Fast T-70B (Dioctyl sodium sulfosuccinate, CAS: 577-11-7) is an anionic surfactant with stable chemical properties, resistant to acid, alkali, and hard water. However, its appearance is a colorless to light yellow transparent viscous liquid with a water content ≤30%. If left open for a long time, water evaporation or moisture absorption may cause concentration fluctuations, so sealing is crucial.
This product is classified as a chemical with certain hazards during storage and use (acute toxicity oral category 4, skin\/eye irritation category 2, respiratory tract irritation category 3). Therefore, the storage area must be locked, away from food, beverages, and animal feed, as well as unauthorized personnel, especially children.
Regarding shelf life, the Guoli Chemical product database does not explicitly indicate a specific number of months or years. According to industry standards, under strict storage conditions as follows, the recommended usage period for such high-efficiency anionic surfactants is usually 12 to 24 months. Users should refer to the batch number and expiration date on the product packaging label as the final basis, and use it as soon as possible after opening to ensure optimal penetration and wetting performance.

This product is widely used in textile printing and dyeing, pesticide formulations, industrial cleaning, petroleum extraction, etc., leveraging its rapid penetration (penetration index ≤5 seconds) and low foam characteristics. To ensure effectiveness, it is recommended to use the entire contents at once or within a short period after opening; if multiple uses are needed, immediately wipe the container opening clean and tighten the seal after each removal to prevent impurities or moisture ingress.
In practical formulation applications, if the product exhibits stratification, abnormal increase in turbidity, or significant decrease in penetration power, stop using it even within the conventional storage period, and contact the Guoli Chemical technical service team for quality review.
