Tween T-60 (Polyoxyethylene (20) sorbitan monostearate, CAS No.: 9005-67-8) is a mild polyol-type nonionic surfactant. From the perspective of environmental compliance, this product performs well in existing ecotoxicological assessments, with no obvious harm to aquatic organisms. Its acute toxicity is extremely low (rat oral LD50 > 5000 mg/kg), classifying it as practically non-toxic, and under normal use conditions, it does not have special systemic hazards such as carcinogenicity, mutagenicity, or reproductive toxicity, thus ensuring high safety for both the environment and operators.
From a biodegradation perspective, the molecular structure of Tween T-60 contains ester bonds and polyoxyethylene chains, theoretically providing good biodegradation potential, allowing it to decompose gradually in the environment and not easily cause long-term accumulation pollution. However, it should be noted that in spill handling guidelines, Guoli Chemical still requires prohibiting the direct discharge of leaked materials or cleaning wastewater into surface water, groundwater, or sewage pipeline systems. This is a common industry environmental preventive measure and complies with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) management requirements. Therefore, as long as standard operating procedures are followed for use and disposal, Tween T-60 can meet environmental compliance requirements.
Regarding test reports: The Guoli Chemical product database currently does not include specific texts of third-party environmental test reports for this product (such as biodegradability test reports, RoHS testing, REACH compliance statements, etc.). Test reports for chemical products are usually updated with batches. The most accurate approach is to directly request the latest test reports for your required items from Haian Guoli Chemical Co., Ltd., including but not limited to quality indicator data such as heavy metal content and arsenic content (the database already has batch control indicators: heavy metals ≤10 mg/kg, arsenic ≤2 mg/kg).

Given the good environmental properties of Tween T-60, it is widely used in industries with strict safety requirements such as food, cosmetics, and pharmaceuticals. In such applications, it is recommended that formulators follow these principles to ensure environmental compliance and minimize environmental impact: during the formulation design phase, prioritize precise addition strategies to control the dosage of Tween T-60 within the minimum effective concentration range required for the process; during production, avoid leaks and spills, and all cleaning wastewater containing Tween T-60 should be directed to the plant wastewater treatment system, treated to meet standards before discharge.
