Quick Penetrant T (Fast T-50) is a highly efficient anionic surfactant, with core characteristics of "high penetration, strong wetting, extreme resistance, and multi-functionality"—it maintains excellent activity even in strong acid, strong alkali, and hard water systems, and is widely used in textiles, pesticides, emulsion polymerization, and other fields.
Detailed Description
Quick Penetrant T (Fast T-50), chemical name Dioctyl Sodium Sulfosuccinate (CAS No.: 577-11-7), is a general-purpose anionic surfactant. It appears as a colorless to light yellow transparent viscous liquid. This product has various aliases in the industry, including Penetrant T, Fast T, Sodium Diisooctyl Sulfosuccinate, AOT, Aerosol OT, etc., and is one of the strongest penetrating agents among industrial auxiliaries.
The biggest highlight of this product is its extremely high penetration efficiency and excellent wetting and spreading ability—it can instantly act on solid-liquid interfaces, achieving deep wetting on hydrophobic surfaces such as fabrics, metals, plastics, and plant leaves, preventing the "bare bottom" phenomenon. At the same time, it performs excellently in emulsification systems, effectively dispersing oils and dirt, reducing agglomeration, and combining multiple functions of penetration, wetting, emulsification, and cleaning.
Particularly noteworthy is that Quick Penetrant T possesses extreme chemical stability: it maintains excellent activity in strong acid, strong alkali, and high-concentration electrolyte (hard water) systems without hydrolysis or precipitation. This characteristic allows it to function stably under harsh process conditions, far exceeding the applicability of ordinary surfactants.

Application Recommendations
According to product characteristics, Quick Penetrant T (Fast T-50) has significant application value in the following five major fields:
- Textile Printing and Dyeing Auxiliaries: Used in pretreatment, dyeing, and finishing processes, significantly reducing the surface tension of the working fluid, promoting rapid penetration of dyes into the fiber interior, improving dyeing rate and levelness, and reducing color spots.
- Pesticide Formulations: As a spreading and penetrating synergist, enhancing the wetting and spreading ability of the pesticide solution on the surfaces of stems, leaves, and insect bodies, making the active ingredient easier to penetrate the cuticle or body wall, improving contact and systemic control effects.
- Emulsion Polymerization: Used as an anionic emulsifier and dispersant, stabilizing monomer droplets, controlling latex particle size, and improving the storage stability and mechanical stability of synthetic latex.
- Leather Treatment Agents: In processes such as soaking, rewetting, degreasing, and fatliquoring, accelerating the diffusion of water and auxiliaries into the leather fibers, shortening process time, and imparting excellent softness and full hand feel to the leather.
- Paper Industry Auxiliaries: Used in internal sizing or surface coating, enhancing uniform penetration and retention of sizing agents and functional auxiliaries, improving paper ring crush strength, water resistance, and printability.
Precautions
- Health Hazards: This product may cause skin irritation (H315) and serious eye irritation (H319). Always wear chemical protective gloves, goggles, and protective clothing during operation.
- Environmental Hazards: Harmful to aquatic organisms (H402). Do not discharge untreated waste liquid directly into public water bodies. Establish a closed system and residue recovery device.
- Storage Requirements: Store in a cool, dry, well-ventilated warehouse. Keep containers sealed, away from heat sources, open flames, strong oxidizers, and strong acids. Store under normal temperature and pressure.
- Emergency Measures: In case of skin contact, flush with plenty of water; if irritation persists, seek medical attention. In case of eye contact, rinse carefully with water for several minutes; remove contact lenses if present and continue rinsing. In case of spillage, contain and collect with inert absorbent materials (sand, vermiculite).
