Quick T-70B is a low-toxicity anionic surfactant. When using it, special attention should be paid to protecting the eyes, skin, and respiratory tract. Operate in a well-ventilated area and wear full protective equipment. Strictly avoid ingestion and prolonged contact.

Detailed Description

Quick T-70B (Sodium dioctyl sulfosuccinate, CAS: 577-11-7), although a high-performance rapid penetrant and wetting agent, has certain acute toxicity and irritation. According to product safety data, its acute oral LD50 (rat) is approximately 1900 mg/kg, classified as acute toxicity category 4, harmful if swallowed. Meanwhile, this product is categorized as skin irritation category 2 and serious eye damage/eye irritation category 2, meaning direct contact will cause definite irritation reactions.

In practical use, Quick T-70B may come into contact with the human body in the form of mist, vapor, or splashes, especially during large-scale batching, mixing, or spraying operations, where the risk is higher. Additionally, this product is irritating to the respiratory tract mucosa (specific target organ toxicity - single exposure, category 3). Inhaling its vapor or mist may cause respiratory irritation symptoms such as coughing and throat discomfort. Therefore, ventilation conditions in the operating environment are crucial.

This product maintains excellent chemical stability in acidic, alkaline, and hard water media, but users should not ignore its biosafety. In case of skin or eye contact, immediately rinse with plenty of running water; if swallowed, do not induce vomiting, rinse the mouth immediately and seek medical attention. Overall, as long as operating procedures are strictly followed and personal protection is ensured, Quick T-70B can be used safely and efficiently in various industrial fields.

Operational and Protective Recommendations

Personal Protective Equipment (PPE) requirements: When handling, protective gloves (preferably nitrile or neoprene), protective clothing, safety goggles/face shield, and respirator (especially in poorly ventilated areas or when aerosols are generated) must be worn. After work, thoroughly wash exposed skin; contaminated clothing must be cleaned before reuse.

Operating environment: Use this product only outdoors or in well-ventilated areas. Avoid splashing during batching and feeding. Local exhaust ventilation should be provided for mixing and heating processes. Do not eat, drink, or smoke while using this product. Prominent safety warning signs should be posted in the work area.

Storage requirements: Store in a well-ventilated place, keep container tightly closed to prevent moisture absorption or evaporation. Lock storage area to prevent access by unauthorized personnel. Keep away from strong oxidizers and food. Recommended storage temperature: 5°C~35°C, avoid high temperatures and direct sunlight.

Emergency Handling Guide

  • If swallowed: Rinse mouth immediately, do not induce vomiting. If feeling unwell, call a poison center or doctor.
  • Skin contact: Immediately remove contaminated clothing, rinse skin thoroughly with plenty of water for at least 15 minutes. If skin irritation persists, seek medical attention.
  • Eye contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do so, continue rinsing. If eye irritation persists, seek medical attention.
  • Inhalation: Move the person to fresh air and keep comfortable for breathing. If feeling unwell, call a poison center or doctor.
  • Spill handling: Small spills: absorb with inert material (e.g., sand, vermiculite) and collect into a sealed container. Large spills: dike to prevent entry into sewers and waterways, dispose according to local regulations.

Notes

  • This product is an anionic surfactant. When combined with cationic auxiliaries, precipitation or deactivation may occur. Compatibility testing is recommended before compounding.
  • When used in high-temperature processes such as textile pretreatment or industrial cleaning, pay special attention to the risk of vapor inhalation and strengthen ventilation measures.
  • Disposal of waste liquid and packaging must strictly comply with local environmental regulations; do not discharge into water bodies or soil.
  • Specific treatment measures refer to the product label and Safety Data Sheet (SDS). The above first aid measures are general guidelines; actual situation should be based on doctor's diagnosis.
