According to the safety instructions of Guoli Chemical products, Emulsifier OS (Sodium sec-alkyl sulfonate) and Emulsifier MS-1 (Octylphenol polyoxyethylene ether maleate) have generally consistent storage requirements. They must be stored in a dedicated cool, dry, and well-ventilated warehouse, with containers kept sealed to prevent moisture and contamination. Both are classified as non-hazardous goods, safe for transport, but attention should be paid to separate storage from incompatible substances (such as strong oxidants and strong acids), and mixing is strictly prohibited.
Since Emulsifier OS is classified as GHS skin corrosion/irritation category 2, the storage area should be additionally equipped with spill collection materials (such as sand or inert absorbents), and follow the "first-in, first-out" inventory management principle. Emulsifier MS-1 has no hazard classification and low risk, but still needs to avoid extreme temperatures and direct sunlight. Both products may decompose and generate irritating gases when heated in a fire, so the storage environment must be away from fire and heat sources.
Regarding the shelf life, there is no official shelf life data provided in the Guoli Chemical product database this time. According to the industry standard for nonionic/anionic surfactants, under strict compliance with the above storage conditions and keeping the original sealed packaging, the recommended usage period for such products is generally 12 to 24 months. It is recommended that users refer to the product packaging or Certificate of Analysis (COA) for the exact date. After opening, try to use it within 6 months and regularly check for changes in appearance and performance.

Emulsifier OS is irritating to skin and eyes (H315/H319). Operators should wear chemical safety goggles and protective gloves when handling. In case of leakage, collect with inert absorbent materials (sand, vermiculite) to prevent entering drains or surface water systems. Both products must be disposed of by qualified professional waste treatment companies and must not be discharged directly into the environment.
