounded with other surfactants to enhance detergency and penetration. The specific dosage should be determined through experiments based on the actual system and process conditions.
