Span S-40 (sorbitan monopalmitate) performs well in terms of environmental compliance. According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), the pure substance is not classified as an environmental hazardous substance, nor does it fall into the categories of physical or health hazards. This indicates that, from the perspective of internationally accepted chemical classification standards, Span S-40 poses a very low risk to the ecological environment.
From the perspective of toxicology and ecological safety, the acute oral LD₅₀ of Span S-40 in rats is greater than 10 g/kg, which is practically non-toxic; the primary skin irritation index is 0, indicating no irritation; and it is neither mutagenic nor teratogenic. The product itself is derived from the esterification of natural fatty acids (palmitic acid) and sorbitol, and its molecular structure determines that it has good biodegradation potential. In addition, the product meets FDA 21 CFR 172.842 and other food additive standards, allowing it to be safely used in food, cosmetics, and pharmaceuticals, which indirectly confirms its high environmental and safety standards.
Regarding the test report, the Guoli Chemical database currently does not provide a downloadable test report file online. Formal batch test reports (COA) are typically included with product shipments and cover key quality indicators such as acid value, saponification value, hydroxyl value, heavy metal content, and arsenic content. To obtain the latest batch environmental compliance test report or third-party testing certification, it is recommended to contact the Guoli Chemical sales or technical department directly. We will provide the corresponding product testing documents based on your specific needs.
