What are the main ingredients of the fast penetrating agent, Quick T-50H?

The main component of Quick T-50H is sodium di(2-ethylhexyl) sulfosuccinate (DOSS), which is an anionic surfactant.

Detailed Description

The chemical composition of the fast penetrating agent Quick T-50H is sodium di(2-ethylhexyl) sulfosuccinate, with the English name Dioctyl Sulfosuccinate Sodium Salt, abbreviated as DOSS. The CAS number of this product is 577-11-7, and it belongs to the category of anionic surfactants.

Quick T-50H has many aliases in the industry, including: fast penetrating agent T, Quick T, penetrating agent OT, wetting agent OT, sodium dioctyl sulfosuccinate, sodium di(2-ethylhexyl) sulfosuccinate, sodium sulfosuccinate dioctyl ester, and the international generic name Aerosol OT or Aerosol OT-50. Its appearance is a colorless to light yellow viscous liquid.

The most prominent characteristic of this product is its extremely low surface tension, which endows it with excellent rapid penetration and superior wetting and spreading ability. It can quickly penetrate various fibers, porous substrates, and tiny gaps, performing exceptionally well even on hydrophobic surfaces. Additionally, it has high emulsifying efficiency for oils and fats, aiding in dispersion and system homogenization.

Application Suggestions

Based on the core component characteristics of DOSS, Quick T-50H is mainly used in the following fields:

• Textile Printing and Dyeing: As an efficient penetrating agent in pretreatment, dyeing, and printing processes, it promotes uniform diffusion of chemicals along fibers, improving dye uptake and leveling properties.
• Pesticide Formulations: Used as a wetting agent and penetration enhancer to increase the adhesion, spreading, and penetration capacity of pesticide solutions on plant leaf surfaces and target organisms.
• Leather Processing: Applied in wet processing steps such as soaking and degreasing to accelerate the penetration of processing liquids into leather fibers.
• Cleaning Agents: In household chemical and industrial cleaning formulations, it serves as a penetrating and decontaminating component, quickly penetrating beneath soil layers to promote removal and dispersion.

Precautions

This product is not resistant to strong acids and bases; it is recommended to use under neutral and mild acid-base conditions to ensure optimal performance. The product is irritating to skin and eyes (GHS classification: Skin corrosion/irritation Category 2, Serious eye damage/eye irritation Category 2). Chemical protective gloves and goggles should be worn during operation. It is toxic to aquatic life; do not discharge the product or its solutions directly into water environments.
