For AEO, AES, and polyoxyethylene ethers, are there any indicators for residual ethylene oxide and dioxane in the production process or in the testing of the final products?

As the title suggests, for AEO, AES, and polyoxyethylene ethers, are there any specifications regarding residues of ethylene oxide and dioxane in the production process or during final product testing? Thank you!
Yes, but it’s generally not tested!
Could you provide the metrics? Is it a corporate indicator or **does it have an indicator?
Free ethylene oxide is below 1 ppm.
OK, thank you for your reply. What about dioxane?
If you use it for industrial purposes, half of them won’t be tested； If supplying raw materials for cosmetics, dioxane is an indicator that must be tested, as required by cosmetics-related standards.
Expert, could you provide the names or documents of the standards related to cosmetics? I’ll take a look for reference
The \"Requirements for Sodium Lauryl Ether Sulfate Raw Materials for Cosmetics\" adopt the \"Method for the Detection of Dioxanes in Cosmetics\" issued by the **Food and Drug Administration on November 29, 2010 (Document No. Guo Shi Yao Jian Xu 456) as the method for determining dioxanes in sodium lauryl ether sulfate raw materials used in cosmetics.
Yes, different suppliers have different standards; for example, Unilever and Procter & Gamble generally have strict requirements, haha
