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.
