Alkyl polyglycoside (APG for short) is a type of surfactant widely used in many application fields, such as medicine, cosmetics, cleaning products and food industries. Alkyl polyglycoside has a wider range of applications and market prospects due to its non-toxic, low irritation and easy biodegradation. The following is a detailed introduction to its safety and environmental compatibility testing:

1. The toxicity of alkyl polyglycosides. According to the regulations of the European Community Economic Cooperation and Development Organization (OECD), the US Toxic Substances Control Regulations (TOSCA) and the Federal Insecticide, Fungicide and Rodenticide (FIFRA), oral toxicity tests on mice and acute toxicity tests on rabbit skin were conducted. The tests showed that the median lethal dose (LD50) was greater than the safety index. Based on this, swallowing and skin contact with alkyl polyglycosides are not dangerous and do not fall into the category of hazard classification or labeling.

2. Irritation and sensitivity of alkyl glycosides. According to the international standard OECD guidelines for testing irritation NO.404, NO.405 and NO.406, the conclusion is that alkyl glycoside APG0810 and alkyl glycosides above C16 are almost non-irritating, and the irritation of APG1214 is within the R38 range. All alkyl glycosides will not cause contact dermatitis on human skin.

3. Biodegradability of alkyl glycosides. Referring to the OECD test methods: rapid biodegradability (screening) test, inherent biodegradability test and simulation (confirmation) test, it is shown that alkyl glycosides are easily biodegradable and biodegrade quickly and completely in all environments.

4. Ecological evaluation of alkyl glycosides. The ecology of alkyl glycosides was evaluated using standard test methods. The results showed that the acute poisoning hazard of alkyl glycosides to microorganisms is almost zero, the chronic toxicity to bacteria is very low, and the toxicity to terrestrial organisms is very low.

5. Environmental hazard analysis of alkyl glycosides, based on the comparison of "predicted environmental concentration (PEC)" and ecotoxicity "predicted no effect concentration (PNEC)", the results show that alkyl glycosides are safe for soil, their industrial application has no side effects on sewage treatment plants, and even large-scale use will not cause any harm to the environment.

Therefore, through the above detailed introduction, it can be seen that alkyl glycosides are safe under any application conditions, will not cause harm to the environment, and have excellent environmental compatibility.
